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
the involution with the marked sites

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.
safety airbag system failure alarm lamp
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.

Caution
Replace the safety airbag with depression, crack or deformation with a new one. Its old parts must be abandoned after
its release.

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
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.
