STEERING WHEEL
WARNING: SAFETY PRECAUTIONS MUST BE FOLLOWED WHEN HANDLING A DEPLOYED INFLATOR
MODULE(AIR BAG). AFTER DEPLOYMENT, THE INFLATOR MODULE(AIR BAG) SURFACE MAY CONTAIN A
SMALL AMOUNT OF SODIUM HYDROXIDE, A BY-PRODUCT OF THE DEPLOYMENT REACTION, THAT IS
IRRITATING TO
THE SKIN AND EYES. MOST OF THE POWDER ON THE INFLATOR MODULE (AIR BAG )IS
HARMLESS.
AS A PRECAUTION, WEAR GLOVES AND SAFETY GLASSES WHEN HANDLING A DEPLOYED
INFLATOR MODULE (AIR BAG ), AND WASH YOUR HANDS WITH MILD SOAP AND WATER AFTERWARDS.
WARNING: WHEN CARRYING A LIVE INFLATOR MODULE (AIR BAG ), MAKE SURE THE BAG AND TRIM
COVER
ARE POINTED AWAY FROM YOU. NEVER CARRY INFLATOR MODULE (AIR BAG )BY THE WIRES OR
CONNECTOR ON
THE UNDERSIDE OF MODULE. IN THE CASE OF AN ACCIDENTAL DEPLOYMENT, THE BAG
WILL THEN DEPLOY WITH MINIMAL CHANCE OF INJURY. WHEN PLACING A LIVE INFLATOR MODULE (AIR
BAG ) ON A BENCH OR OTHER SURFACE, ALWAYS FACE BAG AND TRIM COVER UP, AWAY FROM THE
SURFACE.NEVER
REST A STEERING COLUMN ASSEMBLY ON THE STEERING WHEEL WITH THE INFLATOR
MODULE (AIR BAG ) FACE DOWN AND COLUMN VERTICAL. THIS IS NECESSARY SO THAT A FREE SPACE
IS PROVIDED
TO ALLOW THE INFLATOR MODULE (AIR BAG) TO EXPAND IN THE UNLIKELY EVENT OF
ACCIDENTAL DEPLOYMENT. OTHERWISE, PERSONAL INJURY COULD RESULT.
NOTE: In
the event deployment has occurred, inspect coil assembly wire for any signs of scorching, melting or any
other damage due to excessive heat.
If the coil has been damaged, replace it.
REMOVAL ~-----------------------------,
1. Disable the SRS. (Refer to "Disabling the SRS "
in this section.)
2. Remove
inflator module (Air Bag) from steering
wheel by removing four bolts. Lift inflator module
(Air Bag) out of steering wheel
3. Disconnect 2-way yellow connector and remove
inflator module (Air Bag).
4. Disconnect horn lead connector
5. Remove steering wheel attachment nut.
6. Apply a setting mark across the steering wheel
and shaft so parts can be reassembled in their
original position.
7.
Move the tires to the straight ahead position
before removing the steering
wheel.and install
steering wheel puller onto steering wheel and
remove steering
wheel with J-29752.
8. Feed wiring through the wheel and remove
wheel.
CAUTION:
NEVER APPLY FORCE TO THE
STEERING WHEEL IN DIRECTION OF THE SHAFT
BY USING A HAMMER OR OTHER IMPACT TOOLS
IN AN ATTEMPT TO REMOVE THE STEERING
WHEEL. THE STEERING SHAFT IS DESIGNED AS
AN ENERGY ABSORBING UNIT.
