Safety airbag module abandoning instruction
Carry out the operation according to the following procedure to abandon a safety airbag module or a vehicle with the SRS
safety airbag. First of all, release the safety airbag.
Unreleased safety airbag module abandoning
Caution
First release the SRS safety airbag when abdbdon it.
Release the safety airbag outside the vehicle to replace the safety airbag module.
Conduct the operation somewhere next to a smoke tester due to the smoke during the safety airbag’s release.
Tell the people to cover their ears and try to conduct the operation somewhere far away from the residential area due
to the big noise during the safety airbag’s release.
Remove the accumulator positive and negative and remove the accumulator off the vehicle.
Caution
Continue the operation 60 seconds after the removal of accumulator positive and negative.
Release the safety airbag module according to the following procedure.
1. Driver’s side safety airbag module
a. Remove the blocking lever
b. Remove the clock spring 2# joint and instrument panel wiring harness joint (yellow)(figure 8.6)
Caution
The clock spring joint will short automatically after the removal of clock spring from the instrument wiring harness,
which can prevent any possible major accident caused by the incorrect release of driver’s side safety airbag module duo
to the static interference from happening.
c. Connect the SRS safety airbag translation wring harness with 2 6m plus release wiring harnesses, wrap the joint part with
insulating tape for insulation.

releases wring harness. Mutually connect (short) the other end of release wring harness to avoid the possible incorrect release caused by the static
interference.
d. At the clock spring’s 2# joint, tract the translation wiring harness out of the vehicle with the release wiring harness (Figure 9.2)
e. Close all the windows and doors and wear the guard to reduce the noises.
Caution
The guard should be worn because the glass with cracks is very fragile.
f. Shut off the joint of driver’s side safety airbag release wiring harness somewhere far from the vehicle, and connects the joint
with the accumulator and makes the safety airbag release.

Its gas generator is quite hot after the driver’s side safety airbag’s release, it can be used after its cooling down for more
than 30 minutes.
Contact with the local service station of the Great Wall Auto Stock Corporation if the driver’s side safety airbag module
cannot be released.
g. Abandon the released driver’s side safety airbag module according to the instructions.

Impact-vehicle diagnosis
Test SRS-ECU diagnostic signals
1. Connect the (X-431 diagnostic test’s) diagnostic joint
2. Read the diagnostic results with X-431 diagnostic tester
Repairing procedure
1.When safety airbag is released.
The following parts should be replaced with new ones
a. Passengers’ side safety airbag module
b. SRS-ECU
c. Driver’s side safety airbag module
2 Check the following parts; replace them with new ones providing something wrong with them.
a. Clock spring
b. Steering-wheel, steering column, bottom steering shaft module
3.Driver’s side safety airbag module’s installation status towards the steering wheel.
a. Check whether abnormal knocking is with the steering wheel, its activity is in good condition and its clearance is normal.
b. Check whether the wiring harness joint is broken and its terminal is deformed.
Caution: Due to the impact, the diagnostic instrument cannot communicate with SRS-ECU when accumulator is lack of
power, in this case, check and maintain the instrument panel wiring harness or utilize the extension power supply.
