Pinpoint Test E : U0131:87

WARNING: This page is about a different car, the 2019 Lincoln MKC. However, it is still accessible from the selected car via links, so may be relevant.
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 performed.

  1. E1 CHECK THE COMMUNICATION NETWORK

    • Ignition ON.

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

    Does the PSCM pass the network test? 

    Yes  GO to  E2
    No  REFER to: Communications Network .

  2. E2 CHECK THE BCM (BODY CONTROL MODULE) CONTINUOUS MEMORY DIAGNOSTIC TROUBLE CODES (CMDTCS)

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

    • Wait 10 seconds.

    • Using a diagnostic scan tool, check the BCM Continuous Memory Diagnostic Trouble Codes (CM DTCs).

    Is DTC U3006:16, U3006:17, U3007:16, U3007:17, U3013:16, U3013:17, U3014:16 or U3014:17 recorded? 

    Yes  For DTC U3006:16, U3007:16, U3013:16 or U3014:16, GO to Pinpoint Test S  For DTC U3006:17, U3007:17, U3013:17 or U3014:17, GO to Pinpoint Test T 
    No  GO to  E3

  3. E3 RETRIEVE THE PSCM (POWER STEERING CONTROL MODULE) DIAGNOSTIC TROUBLE CODES (DTCS)

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

    Are any voltage system related Diagnostic Trouble Codes (DTCs) present? 

    Yes  REFER to: Power Steering .
    No  GO to  E4

  4. E4 RECHECK THE BCM (BODY CONTROL MODULE) CONTINUOUS MEMORY DIAGNOSTIC TROUBLE CODES (CMDTCS)

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

    • Wait 10 seconds.

    • Using a diagnostic scan tool, check the BCM Continuous Memory Diagnostic Trouble Codes (CM DTCs).

    Is DTC U0131:87 still present? 

    Yes  GO to  E5
    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.

  5. E5 CHECK THE GWM (GATEWAY MODULE A) DIAGNOSTIC TROUBLE CODES (DTCS)

    • Using a diagnostic scan tool, check the GWM Continuous Memory Diagnostic Trouble Codes (CM DTCs).

    Are any Diagnostic Trouble Codes (DTCs) recorded? 

    Yes  REFER to: Communications Network .
    No  GO to  E6

  6. E6 CHECK FOR DTC (DIAGNOSTIC TROUBLE CODE) U0131:87 SET IN OTHER MODULES

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

    • Ignition OFF.

    • Ignition ON.

    • Wait 10 seconds.

    • Using a diagnostic scan tool, retrieve all  Continuous Memory Diagnostic Trouble Codes (CM DTCs).

    Is DTC U0131:87 set in other modules? 

    Yes  GO to  E7
    No  GO to  E8

  7. E7 CHECK FOR CORRECT PSCM (POWER STEERING CONTROL MODULE) OPERATION

    • Ignition OFF.

    • Disconnect and inspect the PSCM 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 PSCM 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 service articles: TSB, GSB, SSM or FSA. If a service article exists for this concern, DISCONTINUE this test and FOLLOW the service article instructions. If no service articles address this concern, Refer to EPAS GUIDED ROUTINE
    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.

  8. E8 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 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? 

    Yes  CHECK OASIS for any applicable service articles: TSB, GSB, SSM or FSA. If a service article exists for this concern, DISCONTINUE this test and FOLLOW the service article instructions. If no service articles address this concern, Refer to BCM 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.
