Checking Airbag Parts after Inactivation in Accident
The airbag must be checked after any collision accident, whether it is activated or not.

Steering post must be measured for dimensions.
Check dashboard and steering post cover for crack and other damages.
Check dashboard support for deformation, bend, crack or other damages.
Check safety belts and their fixing points.

Sensor and diagnostic module (SDM)

Shift lever

Position of SDM

Warning: Operate SDM with care when maintaining. Never knock or shake SDM. Do not

connect SRS circuit before SDM is fixed onto vehicle. All SDM mounting bolts must be

tightened with care. Always make the arrow on SDM point toward forward direction of the

vehicle to ensure normal working of SRS. SDM may still work if powered before installation

onto vehicle body, but potential mistrigger of airbag and injuries may be caused.

Precautions: SDM and SDM connector may need replacement in case water enters vehicle
body due to leakage, passing through deepwater, flood or other reasons. Turn off ignition
switch and check all SDM areas including carpet. If notable new or previous water soakage is
found, clear the water and soaked parts and replace SDM and SDM connector. SRS must be
shut down before above operation. Please refer to “Disconnecting Airbag” Part in this manual.

airbag and injuries may be caused.

Air bag module of driver side

Disassembling Procedure

1. Disconnecting Battery Cathode (-)
Warning: In case engine is stopped and fuse is taken off, the SDM will provides sufficient
voltage for 1 minute to activate airbag. If airbag is still connected, do not start maintenance
operation within one minute after power supply to SDM is switched off. If airbag is
disconnected, the maintenance may be started right away without waiting for 1 minute to be
discharged. Any failure in temporary disconnection of SRS during maintenance will result in
mistrigger of airbag, personal injuries and critical SRS damages.
2. Centering

Steering

Wheel

Warning: Keep the module with the right side up when operating airbag to ensure

sufficient room for mistriggered airbag. The airbag may fly toward persons or objects in

case of insufficient spreading room and cause personal injuries or vehicle damages.

3.  Remove two airbag screws on steering wheel;
4.  Disconnect airbag from horn and airbag wire harness connector;
5.  Take off the airbag.

case of insufficient spreading room and cause personal injuries or vehicle damages.

1.  Connect horn and airbag wire harness connector to airbag socket;
2.  Install airbag module;
3.  Fix airbag module screws
4.  Tighten airbag screws with a tightening torque of 13-17Nm;
5.  Connect battery cathode (-).

Hairspring

Assembling Procedure

Warning: if the hairspring does not locate exactly, steering wheel will can not rotate
completely when turning. Restriction of turning ability may cause accident of vehicle,
incorrect hairspring location also can restrain SRS to work, make air bag dose not work when
a bump accident happened. The two instances above both can induce injury. Turning steering
wheel clockwise or counterclockwise for more than 3 cycles will damage hairspring.

1.  Adjust front wheel to just frontage
2.  Install hairspring and spiral thread
3.  Tighten the hairspring spiral thread by the tighten torque 3N.m
4.  Rotate the hairspring overhang part clockwise to lock position
5.  Rotate the hairspring overhang part three cycles counterclockwise to middle position,

then the front wheel should at the just frontage position

6.  Locate the mark on the hairspring correctly
7.  Connect harness connector to the bottom of the steering column
8.  Install steering wheel
9.  Install driver side air bag module according to “driver side air bag module” part in the

manual

10. Connect battery negative electrode (－)

Disassembling Procedure

Warning: In case engine is stopped and fuse is taken off, the SDM will provides sufficient
voltage for 1 minute to activate airbag. If airbag is still connected, do not start maintenance
operation within one minute after power supply to SDM is switched off. If airbag is
disconnected, the maintenance may be started right away without waiting for 1 minute to be
discharged. Any failure in temporary disconnection of SRS during maintenance will result in
mistrigger of airbag, personal injuries and critical SRS damages.

1.  Disconnecting Battery Cathode (-)
