Pinpoint Test I : DTC (Diagnostic Trouble Code) U0100:00, DTC (Diagnostic Trouble Code) U0101:00

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

  1. I1 VERIFY THE CUSTOMER'S CONCERN

    • Ignition ON.

    • Verify if there is an observable symptom present.

    Is an observable symptom present? 

    Yes  GO to  I2
    No  CLEAR the DTC. The system is operating correctly at this time. The DTC may have been set due to high network traffic or an intermittent fault condition.

  2. I2 VERIFY THAT THE DIAGNOSTIC SCAN TOOL COMMUNICATES WITH THE PCM (POWERTRAIN CONTROL MODULE)

    • Connect a diagnostic scan tool.

    • Check that a vehicle session can be established using the diagnostic scan tool.

    Can a vehicle session be established? 

    Yes  GO to  I3
    No  See the Symptom Chart: Communication Network. REFER to: Communications Network .

  3. I3 PERFORM THE SODL (SIDE OBSTACLE DETECTION CONTROL MODULE LH) AND SODR (SIDE OBSTACLE DETECTION CONTROL MODULE RH) SELF-TEST

    • Using a diagnostic scan tool, perform the SODL and SODR self-test.

    • Clear the Diagnostic Trouble Codes (DTCs).

    • Wait 10 seconds.

    • Repeat the SODL and SODR self-test.

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

    Yes  DIAGNOSE all non-network Diagnostic Trouble Codes (DTCs). REFER to SODL and SODR DTC Chart .
    No  GO to  I4

  4. I4 PERFORM THE PCM (POWERTRAIN CONTROL MODULE) SELF-TEST

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

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

    Yes  DIAGNOSE all non-network Diagnostic Trouble Codes (DTCs). See Electronic Engine Control, PCM DTC Chart. Refer to the appropriate Electronic Engine Controls article.
    No  GO to  I5

  5. I5 PERFORM THE BCM (BODY CONTROL MODULE) SELF-TEST

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

    Are any Diagnostic Trouble Codes (DTCs) present? 

    Yes  See the BCM DTC Chart. REFER to: Body Control Module (BCM) .
    No  GO to  I6

  6. I6 RECHECK THE SODL (SIDE OBSTACLE DETECTION CONTROL MODULE LH) AND SODR (SIDE OBSTACLE DETECTION CONTROL MODULE RH) DIAGNOSTIC TROUBLE CODES (DTCS)

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

    • Ignition OFF.

    • Ignition ON.

    • Wait 10 seconds.

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

    • Check the SODL and SODR Diagnostic Trouble Codes (DTCs).

    Is DTC U0100:00 and/or DTC U0101:00 still present? 

    Yes  GO to  I7
    No  The system is operating correctly at this time. This DTC may have been set due to high network traffic or an intermittent fault condition.

  7. I7 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 PCM, SODL, SODR, or BCM. 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  I8
    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. I8 CHECK FOR CORRECT PCM (POWERTRAIN CONTROL MODULE) OPERATION

    • Ignition OFF.

    • Disconnect and inspect all PCM and related in-line 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 PCM 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, INSTALL a new PCM. Refer to the appropriate Electronic Engine Controls article.
    No  The system is operating correctly at this time. Concern may have been caused by a loose or corroded connector. ADDRESS the root cause of any connector or pin issues.
