Pinpoint Test I : Lost Communication With ECM / Pcm "A"

  1. I1 CHECK THE COMMUNICATION NETWORK

    • Ignition ON.

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

    Do both the PCM and the GWM pass the Network Test? 

    Yes  GO to  I2
    No  DIAGNOSE the no communication with the PCM or GWM. REFER to: Communications Network - 2.0L Duratec - Hybrid (96kW/130PS) . Using a diagnostic scan tool, CLEAR the SOBDMC Diagnostic Trouble Codes (DTCs).

  2. I2 CHECK THE ABS (ANTI-LOCK BRAKE SYSTEM) MODULE CONTINUOUS MEMORY DIAGNOSTIC TROUBLE CODES (CMDTCS)

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

    • Clear the Diagnostic Trouble Codes (DTCs).

    • Ignition OFF.

    • Ignition ON.

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

    • Record the ABS module Diagnostic Trouble Codes (DTCs).

    Is DTC P193B:xx or U0100:xx 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. Using a diagnostic scan tool, CLEAR the SOBDMC Diagnostic Trouble Codes (DTCs).

  3. I3 REVIEW THE RECORDED ABS (ANTI-LOCK BRAKE SYSTEM) MODULE SELF-TEST DIAGNOSTIC TROUBLE CODES (DTCS)

    • Check the recorded Diagnostic Trouble Codes (DTCs) from the ABS self-test.

    Was DTC U3003:16 or U3003:17 recorded? 

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

  4. I4 RETRIEVE ANY DIAGNOSTIC TROUBLE CODES (DTCS) FROM THE GWM (GATEWAY MODULE A) SELF-TEST

    • 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 - 2.0L Duratec - Hybrid (96kW/130PS) .
    No  GO to  I5

  5. I5 RETRIEVE ANY DIAGNOSTIC TROUBLE CODES (DTCS) FROM THE PCM (POWERTRAIN CONTROL MODULE) SELF-TEST

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

    Are any Diagnostic Trouble Codes (DTCs) set in the PCM? 

    Yes  DIAGNOSE the PCM Diagnostic Trouble Codes (DTCs). REFER to: Electronic Engine Controls . Using a diagnostic scan tool, CLEAR the SOBDMC Diagnostic Trouble Codes (DTCs).
    No  GO to  I6

  6. I6 CHECK FOR OTHER CAUSES OF COMMUNICATION NETWORK CONCERN

    NOTE: If new modules were installed prior to the DTC being set, the module configuration can 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 or ABS module. If recent service history is found:

      • verify the correct replacement module was installed.

        • HVBOM may be used to verify correct part fitment.

      • verify the configuration of replacement module was correct.

        • re-configure the 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  I7
    No  The system is operating correctly at this time. The concern may have been due to incorrect parts replacement procedures or incorrect module configuration.

  7. I7 CHECK FOR DTC (DIAGNOSTIC TROUBLE CODE) P193B:XX OR U0100:XX SET IN OTHER MODULES

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

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

    Is DTC P193B:xx or U0100:xx set in 1 or more modules in addition to the ABS module? 

    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: Powertrain Control Module (PCM) . Using a diagnostic scan tool, CLEAR the SOBDMC Diagnostic Trouble Codes (DTCs).
    No  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 ABS module. REFER to: Anti-Lock Brake System (ABS) Module . Using a diagnostic scan tool, CLEAR the SOBDMC Diagnostic Trouble Codes (DTCs).
