circuit or brake lamp switch. Repair the short or
replace brake lamp switch as necessary.
(8) Reconnect the wire connector to the solenoid.
If the circuit passes the above test and the shifter
can still be moved freely in and out of PARK without
the brake pedal depressed, replace the interlock
cable.
COLUMN SHIFT MODELS
The following chart describes the normal operation
of the Brake Transmission Shift Interlock (BTSI) sys-
tem. If the "expected response" differs from the vehi-
cle's response, then system repair and/or adjustment
is necessary.
Refer to the following chart that expected shifter
response, depending on ignition key/switch (Fig. 374)
and brake pedal positions.
Fig. 374 Ignition Key/Switch Positions
1 - ACC
2 - LOCK
3 - OFF
4 - ON/RUN
5 - START
ACTION
1. Turn key to the OFF
position.
2. Turn key to the
ON/RUN position.
3. Turn key to the
ON/RUN position and
depress the brake pedal.
4. Leave shifter in any
gear and try to return key
to the LOCK or ACC
position.
5. Return shifter to
PARK and try to remove
the key.
EXPECTED RESPONSE
1. Shifter CAN be shifted
out of park.
2. Shifter CANNOT be
shifted out of park.
3. Shifter CAN be shifted
out of park.
4. Key cannot be
returned to the LOCK or
ACC position.
5. Key can be removed
(after returning to LOCK
position).
ACTION
6. With the key removed,
try to shift out of PARK .
NOTE: Any failure to meet these expected
responses requires system adjustment or repair.
If the floor shifter cannot be moved out of the
PARK position, refer to Shifter Locked In Place
below. If the shift lever can be shifted out of PARK
without the brake pedal depressed, refer to Circuit
Test below.
SHIFT LEVER LOCKED IN PLACE
(1) Remove the instrument panel cover below the
steering column, then remove the steering column
shrouds to gain access to the brake transmission
shift interlock (BTSI) solenoid.
(2) Disconnect the wire connector from the rear of
the BTSI solenoid.
(3) Insert the ignition key and turn it to the ON
position.
(4) With the brakes applied, try shifting the trans-
mission shift lever out of the PARK position.
• If the lever now moves freely in and out of
PARK, perform the Circuit Test below.
• If the shift lever still does not move from the
PARK position, remove the BTSI solenoid from the
shift lever assembly.
If the shift lever now moves freely in and out of
the park position, the BTSI solenoid is faulty and
must be replaced. If the shift lever still does not
move from the park position, the problem is in the
shift lever assembly or the ignition interlock cassette.
CIRCUIT TEST
(1) Check the system fuse in the junction block
(An open or blown fuse would allow the shift lever to
be moved in and out of the PARK position without
the brake pedal applied).
(2) Remove the instrument panel cover below the
steering column, then remove the steering column
shrouds to gain access to the brake transmission
shift interlock (BTSI) solenoid.
(3) Disconnect the wire connector from the rear of
the BTSI solenoid.
(4) Insert the ignition key and turn it to the ON
position.
(5) Back-probe the wire connector's terminal num-
ber 2 with a test light. The test light should illumi-
nate. If not, there is an open or short in the ignition
feed circuit leading to the BTSI solenoid. Repair the
open or short.
(6) Next, back-probe the wire connector with a test
light, placing the test light in series between the two
wires. At this point, the test light should illuminate.
If not, there is an open in the ground circuit or brake
TRANSAXLE 21 - 141
EXPECTED RESPONSE
6. Shifter cannot be
shifted out of PARK .
