Starting and Charging System
Starting and Charging System 1
Starting and Charging System
ISummary
IStructure outline
Starting system mainly includes battery, ignition switch, starter, starter relay and related lines.
Main components of charging system include: generator assembly (inbuilt voltage regulator), battery, battery
charging indicator light.
Starting System
As main component of starting system, starter consists of direct current motor, electromagnetic switch and
transmission mechanism. Direct current motor lead in current from battery and make driving gear wheel to turn;
transmission mechanism makes driving gear wheel mesh into flywheel gear ring, and also can automatically
disconnect after engine starting; starter circuit is controlled by electromagnetic switch.
Starting system has 2 separate circuits: one is to provide high current to starter, the other is low current control
circuit which controls starter relay.
Charging System
Main function of generator is to provide power to all electrical equipment (except starter) when engine running
normally, and also charge battery. Generator mainly consists of 5 parts: rotor, stator, voltage regulator, end cover.
The rotor and stator generate alternating current with electromagnetic cutting principle, generated alternating current
is transformed into 14V stabled direct current by rectification and voltage stabilization of voltage regulator.
Generator is driven by engine through engine belt and pulley device.
Battery
The vehicle uses free-maintenance battery, whose difference with traditional battery is there is no vent plug on
battery cover, and battery is completely sealed except small vent holes on both sides of battery. Small quantity of
gas produced by battery can be released from vent holes, small amount of gas will be released when electrolyte
inside battery has chemical reactions, and if there is no exhaust vent, internal pressure will increase continuously
along with air increase, and battery shell will crack down when pressure exceeds its limitation.
Compared to regular battery, free-maintenance battery has following advantages:
- No need to add water during battery service life.
- Overcharge protection.
- Power leakage is not as easy as regular battery.
- Smaller weight and volume, large capacity.
Battery has 3 main functions in whole electrical system:
- Supply starting power when engine starting.
- Work as electrical system voltage stabilizer.
- When generating capacity of generator cant satisfy need of electrical system, battery can supply power in a
certain period of time.

IIOperating Principle
Operating principle of starter: Turn ignition switch to START Contact plate connects electromagnetic
switch bolt (at the same time shifting fork knockout gear wheel and mesh with flywheel) Battery positive
electrode (+) supplies power, main current flows into commutator from positive electrode brush Rotor rotates
under the action of magnetic field (Drive planet wheel to turn) small gear wheel move forward along drive
shaft spline Gear drive flywheel to turn engine starts to work.
Operating principle of generator: Generator provides direct current voltage power to vehicle electrical system
and keep battery in charging state. Output of voltage is controlled by voltage regulator. When turn ignition switch
to START, current flows into excitation coil, which is initially motivated. When stator coil starts generating
electricity after engine starting, excitation coil is activated by output current from stator coil. Terminal B supplies
power to vehicle electrical system, and supply charge power to battery. Voltage regulator checks input voltage at
S terminal, and controls output voltage accordingly. If excitation current increases, output power of alternating
current generator increases, otherwise it decreases. When battery voltage (voltage of S terminal of alternating
current generator) reaches about 14.4V regulating voltage, excitation current is cut off. When battery voltage drops
below regulating voltage, voltage regulator regulates output voltage by controlling excitation current to maintain it
in constant level.
When ignition switch is turned on and engine not start, power supply connect to terminal of combination meter
charging indicator light through indoor electrical box, to combination meter terminal, through L terminal of
generator to E terminal to grounding joint, at the same time charging indicator light will be on.
After starting engine, when generator can work normally, voltage of power supply terminal of charging
indicator light is close to L terminal of engine, charging indicator light is off. If charging indicator light is still on

when engine running, it indicates there is fault. If there is no voltage or too high voltage when engine working,
indicating function of voltage regulator will start, and charging indicator light will be on.

ISystem outline
The vehicle applies manual control A/C system. A/C condenser applies supercooled type, thus improving cooling
performance. To enhance defrost performance, when choose mixing and defrost mode, it is manually switched to
A/C mode. Based on the vehicle speed, cooling water temperature, and different pressure of air conditioning
refrigerant, the condenser fan has two speed control modes - low and high speed control. The increase of the
blower air volume and the improvement of the air mixing capability will improve cooling and heating
performance.
Control Type and Performance Description of A/C Control Panel
A/C control applies manual control type, panel is integrated with rear defrost heating switch, panel illumination
applies backlight/LED, button symbol applies spray-paint laser engrave; button and knob function of A/C panel
are shown as picture below.

