Pinpoint Test G : DTC (Diagnostic Trouble Code) U0140:87

WARNING: This page is about a different car, the 2019 Ford F-550 Super Duty, 2019 Ford F-450 Super Duty, 2019 Ford F-350 Super Duty, and 2019 Ford F-250 Super Duty. However, it is still accessible from the selected car via links, so may be relevant.

  1. G1 VERIFY THE CUSTOMER CONCERN

    • Ignition ON.

    • Verify there is an observable symptom present.

    Is an observable symptom present? 

    Yes  GO to  G2
    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.

  2. G2 CHECK THE COMMUNICATION NETWORK

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

    Does the BCM pass the network test? 

    Yes  GO to  G3
    No  See the Symptom Chart: Communication Network, the BCM does not respond to the diagnostic scan tool. REFER to: Communications Network .

  3. G3 PERFORM THE IPMA (IMAGE PROCESSING MODULE A) SELF-TEST

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

    Are any non-network Diagnostic Trouble Codes (DTCs) present? 

    Yes  DIAGNOSE all non-network Diagnostic Trouble Codes (DTCs). REFER to IPMA DTC Chart  .
    No  GO to  G4

  4. G4 PERFORM THE BCM (BODY CONTROL MODULE) SELF-TEST

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

    Are any non-network Diagnostic Trouble Codes (DTCs) present? 

    Yes  DIAGNOSE all non-network Diagnostic Trouble Codes (DTCs). REFER to: Body Control Module (BCM) .
    No  GO to  G5

  5. G5 PERFORM THE GWM (GATEWAY MODULE A) SELF-TEST

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

    Are any Diagnostic Trouble Codes (DTCs) present? 

    Yes  See the GWM DTC Chart. REFER to: Communications Network .
    No  GO to  G6

  6. G6 RECHECK THE IPMA (IMAGE PROCESSING MODULE A) DIAGNOSTIC TROUBLE CODES (DTCS)

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

    • Ignition OFF.

    • Ignition ON.

    • Wait 10 seconds.

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

    • Check the IPMA Diagnostic Trouble Codes (DTCs).

    Is DTC U0140:87 still present? 

    Yes  GO to  G7
    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.

  7. G7 CHECK FOR OTHER CAUSES OF COMMUNICATION NETWORK CONCERN

    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.

    • CHECK the vehicle service history for recent service actions related to the BCM, GWM or IPMA. If recent service history is found:

      • verify correct replacement module was installed

        • HVBOM may be used to verify correct part fitment

      • verify the configuration of replacement module was correct

        • re-configure module using as-built data if prior configuration is suspect

      • verify the module was not obtained from a like vehicle and installed into customer vehicle

        • return the swapped module to source vehicle and obtain new replacement module

    • Operate the system and determine if the observable symptom is still present.

    Is the observable symptom still present? 

    Yes  GO to  G8
    No  The system is operating correctly at this time. The concern may have been due to incorrect parts replacement procedures or incorrect module configuration.

  8. G8 CHECK FOR CORRECT BCM (BODY CONTROL MODULE) OPERATION

    • Ignition OFF.

    • Disconnect and inspect the BCM connectors and related in-line connectors.

    • Repair:

      • corrosion (install new connector or terminals - clean module pins)
      • damaged pins - install new terminals/pins
      • pushed-out pins - install new pins as necessary

    • Reconnect the BCM connectors and 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 the TSB instructions. If no Technical Service Bulletins (TSBs) address this concern, Refer to BCM 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.
