(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
lamp switch. Repair the open or replace brake lamp
switch as necessary.
(7) Depress the brake pedal. The test light should
go out. If it does not, there is a short in the ground
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 shift
lever can still be moved freely in and out of PARK
without the brake pedal depressed, replace the BTSI
solenoid.
BRAKE/TRANSMISSION SHIFT INTERLOCK
SYSTEM (FLOOR SHIFT)
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. 36)
and brake pedal positions.
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.
SHIFTER 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. The solenoid is part of
the interlock cable assembly.
(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 moving the shifter
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 the
interlock cable must be replaced. If the shift lever
still does not move from the park position, the prob-
lem is in the shift lever assembly or the ignition
interlock cassette.

1 – ACC
2 – LOCK
3 – OFF
4 – ON/RUN
5 – START
ACTION EXPECTED RESPONSE
1. Turn key to the “OFF”
position. 1. Shifter CAN be shifted
out of park.
2. Turn key to the
9
ON/RUN” position.
2. Shifter CANNOT be
shifted out of park.
3. Turn key to the
“ON/RUN” position 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 the “LOCK” or
9
ACC”
position.
4. Key cannot be
returned to the “LOCK” or
“ACC” position.
5. Return shifter to
“PARK” and try to remove
the key. 5. Key can be removed
(after returning to “LOCK”
position).
6. With the key removed,
try to shift out of “PARK”. 6. Shifter cannot be
shifted out of “PARK”.
NOTE: Any failure to meet these expected
responses requires system adjustment or repair.
