WARNING: All models are equipped with Air Bag Restraint System (ABRS).
See AIR BAG PRECAUTIONS before working on vehicle. Use
caution when working around steering column (air bag could
deploy).
CAUTION: When battery is disconnected, vehicle computer and memory
systems may lose memory data. Driveability problems may exist
until computer systems have completed a relearn cycle. See
COMPUTER RELEARN PROCEDURES article in GENERAL INFORMATION
before disconnecting battery.
DESCRIPTION & OPERATION
All models use collapsible steering columns with an integral
ignition switch and locking device. See Fig. 1. Optional tilt wheel is
available.
AIR BAG PRECAUTIONS
Follow precautions when working with air bag systems:
* When performing air bag repairs, disable ABRS. See AIR BAG
DISABLING.
* Use caution when handling a sensor. Never strike or jar a
sensor. All sensors or mounting bracket bolts must be
carefully torqued to ensure proper sensor operation.
* Never apply power to ABRS if a sensor is not rigidly attached
to vehicle.
* To avoid accidental air bag deployment while trouble shooting
ABRS, DO NOT use electrical test equipment, such as AC
-powered or battery-powered voltmeter, ohmmeter, etc.
* Always carry air bag module with trim cover away from body.
Always place inflatable module on workbench with trim cover
up, away from loose objects.
* DO NOT install used air bag parts from another vehicle. Use
NEW parts only. DO NOT disassemble or tamper with air bag
assembly.
* Wait at least 2 minutes after disconnecting battery before
proceeding with repairs or trouble shooting system. For a
short time after battery is disconnected, ABRS retains enough
voltage to deploy air bag.
NOTE: For additional information, see appropriate AIR BAG RESTRAINT
SYSTEMS article in ACCESSORIES & EQUIPMENT section.
AIR BAG DISABLING
Disconnect and isolate negative battery cable. Disconnect 2-
way yellow clockspring harness connector, located on top of fuse block
between clockspring and instrument panel wiring harness. Clockspring
connector may also be disconnected at Air Bag System Diagnostic Module
(ASDM).

WARNING: Wait about 2 minutes after disconnecting negative battery
cable before servicing air bag system. System reserve
capacitor maintains air bag system voltage for about 2
minutes after battery is disconnected. Servicing air bag
system before 2 minutes may cause accidental air bag
deployment and possible personal injury.
REMOVAL & INSTALLATION
WARNING: All models are equipped with Air Bag Restraint System (ABRS).
See AIR BAG PRECAUTIONS before working on vehicle. Use
caution when working around steering column (air bag could
deploy).
CAUTION: When battery is disconnected, vehicle computer and memory
systems may lose memory data. Driveability problems may exist
until computer systems have completed a relearn cycle. See
COMPUTER RELEARN PROCEDURES article in GENERAL INFORMATION
before disconnecting battery.
HORN PAD & STEERING WHEEL
Removal & Installation
1) Disable air bag system. See AIR BAG DISABLING. Ensure
steering wheel is in straight-ahead position. Remove nuts mounting air
bag module to steering wheel. Remove screws securing cruise control
switch to steering wheel (if equipped).
2) Disconnect wiring connectors. Remove air bag module and
cruise control switch assembly. Pry trim covers from back of steering
wheel and remove horn switch mounting screws. Disconnect horn wires.
Remove horn switch.
3) Remove steering wheel retaining nut. Reference mark
steering wheel and steering shaft. Using puller, remove steering
wheel. To install, reverse removal procedure. Align marks made during
removal. Tighten steering wheel retaining nut to specification.
STEERING COLUMN
Removal & Installation
1) Position front wheels straight ahead. Disconnect and
isolate negative battery cable. On column shift models, remove link
rod from bushing in shift lever. Discard bushing. On all models,
remove steering wheel using Puller (C-3428-B). See HORN PAD & STEERING\
WHEEL.
2) Remove steering column shaft-to-coupler retaining pin.
Push upper coupler shaft down into lower steering coupler. Remove dash
panel column cover. On column shift models, disconnect shift indicator
cable.
3) On all models, remove tilt lever (if equipped). Remove
upper and lower shroud. Remove lower fixed shroud. Disconnect
multifunction switch harness connector. Disconnect harness connectors
from ignition switch, key-in light, horn and cruise control (if
equipped).
4) Loosen upper support bracket nuts and allow column to drop
slightly. Remove upper fixed shroud. Disconnect wiring harness
retainers from column, and move harness to one side. Remove lower dash
panel. Remove lower steering column nuts. Remove column.
CAUTION: DO NOT reuse bushing in shift rod lever once shift rod is
removed. Always install a NEW bushing.
5) To install column, reverse removal procedure. Connect

clockspring connector. Connect negative battery cable. On column shift
models, install NEW shift lever bushing using pliers and back-up
washer to snap bushing into place. Use a multipurpose grease to aid
installation.
6) Connect gearshift cable rod to shift lever by snapping rod
into bushing with pliers.

Installation
1) Rotate flag on ignition switch to RUN position. This

allows lock cylinder to mesh with switch. With key in lock cylinder,
turn lock cylinder to RUN position so retaining pin can be depressed.
Install lock cylinder in ignition switch (aligning slot) until
retaining pin engages. Turn key to OFF or LOCK position.
2) Pull on lock cylinder to ensure retaining pin is retained
in ignition switch and cylinder will not come out. On vehicles with
automatic transmission, ensure shifter is in Park and dowel pin on
ignition switch is in Park position. Ensure ignition switch is in LOCK
position. On all models, ensure flag on ignition switch is properly
indexed in Park position. The flag operates steering lock.
3) On vehicles with automatic transmission, apply a light
coating of grease to park lock dowel and park lock slider linkage. See
Fig. 6. Slide park lock slider linkage forward completely, then back .
25" (6 mm). Apply a light coating of grease to column lock flag.
4) Carefully install ignition switch on steering column,
ensuring flag is positioned above steering wheel lock lever, dowel
pins on switch align in holes on steering column and park lock dowel
pin slides into park lock slider linkage (automatic transmission
only). See Fig. 7. Tighten mounting screws to 22-30 INCH lbs. (2.5-3.5
N.m).
5) Connect wiring connectors to ignition switch. Install
upper and lower steering column covers. Tighten screws to 17 INCH lbs.
(2 N.m). Install tilt lever (if equipped). Reconnect negative batter\
y
cable. Check for proper operation of ignition switch in all positions.
Check for proper steering wheel lock operation. Check for proper
automatic shift lock operation.

air. Inspect all parts for burrs, chips, wear, flat spots or cracks.
Replace all damaged or worn parts.
INSTALLATION
NOTE: When aligning upper ball joint nut to install cotter pin,
always tighten nut to align holes. Never loosen nut to align
holes.
1) Position steering knuckle on ball joints, and install NEW
lower ball joint nut. Tighten nut to specification. See TORQUE
SPECIFICATIONS. Install upper ball joint nut, and tighten to
