Pinpoint Test I : U0140:87

WARNING: This page is about a different car, the 2017 Ford F-150. However, it is still accessible from the selected car via links, so may be relevant.

  1. I1 CHECK THE COMMUNICATION NETWORK

    • Ignition ON.

    • Using a diagnostic scan tool, carry out the Network Test.

    Do the GWM and the BCM pass the Network Test? 

    Yes  GO to  I2
    No  DIAGNOSE the no communication with the GWM or the BCM. Refer to: Communications Network .

  2. I2 CHECK THE EPB (ELECTRIC PARKING BRAKE) MODULE CONTINUOUS MEMORY DIAGNOSTIC TROUBLE CODES (CMDTCS)

    • Using a diagnostic scan tool, carry out the EPB module self-test.

    • Clear the Diagnostic Trouble Codes (DTCs).

    • Ignition OFF.

    • Ignition ON.

    • Repeat the EPB module self-test.

    • Record all EPB module Diagnostic Trouble Codes (DTCs).

    Is DTC U0140:87 retrieved again? 

    Yes  GO to  I3
    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.

  3. I3 REVIEW THE RECORDED DIAGNOSTIC TROUBLE CODES (DTCS) FROM THE EPB (ELECTRIC PARKING BRAKE) SELF-TEST

    • Review the recorded Diagnostic Trouble Codes (DTCs) from the EPB module self-test.

    Is DTC U3003:16 or U3003:17 present in the EPB module? 

    Yes  For DTC U3003:16, GO to Pinpoint Test A  For DTC U3003:17, GO to Pinpoint Test C 
    No  GO to  I4

  4. I4 CHECK FOR DIAGNOSTIC TROUBLE CODES (DTCS) IN THE GWM (GATEWAY MODULE A)

    • Using a diagnostic scan tool, carry out the GWM self-test.

    Are any Diagnostic Trouble Codes (DTCs) present in the GWM? 

    Yes  DIAGNOSE the GWM Diagnostic Trouble Codes (DTCs). REFER to: Communications Network .
    No  GO to  I5

  5. I5 CHECK FOR DIAGNOSTIC TROUBLE CODES (DTCS) IN THE BCM (BODY CONTROL MODULE)

    • Using a diagnostic scan tool, carry out the BCM self-test.

    • Retrieve and record all Diagnostic Trouble Codes (DTCs) from the BCM self-test.

    Are any Diagnostic Trouble Codes (DTCs) present in the BCM? 

    Yes  DIAGNOSE the BCM Diagnostic Trouble Codes (DTCs). REFER to: Body Control Module (BCM) .
    No  GO to  I6

  6. I6 CHECK FOR DTC (DIAGNOSTIC TROUBLE CODE) U0140:XX SET IN OTHER MODULES

    • Using the diagnostic scan tool, carry out the self-test for all modules.

    • Retrieve and record the Continuous Memory Diagnostic Trouble Codes (CMDTCs) from all modules.

    Is DTC U0140:xx set in 1 or more modules other than the EPB module? 

    Yes  GO to  I7
    No  GO to  I8

  7. I7 CHECK FOR CORRECT BCM (BODY CONTROL MODULE) OPERATION

    • Ignition OFF.

    • Disconnect all BCM electrical connectors.

    • Disconnect all related in-line electrical connectors between the BCM and the EPB module.

    • Using a good light source, inspect all disconnected electrical connectors for the following:

      • corrosion - install new connector or terminal and clean the module pins
      • damaged or bent pins - install new terminals or pins
      • pushed-out pins - install new pins as necessary
      • spread terminals - install new terminals as necessary

    • Connect all related in-line electrical connectors between the BCM and the EPB module. Make sure they seat and latch correctly.

    • Connect all 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 Technical Service Bulletins (TSBs). If a TSB exists for this concern, DISCONTINUE this test and FOLLOW the TSB instructions. If no Technical Service Bulletins (TSBs) address this concern, BCM Hardware 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.

  8. I8 CHECK FOR CORRECT EPB (ELECTRIC PARKING BRAKE) MODULE OPERATION

    • Ignition OFF.

    • Disconnect EPB module C3675 .

    • Disconnect all related in-line electrical connectors between the EPB module and the BCM.

    • Using a good light source, inspect the electrical connectors for the following:

      • corrosion - install new connector or terminal and clean the module pins
      • damaged or bent pins - install new terminals or pins
      • pushed-out pins - install new pins as necessary
      • spread terminals - install new terminals as necessary

    • Connect all related in-line electrical connectors between the EPB module and the BCM. Make sure they seat and latch correctly.

    • Connect EPB module C3675 . 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 Technical Service Bulletins (TSBs) address this concern, INSTALL a new EPB module. REFER to: Park Brake Control Module (PBM) .
    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.