System Component
1. A/C host assembly
A/C host assembly consists of blower, expansion valve, evaporator, heater and casing. Blower intakes external air and gets
into vehicle through evaporator and heater to realize A/C normal working.
2. Blower
Blower consists of motor and fan, using intake port air door motor to switch internal and external air circulation mode, and
intake internal air and external air. Function of intake port air door motor is realized by internal and external air button of
controller. When in internal circulation mode, intake from two intake port in the side; when in external circulation mode, intake
through filter on front guard cover of vehicle, at the same time using blower inletting air, and carry out heat exchange through
evaporator, refrigerated air getting into vehicle.
3. Speed regulating module
The system uses speed regulating resistance, totally divided 4 grade, not variable speed regulating.
4. Air door motor
Installed in blower assembly, controlled by A/C internal and external circulation selection button, drive internal and external
circulation air door to realize switch of air intake way.
A/C control panel (manual) diagrammatic sketch
Air-conditioning Device
Air-conditioning Device 18
5. Blower motor
Rotating fan forms A/C system required air quantity by vehicle power supply.
6. Evaporator temperature sensor
Detecting temperature of evaporator core, pass signal to controller to
prevent evaporator from freezing. It is installed in evaporator core. Sensor has a
negative temperature coefficient thermistor, thus resistance increase when
temperature decreases, and resistance decreases when temperature rises.
7. Evaporator and heater
Air sent by blower goes through evaporator and gets cooled, some air through the evaporator will be sent to heater core, and
the rest is supplied to upper portion of heater housing, according to opening and closing degree of temperature control damper. In
order to control indoor temperature regulation and air mixing, air from heater core will be mixed with the air of the upper portion
of the housing in the heater housing rear section. Controlled by the mode damper motor, the mixed air is sent to the required outlet
so as to realize the vehicle interior temperature regulation and defrost / defog function. In short, the heater assembly adjusts air
mixing, and controls temperature and wind direction.
8. Mode motor
Installed in the left part of the heater housing, controlled by signal of A/C panel (ETC) mode switch, it can start small motor
inside air door motor to adjust the position of mode air door. When motor starts, changes in the voltage difference will be sent to
ETC, and ETC will judge the feedback signal. When the air door moves to the required position, the motor will stop working.
9. Temperature motor assembly
Installed in the right part of heater housing, controlled by signal of A/C controller temperature knob, it can start small motor
to regulate position of temperature controlled air door. When motor starts, changes in the voltage difference will be reflected to
A/C controller, and A/C controller will judge the feedback signal. When air door moves to required position, motor will stop
working.
10. Condenser and drier
High temperature & high pressure gas refrigerant from compressor will be cooled down at normal temperature. Cooling of
the condenser relies on traveling wind and forced air volume of fan. This model uses a parallel flow condenser, combined with
drying bottles together. Undercooling can improve cooling performance, reducing the amount of refrigerant system needs, and also
reduce number of parts combining with drying bottles. When the system is contaminated, previously drying bottles would be
replaced. But for this model, you can just remove the cap of the lower part of the drying bottle and replace the desiccant.
11. Engine cooling system
After comparing inputted vehicle speed, A/C load, coolant temperature value, engine ECU is divided into two parts (high/low)
to control speed of cooling fan. When vehicle speed signal and coolant temperature sensor failure, driving cooling fan will be high
speed running at the same time. Cooling fan is integrated in front module, switching to high/low speed through collecting coolant
temperature, vehicle speed etc. related information.
Condenser fan equipped with 1.5 engine, when high speed, power is 180220W; when low speed, power is 120150W;
Condenser fan equipped with 1.3 engine, when high speed, power is 140150W; when low speed, power is 120130W.
12. Ternary pressure switch
Ternary pressure switch is to increase the medium pressure switch to conventional A/C binary pressure switch. When the
system pressure rises, the medium pressure switch is activated and sends signals to the engine control unit. At this moment, radiator
fan and condenser fan keep high speed; it can prevent performance degradation caused by the pressure rises. Also, air conditioning
systems will be protected when abnormal pressure (high/low pressure) occurs.

VMaintenance Note
Warning Please obey to the following notes when checking and maintaining A/C system, or else it may cause vehicle
damage and personal injury.
1. Freezing point of refrigerant is low, and volatility is high, thus must use gloves and glasses in order to prevent phenomenon of
skin pernio and blindness due to contact with skin.
2. If refrigerant splashed to eyes or contact with skin, should clean contact part with clean water immediately, and must go to
ophthalmology department and dermatology department to consult. Dont kneading eyes by eyes or handkerchief.
3. When do operation related to refrigerant, place must be ventilated. A large amount of refrigerant discharged in enclosed place
will cause hypoxia phenomenon.
4. Refrigerant discharged permitted amount: 1000ppm (ppm is volume of the material contained in the air of the one million
volume) (4184mg/ ); when discharged amount too much, it may cause heart and cardiovascular system, immune system
abnormal or irritability; respiratory system abnormal or skin disease.
5. When doing operation related to refrigerant, make sure there is no foreign matter of moisture and dust around, this foreign
matter will flow into A/C system and will be harmful to system.
6. When doing operation related to refrigerant, must prepare gas leakagemeter. When R-134a refrigerant contact with high
temperature obstacle, it will produce harmful gas, therefore pay attention to prevent leakage.
7. A/C system of the vehicle must use R-134a refrigerant. If using other refrigerant, it will cause bad influence to system
component.
8. R134a refrigerant and R-12 refrigerant are imcompatible, thus little amount cant be mixed.
9. When doing operation related to refrigerant, make sure there is no pyrophorus or combustible obstacle around vehicle, and pay
special attention that refrigerant jar will cause bomb in heat source.
10. R134a container is high pressure state, must not be placed in high temperature environment, and must check whether storage
environment temperature is under 52.
11. A/C component generally uses dustproof cover in order to prevent drainage, dust, moisture flowing in. Dustproof cover should
be removed before operating and sealed after operating.
12. Synthetic oil (PAG) with R-134a is more easier to absorb water than R-12, and absorptivity is 10 times higher than mineral oil
(MINERAL). Too much water will infect compressor, lubrication function and durability.
13. Influence of moisture to A/C system is very bad, therefore its better to avoid operation in rain day.
14. When A/C system re-installed after removed, should spread refrigeration oil to O-type seal ring, especially bolt-type
connection part, should first be installed manually and then assemble with two spanners.
15. When assembling flange-type connection part, should push pipe slightly and connect nut and bolt.
16. When installing A/C, assembling with torque more than required torque or force of clamping O-type seal ring too large will
cause refrigerant leakage, therefore operate according to required.
17. Hose cant be distorted.
18. Dont separate A/C system before recycling refrigerant absolutely. If separated before recycling, it will discharge refrigerant
and refrigeration oil under the influence of system pressure, and it may pollute environment.
19. When replacing A/C component, must fill refrigeration oil (type: PAG) when filling refrigerant and refrigeration oil.

