- F1 VERIFY THE CUSTOMER CONCERN
- Ignition ON.
- Verify there is an observable symptom present.
Is an observable symptom present?
Yes GO to F2 No The system is operating normally at this time. The DTC may have been set due to high network traffic or an intermittent fault condition. - F2 CHECK THE COMMUNICATION NETWORK
- Using a diagnostic scan tool, perform a network test.
Does the IPC pass the network test?
Yes GO to F3 No DIAGNOSE no communication with the IPC. Refer to: Communications Network . - F3 RETRIEVE THE RECORDED DIAGNOSTIC TROUBLE CODES (DTCS) FROM THE BCM (BODY CONTROL MODULE) SELF-TEST
- Using a diagnostic scan tool, perform the BCM self-test.
Is DTC U3003:16 or DTC U3003:17 recorded?
Yes For DTC U3003:16, GO to Pinpoint Test N For DTC U3003:17, GO to Pinpoint Test O No GO to F4 - F4 RETRIEVE THE RECORDED DIAGNOSTIC TROUBLE CODES (DTCS) FROM THE IPC (INSTRUMENT PANEL CLUSTER) SELF-TEST
- Using a diagnostic scan tool, perform the IPC self-test.
Is DTC U3006:16 or DTC U3006:17 recorded?
Yes REFER to: Instrumentation, Message Center and Warning Chimes . No GO to F5 - F5 RECHECK THE BCM (BODY CONTROL MODULE) CONTINUOUS MEMORY DIAGNOSTIC TROUBLE CODES (CMDTCS)NOTE: If new modules were installed prior to the DTC being set, the module configuration may be incorrectly set during the PMI or the PMI may not have been carried out.
- Clear the Diagnostic Trouble Codes (DTCs).
- Ignition OFF.
- Ignition ON.
- Wait 10 seconds.
- Using a diagnostic scan tool, perform the BCM self-test.
Is DTC U0155:00 still present?
Yes GO to F6 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. - F6 CHECK FOR DTC (DIAGNOSTIC TROUBLE CODE) U0155:00 SET IN OTHER MODULES
- Clear all 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 U0155:00 set in any other module?
Yes GO to F7 No GO to F8 - F7 CHECK FOR CORRECT IPC (INSTRUMENT PANEL CLUSTER) OPERATION
- Disconnect and inspect 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
- Connect 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 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, Refer to IPC Hardware Testing . 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. - F8 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
- Connect the BCM connectors. Make sure they seat and latch correctly.

Is the concern still present?
Yes CHECK 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 BCM. Refer to: Body Control Module (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.
