PINPOINT TEST I : The Odometer Is Inoperative: Notes

Diagnostic Overview

Refer to Instrument Panel Cluster (IPC) , Odometer.

NOTE: If DTC U0100:00 sets in the IPC, other observable symptoms can be an inoperative speedometer, tachometer or temperature gauge.

Normal Operation and Fault Conditions

If the odometer count message is missing for 5 seconds or less, the IPC defaults the odometer to the last display, based upon the last known good odometer rolling count message.

If the IPC does not receive the odometer rolling count data from the PCM for more than 5 seconds, the IPC sets DTC U0100:00 in continuous memory and defaults the odometer display to all dashes (-----).

If the odometer count message is deemed invalid by the IPC, the IPC sets DTC U0401:00 and defaults the odometer display to all dashes (-----). If the NVM becomes corrupted or if any NVM failure occurs, the IPC sets DTC U3000:44 and displays ERROR in the message center display.
