Precautions

Precaution for Technicians Using Medical Electric

Operation Prohibition

Warning

●       Parts with strong magnet is used in this vehicle.

●       Technicians using a medical electric device such as pacemaker must never perform operation on the vehicle, as magnetic field can affect the device function by approaching to such parts.

Normal charge precaution

Warning

●       If a technician uses a medical electric device such as an implantable cardiac pacemaker or an implantable cardioverter defibrillator, the possible effects on the devices must be checked with the device manufacturer before starting the charge operation.

●       As radiated electromagnetic wave generated by on board charger at normal charge operation may affect medical electric devices, a technician using a medical electric device such as implantable cardiac pacemaker or an implantable cardioverter defibrillator must not enter the vehicle compartment (including trunk) during normal charge operation.

Precaution at telematics system operation

●       If a technician uses implantable cardiac pacemaker or implantable cardioverter defibrillator (ICD), avoid the device implanted part from Communication device.

●       The electromagnetic wave of TCU might affect the function of the implantable cardiac pacemaker or the implantable cardioverter defibrillator (ICD), when using the service, etc.

●       If a technician uses other medical electric devices than implantable cardiac pacemaker or implantable cardioverter defibrillator (ICD), the electromagnetic wave of TCU might affect the function of the device. The possible effects on the devices must be checked with the device manufacturer before TCU use.

Key Part Check before Maintenance and Repair

Check the high-voltage system, and ensure the high-voltage system is powered off before starting the maintenance work, and disconnect the battery switch.

Cautions

If the timer air conditioner or timer charge is set, the high voltage system starts automatically even when the power switch is in OFF state.

Precautions for SRS "Air Bag" and "seat belt pre-tensioner

Supplemental Restraint System (SRS) "Air Bag" and "seat belt pre-tensioner" are used on the front seat belts, which can help to reduce the dangers or serious injury of the driver and the front passenger in certain type of collisions. The relevant information of safe usage of the system are included in the SRS and Safety Belt Section of the Service Manual.

Warning:

In order to prevent accidents, please follow the below points

●       Avoid the deactivation of SRS. Its failure will increase the personal injury caused by the airbag collision in the major collision accident. All the repairs must be done by the authorized dealer of JAC.

●       Improper repair, including wrong removal and installation of SRS system, will make the system unable to activate and cause personal injury. Regarding the spiral cable and airbag modules, please refer to "SRS AIR BAG".

●       Unless it is allowed in Service Manual, please do not use the electronic test equipment on the relevant circuit of SRS. The harness of SRS uses yellow or orange harness or harness connector, which can be easily recognized.

Precautions for using power tools (air or electric power) and hammers.

●       When the power switch is turned on, do not use the pneumatic or electric tools or hammer to hammer the surrounding areas of the airbag diagnostic sensor or airbag system sensors. Strong vibration may activate the sensors and unfold the air bag, which will cause serious injuries.

●       When using the pneumatic or electric tools or hammer, please switch off the power always, unplug the 12V lead-acid battery pile head, and wait at least 1 minute and then repair.

Precautions for removing 12V battery

Before removing the 12V battery, please turn the power switch to the ON position, then turn to the OFF position.

Tips

●       When the power switch is on OFF position, the automatic charging control system of the battery may start.

●       When turning the power switch from ON position to OFF position, the automatic charging control system of the battery will not start.

Common Precautions

●       Before the serving, which is not need to use the power supply: turn the power switch to LOCK position, disconnect the 12V storage battery negative terminal.

●       After disconnecting 12V storage battery negative terminal, the storage memory of radio and other control devices will be deleted.

●       Replace new oil seal. gasket. seal ring. O-ring. lock gasket. cotter pin. self-locking nut and other components.

●       Place the removed components according to the assembly-oriented position and order.

●       If necessary, use authorized binder. sealant or equivalent product.

●       In order to repair the vehicle safely and efficiently, right use of hand tools. power tools(only for removal) and special tools is necessary.

●       Before Servicing

Use suitable cover to cover the wheel fender. interior and carpet. Attention, do not use the key. fastener or the like to scratch the paintwork.

Malfunction Diagnosis

List of Malfunction Diagnosis

1.    Check the after-sales installation device that may have influence on system operation.

2.    Check easily accessible or visible system component to find out whether there is obvious damage or situation that may lead to malfunction.

3.    For all the out-of service malfunctions of loudspeaker, conduct key inspection of the positions that are easily short-to-ground in the loudspeaker circuit, which will be helpful to troubleshoot malfunctions rapidly.

4.    For the single loudspeaker out of service, the reason may be that client makes use of sound track screening function by accident, which makes single sound track out of service. This kind of malfunction does not belong to sound system malfunction, please refer to sound system instruction in user manual.
