I4 CHECK FOR CORRECT BCM (BODY CONTROL MODULE) OPERATION
Disconnect and inspect the BCM connectors and related in-line connectors. Repair:
corrosion (install new connector or terminals - clean module pins) damaged or bent pins - install new terminals/pins pushed-out pins - install new pins as necessary
Reconnect the BCM connectors and related in-line connectors. Make sure they seat and latch correctly. Operate the system and determine if the concern is still present.
Is the concern still present?
Yes | CHECK OASIS for any applicable Technical Service Bulletins (TSBs). If a TSB exists for this concern, DISCONTINUE this test and FOLLOW TSB instructions. If no Technical Service Bulletins (TSBs) address this concern, Click here to access Guided Routine (BCM). |
|---|---|
No | The system is operating correctly at this time. The concern may have been caused by module connections. ADDRESS the root cause of any connector or pin issues. |
The Body Control Module B (BCMB) Does Not Respond To The Diagnostic Scan Tool
Refer to Wiring Diagrams Cell 14 for schematic and connector information.
Refer to Wiring Diagrams Cell 100 for schematic and connector information.
Normal Operation and Fault Conditions
The Body Control Module B (BCMB) communicates on the MS-CAN, and communicates with the diagnostic scan tool through the HS-CAN2. Diagnostic messages are sent/received through the HS-CAN2 circuits at the DLC, and translated through the GWM to the MS-CAN.
Visual Inspection and Diagnostic Pre-checks
Verify BCM fuses 28 (20A) and 36 (15A) are OK.