Close
Open
2. Operations of discharging refrigerant
1). Connect the refrigerant filling instrument to the system.
2). Put a clean rag in the open part of central hose.
3). Gradually open the high pressure manual valve to discharge refrigerant.
Caution Exhausting gas velocity too fast may result in the discharging of the refrigeration oil from the compressor.
4). Check if there is the trace of refrigeration oil on the rag. If there is the trace, slightly close the manual valve.
5). When the filling instrument ruler decreases to 3.5kg/c, slowly open the low pressure manual valve.
6). To reduce the system pressure, slowly open the high pressure and low pressure manual valve until the ruler indicates 0kg/c
.
3. Vacuum operation for refrigeration system
Caution System must be vacuumized after discharging refrigerant. This operation is supposed to exclude the air and
moisture in the system, and it should be started in 15 minutes after all the parts are installed.
1). Confirm if the engine stays in shut down.
2). Connect the filling instrument to the compressor contact joint, and
close the two ends.
3). Confirm if the refrigerant is excluded from the system.
4). Central pipe is connected to the intake port of the vacuum pump.
5). Open the high pressure/low pressure valve of the filling instrument
after operating the vacuum pump.
6). After 10 minutes, the low pressure detector scale should be higher
than 0.96kg/c vacuum. Otherwise, the system has leakage and
should be repaired as following steps.
-Use refrigerant container filling system.
-Use leakage detector to check the leakage. If the leakage if detected,
repair it.
-Exclude the refrigerant and vacuumize the system.
- If the leakage does not occur, continue to vacuumize.
7). Operate the vacuum pump again.
8). Filling instrument scale for both ends should keep 0.96kg/c vacuum.
9). Continue to vacuumize until the ruler indicates 0.96kg/c.
10). About 15 minutes after the implementation of vacuum operation, close the pressure valve of the filling instrument and stop
vacuumizing; separate pipes from the pump. In this way, refrigerant can be added.

4. Use refrigerant control valve
1). Before the valve is connected to the refrigerant container, completely turn the handle counterclockwise.
2). Turn counterclockwise until the disc reaches the highest position.
3). After connecting of the central pipe to the valve device, rotate the disc clockwise by hand.
4). Turn the handle clockwise and dill hole in the upper portion of
the sealing part.
5). Loosen the nuts connecting the filling instrument center
connector and pipe.
6). After a few seconds of exhaust, tighten the nut.
5. Adding refrigerant (Gaseous state)
Caution This operation is by means of the device on low
pressure side to add the gaseous refrigerant into the system. At this time the refrigerant
container should be put vertical so that the gaseous refrigerant would flow into the system.
1). Install the refrigerant container on the adjusting valve.
2). Open the low pressure valve; adjust the valve until the low pressure scale stays below 4.2kg/m
2
.
3). Start the engine and start the air condition.
Caution To prevent the liquid refrigerant flows into compressor through the intake port, put the
container vertical.
4). When add the regulated amount of refrigerant, close the low
pressure valve.
Regulated amount of filling refrigerant: 460±20g
5). If the refrigerant filling speed is too slow, you can put the
container into a container of water of about 40 .
Caution Under any circumstances, do not keep the water
heated to above 52 , and hot light should not
touch the container.

6. Adding refrigerant (liquid state)
Caution This operation is by means of high pressure side filling. Upend the refrigerant container so that
the refrigerant would flow into the system.
1). After the system is vacuumized, completely close both ends of high/low pressure valve.
2). Install the adjusting valve of refrigerant container.
3). Upend the container after the high pressure valve is fully opened.
4). The exclude pressure will increase when the system is over filled. Therefore, when measure the refrigerant weight, fill with
correct amount and close the high pressure valve.
Regulated amount of filling refrigerant: 460±20g
5). After adding regulated amount of refrigerant, close the filling instrument valve.
6). Use leakage detector to check if there is leakage.
Caution When use high pressure side filling, the engine will not be started. By use of liquid refrigerant
filling, low pressure valve cannot be opened. Performance test should be conducted before
separating the filling instrument.

Generally, auxiliary restriction system indicates whole safety airbag system, and there are “SRS” marks on trim cover of
airbag or where there are airbags;
1Driver Airbag - DABDirectly protect driver’s upper body when serious front collision happened, and it can stop
driver from moving forward in some extent. Usually this kind of airbag is installed inside steering wheel, and trim cover of DAB
is horn cover on steering wheel;
2Passenger Airbag - PABDirectly protect passenger’s upper body when serious front collision happened, and it can
stop driver from moving forward in some extent. Usually this kind of airbag is installed inside dashboard of front passenger’s
side, and there are visible type and hidden type;
3Side Airbag - SABMainly supply extra protection to front driver and passenger. Protect chest of front driver and
passenger and hip of person in vehicle collision side.
Caution When driving, please fasten safety belt as required. Protection effect will not be obvious when only using
airbag, and in some sense, using airbag without main restriction system (safety belt) will cause passenger more
harm. Safety airbag is auxiliary device of safety belt, and can’t replace safety belt.

