Are any Diagnostic Trouble Codes (DTCs) recorded?
Yes REFER to: Controller Area Network (CAN) Module Communications Network . No GO to B5 - B5 CHECK FOR CORRECT IPC (INSTRUMENT PANEL CLUSTER) OPERATION
- Ignition OFF.
- 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 service articles: TSB, GSB, SSM or FSA. If a service article exists for this concern, DISCONTINUE this test and FOLLOW the service article instructions. If no service articles address this concern, INSTALL a new IPC. REFER to: Instrument Panel Cluster (IPC) . 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.
