SERVICE. FAILURE TO TAKE THE PROPER PRE-
CAUTIONS COULD RESULT IN ACCIDENTAL AIR-
BAG DEPLOYMENT AND POSSIBLE PERSONAL
INJURY.
(1) Disconnect the negative battery cable.
(2) Remove the knee blocker from the instrument
panel. See Knee Blocker in Group 8E - Instrument
Panel Systems for the procedures.
(3) Insert the key in the ignition lock cylinder and
turn the ignition switch to the On position.
(4) Insert
a
small
screwdriver
or
pin
punch
through the access hole in the lower steering column
shroud and depress the ignition lock cylinder retain-
ing tumbler (Fig. 2).
(5) While holding the retaining tumbler depressed,
pull the ignition lock cylinder and key out of the igni-
tion lock housing.
(6) Remove the three screws that secure the lower
steering column shroud to the upper shroud.
(7) If the vehicle is so equipped, move the tilt
steering column to the fully lowered position.
(8) If the vehicle is so equipped, loosen the two
nuts that secure the non-tilt steering column upper
mounting bracket to the dash panel steering column
support bracket studs. Lower the column far enough
to remove the upper steering column shroud.
(9) Remove both the upper and lower shrouds from
the steering column.
(10) Disengage the steering column wire harness
retainer from the tab on the top of the Sentry Key
Immobilizer Module (SKIM) mounting bracket (Fig.
3).
(11) Unplug the wire harness connector from the
SKIM receptacle.
(12) The SKIM mounting bracket features a clip
formation that secures the SKIM to the inboard
lower flange of the steering column jacket. Pull
downward on the connector end of the SKIM mount-
ing bracket to release this clip from the steering col-
umn jacket.
(13) Rotate the SKIM and its mounting bracket
downwards and then to the side away from the steer-
ing column to slide the SKIM antenna ring from
around the ignition switch lock cylinder housing.

(14) Remove the SKIM from the vehicle.
(15) Reverse the removal procedures to install.
Tighten the non-tilt steering column mounting nuts
to 22 N·m (200 in. lbs.) and the steering column
shroud mounting screws to 2 N·m (18 in. lbs.).

GENERAL INFORMATION
INTRODUCTION
Six-way power seats are an available factory-in-
stalled option for Left-Hand Drive (LHD) versions of
this model. Refer to 8W-63 - Power Seat in Group 8W
- Wiring Diagrams for complete circuit descriptions
and diagrams.
NOTE: This group covers both Left-Hand Drive
(LHD) and Right-Hand Drive (RHD) versions of this
model. Whenever required and feasible, the RHD
versions of affected vehicle components have been
constructed as mirror-image of the LHD versions.
While most of the illustrations used in this group
represent only the LHD version, the diagnostic and
service
procedures
outlined
can
generally
be
applied to either version. Exceptions to this rule
have been clearly identified as LHD or RHD, if a
special illustration or procedure is required.
POWER SEAT SYSTEM
The power seat system option allows the front
seating positions to be electrically adjusted for opti-
mum control and comfort using the power seat
switches located on the outboard seat cushion side
shield. The power seat system allows the seating
position to be adjusted forward, rearward, front up,
front down, rear up, or rear down. The power seat
system receives battery current through a fuse in the
Power Distribution Center and a circuit breaker in
the junction block, regardless of the ignition switch
position.
The power seat system includes the power seat
adjuster and motors unit, the power seat switch, and
the circuit breaker. Following are general descrip-
tions of the major components in the power seat sys-
tem. Refer to the owner’s manual in the vehicle glove
box for more information on the features, use and
operation of the power seat system.
DESCRIPTION AND OPERATION
POWER SEAT SWITCH
The power seat can be adjusted in six different
ways using the power seat switch. The switch is
located on the lower outboard side of the seat cushion
on the seat cushion side shield. Refer to the owner’s
manual for more information on the power seat
switch functions and the seat adjusting procedures.
The individual switches in the power seat switch
unit cannot be repaired. If one switch is damaged or
faulty, the entire power seat switch unit must be
replaced.
POWER SEAT ADJUSTER AND MOTORS
There are three reversible motors that operate the
power seat adjuster. The motors are connected to
worm-drive gearboxes that move the seat adjuster
through a combination of screw-type drive units.
The front and rear of a seat are operated by differ-
ent motors. They can be raised or lowered indepen-
dently of each other. When the center seat switch is
pushed to the Up or Down position, both the front
and rear motors operate in unison, moving the entire
seat up or down. The forward-rearward motor is
operated by pushing the center seat switch to the
Forward or Rearward position.
When a switch is actuated, a battery feed and a
ground path are applied through the switch contacts
to the motor(s). The motor(s) and drives operate to
move the seat in the selected direction until the
switch is released, or until the travel limit of the
power seat adjuster is reached. When the switch is
