DESCRIPTION AND OPERATION
STEERING COLUMN
This vehicle is equipped with both tilt and non-tilt
steering columns. Both steering columns have been
designed to be serviced only as complete assemblies
if an internal component is found to be defective (Fig.
1). The shaft, bearings and upper coupling are all
serviced with the column.
The replaceable components on the steering col-
umn assembly are:
²the key cylinder
²the ignition switch
²the multi-function switch
²the clockspring²the trim shrouds
²the steering wheel
²the driver airbag module
These components can be serviced without removal
of the steering column from the vehicle. Refer to the
appropriate group and section of this service manual
for servicing these components separately.
STEERING COLUMN LOWER COUPLING
This vehicle uses a corrugated design lower cou-
pling to connect the steering column to the steering
gear (Fig. 2).
This coupling has a hollow corrugated tube that
allows the coupling to bend rather than collapse
when a vehicle is involved in a collision.

REMOVAL
(1) Disconnect the negative (-) cable from the bat-
tery and isolate the cable.
(2) Before beginning removal of the steering col-
umn, be sure the front wheels of vehicle are in the
STRAIGHT-AHEAD position.
(3) Remove the screw securing the left end of the
top cover to the instrument panel. It is located just
above the left instrument panel end cap.
(4) Starting on the driver's end, push upward on
the instrument panel top cover, disengaging its
retainer clips along the face of the instrument panel.
Disengage just enough clips to allow access to the
upper ends of the instrument cluster bezel.
(5) Disengage the clips along the outer edge of the
instrument cluster bezel and remove the bezel from
the vehicle.
(6) Remove the two screws along the bottom of the
steering column cover that mounts below the steering
column on the instrument panel. Disengage the clips
on the upper end of the steering column cover and
remove the cover by pulling it straight away from the
instrument panel.
(7) If the vehicle is equipped with speed control,
remove the speed control switches from the steering
wheel (Fig. 6).WARNING: WHEN AN UNDEPLOYED AIRBAG MOD-
ULE IS TO BE REMOVED FROM THE STEERING
WHEEL, FIRST DISCONNECT THE BATTERY
GROUND CABLE AND ISOLATE IT. ALLOW THE
SYSTEM CAPACITOR TO DISCHARGE FOR A MINI-
MUM OF TWO MINUTES, THEN BEGIN THE AIRBAG
REMOVAL.
(8) If the vehicle is not equipped with speed con-
trol, remove the airbag mounting screw trim caps
from the steering wheel rear cover (Fig. 7). There is
one on each side of the steering wheel.
(9) Remove the two mounting screws, one on each
side of steering wheel, attaching the airbag module
to the steering wheel (Fig. 6).
(10) Lay the airbag module back away from the
center of the steering wheel (Fig. 6). Disconnect the
clockspring and horn switch electrical connectors
from the back of the airbag module. Remove the air-
bag module from the steering wheel.
(11) Holding the steering wheel firmly in place,
remove the steering wheel retaining nut from the
steering column shaft in the center of the steering
wheel. If equipped, remove the damper weight from
the steering wheel.

REMOVAL AND INSTALLATION (Continued)

bolt nut to a torque of 28 N´m (250 in. lbs.). Install
the pinch bolt retainer pin.
(11) Install the upper and lower steering column
shrouds onto the steering column (Fig. 9). Snap the
two shrouds together and then install and tighten
the two screws securing the shrouds to the column.
(12) Install the steering column cover that mounts
below the steering column on the instrument panel
by first aligning the retainer clips and snapping the
cover into place. Install the two screws along the bot-
tom of the steering column cover.
(13) Align the clips along the outer edge of the
instrument cluster bezel with the mounting holes in
the instrument panel and install the bezel.
(14) Align the clips on the bottom of the instru-
ment panel top cover with the mounting holes in the
instrument panel and install the top cover by push-
ing it down into place.
(15) Install the screw securing the left end of the
top cover to the instrument panel.
CAUTION: If there is any question as to whether
the clockspring is in the centered position, the
clock spring needs to be recentered before install-
ing the steering wheel. If the clockspring is not cen-
tered, it may be overextended, causing the
clockspring to become inoperative.
(16) Center the clockspring using the following
procedure:
²Using your fingers, rotate the clockspring rotor
in the CLOCKWISE DIRECTION to the end of the
travel. Do not apply excessive torque.
²From the end of travel, rotate the rotor two full
turns and an additional half turn in the counter-
clockwise direction. (The wires should end up at the
bottom of the clockspring).
CAUTION: Do not install the steering wheel onto
the shaft of the steering column by driving it onto
the shaft.
(17) Feed the clockspring wiring leads through the
hole in the steering wheel (Fig. 6). Align the steering
wheel's wide mounting spline with the steering col-
umn shaft missing spline area and push the wheel
onto the shaft. Make sure the clockspring squares up
with the back of the wheel and does not bind.
(18) Install the steering wheel retaining nut and
tighten it until the steering wheel is fully installed
on shaft. Tighten the steering wheel retaining nut to
a torque of 61 N´m (45 ft. lbs.).
(19) Connect the clockspring electrical leads to the
speed control switches and reinstall the switches on
the steering wheel (Fig. 6).
(20) Install the airbag electrical lead from the
clockspring into the connector on the back of the air-bag module (Fig. 6). Be sure electrical connector from
clockspring is securely latched into airbag module
connector.
(21) Connect the horn switch electrical lead to the
connector on the back of the airbag module (Fig. 6).
CAUTION: The fasteners originally used for the air-
bag components are specifically designed for the
airbag system. They must never be replaced with
any substitutes. Anytime a new fastener is needed,
replace it with only the correct fastener listed in the
parts book.
(22) Install the airbag module into the center of
the steering wheel. Align the airbag module mount-
ing holes with the bolt holes in steering wheel (Fig.
6). Install only the two original or identical replace-
ment airbag module mounting screws. Tighten the
two air bag module attaching bolts to a torque of 10
N´m (90 in. lbs.).
(23) Install the airbag mounting screw trim caps
on the steering wheel rear cover (Fig. 7). One belongs
on each side of the steering wheel.
NOTE: When reconnecting the battery on a vehicle
that has had the airbag module removed, the fol-
lowing procedure should be used.
(24) Reconnect the ground cable to the negative
post of the battery in the following manor:
²Connect a scan tool (DRBIIIt) to the data link
diagnostic connector located below the steering col-
umn.
²Turn the ignition key to the ON position. Exit
the vehicle with the scan tool leaving the scan tool
harness plugged in.
²Ensuring that there are no occupants in the
vehicle, connect the ground (-) cable to the negative
post of the battery.
²Using the scan tool, read and record any fault
codes. Refer to the DRIVER AND PASSENGER AIR-
BAG SYSTEM diagnostic manual if any faults are
found.
²Erase any stored faults if there are no active
fault codes. If a problem exists, the fault code will
not erase.
²Reach around the back of the steering wheel (in
front of the instrument cluster) and turn the ignition
key to OFF, then back ON while observing the
instrument cluster airbag lamp. It should go on for
six to eight seconds, then go out. This will indicate
that the airbag system is functioning normally. If air-
bag warning lamp fails to light, blinks on and off, or
goes on and stays on, there is an airbag system mal-
function. Refer to the BODY DIAGNOSTIC PROCE-
DURES manual to diagnose the system malfunction.
