Test D: The Odometer Is Inoperative

PINPOINT TEST D: THE ODOMETER IS INOPERATIVE

Normal Operation
The odometer is controlled by a rolling count signal sent from the PCM to the instrument cluster (IC) over the high speed controller area network (HS-CAN) bus lines. The instrument cluster (IC) interprets the signal sent from the PCM and displays the current mileage on the odometer liquid crystal display (LCD). The instrument cluster (IC) sets DTC U0100 in continuous memory if the instrument cluster (IC) fails to receive the odometer rolling count data from the PCM and the odometer displays ------.

- DTC B2143 (NVM Memory Failure) - sets if the instrument cluster (IC) detects a nonvolatile memory failure during its self-test sequence.

This pinpoint test is intended to diagnose the following:
- PCM
- Instrument cluster (IC)
