1. Extinguishments of safety airbag system alarm lamp
Troubleshooting
Extinguishments or normal-light of alarm lamp
NO . Troubleshooting item Description
1 T he warning la mp of safety a irbag
system is not displayed. Safety airbag system warns circuit failure
2 T he warning la mp of safety a irbag
system is light normally. Safety airbag system warns circuit failure or external
failure.

1 Extinguishments of safety airbag system alarm lamp
Test status Safety airbag system warns circuit failure.
Possible causes No voltage (fuse shutoff)
Combined instrument failure
Failure of wiring harness between instrument cluster and ECU unit

Diagnostic procedure
When first carry out failure test, joggle the wiring harness and plug to test whether there is periodical bad contact in the circuit, if
it so, please confirm whether the plug, terminal and wiring harness well connected and in good condition. If it is not any of previous
cases, operate according to the following steps.
Procedure Te s t Operation
Ye s Place the ignition switch in LOCK
position followed by next step
1 Test other wiring harness and instrument cluster
indicator lamp
·place the ignition switch in ON position
·light other alarm and indicator lamps No Test the instrument cluster power-supply
system and grounding s ystem (fuse), then
go to step 5.
Yes Next step
2 Bulb test
Warning:
Incorrect handling with the safety airbag system
units will cause the safety airbag’s improper
release and pretension of safety belt, which will
lead to serene accidents. Please read safety airbag
service warning before handling the safety airbag
units.
·Place the ignition switch in LOCK position。
·shut off accumulator negative line and keep the
status for at least 60 seconds.
·Remove the combined instrument.
Test the connection between the two
corresponding stitches of safety airbag alarm lamp No

2 Normal-light of safety airbag system alarm lamp
Test status Normal-light of safety airbag system alarm lamp
Possible causes Insufficient battery voltage
ECU internal failure
Combined instrument safety airbag alarm lamp failure
ECU plug misconnects
Combined instrument plug bad-contact
ECU power-supply fuse shutoff or bad contact
Misconnection of ECU plug terminal
Bad contact between ECU plug terminal and grounding wiring
harness.
Driver ’s or passengers’ side safety airbag circuit failure.

Procedure Te s t Operation
Yes Next procedure.
3 Test the wiring harness connection between ECU
unit and instrument cluster.
·Place the ignition switch in LOCK position。
·shut off accumulator negative line
·shut off the instrument cluster plug
·test the connection b etween alarm lamp circuit
and its relative circuits No Replace the wiring harness and get into
step 5

Safety airbag-26
Do the troubleshooting if the alarm lamp re-illuminates after its extinguishments following the 6-second-flashing (or it keeps
illuminating from the very beginning)
10. Test
a. Driver’s side airbag module test (Figure8-3)
Check the following items and replace the corresponding safety airbag module part with anything abnormal with a new one.
Abandon the safety airbag’s old parts after its release according to the instructed procedure.
Caution
Do not jam the clock spring wiring harness during the steering wheel and safety airbag module assembly installation.
After the installation, rotate the steering wheel to left and right positions as enough as possible to confirm whether something
abnormal is with it.
d. Post-installation test.
lightly rotate the steering wheel to the left and right to confirm whether something abnormal and noises will arise.(Driver’s side
safety airbag module, clock spring)
Place the ignition switch in ON place.
SRS alarm lamp flashes in 6 seconds and then extinguishes.
Caution
If without the clock spring central involution, the steering wheel will not be able to rotate at midway, or the clock spring
circuit will be damaged so that jeopardize SRS safety airbag’s normal activities.
The spacer must be removed after replacing a clock spring with a new one, otherwise it will damage the clock spring.
c. Steering wheel and safety airbag module assembly installation.
Install the steering wheel and safety airbag module assembly after clock spring’s central involution.

Caution
The safety airbag module (squib) circuit resistance can even not be tested by the designated tester.
When testing the resistance with an experimental instrument, sometimes the improper release will be caused by the
static interference because of the current in explosion pipe and cause some major damaging accidents.
Whether depression, crack or deformation is with the shroud.
Whether the joint is broken and the terminal is deformed.
Whether depression, crack or deformation is with the gas generator shield.
Safety airbag module. Installation status.
Caution
Replace the safety airbag with depression, crack or deformation with a new one. Its old parts must be abandoned after
its release.
