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.

2. Check whether the joint is broken and terminal is deformed
3. Check SRS-ECU bracket’s installation status
a. Check whether depression, crack or deformation is with the shroud
b. Check whether the joint is broken, terminal is deformed and wiring harness is meshed.
c. Check whether depression, crack or deformation is with the gas generator shield.
d. Make sure the direction of the arrow is straightforward
4. Check the installation status of safety airbag module.

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.

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.