IIPrinciple of Airbag System
Operation Condition of Airbag
30° 30°
Front impact with enough strong impact force happened in the area of 30°range of vehicle centerline can make airbag work.
Operating Principle of Airbag System
When vehicle happened collision, collision between vehicle and obstruction is called first collision, which can cause vehicle
speed decrease suddenly; collision between passenger and inner structure of vehicle is called second collision. Before passenger in
vehicle and structure component of vehicle happened second collision, rapidly insert airbag full of air between passenger and inner
structure component of vehicle, and absorb kinetic energy of passenger by airbag breathability and exhausting throttling effect, and
this can slow down violent impact and separate passenger and inner structure component to protect passenger.
Airbag, seat and safety belt constitute vehicle restriction system.

IIFunction Requirement
Wiper System
1. Front Wiper Control
BCM controls wiper motor and water spraying pump by monitoring state of wiper switch and combination switch, and
realizes all working mode of wiper system: front wiper low speed working, front wiper high speed working, front wiper
intermittence working, front wiper closed, front windshield spraying water etc..
1) When ignition switch to “ON”, front wiper controlling switch connects to high speed/low speed/intermittence position,
namely corresponding switch on, thus front wiper performs corresponding action.
2) When wiper switch is in intermittence position, Intermittence regulating time has 5 gears. Intermittence regulating time
shown as below:
When vehicle speed is higher than 60km/h (can equipped with 60km/h or 100km/h, default 60km/h), if use intermittence
mode, reduce 4s on the set time.
Vehicle speed treatment: received signal on network is 15 bits, valid value range is 0x0-0x14D5, ratio coefficient is
0.05625.
3) Wiper high/low speed control: when switch connects to low speed position, low speed relay actuated, motor works in
low speed. If switch connects to high speed, high speed relay actuated, motor works in high speed.
4) When inching switch works, low speed always works.
5) Front spraying water is less than 400ms, wiper not works; when more than 400ms, wiper always work with spraying
water, and then wiping three times after water spraying stopping.
6) Front wiper resetting control: After switch is off, when motor is not running to initial position, BCM not receives
resetting position signal, high speed relay cut off, low speed relay not cut off, and motor continues to work; when motor runs to
initial position, resetting switch is actuated, BCM receives resetting position signal, low speed relay cuts off, and motor stops
running.
BCM Device
BCM Device 84
7) When in intermittence position, water spraying is prior.
8) Wiper high speed running period is 1s, and low speed running period is 4/3s.
Emergency strategy When running, if detecting front wiper resetting switch not change for 18s, it can judge that motor
gets stuck, and close output. At the same time only when ignition switch one circulation of ON-OFF-
ON or wiper switch connect to other switch position from OFF, it can restart wiper.
2. Rear Wiper Control
BCM controls wiper motor and water spraying pump by monitoring state of wiper switch and combination switch, and
realizes all working mode of wiper system: rear wiper and rear wiper spraying water etc..
Rear wiper can be configured to be there is or not by diagnosis, default is open rear wiper.
1There are only “ON” and “OFF” in rear wiper, and it always wipes in low speed when in “ON”;
2Rear wiper doesn’t work after rear water spraying switch is on for less than 600ms, rear wiper works a wiper period at
least after the switch is on for 600ms;
3When spraying water time is more 3s than a wiper period, it wipes a period.
Light Control
1. Keyhole Illumination Light Control
Keyhole illumination is mainly to be convenient to insert key for customer. When key not inserting ignition switch, driver’s
side door is open, keyhole illumination light is on; when turning ignition switch to “ON”, keyhole illumination light will be off,
and after door is closed, keyhole illumination light is on for 10s and then off.
2. Position Light Control
Indoor top light is to illuminate when driver and passengers getting into vehicle or inside the vehicle.
1) When door light is in automatic position and satisfies one of the following conditions, interior light will be immediately on:

