When you press the brake, do you hear a slight tick in the shifter assy? If yes then the shifter assy is bad and will need to be replaced.. If not then you have an issue with your BTSI or Brake/Trans Shift Interlock..

I heard something from the engine compartment the first time but nothing after that(loud sound). The shifter feels like it's stuck in cement and what exactly is BTSI?

Key on, listen for a very faint click in the shifter assy...

DIAGNOSIS AND TESTING - BRAKE/TRANSMISSION SHIFT INTERLOCK SYSTEM

FLOOR SHIFT MODELS

The following chart describes the normal operation of the Brake Transmission Shift Interlock (BTSI) system. If the “expected response” differs from the vehicle's response, then system repair and/or adjustment is necessary.

Refer to the following chart that expected shifter response, depending on ignition key/swich and brake pedal positions.

ACTIONEXPECTED RESPONSE

1. Turn key to the "OFF" position.1. Shifter CAN be shifted out of park.

2. Turn key to the "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 "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.

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 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 number 2 with a test light. The test light should illuminate. 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 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) system. If the “expected response” differs from the vehicle's response, then system repair and/or adjustment is necessary.

Refer to the following chart that expected shifter response, depending on ignition key/swith and brake pedal positions.

ACTIONEXPECTED RESPONSE

1. Turn key to the "OFF" position.1. Shifter CAN be shifted out of park.

2. Turn key to the "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 "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.
