- Using a diagnostic scan tool, perform the BCM self-test.
Are any Diagnostic Trouble Codes (DTCs) recorded?
Yes For rear parking aid, REFER to: Parking Aid . For parking aid with rear camera, REFER to: Parking Aid . No GO to BV5 - BV4 CHECK THE GWM (GATEWAY MODULE A) DIAGNOSTIC TROUBLE CODES (DTCS)
- Using a diagnostic scan tool, check the GWM Continuous Memory Diagnostic Trouble Codes (CMDTCs).
Are any Diagnostic Trouble Codes (DTCs) recorded?
Yes REFER to: MODULE COMMUNICATIONS NETWORK . No GO to BV5 - BV5 PERFORM THE IPC (INSTRUMENT PANEL CLUSTER) SELF-TEST
- Using a diagnostic scan tool, perform the IPC self-test.
Is DTC U3003:16 or DTC U3003:17 recorded?
Yes REFER to DTC Chart: IPC . No GO to BV6 - BV6 RECHECK THE IPC (INSTRUMENT PANEL CLUSTER) DIAGNOSTIC TROUBLE CODES (DTCS)

- Wait 10 seconds.
- Repeat the IPC self-test.
Is DTC U0159:00 still present?
Yes GO to BV7 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. - BV7 CHECK FOR CORRECT BCM (BODY CONTROL MODULE) OPERATION
- Ignition OFF.
- 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 all 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?