2) When satisfying one of the following conditions, interior light will be off gradually:
1After undefended successfully, interior light will be on for 30s and then off gradually;
2When open vehicle door from closed state, interior will be on for 30s, and then off gradually;
3) When satisfying the following conditions, interior light will be off immediately:
1When open vehicle door from closed state, interior is on continuously, if door is open for more than 15min, interior
will be off immediately;
2When defended successfully, interior top light will be off immediately, immediately off after defended successfully
is prior to interior light working 30s and then off gradually after undefended successfully;
3When four doors are closed, ignition switch is in “ON”, interior light will be off immediately;
4) Collision signal detonates interior light on:
1 When collision signal is effective, interior will be on immediately;
2After collision signal detonating interior light on, if ignition switch is turned from “OFF” to “ON”, interior light will
be off immediately. Interior light gradually off time is 5.5±0.5s.
3. Day Driving Light Control
Day driving light is to warning when driving in daylight. Day driving light can be configured to be there is or not by
diagnosis, default is open day driving light. Used to enable control of day driving light:
1When turning ignition switch to “ON”, put down manual brake, position light has no output, then day driving light
will be on;
BCM Device
BCM Device 85
2When ignition switch is not in “ON”/ “ST” or manual brake is not pulled up or position light has output, day driving
light will be off;
4. Position Light Control
Position light is to shown width and indicating. Position light has high and low configuration.
Low Configuration:
When ignition switch is in any position, position light switch input is effective or automatic light requesting position light
on, position light, license plate light and backlight output is on; when position light switch input is ineffective and automatic
light requesting position light off, position light, license light and backlight output is off.
When position light switch input is still effective, if left front door is open, pull out key, small light will be off immediately;
if left front door is closed, pull out key, small light will not be off; left front door open, small light will be off, and it will be
on when key inserted.
High configuration (with PEPS) :
When ignition switch is not in OFF, position light switch input is effective or automatic light requesting position light on,
position light, license plate light and backlight output is on; when position light switch input is ineffective and automatic
light requesting position light off or ignition switch is in OFF, position light, license plate light and backlight output is
closed.
5. Rear Fog Light Control
Rear fog light is mainly to warning in foggy weather. Rear fog light will be on when satisfying the following conditions:
Open Condition:
Ignition switch is in “ON”, at least one of front fog light, low beam light or high beam light is on, and rear fog light
(transient state) is effective.
Closed condition:
1When position light is off or rear fog light switch is off, rear fog light is off;
2Ignition switch is turned to other position except “ON”;
4. Emergency Strategy
States of rear fog light are the same before and after starting.
6. Front Fog Light Control
Front fog light is mainly to warning in foggy weather. Front fog light can be configured to be there is or not by diagnosis,
default is open front fog light.
1 When ignition switch is in “ON” and position light is on, press front fog light switch to open front fog light. Front
fog light switch is normal state switch;
2 When position light is off or front fog light switch is closed or ignition switch is turned to other position except
“ON”, front fog light will be off.
7. High Beam Light Control
High beam light is mainly to illuminate distance in night.
To BCM, overtaking light and high beam light uses one input, in which overtaking light can mechanism automatically
return. High beam light function description are shown as below:
1) When ignition switch is in ‘ON”, and low beam light switch is on or [automatic light switch is on and BCM judging it
is night through value of sunshine sensor] (even low beam light is not on), BCM output high beam light enable low
effective signal, the signal connect back to high beam light switch through wiring harness;
2) When ignition switch is in “ON”, and high beam light enable signal is effective, open high beam light switch, high
beam light is on;
3) When high beam light switch is closed, or ignition switch is not in “ON”, or high beam light enable signal is
ineffective, high beam light is off;
4) Anytime, when high beam light is on, low beam light is on at the same time. Whether high/low beam light is on at the
same time can be decided by configuration, default is high/low beam light on at the same time.
8. Low Beam Light Control
Low beam light is mainly to illuminate vicinity in night. Front headlight mechanism structure is: when turning to low beam
light, position light switch is on.
BCM Device
BCM Device 86
Low beam light function is described as below:
1) When ignition switch is in “ON”, and BCM detecting low beam light switch input is effective, low beam light is on.
2) When ignition switch is in “ON”, and BCM detecting low beam light switch input is effective and automatic light
requesting headlight on, low beam light is on.
3) When ignition switch is in “OFF”, overtaking light switch turned from “ON” to “OFF” denotes the function of
“taking me home”, one ignition circulation denotes one “taking me home” function, enable the function of “taking
me home” again when ignition state turned to “OFF” next time, low beam light is continuously on for 30s.
4) When ignition switch is in “ON”, and low beam light switch is on or [automatic light switch is on and BCM judges
it is night by value of sunshine sensor] (even low beam light is not on), BCM output high beam light to enable
effective signal, the signal connects to high beam light switch by wiring harness.
When in the condition 1 above, low beam light is closed when detecting corresponding low beam light switch is closed.
When in the condition 2 above, low beam light is closed when automatic light switch is closed or request signal is valid.
When in the condition 3 above, low beam light is closed when time is up or ignition switch is turned to “OFF”.
Note: Automatic light request signal is valid indicates light “AUTO” is valid, sunshine signal gets up to light threshold value
requirement. For automatic light strategy please refer to “automatic light”.
9. Automatic Light Control
Function of automatic light is to lit position light and low beam light when light outside is dark and light control switch is in
automatic position. Automatic light function gets to know outside condition by sunshine sensor.
Two EEPROM can be equipped with threshold
AutolampDay_Cfg: range is 0-5V, initial value is 1.8V (specific corresponding initial threshold is supplied by sensor),
AutolampNight_Cfg: range is 0-5V, initial value is 1.2V (specific corresponding initial threshold is supplied by sensor).
1. When BCM power on to initialization, default the night;
2. When input voltage of automatic light sensor is higher than AutolampDay_Cfg, judge it is daytime;
3. When input voltage of automatic light sensor is lower than AutolampDay_Cfg, judge it is nighttime;
10. Brake Light Control
Brake light is mainly to lit the light when braking. When ignition state is in any position, braking switch is valid or braking
request on network is valid, thus open brake light and high position brake light, brake light and high position brake light are
controlled partly.
When in normal mode, brake light and high position brake light can both open through MCU control or brake switch
control.
When in limphome mode, brake light and high position brake light should can be controlled by brake switch.
11. Turning light and Hazard Warning Light
Turning light mainly consists of left front turning light, left side turning light, left rear turning light, left turning indicating
light, right front turning light, right side turning light, right rear turning light, right turning indicating light. When working,
turning light twinkles with the frequency of 90±10 times per minute. Time of on and off are the same. Left front turning light, left
side turning light and left rear turning light merge one way output, right front turning light, right side turning light and right rear
turning light merge one way output, and left turning indicating light and right turning indicating light transmit to meter by CAN.
1 When ignition switch is in “ON”, turning switch is connected or disconnected, thus corresponding turning light twinkle
or closed, and at the same time denotes or connect to tell-tail light on dashboard and flashlight relay twinkle and tweet in the
same frequency;
2 When turning light switch is turned to left or right, BCM drive corresponding turning light to activate to twinkle 3
times at least;
3 When turning light is closed after activating, turning light will be closed after completing its incipient minimum three
times twinkle periods.
4 When turn turning light switch from left to right after left turning light is activated, left side turning light will be off,
and right side turning light will be on.
5 When turn turning light switch from right to left after right turning light is activated, right side turning light will be off,
and left side turning light will be on.
6 Hazard warning light includes two side turning light, key in any position all can drive these turning lights to warning,
corresponding switch is self-lock switch.
BCM Device
BCM Device 87
7 When ignition switch is in “ON”, warning light is prior to turning light, specified instruction are shown as below: if
turning light is on, open warning light switch, then warning light is on instead of turning light, and system gets back to
turning light on state until warning light switch is off; if warning light is on, turn turning light switch to left or right, then
turning light is on instead of warning light, and system gets back to warning light on state until turning light output is closed
or ignition switch is turned from “ON” to “OFF”.
8 If receive collision signal, all lights work at least 5s in warning light state, and pressing warning light switch again after
5s will close warning light, which is to prevent warning light switch being pressed due to collision; when detecting ignition
switch is turned from “ON”-“OFF”-“ON”, collision is removed, warning light recover to normal work.
9 When turning light reports fault due to short circuit to grounding or overload, short circuit state will be recorded to
memory through relevant DTC, and disconnect the side turning light high side drive core immediately, turning indicating
light on combination meter will be off; if turning light is on again and don’t carry out corresponding operation during this
time ignition circulation, must restart ignition switch once (ignition switch ON-OFF-ON), thus output can recover to normal.
10 When working in turning light working mode, some side turning light reports fault due to open circuit or short circuit
to power supply, open circuit state will be recorded in memory through relevant DTC, and the side turning light will twinkle
with double frequency, turning indicating light on combination meter will twinkle with double frequency. Must restart
ignition switch once (ignition switch ON-OFF-ON), thus output can recover to normal; or open circuit fault is removed
during this time ignition circulation, which can recover to twinkle with normal frequency.
Note: Parts marked red indicate that it can close warning light signal after collision signal happened 5s.
12. Power Saving Control
It is mainly to save battery power.
1If detecting any signal change when BCM is in “OFF”, connect power saving relay immediately, and recover supplying
power:
· Any door state signal of four doors
· Remote control unlock signal
· Central control unlock signal
· Ignition state signal
· Mechanism key unlock signal
2After connecting power saving relay, all signals above don’t change, thus close power saving relay after 15 min.
3After connecting power saving relay, detecting any signal above changing again, thus start 15 min timing again.
4When ignition switch is in “ON”, “ACC”, “START”, power saving relay is always actuated.
5After BCM getting into dormancy, close power saving relay.

