PINPOINT TEST A: THE BRAKE SHIFT INTERLOCK SYSTEM DOES NOT RELEASE/LOCK CORRECTLY

-------------------------------------------------
A1 TEST THE BRAKE LIGHTS


- Apply the brake pedal and view the brake lights.
- Do the brake lights illuminate?

Yes
GO to A2.

No
REFER to Entertainment Systems.

-------------------------------------------------
A2 TEST BSIA POWER CIRCUIT


- Disconnect: Selector Lever Electrical C3245 (2.3L/3.0L engine) or C3233 (3.5L engine).
- Ignition ON.
- Vehicles equipped with a 3.0L or a 2.3L engine, measure the voltage between selector lever harness C3245-1, circuit VET13 (GY/BU), vehicle harness side and ground, while applying the brake pedal.




- Vehicles equipped with a 3.5L engine, measure the voltage between selector lever harness C3233-1, circuit VET13 (GY/BU), vehicle harness side and ground, while applying the brake pedal.




- Is the voltage greater than 10 volts?

Yes
GO to A5.

No
GO to A3.

-------------------------------------------------
A3 TEST THE BSIA POWER CIRCUIT FOR A SHORT TO GROUND


- Ignition OFF.
- Disconnect: Smart Junction Box (SJB) C2280C.
- Vehicles equipped with a 3.0L or a 2.3L engine, measure the resistance between the selector lever harness C3245-1, circuit VET13 (GY/BU), vehicle harness side and ground.




- Vehicles equipped with a 3.5L engine, measure the resistance between selector lever harness C3233-1, circuit VET13 (GY/BU), vehicle harness side and ground.




- Is the resistance greater than 10,000 ohms?

Yes
GO to A4.

No
REPAIR the circuit. TEST the system for normal operation.

-------------------------------------------------
A4 TEST THE BSIA POWER CIRCUIT FOR AN OPEN


- Ignition OFF.
- Vehicles equipped with a 3.0L or a 2.3L engine, measure the resistance between the selector lever harness C3245-1, circuit VET13 (GY/BU), vehicle harness side and SJB C2280C-14, circuit VET13 (GY/BU), vehicle harness side.




- Vehicles equipped with a 3.5L engine, measure the resistance between the selector lever harness C3233-1, circuit VET13 (GY/BU), vehicle harness side and SJB C2280C-14, circuit VET13 (GY/BU), vehicle harness side.




- Is the resistance less than 5 ohms?

Yes
INSTALL a new SJB. TEST the system for normal operation.

No
REPAIR the circuit. TEST the system for normal operation.

-------------------------------------------------
A5 TEST THE BSIA GROUND CIRCUIT


- Ignition OFF.
- Vehicles equipped with a 3.0L or a 2.3L engine, measure the resistance between the selector lever harness C3245-4, circuit GD116 (BK/VT), vehicle harness side and ground.




- Vehicles equipped with a 3.5L engine, measure the resistance between selector lever harness C3233-5, circuit GD116 (BK/VT), vehicle harness side and ground.




- Is the resistance less than 5 ohms?

Yes
INSTALL a new selector lever. REFER to Selector Lever Selector Lever.

No
REPAIR the circuit. TEST the system for normal operation.
