Refer to Wiring Diagram Set 37, Shift Interlock for schematic and connector information. [1][2]Diagrams By Number

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 Lighting and Horns.

A2 TEST SJB (Smart Junction Box) FUSE 5 (10A)

- Check fuse: Smart Junction Box (SJB) 5 (10A).

Is the resistance less than 5 ohms?

Yes
GO to A3.

No
INSTALL a new fuse. GO to A3.

A3 TEST BSIA (Brake Shift Interlock Actuator) POWER CIRCUIT

- Disconnect: Selector Lever Electrical C3233.

- Ignition ON.

- Measure the voltage between selector lever harness C3233-1, circuit CET53 (BU/OG), vehicle harness side and ground, while applying the brake pedal.





Is the voltage greater than 10 volts?

Yes
GO to A6.

No
GO to A4.

A4 TEST THE BSIA (Brake Shift Interlock Actuator) POWER CIRCUIT FOR A SHORT TO GROUND

- Ignition OFF.

- Disconnect: SJB (Smart Junction Box) C2280C.

- Measure the resistance between selector lever harness C3233-1, circuit CET53 (BU/OG), vehicle harness side and ground.





Is the resistance greater than 10,000 ohms?

Yes
GO to A5.

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

A5 TEST THE BSIA (Brake Shift Interlock Actuator) POWER CIRCUIT FOR AN OPEN

- Ignition OFF.

- Measure the resistance between the selector lever harness C3233-1, circuit CET53 (BU/OG), vehicle harness side and SJB (Smart Junction Box) C2280C-23, circuit CET53 (BU/OG), vehicle harness side.





Is the resistance less than 5 ohms?

Yes
INSTALL a new SJB (Smart Junction Box). TEST the system for normal operation.

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

A6 TEST THE BSIA (Brake Shift Interlock Actuator) GROUND CIRCUIT

- Ignition OFF.

- 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 .

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