Diagnostic Routine D

Diagnostic Overview

B1319:15

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

Normal Operation and Fault Conditions

The BSIA (Brake Shift Interlock Actuator) system is controlled by the BCM (Body Control Module) and is activated when the BCM (Body Control Module) receives a brake pedal applied input.

DTC Fault Trigger Conditions






Pinpoint Test

NOTE: If the scan tool is unable to communicate with the PCM (Powertrain Control Module) or access the transmission PIDs (Parameter Identifications), REFER to Computers and Control Systems Information.

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

1. Install the scan tool and record all DTCs (Diagnostic Trouble Codes).

Was DTC (Diagnostic Trouble Code) B1319:15 set?






2. Check the BSIA (Brake Shift Interlock Actuator) power circuit for an open

1. Disconnect the selector lever C2008.

2. Disconnect the BCM (Body Control Module) C2280B.

3. Inspect for damaged or pushed out terminals.

4. Measure the resistance of circuit CET53 (BU/OG) from the selector lever C2008-3 to the BCM (Body Control Module) C2280B-49.





Is the resistance less than 5 ohms?






3. Check the BSIA (Brake Shift Interlock Actuator) ground circuit for an open

1. Measure the resistance of circuit GD233 (BK) from the selector lever C2008-4 to ground.





Is the resistance less than 5 ohms?






4. Check BSIA (Brake Shift Interlock Actuator) power circuit for voltage

1. Ignition ON.

2. Measure for voltage on circuit CET53 (BU/OG) from the selector lever C2008-3 to ground.





Is any voltage present?
