Pinpoint Test BR : U0151:00
- BR1 VERIFY THE CUSTOMER CONCERN
- Ignition ON.
- Verify there is an observable symptom present.
Is an observable symptom present?
Yes GO to BR2 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. - BR2 CHECK THE COMMUNICATION NETWORK
- Using a diagnostic scan tool, perform the network test.
Does the RCM pass the network test?
Yes GO to BR3 No REFER to: Communications Network . - BR3 PERFORM THE RCM (RESTRAINTS CONTROL MODULE) SELF-TEST
- Using a diagnostic scan tool, perform the RCM self-test.
Are any Diagnostic Trouble Codes (DTCs) recorded?
Yes REFER to: Airbag Supplemental Restraint System (SRS) . No GO to BR4 - BR4 CHECK THE GWM (GATEWAY MODULE A) DIAGNOSTIC TROUBLE CODES (DTCS)
- Using a diagnostic scan tool, check the GWM Continuous Memory Diagnostic Trouble Codes (DTCs).
Are any Diagnostic Trouble Codes (DTCs) recorded?
Yes REFER to: Communications Network . No GO to BR5 - BR5 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 in this article. No GO to BR6 - BR6 RECHECK THE IPC (INSTRUMENT PANEL CLUSTER) DIAGNOSTIC TROUBLE CODES (DTCS)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.
- Using a diagnostic scan tool, clear the Diagnostic Trouble Codes (DTCs).
- Wait 10 seconds.
- Repeat the IPC self-test.
Is DTC U0151:00 still present?
Yes GO to BR7 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. - BR7 CHECK FOR DTC (DIAGNOSTIC TROUBLE CODE) U0151:87 SET IN OTHER MODULES
- Using a diagnostic scan tool, clear all Diagnostic Trouble Codes (DTCs).
- Ignition OFF.
- Ignition ON.
- Wait 10 seconds.
- Using a diagnostic scan tool, perform the continuous memory self-test.
- Retrieve the Continuous Memory Diagnostic Trouble Codes (CMDTCs) from all modules.
Is DTC U0151:87 set in the BCM?
Yes GO to BR8 No GO to BR9 - BR8 CHECK FOR CORRECT RCM (RESTRAINTS CONTROL MODULE) OPERATION
- Ignition OFF.
- Disconnect and inspect the RCM and all 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 RCM and all 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 TSB instructions. If no Technical Service Bulletins (TSBs) address this concern, INSTALL a new RCM. Refer to: Restraints Control Module (RCM) . 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. - BR9 CHECK FOR CORRECT IPC (INSTRUMENT PANEL CLUSTER) OPERATION
