DTC Fault Trigger Conditions






Pinpoint Test

1. Read and record all DTCs (Diagnostic Trouble Codes)

Is DTC (Diagnostic Trouble Code) B1319:11 set?






2. Check the BSIA (Brake Shift Interlock Actuator) power circuit for a short to ground

1. Disconnect the floor shifter C3245.

2. Disconnect the BCM (Body Control Module) C2280C.

3. Inspect the connectors for damaged or pushed out terminals.

4. Measure the resistance of circuit CET52 (GN) from the floor shifter C3245-3 to ground.





Is the resistance greater than 10,000 ohms?
