Supplemental restraint system--Remove malfunction
Diagnostic procedure
When starting to check, firstly, use special diagnostic tool and ECU to make diagnostic communication to
find the reason of malfunction, if communication could not implement, make following inspection:
(1) Check the battery
a. Measure the voltage of battery
b. Is the voltage higher than 9V?
Yes: make next operation,
No: Power supply of battery is lack, check the charging/discharging system, then make step 5.
(2) Check the conduction of wiring harness between ECU and combination meter.
a. Set ignition switch at LOCK position,
b. Cut off cathode of battery,
c. Open the defending board of central channel,
d. Disconnect the connector of instrument package ,
e. Connect the cathode of battery,
f. Set ignition switch at ON position,
g. Check whether the terminal voltage of corresponding connector of instrument is 12V (connecting
wire of power supply and instrument)
Yes: make next step,
No: check the circuit part, then make step 5 after repairing it.
h. Set ignition switch at LOCK position,
i. Check whether the corresponding terminal of instrument connector conducts with corresponding
terminal of diagnostic interface (diagnose two ends of K wire),
Yes: make next step,
No: repair or change the wiring harness, then make step 5.
j. Guarantee cathode of battery is cut off and keep this state for one minutes at least, cut off connec-
tor of ECU.
k . Disconnect the plug of instrument package,
l. Check whether it conducts between ECU plug voltage, K wire, airbag indicating light terminal and
plug of instrument package ?
Yes: make next operation,
No: change the wiring harness, then make the step 5.
m. Disassemble the ECU to check whether the terminal is good, and the short circuit stick is broken.
Yes: change the ECU,
No: connect the ECU connector again, then make next operation.

Diagnostic procedure
(1) Check the battery
zIs the voltage higher than 9V?
Yes: make next operation,
No: The voltage of battery is too low, check the charging/discharging system.
zRefer to chapter 1, Inspection of battery, charging system
(2) Check the wiring harness between battery and safety boox.
zDisassemble fuse panel to set ignition switch at ON position without loosening connector.
zMeasure 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.
