Pinpoint Test Cy : U011D:00

  1. Normal Operation and Fault Conditions 

    REFER to: Communications Network - System Operation and Component Description .

    DTC Fault Trigger Conditions 

    DTC Description Fault Trigger Condition
    IPC U011D:00 Lost Communication With All Wheel Drive Control Module: No Sub Type Information Sets in continuous memory in the IPC if data messages received from the AWD module through the GWM are missing for 5 seconds or longer.

    Possible Sources 

    • Communication concern
    • GWM
    • AWD module
    • IPC

  2. CY1 VERIFY THE CUSTOMER CONCERN

    • Ignition ON.

    • Verify there is an observable symptom present.

    Is an observable symptom present? 

    Yes  GO to  CY2
    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.

  3. CY2 CHECK THE COMMUNICATION NETWORK

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

    Does the AWD module pass the network test? 

    Yes  GO to  CY3
    No  REFER to: Communications Network .

  4. CY3 CHECK THE IPC (INSTRUMENT PANEL CLUSTER) CONTINUOUS MEMORY DIAGNOSTIC TROUBLE CODES (CMDTCS)

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

    • Clear the Diagnostic Trouble Codes (DTCs).

    • Wait 10 seconds.

    • Repeat the IPC self-test.

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

    Yes  DIAGNOSE all non-network Diagnostic Trouble Codes (DTCs). REFER to DTC Chart: IPC .
    No  GO to  CY4

  5. CY4 PERFORM THE AWD (ALL-WHEEL DRIVE) MODULE SELF-TEST

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

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

    Yes  REFER to: Four-Wheel Drive Systems .
    No  GO to  CY5

  6. CY5 CHECK THE GWM (GATEWAY MODULE A) DIAGNOSTIC TROUBLE CODES (DTCS)

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

    Are any Diagnostic Trouble Codes (DTCs) set? 

    Yes  REFER to: Communications Network .
    No  GO to  CY6

  7. CY6 RECHECK THE IPC (INSTRUMENT PANEL CLUSTER) DIAGNOSTIC TROUBLE CODES (DTCS)

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

    • Ignition OFF.

    • Ignition ON.

    • Wait 10 seconds.

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

    • Check the IPC Diagnostic Trouble Codes (DTCs).

    Is DTC U011D:00 still present? 

    Yes  GO to  CY7
    No  The system is operating correctly at this time. The DTC may have set due to high network traffic or an intermittent fault condition.

  8. CY7 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 AWD module, GWM or IPC. If recent service history is found:

      • verify correct replacement module was installed

        • vehicle parts build 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  CY8
    No  The system is operating correctly at this time. The concern may have been due to incorrect parts replacement procedures or incorrect module configuration.

  9. CY8 CHECK FOR CORRECT AWD (ALL-WHEEL DRIVE) MODULE OPERATION

    • Ignition OFF.

    • Disconnect and inspect the AWD module connector.

    • 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 AWD module connector. Make sure it seats and latches 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, INSTALL a new AWD module. For 1.5L or 2.0L, REFER to: All-Wheel Drive (AWD) Module - 1.5L EcoBoost (132kW/180PS) - I3/2.0L EcoBoost (177kW/240PS) - MI4 . For 2.5L Hybrid, REFER to: All-Wheel Drive (AWD) Module - 2.5L Duratec - Hybrid (121kW/164PS) (BG) .
    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.
