Pinpoint Test V: The Oil Change Minder Indicator Is Never/Always On

Normal Operation

The oil change minder indicator informs the driver that the vehicle requires an oil change. The Instrument Panel Cluster (IPC) receives the oil change minder indicator request from the PCM over the High Speed Controller Area Network (HS-CAN) communication bus. When the PCM has determined that the criteria for vehicle mileage or length of time has been met, the PCM sends a request to the IPC (Instrument Panel Cluster) to illuminate the oil change minder indicator.

If the oil change minder indicator request is missing or if the data is deemed invalid for less than 5 seconds, the oil change minder indicator remains in the last indication mode (on or off) based on the last known good request received. If the oil change minder indicator request is missing for more than 5 seconds, the IPC (Instrument Panel Cluster) sets DTC U0100:00 in continuous memory and defaults the oil change minder indicator off.

NOTE: If DTC U0100:00 sets in the IPC (Instrument Panel Cluster), other observable symptoms may be an inoperative speedometer, tachometer or odometer.

This pinpoint test is intended to diagnose the following:

- PCM

- IPC (Instrument Panel Cluster)