1. Remote Control or Mechanism Key Lock
When defended, whether horn tweets is achieving by configuration, default not tweet.
When in undefended state, after BCM receiving valid remote control lock signal or driver’s side mechanism key lock signal,
if five doors and engine hood cover are all closed, four door are lock, two side turning lights twinkle once, twinkle period is 1s, in
which 0.5s on, 0.5s off, horn tweets 10ms. If BCM receiving remote control unlock order in twinkling period, light twinkling turns
into unlock twinkling procedure; if any other door is not closed after driver’s side door closed, lock motor works, turning light not
twinkles. After all doors are closed, perform confirmed action again (if there is key inserting, left front door open or central control
unlock/lock, cancel performing confirmed action again), namely two side turning light twinkle once, twinkle period is 1s, in which
0.5s on, 0.5s off, and horn tweets 10ms.
When in defended state, after BCM receiving valid remote control lock signal, BCM still carry out lock action, and perform
confirmed action, namely lock motor works, two side turning lights twinkle once, twinkle period is 1s, in which 0.5s on, 0.5s off,
and horn tweets 10ms.
2. Remote Control or Mechanism Key Unlock
When defended, after BCM receiving valid remote control unlock signal or driver’s side mechanism key unlock signal, four
doors unlock, BCM is undefended and perform confirmed action, namely two side turning lights twinkle twice and then off. Each
twinkle period is 1s, in which 0.5s on, 0.5s off, and horn tweets 10ms.
When undefended, after BCM receiving valid remote control unlock signal or driver’s side mechanism key unlock signal,
BCM is undefended and perform confirmed action, namely two side turning lights twinkle twice and then off.
In undefended state, after BCM receiving valid remote control unlock signal or driver’s side mechanism key unlock signal,
BCM unlock, two side turning light correspondingly twinkle twice.
3. Automatic Lock Function
When vehicle speed up to presetting value n (there are 40kn/h and 15km/h in EEPROM, default value is 15km/h, realized by
configuration), if driver’s side lock motor is unlock, when driver’s door is closed, BCM will automatically lock vehicle door.
4. Re-defended Function
If there is not 5 doors and engine hood cover opening or key inserted ignition switch, then try to lock by remote control (Please
refer to remote control lock).
5. Remote Control Tail Door Unlock
After receiving remote control tail door open signal in defended state, relieve defended state; after receiving tail door unlock
signal in 30s, carry out 500ms open tail door motor; When not open rear tail door over 30s or open rear tail door and then close
rear tail door, get into defended state again, and can’t unlock through tail door unlock signal.
In undefended state, if driver’s side door lock is locked, after receiving remote control opening tail door signal, receiving tail
door unlock signal in 30s, carry out 500ms open tail door motor; When not open rear tail door over 30s or open rear tail door and
then close rear tail door, get into defended state again, and can’t unlock through tail door unlock signal.
In undefended state, if driver’s side door lock is locked, after receiving remote control opening tail door signal, carry out
500ms opening tail door motor. Remote control opening tail door signal is prior to judgment of driver’s side door lock state.
6. Central Control Unlock/Lock Function
When in defended state or warning state, central control unlock/lock is invalid.

