2006 GREAT WALL HOVER power steering

Safety airbag-18
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.

Release the clock spring connector clip
Is the clock spring connector clip normal? Abnormal Replace the wiring harness or
connector clips

Nor mal Next step
7 Check clock spring
Remove clock spring
Take references in removal/installation of safet y airbag system as
well as clock spring
Check clock spring
Take references in the test for safety airbag system and clock spring.
Is the clock spring normal? Abnormal Replace clock spring
Take references in the
removal/installation of safety
airbag system and clock spring.
Nor mal Next step
8 Check the wiring harness between clock spring and SRS safety airbag
system electronic-control unit
Place the ignition switch in LOCK position
Release accumulator negative wire and wait for 1 minute plus
Remove PAB trim cover, glove box (passengers’ side safety airbag is
under the trim cover)
Release the passengers’ side safety airbag module connector clip
Release all SRS safety airbag system unit connector clips.
Check whether the following troubles are with the harness between
connector clips terminals of SRS safety airbag system unit and spring
clock.
Grounding
Power-supply shorting
Shutoff
Is the previous harness normal? Abnormal Replace clock spring
Take references in the
removal/installation of safety
airbag system, and clock spring

Safety airbag-18
Nor mal Present failure code
Replace SRS safety airbag system
unit
Take references in
removal/installation of SRS
safety airbag system unit in safety
airbag system.

The end of failure diagnosis
4 Check the wiring harness between passengers’ side safety airbag
module and SRS safet y airbag system electronic-control unit
Place the ignition switch in LOCK position
Release accumulator negative wire and then wait for about 1
minute plus
Remove steering pillar shell
Release clock spring connector clip
Release driver’s and passengers’ side safety airbag module
connector clips
Release all SRS safety airbag system unit connector clips
Check whether the following troubles are with the circuit of the
connector clips terminals between SRS safety airbag system
electronic-control unit and passengers’ side safety airbag
module
Grounding
Power-supply shorting
Shutoff
Is the previous circuit normal? Abnormal Replace the relative wiring
harness
