DTC Fault Trigger Conditions
DTC Description Fault Trigger Condition IPC U0151:00 Lost Communication With Restraints Control Module: No Sub Type Information Sets in continuous memory in the IPC if the driver safety belt status data is missing for longer than 5 seconds or the airbag warning indicator request message is missing for longer than 2 seconds from the RCM through the BCM over the MS-CAN. Possible Sources
- Communication concern
- Battery voltage concern
- BCM concern
- RCM
- IPC
- BE1 VERIFY THE CUSTOMER CONCERN
- Ignition ON.
- Verify there is an observable symptom present.
Is an observable symptom present?
Yes GO to BE2 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. CLEAR the DTC. - BE2 CHECK THE COMMUNICATION NETWORK
- Using a diagnostic scan tool, perform a network test.
Does the RCM pass the network test?
Yes GO to BE3 No REFER to: Communications Network . - BE3 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 U0151:00 recorded?
Yes REFER to: Body Control Module (BCM) . No GO to BE4 - BE4 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 For DTC U3006:16, GO to Pinpoint Test BK For DTC U3006:17, GO to Pinpoint Test BL No GO to BE5 - BE5 RETRIEVE THE RECORDED DIAGNOSTIC TROUBLE CODES (DTCS) FROM 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 BE6 - BE6 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 can 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.
- Using a diagnostic scan tool, perform the IPC self-test.
Is DTC U0151:00 still present?
Yes GO to BE7 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. CLEAR the DTC. - BE7 CHECK FOR CORRECT RCM (RESTRAINTS CONTROL MODULE) OPERATION
- Ignition OFF.
- Disconnect and inspect the RCM connectors. REFER to: Restraints Control Module (RCM) .
- 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 connectors. Make sure it seats and latches correctly. REFER to: Restraints Control Module (RCM) .
- Operate the system and verify 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) . CLEAR the Diagnostic Trouble Codes (DTCs). REPEAT the self-test. If DTC U0151:00 is still present, GO to BE8 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. - BE8 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 verify 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, Refer to IPC Guided Routine 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.
