Diagnostic procedure
(1) Check the battery
Is the voltage higher than 9V?
Yes: make next operation,
No: The voltage of battery is too low, check the charging/discharging system.
Refer to chapter 1, Inspection of battery, charging system
(2) Check the wiring harness between battery and safety boox.
Disassemble fuse panel to set ignition switch at ON position without loosening connector.
Measure whether the voltage of related two pins of fuse panel is more than 9V?
Yes: make next step
No: check and repair the wiring harness.
(3) Check the wiring harness between fuse panel and the connector of safety airbag system unit.
Warning:
If the treatment is wrong, safety airbag assembly might be triggered to unfold to make heavy
human hurt, so, before the treatment, it is necessary to read repairing warnings carefully.
Refer to repairing warning of safety airbag system.
a. Set ignition switch at LOCK position,
b. Loosen the cathode cable of battery and keep this state for one minute at least,
c. Disassemble the shell body of steering column,
d. Loosen the connector of helix cable,
e. Disassemble glove box (with safety airbag assembly at the side of passenger),
f. Loosen the connector of safety airbag assembly at the side of passenger,
g. Disassemble left inner trim board,
h. Loosen the connectors of all safety airbag system units,
i. Assemble cathode cable of battery, and set the ignition switch at ON position, then measure
whether the voltage of safety airbag system unit and grounding connector pin is more than 9V?
Yes: make next step,
No: change the wiring harness.
j. Set the ignition switch at LOCK position,
Loosen the cathode cable of battery and keep this for one minute at least.
k. Disassemble left inner trim board,
l. Cut off the conversion connector of safety airbag system unit,
m. Assemble cathode cable of battery, and set the ignition switch at ON position, then measure
whether the voltage of safety airbag system unit and grounding connector pin is more than 9V?
Yes: malfunction diagnosis ends,
No: change the wiring harness.
