Pinpoint Test J: The Odometer Is Inoperative: Notes

Pinpoint Test J: The Odometer Is Inoperative 

Normal Operation

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 (-----).