IIITechnical Parameter
1. Dormancy and Arouse Strategy
Three conditions satisfying at the same time can get into dormancy state
1. Function satisfies dormancy condition;
2. CAN network satisfies dormancy condition;
3. LIN network satisfies dormancy condition.
In which function satisfies dormancy condition is
1Pull out key (this condition only for BCM without PEPS), there is no output in interior/exterior light and front/rear wiper,
there is no output request in door lock, anti-theft warning is not triggered, rear defrost is not open, and electrical power window is
not enabled. Last 60s and not change.
2BCM is not in diagnosis mode
Before BCM getting into dormancy state, close all output signals. After getting into dormancy, all input signals can arouse
BCM from dormancy.
1Switch signal: key inserting signal, IG2, IG1, ACC, hazard warning light switch, position light switch, mechanism key
lock/unlock switch signal, four doors+ engine hood cover+ rear trunk door state switch, rear trunk unlock switch, driver door lock
state, brake light switch, central control lock
2CAN network Including PEPS signal):CAN interrupt arouse
3RKEThere is remote control order
4DiagnosisGet into diagnosis mode
LIN arouseAfter BCM arousing, LIN arouses.
2. Bus and Diagnosis
BCM supplies diagnosis of CAN-line to be convenient to maintenance of BCM. Diagnosis parts need the following functions:
· Parameter configuration EEPROM read/write
· Read DTC and clear DTC
· IO Control
· BCM controller information
· Off assembly line matching function
· ECU reset
BCM Device
BCM Device 91
Support one CAN bus to be as terminal nod on network, and don’t use network terminal (namely there is no terminal
resistance) in this project, one LIN bus to be as network main nod.
3. Voltage Abnormal Treatment Strategy
Normal working voltage of BCM is 9V-16V, and is carried on according to voltage management strategy established by
platform, and there are five states:
Normal voltage: 9-16V;
High voltage: higher than 16V momently, more than 40ms, but back to normal voltage in 440ms;
Low voltage: lower than 9V momently, more than 40ms, but back to normal voltage in 80ms;
Overvoltage: higher than 16V for long, more than 440ms, but don’t back to normal voltage;
Undervoltage: lower than 9V for long, more than 80ms, but don’t back to normal voltage;
1. Permit to output in the state of normal voltage/high voltage/low voltage
2. Close output in the state of overvoltage/undervoltage, recover output after system voltage back to normal.
Working voltage range of CAN network: 7-17.5V; working voltage range of LIN network: 7-16V; working voltage of
DTC: 8-16V.
4. Short Circuit and Open Circuit Protection Strategy
To high side output, detect short circuit and open circuit when On-stage. Once detecting short circuit or open circuit, counter
starts to counting, and when gets up to a certain value, it can be judged as open circuit or short circuit, and display corresponding
DTC. When detecting short circuit to power supply, once detecting short circuit to power supply, counter starts to counting, and
when gets up to a certain value, it can be judged as short circuit to power supply, and display corresponding DTC.
To SPI low side output, we only need to read diagnosis information of its storage to judge.
When in Off-stage, if diagnosis bit is low, it indicates output is open circuit, and counter starts to counting at the same time,
and when gets up to a certain value, it can be judged as open circuit, and display corresponding DTC. When in On-stage, if diagnosis
bit is high, it indicates output is short circuit to power supply, and counter starts to counting at the same time, and when gets up to
a certain value, it can be judged as short circuit to power supply, and display corresponding DTC.
5. Remote Control and Learning Code
To high configuration vehicle with PEPS, BCM doesn’t supply remote control function; to low configuration vehicle without
PEPS, BCM supplies remote control function.
BCM module includes remote control module, used radio frequency is 433.92MHz±100kHz. There are 3 buttons on remote
control key, including four doors unlock function, four doors lock function, and tail door unlock function.
When waiting for first key learning, right turning light is always on; when waiting for second key learning, right and left
turning light are always on; when learning success, right and left turning light are off. Through diagnosis order or when fixed time
is up, then exit learning state, remote control matching finish.
1. Once Routine can learn two keys.
2. If Routine time is more than 2 minutes, BCM exit this time Routine, and learned successful key will be wrote to EEPROM.
3. As long as key learn successfully, older keys will lose efficiency totally.
4. Press any key to learn code.
5. There are 2 exiting conditions: one is 2 minutes time, the other is diagnosis finishing order.
Ensure remote distance to be 20m. First develop without exterior antenna, and add exterior antenna if vehicle test not satisfy
with customer’s requirement.

