Pinpoint Test

NOTE: If the scan tool is unable to communicate with the Powertrain Control Module (PCM) or access the transmission Parameter Identifications (PIDs), REFER to INTRODUCTION - GASOLINE MODELS .

Read and record all Diagnostic Trouble Codes (DTCs)
1. Install the scan tool and record all Diagnostic Trouble Codes (DTCs).
  - Was Diagnostic Trouble Code (DTC) B1319:11 set?
  - Yes: GO to 2 on page 2.
  - No: The issue may not be the Brake Shift Interlock Actuator (BSIA) system. REFER to SYMPTOM CHART: EXTERNAL CONTROLS .
Check Body Control Module (BCM) FUSE 18 (10A)
1. Ignition OFF.
2. Remove the Body Control Module (BCM) fuse 18 (10A).
3. Check the Body Control Module (BCM) fuse 18 (10A).
  - Is the resistance less than 5 ohms?
  - Yes: GO to 3 on page 2.
  - No: GO to 4 on page 2.
Check the Body Control Module (BCM) for an internal short
1. Disconnect the Body Control Module (BCM) C2280B.
2. Inspect for damaged or pushed out terminals.
3. Install a new fuse.
  - Did the fuse fail?
  - Yes: INSTALL a new Body Control Module (BCM). REFER to BODY CONTROL MODULE (BCM) - WITH INTELLIGENT ACCESS (IA) or REFER to BODY CONTROL MODULE (BCM) - WITHOUT INTELLIGENT ACCESS (IA) .
  - No: GO to 4 on page 2.
Check the Brake Shift Interlock Actuator (BSIA) power circuit for a short to ground
1. Disconnect the selector lever C2008.
2. Inspect for damaged or pushed out terminals.
3. Measure the resistance of circuit CET53 (BU/OG) from the selector lever C2008-3 to ground.

  - Is the resistance greater than 10,000 ohms?
  - Yes: INSTALL a new selector lever. REFER to SELECTOR LEVER .
  - No: REPAIR circuit CET53 (BU/OG) for a short to ground. CLEAR the Diagnostic Trouble Code (DTC). TEST the system for normal operation.
