DESCRIPTION
The lock cylinder is inserted in the end of the
housing opposite the ignition switch.
OPERATION
The ignition key rotates the cylinder to 5 different
detents (Fig. 30) :
²Accessory
²Off (lock)
²Unlock
²On/Run
²Start
REMOVAL
(1) Disconnect negative cable from battery.
(2) Remove steering column cover retaining
screws.

position (retaining tab on lock cylinder can be
depressed).(2) The shaft at the end of the lock cylinder aligns
with the socket in the end of the housing. To align
the socket with the lock cylinder, ensure the socket is
in the Run position (Fig. 31).
(3) Align the lock cylinder with the grooves in the
housing. Slide the lock cylinder into the housing
until the tab sticks through the opening in the hous-
ing.

(14) Remove the bolts attaching the cradle cross-
member reinforcement to the front suspension cradle
crossmember (Fig. 6). Remove the 2 bolts fastening
the reinforcement and rear of cradle crossmember to
the body of the vehicle. Remove lower rear bushings,
then the reinforcement.
(15) If the vehicle is equipped with All-Wheel-
Drive, remove the power transfer unit as necessary
(Refer to 21 - TRANSMISSION/TRANSAXLE/
POWER TRANSFER UNIT).
(16) Remove tube nuts and power steering pres-
sure and return hoses from the power steering gear
(Fig. 7).
(17) Remove the 3 bolts and nuts mounting the
steering gear to the front suspension cradle (Fig. 8).NOTE: The next step must be done to allow the
removal of the steering gear from the front suspen-
sion cradle. The steering gear can not be removed
from the vehicle with the intermediate coupler
attached to the steering gear.
(18) Lower steering gear from suspension cradle
enough to allow access to the intermediate coupler
roll pin (Fig. 9). Install Remover/Installer Special
Tool 6831A through the center of the roll pin, secur-
ing with the knurled nut (Fig. 9). Hold threaded rod
stationary while turning nut, this will pull the roll
pin out of the intermediate coupler.
(19) Separate the coupler from the shaft of the
steering gear.
(20) Remove the power steering gear from the
vehicle.
REMOVAL - RHD GEAR
(1) Remove cap from power steering fluid reser-
voir.
(2) Using a siphon pump, remove as much fluid as
possible from the power steering fluid reservoir.
CAUTION: Locking the steering column in the
straight-ahead position will prevent the clockspring
from being accidentally over-extended when the
steering column is disconnected from the interme-
diate steering coupler.
(3) Position the steering wheel in the STRAIGHT-
AHEAD position. Lock the steering wheel in place
using a steering wheel holding tool.
(4) With the ignition key in the locked position
turn the steering wheel to the left until the steering
wheel is in the locked position.
(5) With the vehicle on the ground, disconnect the
steering column shaft coupler from the steering gear
intermediate coupler (Fig. 2).
(6) Raise vehicle. (Refer to LUBRICATION &
MAINTENANCE/HOISTING - STANDARD PROCE-
DURE)
(7) Remove front wheel and tire assemblies.
(8) If power steering cooler equipped, remove a
hose at power steering cooler and allow fluid to
drain.
(9) Remove 2 bolts attaching power steering cooler
to cradle crossmember reinforcement (Fig. 3).
(10) On both sides of vehicle, remove nut attaching
outer tie rod end to steering knuckle (Fig. 4).
Remove nut by holding tie rod end stud with a
socket while loosening and removing nut with
wrench.

OPERATION
The Brake/Transmission Shift Interlock (BTSI)
Solenoid prevents the transmission shift lever from
being moved out of PARK (P) unless the brake pedal
is applied. The BTSI solenoid is hardwired to and
controlled by the Intelligent Power Module (IPM).
Battery voltage is applied to one side of the solenoid
with the ignition key is in either the OFF, ON/RUN,
or START positions (Fig. 269). The ground side of the
solenoid is controlled by a driver within the IPM. It
relies on voltage supplied from the stop lamp switch
to the stop lamp sense circuit within the IPM to tell
when the brake pedal is depressed. When the brake
pedal is depressed, the ground circuit opens, de-ener-
gizing the solenoid. When the brake pedal is
released, the ground circuit is closed, energizing the
solenoid.
When the ignition key is in either the OFF,
ON/RUN, or START positions, the BTSI solenoid is
energized, and the solenoid plunger hook pulls the
shift lever pawl into position, prohibiting the shift
lever from moving out of PARK (P) (Fig. 270). When
the brake pedal is depressed, the ground circuit
opens, de-energizing the solenoid. This moves the
gearshift lever pawl out of the way (Fig. 271), allow-
ing the shift lever to be moved into any gear position.

SHIFT INTERLOCK SOLENOID (Continued)
A conventional mechanical interlock system is also
used. This system manually prohibits shifter move-
ment when the ignition switch is in the LOCK or
ACC positions. Solenoid operation is not required in
these key positions.
For intended BTSI system operation, refer to the
following chart:
ACTION EXPECTED RESPONSE
1. Turn key to the9OFF9
position.1. Shifter CAN be shifted
out of park with brake
pedal applied.
2. Turn key to the
9ON/RUN9position.2. Shifter CANNOT be
shifted out of park.
3. Turn key to the
9ON/RUN9position and
depress the brake pedal.3. Shifter CAN be shifted
out of park.
4. Leave shifter in any
gear and try to return key
to the9LOCK9or9ACC9
position.4. Key cannot be
returned to the9LOCK9or
9ACC9position.
5. Return shifter to

the key.5. Key can be removed
(after returning to9LOCK9

6. With the key removed,
try to shift out of9PARK9.6. Shifter cannot be
shifted out of9PARK9.
NOTE: Any failure to meet these expected
responses requires system adjustment or repair.
