Pinpoint Test H: The Odometer Is Inoperative
- Normal Operation and Fault Conditions
See Odometer. REFER to: Instrument Panel Cluster (IPC) - System Operation and Component Description .
If the odometer count message is missing from the PCM through the GWM 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
- GWM
- PCM
- IPC
- H1 CHECK FOR CORRUPTED NON-VOLATILE MEMORY (NVM)
- Ignition ON.
- Observe the message center display area.
Does the odometer display ERROR?
Yes GO to H4 No GO to H2 - H2 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 IPC DTC Chart. Refer to Diagnostic Trouble Code (DTC) Chart . No GO to H3 - H3 CHECK THE GWM (GATEWAY MODULE A) DIAGNOSTIC TROUBLE CODES (DTCS)
- Using a diagnostic scan tool, check the GWM Continuous Memory Diagnostic Trouble Codes (DTCs).
Are any Diagnostic Trouble Codes (DTCs) recorded?
Yes REFER to: Communications Network . No DIAGNOSE all PCM Diagnostic Trouble Codes (DTCs). REFER to the appropriate Electronic Engine Controls article. - H4 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.
