Pinpoint Test F: The Odometer Is Inoperative

  1. Normal Operation and Fault Conditions 

    See Odometer. REFER to: Message Center - System Operation and Component Description .

    If the odometer count message is missing from the PCM for 5 seconds or longer, the IPC defaults the odometer display to all dashes (------).

    If the odometer count message is deemed invalid by the IPC, the IPC defaults the odometer display to all dashes (------). If the NVM becomes corrupted or if any NVM failure occurs, odometer displays ERROR.

    Possible Sources 

    • Communication concern
    • PCM concern
    • GWM concern
    • IPC

  2. F1 CHECK FOR CORRUPTED NON-VOLATILE MEMORY (NVM)

    • Ignition ON.

    • Observe the message center display area.

    Does the odometer display ERROR? 

    Yes  INSTALL a new IPC. REFER to: Instrument Panel Cluster (IPC) .
    No  GO to  F2

  3. F2 PERFORM THE IPC (INSTRUMENT PANEL CLUSTER) SELF-TEST

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

    Are any Diagnostic Trouble Codes (DTCs) recorded? 

    Yes  REFER to the Diagnostic Trouble Code (DTC) Chart .
    No  GO to  F3

  4. F3 PERFORM THE PCM (POWERTRAIN CONTROL MODULE) KOEO (KEY ON, ENGINE OFF) SELF-TEST

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

    Are any Diagnostic Trouble Codes (DTCs) recorded? 

    Yes  REFER to the Master DTC Chart.
    No  GO to  F4

  5. F4 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) recorded? 

    Yes  REFER to: Controller Area Network (CAN) Module Communications Network .
    No  GO to  F5

  6. F5 CHECK FOR CORRECT IPC (INSTRUMENT PANEL CLUSTER) OPERATION

    • Ignition OFF.

    • Disconnect and inspect the IPC 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 IPC 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 IPC. REFER to: Instrument Panel Cluster (IPC) .
    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.
