Pinpoint Test

Refer to Wiring Diagram Set 37, Shift Interlock for schematic and connector information Electrical Diagrams.

PINPOINT TEST A : 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)

- Ignition OFF.

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

Is the resistance less than 5 ohms?

Yes
GO to A3.

No
INSTALL a new fuse. CLEAR the DTCs. REPEAT the self-test.

A3 TEST THE BSIA (Brake Shift Interlock Actuator) POWER CIRCUIT

- Disconnect: Selector Lever Harness C2096.

- Ignition ON.

- Measure the voltage between selector lever harness C2096-1 circuit CET53 (BU/OG) 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 C2096-1, circuit CET53 (BU/OG) and ground.





Is the resistance greater than 10,000 ohms?

Yes
GO to A5.

No
REPAIR circuit CET53 (BU/OG) for a short to ground. TEST the system for normal operation.

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

- Measure the resistance between selector lever harness C2096-1, circuit CET53 (BU/OG) and SJB (Smart Junction Box) C2280C-23, circuit CET53 (BU/OG).





Is the resistance less than 5 ohms?

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

No
REPAIR circuit CET53 (BU/OG) for an open.

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

- Ignition OFF.

- Measure the resistance between floor selector lever harness C2096-4, circuit GD112 (BK/GN) and ground.





Is the resistance less than 5 ohms?

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

No
REPAIR circuit GD112 (BK/GN). TEST the system for normal operation.
