Safety airbag-23
Driver’s and passengers’ side safety airbag module (DAB, PAB), clock spring
Caution
1. Continue the operation 60 seconds after the removal of accumulator negative. Wrap the negative with insulating
tape for insulation.
2. Safety airbag module and clock spring must not be separated nor repaired, replace the failed ones with new ones.
3. Please pay high attention when using the safety airbag module and clock spring, do not let them fall on the ground
nor fall into water or oil. Moreover, replace the depressed, crack or deformed ones with new ones.
4. After the safety airbag module is released, keep the released side up, store it somewhere flat and do not lay anything
on it.
5. The safety airbag module must not be stored in a place with the temperature above 93
.
6. The released safety airbag module must be replaced with a new one, at the same time test the clock spring, replace
it with a new one if something unusual with it.
7. Use gloves and protection glasses during operating the released safety airbag.
8. The unreleased safety airbag must be abandoned after its release.
Caution
During the removal, the wring harness connector clip must be removed before the removal of other wring harness
connector clips in order to avoid the possible improper release caused by static interferences, which is reversal to the
case of installation.
1. Removal and installation
Driver’s side safety airbag module, passengers’ side safety airbag module, clock spring.
2. Operations before removal.
a. Take out the ignition switch key after the steering wheel and front wheel in straightforward direction.
b. Remove the connections of accumulator negative
3. Driver’s side safety airbag module removal procedure
a. Screw off the bolts of two sides, as showed in Figure 8-1
b. Shut off the wiring harness connector clip
c. Remove the safety airbag module assembly
d. Remove the steering wheel
4. Passengers’ side safety airbag module removal procedure
a. Remove all the trim covers and glove boxes of instrument panel separate the PAB module’s airbag wiring harness connector
clip from the safety airbag’s PAB side one.
b. Remove M6 bolts and separate PAB module from instrument panel armed beam.
c. Remove the instrument panel itself.
d. Remove the M5bolts of two sides of four PAB modules.
5. Clock spring removal procedure
a. Remove DAB module (shut off the connecting connector clip)
b. Carefully remove the steer
c. Open the combined switch upper shield, find and shut off the bottom wring harness connector clip
d. Remove the clock spring from the steer
6. Driver’s side safety airbag module (DAB) and its installation procedure
Safety airbag-25
Figure 8.3
d. Remove the steering wheel by removing the mounting screw from the mid-position. (Shut off the horn connector)
Caution
It is difficult to separate the steer from steering column due to the over meshing between spline and steering column,
in this case, do not forcibly remove the steer but screw off the bolt on the steering column and lift up the steer instead
(the forced removal will damage the clock spring since the connection between the steer and the spring)
Caution
Diagnose the safety airbag module circuit with electric diagnostic instrument without separating it.
Let the removed driver’s side safety airbag module bottom-side up and store it at a clean and dry place.
Store the clock spring in a clean and dry place.
9. Installation operation instructions
a. The test before installation
The new safety airbag or clock spring must be tested before installation.
Caution
The safety airbag module must be abandoned after its release according to the procedure
Connect the accumulator negative
Connect the K-431 diagnostic instrument with the diagnostic interface (16 plug)
Caution
Place the ignition switch in OFF place when connect or shut off the diagnostic instrument.
Place the ignition switch in ON position
Read the diagnostic circuit, check whether the safety airbag module is in normal condition except the failure regions.
Place the ignition switch in OFF position
Remove accumulator negative and wrap it with the tape for insulation.
Caution
Continue the operation 60 seconds after the removal of accumulator negative
Install the clock spring to the steer after its involution
Clock spring’s central involution, clockwise screw the clock spring to the end, then turn it for 3 circles anticlockwise and make

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.

Caution
Continue the operation after the confirmation of nobody is in or next to the vehicle.
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.

2. Release outside the vehicle
Caution
Release the safety airbag somewhere open and plain as well as 6m plus from the obstacles and people
When release the safety airbag outdoors, try to avoid the strong wind and ignite windward in the breeze.
a. Remove the accumulator negative and positive and remove the accumulator.
Caution
Continue the operation 60 seconds after the removal of the accumulator.
b. Release the safety airbag module according to following procedure
driver’s side safety airbag module
remove the driver’s side safety airbag module off the vehicle.
Caution
The two ends of the terminal will short automatically without the joint connection of driver’s safety airbag module,
therefore the possible improper release caused by static interference can be avoided; if it improperly releases, keep the
released side up and store it somewhere plain, do not lay anything on it.
Prepare 2 6m plus release wiring harnesses and mutually connect the other ends(short-circuit) of them to avoid the possible
improper release caused by static interference.( refer to figure 9-4)
Touch the vehicle with your hands to eliminate the static electricity.
Caution
Strictly execute the previous procedure for it can prevent the possible incorrect release caused by the static interference
from happening.
Shut off the driver’s side safety airbag module wiring harness and connect it with two release wiring harnesses( refer to figure
