Body Control Module B (BCMB) — 2016 workshop reference 6205

C6 CHECK THE BCMB (BODY CONTROL MODULE B) VOLTAGE PID (PARAMETER IDENTIFICATION)

Ignition OFF. Ignition ON. Measure and record battery voltage:

Click to display connectors

Positive Lead	Measurement / Action	Negative Lead

Using a diagnostic scan tool, view the BCMB PID VPWR_BCMB.

Is the recorded battery voltage within 0.2 volt of the PID?

Yes	GO to C9
No	GO to C7

C7 CHECK THE BCMB (BODY CONTROL MODULE B) VOLTAGE SUPPLY CIRCUIT

Ignition OFF. Disconnect BCM C2280C. Ignition ON. Measure:

Click to display connectors

Positive Lead	Measurement / Action	Negative Lead
C2280C-1		Ground

Is the voltage within 0.2 volt of the recorded battery voltage?

Yes	GO to C8
No	REPAIR the circuit for high resistance.

C8 CHECK THE BCMB (BODY CONTROL MODULE B) GROUND

Ignition OFF. Disconnect BCM C2280A. Measure:

Click to display connectors

Positive Lead	Measurement / Action	Negative Lead
C2280A-13		Ground

Is the resistance less than 3 ohms?

Yes	GO to C9
No	REPAIR the circuit for high resistance.

C9 CHECK FOR CORRECT BCM (BODY CONTROL MODULE) OPERATION

Disconnect and inspect all BCM 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. 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.
