STEERING COLUMN
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.

STEERING WHEEL IN DIRECTION OF THE SHAFT
BY USING A HAMMER OR OTHER I~PACT TOOLS
IN AN ATTEMPT TO REMOVE THE STEERING
WHEEL. THE STEERING SHAFT IS DESIGNED AS
AN ENERGY ABSORBING UNIT.
12. Remove steering column cover.
13.
Disconne~t the wiring harness connectors
located base of steering column.
14. Remove the combination switch assembly with
SRScoil.
NOTE: SRS
coil is a part of combination switch
assembly,
which cannot be replaced individually.
Therefore, be sure not to remove the SRS coil from the
combination switch assembly.
15. Remove snap ring.
16. Remove cushion rubber.
17. Disconnect shift
lock cable(For AfT)
18. Disconnect the starter switch harness connector.
Located base of steering column.
19. Remove steering
lock cylinder assembly.
20. Apply a setting mark across the universal joint
and steering shaft to reassemble the parts
in ~
their original position. ~
21. Remove steering column assembly.
NOTE: A setting mark can be easily made if the shaft
is with draw a little by loosening the steering shaft
universal joint.
