Pinpoint Test H: The Odometer Is Inoperative
Normal Operation
The Instrument Cluster (IC) receives the odometer rolling count data from the PCM over the High Speed Controller Area Network (HS-CAN) communication bus. The IC monitors the odometer rolling count input from the PCM and commands the odometer with a display in the integrated display area (base IC) or the message center display (message center IC).
NOTE: If DTC U0100 is set in the IC, other observable symptoms may be an inoperative speedometer, tachometer, temperature gauge.
If the IC does not receive the odometer rolling count data from the PCM for more than 5 seconds, the IC sets DTC U0100 in continuous memory and defaults the odometer display to all dashes (-----). If the odometer rolling count data is deemed invalid by the IC, the IC sets DTC U2023 and defaults the odometer display to all dashes (-----).
- DTC B2143 (NVM Memory Failure) - is a continuous and on-demand DTC that sets if the IC Non-Volatile Memory (NVM) is corrupted. If the IC determines the Non-Volatile Memory (NVM) to be corrupt, the IC sets DTC B2143 and displays ERROR in the integrated display area (base IC) or message center display (message center IC).
This pinpoint test is intended to diagnose the following:
- PCM concern
- IC
