Pinpoint Test B : U0151

WARNING: This page is about a different variant/trim than selected.
  1. Normal Operation and Fault Conditions 

    REFER to: Communications Network - System Operation and Component Description .

    DTC Fault Trigger Conditions 

    DTC Description Fault Trigger Condition
    PCM U0151:00 Lost Communication With Restraints Control Module: No Sub Type Information The PCM sets this DTC if data messages received from the RCM over the High Speed Controller Area Network (HS-CAN) are missing.

    Possible Sources 

    • RCM
    • BCM
    • PCM

  2. B1 VERIFY THE CUSTOMER CONCERN

    • Ignition ON.

    • Verify there is an observable symptom present.

    Is an observable symptom present? 

    Yes  GO to  B2
    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.

  3. B2 CHECK THE COMMUNICATION NETWORK

    • Using a diagnostic scan tool, perform a network test.

    Does the RCM module pass the network test? 

    Yes  GO to  B3
    No  REFER to: Communications Network .

  4. B3 PERFORM RCM (RESTRAINTS CONTROL MODULE) MODULE SELF-TEST

    • Using a diagnostic scan tool, perform a RCM module self-test.

    Are any Diagnostic Trouble Codes (DTCs) recorded? 

    Yes  REFER to: Airbag Supplemental Restraint System (SRS) .
    No  GO to  B4

  5. B4 CHECK THE BCM (BODY CONTROL MODULE) DIAGNOSTIC TROUBLE CODES (DTCS)

    • Using a diagnostic scan tool, retrieve the BCM Diagnostic Trouble Codes (DTCs).

    Are any Diagnostic Trouble Codes (DTCs) recorded? 

    Yes  REFER to: Body Control Module (BCM) .
    No  GO to  B5

  6. B5 PERFORM THE PCM (POWERTRAIN CONTROL MODULE) SELF-TEST

    • Using a diagnostic scan tool, perform the PCM self-test.

    Is DTC P1397 recorded? 

    Yes  REFER to DTC Chart: Powertrain Control Module (PCM) .
    No  GO to  B6

  7. B6 RECHECK THE PCM (POWERTRAIN CONTROL MODULE) 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 PCM self-test.

    Is DTC U0151 still present? 

    Yes  GO to  B7
    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.

  8. B7 CHECK FOR DTC (DIAGNOSTIC TROUBLE CODE) U0151 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 self-test.

    • Retrieve the Diagnostic Trouble Codes (DTCs) from all modules.

    Is DTC U0151:00 set in the BCM? 

    Yes  GO to  B8
    No  GO to  B9

  9. B8 CHECK FOR CORRECT RCM (RESTRAINTS CONTROL MODULE) MODULE OPERATION

    • Ignition OFF.

    • Disconnect and inspect all RCM MODULE 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 RCM MODULE 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 MODULE. 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.

  10. B9 CHECK FOR CORRECT PCM (POWERTRAIN CONTROL MODULE) OPERATION

    • Ignition OFF.

    • Disconnect and inspect PCM 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 PCM 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 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 PCM 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.
