DISARMING
1. Turn the steering wheel to align the w heels in the straight-ahead position.
2. Turn the ignition switch to the LOCK position.
3. Remove the SIR air bag fuse from the fuse block.
4. Remove the left side trim panel and disconnect the yellow 2-way SIR
harness wire connector at the bas e of the steering column.
To enable system: 5. Turn the ignition switch to the LOCK position.
6. Reconnect the yello w 2-way connector at the base of the steering
column.
7. Reinstall the SIR fuse and the left side trim panel.
8. Turn the ignition switch to the RUN position.
9. Verify the SIR indicator light flashes 7-9 times, if not as specified, inspect
system for malfunction or c ontact the manufacturer.
For more details on the SIR system - including disarming instructions for
passenger bags - please refer to Chassis Electrical in this repair guide.
SUPPLEMENTAL INFLATABLE REST RAINT (SIR) COIL ASSEMBLY
After performing repairs on the inter nals of the steering column the coil
assembly must be centered in order to avoid damaging the coil or accidental
deployment of the air bag. There are 2 different styles of coils, one rotates
clockwise and the other rotates counterclockwise.
ADJUSTMENT (CENTERING THE COIL) 1. With the system properly disarmed, hold the coil assembly with the clear
bottom up to see the coil ribbon.
2. While holding the coil assembly, depr ess the lock spring and rotate the
hub in the direction of the arrow until it stops. The coil should now be
wound up snug against the center hub.
3. Rotate the coil assembly in the opposite direction approximately 2
1/2
turns and release the lock spring between the locking tabs in front of the
arrow.
4. Install the coil assembly onto the steering shaft.
STEERING WHEEL
WARNING - Before attempting any repairs involving the steering wheel or
disassembly of it, ensure that the Supple mental Inflatable Restraint (Air Bag)
system is properly disarmed.
REMOVAL & INSTALLATION
If the vehicle is equipped with a SIR (A ir Bag) system, ensure that the proper
disarming procedure is followed.

2. Loosen the screws and lo
cknuts from the back of the steering wheel
using a suitable Torx® driver or equi valent, until the inflator module can
be released from the steering wheel. Remove the inflator module from
the steering wheel.
CAUTION - When carrying a live inflator modul e, ensure the bag and trim cover
are pointed away from the body. In ca se of an accidental deployment, the bag
will then deploy with minima l chance of injury. When placing a live inflator
module on a bench or other surface, a lways place the bag and trim cover up,
away from the surface. This is necessa ry so a free space is provided to allow
the air bag to expand in the unlikely event of accidental deployment. Otherwise,
personal injury may result. Also, never carry the inflator module by the wires or
connector on the underside of the module.
4. Disconnect the coil assembly connec tor and CPA clip from the inflator
module terminal.
5. Remove the steering wheel locking nut.
6. Using a suitable pulle r, remove the steering wheel and disconnect the
horn contact. When attaching the steer ing wheel puller, use care to
prevent threading the side screws into the coil assembly and damaging
the coil assembly.
To install: 7. Route the coil assembly connec tor through the steering wheel.
8. Connect the horn contact and install the steering wheel. When installing
the steering wheel, ali gn the block tooth on the steering wheel with the
block tooth on the steering shaft within 1 female serration.
9. Install the steering wheel locking nu t. Tighten the nut to 31 ft. lbs. (42
Nm).
10. Connect the coil assembly connector and CPA clip to the inflator module
terminal.
11. Install the inflator module. Ensu re the wiring is not exposed or trapped
between the inflator modul e and the steering wheel. Tighten the inflator
module screws to 25 inch lbs. (2.8 Nm).
12. Connect the negative battery cable.
13. Enable the SIR system as follows: a. Connect the yellow 2-way SIR harness connector to base of the steering column and CPA.
b. Install the left sound insulator.
c. Install the SIR fuse in the fuse block.
d. Turn the ignition switch to the RUN position and verify that the
inflatable restraint indicator fl ashes 7-9 times and then turns OFF.
If the indicator does not respond as stated, a problem within the
SIR system is indicated.

IGNITION SWITCH
WARNING
- Before attempting any repairs involving the steering wheel or
disassembly of it, ensure that the Supple mental Inflatable Restraint (Air Bag)
system is properly disarmed.
REPLACEMENT
Fig. 1: Ignition switch
The switch is located inside the channe l section of the brake pedal support and
is completely inaccessible without firs t lowering the steering column. The switch
is actuated by a rod and rack assembly . A gear on the end of the lock cylinder
engages the toothed upper end of the rod.
1. Lower the steering column; be sure to properly support it.
2. Put the switch in the Off-Unlocked position. The Off-Unlocked position is
two detents from the top.
3. Remove the two switch screws and remove the switch assembly.
To install: 4. Before installing, place the new switch in the Off-Unlocked position.
Make sure the lock cylinder and actuating rod are in the Off-Unlocked
(second detent from th e top) position.
5. Install the activating rod into the switch and assemble the switch on the
column. Tighten the mount ing screws. Use only the specified screws
since overlength screws could impair the collapsibility of the column.
6. Reinstall the steering column.

ng the steering column support bracket
to the instrument panel.
9. Disconnect the park lock cable from the ignition switch inhibitor, if
equipped with automatic transmission.
10. Remove the steering column from the vehicle.
To install:
If a replacement steering column is bein g installed, do not remove the anti-
rotation pin until after the steering co lumn has been connected to the steering
gear. Removing the anti-rotation pin before the steering column is connected to
the steering gear may dam age the SIR coil assembly.
11. Position the steering column in the vehicle.
12. Connect the park lock cable to the ig nition switch inhibitor on vehicles
with automatic transmission.
13. Install the capsule nuts attaching the steering column support bracket to
the instrument panel and tighten to 20 ft. lbs. (27 Nm).
14. Install the nut and bolt to the upper intermediate shaft coupling attaching
the upper intermediate shaft to the steer ing column. Tighten the nut to 44
ft. lbs. (60 Nm).
15. Install the bolts attaching the toe pl ate to the cowl and tighten to 58 inch
lbs. (6.5 Nm).
16. Connect the electrical connectors.
17. Remove the anti-rotation pin if a se rvice replacement steering column is
being installed.
18. Install the knee bolster and bracket, if equipped.
19. Install the sound insulator panel.
If SIR coil has become uncentered by turni ng of the steering wheel without the
column connected to the st eering gear, follow the proper adjustment procedure
for the SIR coil assembly before proceeding.
20. Install the steering wheel.
21. Connect the negative battery cable.
22. Enable the SIR system as follows: a. Connect the yellow 2-way SIR harness connector to the base of
the steering column and CPA clip and install the SIR fuse.
b. Install the left sound insulator.
c. Turn the ignition switch to the RUN position and verify that the
inflatable restraint indicator fl ashes 7-9 times and then turns OFF.
If the indicator does not respond as stated, a problem within the
SIR system is indicated.
