Pinpoint Tests
PINPOINT TEST A: THE BSIA SYSTEM DOES NOT RELEASE/LOCK CORRECTLY
NOTE: Inspect the selector lever cable before proceeding with this pinpoint test.
-------------------------------------------------
A1 CHECK THE BRAKE LIGHTS
- Apply the brake pedal and observe the brake lights.
- Do the brake lights illuminate?
Yes
GO to A2.
No
REFER to Exterior Lighting Testing and Inspection.
-------------------------------------------------
A2 CHECK THE BCM FUSE 18 (10A)
- Check fuse: Body Control Module (BCM) 18 (10A).
- Is the resistance less than 5 ohms?
Yes
GO to A4.
No
GO to A3.
-------------------------------------------------
A3 CHECK THE BSIA POWER CIRCUIT FOR A SHORT TO GROUND
- Disconnect: Brake Shift Interlock Actuator (BSIA) C2008.
- Disconnect: BCM C2280B.
- Inspect C2008 and C2280B for damaged, pushed-out terminals or loose wires.
- Measure the resistance between the BSIA C2008-4, circuit CET53 (BU/OG), harness side and ground.
- Is the resistance greater than 10,000 ohms?
Yes
GO to A4.
No
REPAIR circuit CET53 (BU/OG) for a short to ground. CLEAR the DTC. TEST the system for normal operation.
-------------------------------------------------
A4 CHECK THE BSIA POWER CIRCUIT FOR AN OPEN
- Measure the resistance between the BSIA C2008-4, circuit CET53 (BU/OG) and BCM C2280B-49, harness side.
- Is the resistance less than 5 ohms?
Yes
GO to A5.
No
REPAIR circuit CET53 (BU/OG) for an open. CLEAR the DTC. TEST the system for normal operation.
-------------------------------------------------
A5 CHECK THE BSIA GROUND CIRCUIT FOR AN OPEN
- Measure the resistance between the BSIA C2008-1, circuit GD133 (BK), harness side and ground.
- Is the resistance less than 5 ohms?
Yes
GO to A6.
No
REPAIR circuit GD133 (BK) for an open. CLEAR the DTC. TEST the system for normal operation.
-------------------------------------------------
A6 CHECK THE BSIA POWER CIRCUIT FOR VOLTAGE
- Connect: BCM C2280B.
- Ignition ON.
- Measure the voltage between the BSIA C2008-4, circuit CET53 (BU/OG), harness side and ground, while applying the brake pedal.
- Is the voltage greater than 10 volts with the brake pedal applied?
Yes
REPLACE the BSIA. REFER to Brake Shift Interlock Actuator - Column Shift Brake Shift Interlock Actuator - Column Shift. CLEAR the DTC. TEST the system for normal operation.
No
REPLACE the BCM. CLEAR the DTC. TEST the system for normal operation.