IStructure Outline
1. Light Control Switch
Control left/right turning light, front headlight, front fog light, side turning light, overtaking light signal. In the mode of front
headlight working, there are two functions, namely high beam changing to low beam, low beam changing to high beam.
1 Turning light
There are two upward (right turning) and two downward (left turning) position on turning signal operating lever. These
positions are used to transmit turning signal.
Push operating lever upward or downward to send turning signal. When turning is over, operating lever will automatically
return. Arrowhead on combination meter will twinkle, displaying turning direction.
If need to send turning signal or changing road signal, pull operating lever upward or downward to the end. When turning
finish, operating lever will return automatically. When driver send turning or changing road signal, if turning arrowhead twinkling
too fast, it indicates signal light may be damaged, other driver will not see sent turning signal. If some lamp bulb is burnt, please
replace to avoid traffic. When driver send turning or changing road signal, turning arrowhead on combination meter not twinkle,
please check whether lamp bulb is damaged, and then check fuse.
2Front headlight/Low beam light converter
If switch headlight from low beam to high beam, pull turning signal/multifunctional operating lever away from driver. When
high beam is on, if ignition switch is on, combination meter will display high beam light signal.
If switch headlight from high beam to low beam, pull turning signal/multifunctional operating lever to driver.
3Overtaking twinkle
The function can send overtaking signal to drivers in front by high beam headlight. When use the function, pull signal/
multifunctional operating lever to driver until headlight high beam is on, and then loosen operating lever, headlight off.
4) Front fog light
After turning front fog light switch to ON, front fog light is on, and display front fog light signal on combination meter.
Only when front fog light switch is ON can operate rear fog light switch on combination meter to make rear fog light on.
2. Wiper Control Switch
1Operate mode of controlling wiper (Wiping, intermittent, low speed, high speed).
When wiper is in intermittent position, there are five kinds of intermittent time regulating.
When turn ignition switch to ON, can operate front windshield wiper. Use right side operating bar of steering column to
operate front windshield wiper.
HI (High)Turn operating bar to this position, can carry on high speed wiping.
LO (Low)Turn operating bar to this position, can carry on stably low speed wiping.
INT (Intermittent): Turn operating bar to this position, can select delayed wiping one circulation.
Turning middle of wiper operating bar to LO can increase delayed time, and turning to HI can decrease delayed time. Only
when operating bar in INT can regulate wiping speed.
2Front windshield washing liquid

Reversing Radar Device
ISummary
IStructure Overview
Reversing radar device consists of sensors, controller and buzzer (integrated in meter). Reversing radar device is based on the
principle of ultrasonic distance measurement and computer data fuzzy processing technology to determine whether there are
obstacles in the vehicle reversing direction and prompt the distance of the nearest obstacle. When the steering gear hanging in
reversing, reversing switch on, reversing light on, controller receive reversing signal, control ultrasonic sensor send out ultrasonic
signal, based on the principle of self-sending self-receiving and multiple sending single receiving, send echo signal to controller
accurately and completely. After controller analyzing and processing, judge whether there are obstacles within detection distance
and the distance of nearest obstacle, and establish communication with buzzer. According to the different range of distance, send
different frequency tweet to prompt obstacle distance, aiming to security warming.

Engine Anti-theft System
ISummary
IStructure overview
Engine anti-theft system is through two electronic encryption ways, namely Transponder and anti-theft controller (IMMO),
IMMO and ECM, to achieve anti-theft function. After IMMO through wireless authentication with Transponder, wired
authentication with ECM, and if is authentic, ECM will ignition and injection fuel normally; if not, vehicle will not start, thus to
achieve encryption anti-theft to make vehicle more reliable and safer.
Anti-theft system consists of 4 units: anti-theft indicating light (integrated in dashboard), anti-theft controller, transponder and
anti-theft interaction coil; detail constitution is shown below:

IIOperation principle
When turning key from OFF to ON, electronic anti-theft controller assembly outputs anti-theft authentication signal,
transforms anti-theft authentication signal to corresponding magnetic field through electronic anti-theft interaction coil,
transponder obtains energy and information in magnetic field, and produces magnetic field by interior coil after deciphering and
encrypting information, electronic anti-theft interaction coil transforms magnetic field produced by transponder to electric signal,
and transports the signal to electronic anti-theft controller assembly. Electronic anti-theft controller assembly deciphers and
certificate after receiving transponder information, if data is coincident, authentication is passed, or else authentication failed.

IIOperation Principle
IIIMaintenance Note
TPMS system is Tire Pressure Monitoring auxiliary System, the transmission of signal complete through high frequency
signal. When high frequency signal is interfered by same frequency electromagnetic field, and at interfered status for long time, it
will send system failure warning; when vehicle drive away from strong electromagnetic field, warning status will be removed
automatically, it is normal.
When driving on bumpy road, vehicle turning, all tires stress differently, causing tire pressure too high or too low in the
meantime, system sometimes will warning occasionally. When driving on flat and straight road, if pressure is normal, it will
remove warning, it is normal.
When parking vehicle for a long time, tire pressure is normal and there is no obvious change, and doesnt receive any sensor
data in continuous 20min, TPMS indicating light will be on; after vehicle driving, sensors start to transmit data, TPMS indicating
light will be off, which is normal.

When vehicle stop(ignition switch to
ON/START), tire has decompression,
causing pressure too low.
Inflate tire to actual air pressure value.
(There is tire pressure on tire pressure
label)
When vehicle stop(ignition switch to
ON/START), tire pressure too high, causing
pressure too high.
Inflate tire to actual air pressure value.
When driving on bumpy road, vehicle
turning, all tires stress differently, causing
tire pressure too high or too low in the
meantime.
Drive to flat and straight road, if pressure
is normal, it will remove warning
automatically.
When driving, detected tire pressure not
enough (tire not inflated for a long time or
tire damaged causing air leakage).
Must stop vehicle as soon as possible and
check all tire and pressure.
When vehicle driving high speed and
overloaded, causing tire over heat.
Reduce speed, reduce vehicle load.
When driving, air pressure not enough,

sensor data in continuous 20 minutes.
Learn binding again.
When parking vehicle for a long time, tire
pressure is normal and there is no obvious
change, and doesnt receive any sensor data
in continuous 20min.
Its normal phenomenon, after vehicle
driving, sensors start to transmit data,
warning state will be removed
automatically
Drive in same frequency interfered
area(interference strong and continuous),
such as airport, radio transmit tower etc.,
may cover sensor signal.
After leaving same frequency interfered
area, warning status will be removed
automatically.
Receiving controller wiring harness bad
connect
Detect receiving controller connector, and
connect again.
