Body Control Module B (BCMB) — 2016 workshop reference 6202

Does the IPC pass the network test?

Yes	GO to B3
No	DIAGNOSE no communication with the IPC. REFER to: Communications Network (418-00 Module Communications Network, Diagnosis and Testing).

Yes

GO to B3

DIAGNOSE no communication with the IPC.

REFER to: Communications Network (418-00 Module Communications Network, Diagnosis and Testing).

B3 CHECK THE BCMB (BODY CONTROL MODULE B) CONTINUOUS MEMORY DIAGNOSTIC TROUBLE CODES (CMDTCS)

Using a diagnostic scan tool, clear the Diagnostic Trouble Codes (DTCs). Wait 10 seconds. Using a diagnostic scan tool, check the BCMB Continuous Memory Diagnostic Trouble Codes (CMDTCs).

Is DTC U3003:62 recorded?

Yes	GO to Pinpoint Test C
No	GO to B4

B4 RETRIEVE THE RECORDED DIAGNOSTIC TROUBLE CODES (DTCS) FROM THE BCM (BODY CONTROL MODULE) SELF-TEST

Using a diagnostic scan tool, perform the IPC self-test.

Is there any DTC recorded?

Yes	REFER to: Instrumentation, Message Center and Warning Chimes (413-01 Instrumentation, Message Center and Warning Chimes, Diagnosis and Testing).
No	GO to B5

B5 RECHECK THE BCMB (BODY CONTROL MODULE B) CONTINUOUS MEMORY DIAGNOSTIC TROUBLE CODES (CMDTCS)

Using a diagnostic scan tool, clear the Diagnostic Trouble Codes (DTCs). Wait 10 seconds. Using a diagnostic scan tool, check the BCM Continuous Memory Diagnostic Trouble Codes (CMDTCs).

Is DTC U0155:87 still present?

Yes	GO to B6
No	The system is operating correctly at this time. The DTC may have been set due to high network traffic or an intermittent fault condition.

B6 CHECK FOR DTC (DIAGNOSTIC TROUBLE CODE) U0155 SET IN OTHER MODULES

Using a diagnostic scan tool, clear the Diagnostic Trouble Codes (DTCs). Ignition OFF. Ignition ON. Wait 10 seconds. Using a diagnostic scan tool, retrieve all Continuous Memory Diagnostic Trouble Codes (CMDTCs).

Is DTC U0155 set in any other module?

Yes	GO to B7
No	GO to B8

B7 CHECK FOR CORRECT IPC (INSTRUMENT PANEL CLUSTER) OPERATION

Disconnect and inspect the IPC connector. 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 IPC connector. Make sure it seats and latches 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, INSTALL a new IPC. REFER to: Instrument Panel Cluster (IPC) (413-01 Instrumentation, Message Center and Warning Chimes, Removal and Installation).
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.
