viced as a complete assembly (Fig. 1), except for the
components listed here. They are the key cylinder,
ignition switch, lock cylinder housing, multi-function
switch, clockspring, halo lamp, speed control
switches, driver airbag, trim shrouds, steering wheel
and steering column intermediate shaft (Fig. 2).
These replaceable components of the steering column
can be serviced without requiring removal of the
steering column from the vehicle.

LOCK CYLINDER HOUSING
DESCRIPTION - IGNITION INTERLOCK
All vehicles equipped with automatic transaxles
have an interlock system. The system prevents shift-
ing the vehicle out of Park unless the ignition lock
cylinder is in the Unlock, Run or Start position. In
addition, the operator cannot rotate the key to the
lock position unless the shifter is in the park posi-
tion. On vehicles equipped with floor shift refer to
the - Transaxle for Automatic Transmission Shifter/
Ignition Interlock.

SHIFT INTERLOCK SOLENOID
DESCRIPTION
The Brake/Transmission Shift Interlock system
consists of an electro-magnetic solenoid mounted to
the steering column (Fig. 291). The solenoid's plunger
consists of an integrated hook, which operates the
shift lever pawl (part of shift lever assembly), and a
plunger return spring (Fig. 292). The solenoid also
has an integrated bracket, which facilitates fastening
to the steering column.
OPERATION
The Brake/Transmission Shift Interlock (BTSI) Sole-
noid 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 con-
trolled 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. 293). The ground side of the solenoid is
controlled by a driver within the IPM. It relies on volt-
age 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-energizing 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. 294). 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. 295), allow-
ing the shift lever to be moved into any gear position.

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
9PARK9and try to remove
the key.5. Key can be removed
(after returning to9LOCK9
position).
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 repair. Refer to the
appropriate Diagnostic Information.

OPERATION
The relay is supplied fused B+ voltage, energized
by the PCM/TCM, and is used to supply power to the
solenoid pack when the transmission is in normal
operating mode. When the relay is ªoffº, no power is
supplied to the solenoid pack and the transmission is
in ªlimp-inº mode. After a controller reset (ignition
key turned to the ªrunº position or after cranking
engine), the PCM/TCM energizes the relay. Prior to
this, the PCM/TCM verifies that the contacts are
open by checking for no voltage at the switched bat-
tery terminals. After this is verified, the voltage at
the solenoid pack pressure switches is checked. After
the relay is energized, the PCM/TCM monitors the
terminals to verify that the voltage is greater than 3
volts.
TRANSMISSION RANGE
SENSOR
DESCRIPTION
The Transmission Range Sensor (TRS) is mounted
to the top of the valve body inside the transaxle and
can only be serviced by removing the valve body. The
electrical connector extends through the transaxle
case (Fig. 328).
The Transmission Range Sensor (TRS) has four
switch contacts that monitor shift lever position and
send the information to the PCM/TCM.The TRS also has an integrated temperature sen-
sor (thermistor) that communicates transaxle tem-
perature to the TCM and PCM (Fig. 329).
OPERATION
The Transmission Range Sensor (TRS) (Fig. 328)
communicates shift lever position (SLP) to the PCM/
TCM as a combination of open and closed switches.
Each shift lever position has an assigned combination
of switch states (open/closed) that the PCM/TCM
receives from four sense circuits. The PCM/TCM inter-
prets this information and determines the appropriate
transaxle gear position and shift schedule.

SUNROOF
DESCRIPTION
WARNING: Keep fingers and other body parts out
of sunroof opening at all times.
The sun roof features consists of: (Fig. 1)
²Sun roof glass
²Sun roof sun shade
The sunroof power sliding glass panel and sun-
shade can be positioned anywhere along its travel,
rearward of glass panel front edge.
The sunroof is electrically operated from a switch
located in the overhead console. To operate the sun-
roof the ignition switch must be in the Accessory or
On/Run position. Both switchs are a rocker style
design that open or close the sunroof. When pressing
and releasing the open button once, the sunroof will
express open to the comfort stop and the wind deflec-
tor will raise. If the button is pressed a second time,
the sunroof will continue to open to full travel unless
the button is released, at which time it will stop in
that position. Pressing and holding the close button
will close the sunroof. If the close button is released
before the glass fully closes, the sunroof will stop in
that position. The vent switch operates in a similar
manor. The sunroof will also operate for up to fifteen
minutes after the ignition key is turned off for cus-
tomer comfort and convenance while parking.
DIAGNOSIS AND TESTING - SUNROOF
Refer to Sunroof Diagnostic Chart for possible
causes. Before beginning sunroof diagnostics verify
that all other power accessories are in proper operat-
ing condition. If not, a common electrical problem
may exist. Refer to Wiring Diagrams, in this publica-
tion for circuit, splice and component descriptions.
Check the condition of the circuit protection (20 amp
circuit breaker in the Junction Block). Inspect all
wiring connector pins for proper engagement and
continuity. Check for battery voltage at the power
sunroof controller, refer to Wiring Diagrams, for cir-
cuit information. If battery voltage of more than 10
volts is detected at the controller, proceed with the
following tests (the controller will not operate at less
than 10 volts).
Before beginning diagnosis for wind noise or water
leaks, verify that the problem was not caused by
releasing the control switch before the sunroof was
fully closed. The sunroof module has a water-man-
agement system. If however, the sunroof glass is in a
partial closed position, high pressure water may be
forced beyond the water management system bound-
aries and onto the headlining.
