- Ignition ON.
- Verify there is an observable symptom present.
Is an observable symptom present?
Yes GO to R2 No Clear the DTC. The system is operating normally at this time. The DTC may have been set due to high network traffic or an intermittent fault condition. - R2 CHECK THE COMMUNICATION NETWORK
- Using a diagnostic scan tool, perform the network test.
Do the IPC and the GWM pass the network test?
Yes GO to R3 No REFER to: Communications Network . REFER to: Instrumentation, Message Center and Warning Chimes . - R3 PERFORM THE IPC (INSTRUMENT PANEL CLUSTER) SELF-TEST
- Using a diagnostic scan tool, perform the IPC self-test.
Are any Diagnostic Trouble Codes (DTCs) recorded?
Yes REFER to: Instrumentation, Message Center and Warning Chimes . No GO to R4 - R4 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: Communications Network . No GO to R5 - R5 RECHECK THE PAM (PARKING ASSIST CONTROL MODULE) DIAGNOSTIC TROUBLE CODES (DTCS)
- Using a diagnostic scan tool, clear the Diagnostic Trouble Codes (DTCs).
- Operate the system and test for normal operation.
- Check the PAM Continuous Memory Diagnostic Trouble Codes (CMDTCs).
Is DTC U0155:00 present?
Yes GO to R6 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. - R6 CHECK FOR DTC (DIAGNOSTIC TROUBLE CODE) U0155:00 SET IN OTHER MODULES
- Using a diagnostic scan tool, clear all Diagnostic Trouble Codes (DTCs).
- Ignition OFF.
- Wait 10 seconds.
- Ignition ON
- Wait 10 seconds.
- Using a diagnostic scan tool, retrieve the Continuous Memory Diagnostic Trouble Codes (CMDTCs) from all modules.
Is DTC U0155:00 set in other modules?
Yes GO to R7 No GO to R8 - R7 CHECK FOR CORRECT IPC (INSTRUMENT PANEL CLUSTER) OPERATION
- Ignition OFF.
- Disconnect and inspect all IPC and related in-line 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 IPC and related in-line 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 the TSB instructions. If no TSB addresses this concern, refer to IPC Guided Routine Testing . No The system is operating correctly at this time. Concern may have been caused by a loose or corroded connector. ADDRESS the root cause of any connector or pin issues. - R8 CHECK FOR CORRECT BCM (BODY CONTROL MODULE) OPERATION
- Ignition OFF.
- Disconnect and inspect all BCM and related in-line 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
