release wiring harness
Installed the stand-by bolts on the driver’s side safety airbag module’s inside bolt and fasten a thick wire to the wheel rim to
fix it.
Connect the release wiring harness connecting with the driver’s side safety airbag module with the low part of an old tire loading
the wheel rim. ( refer to figure 9-6)
Lay three wheel-hub-free old tires on the tire fixing the driver’s side safety airbag module (Figure 9-7).

release wiring harness
Shut off the joint of driver’s side safety airbag release wiring harness somewhere far from the vehicle, and connect the joint with
the accumulator and make the safety airbag release (Figure9-8).
Caution
Release the driver’s side safety airbag module after the confirmation of nobody close to it.
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.

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.
