Oil Change Reminder Lamp: Description and Operation

Oil Change Minder

NOTE: On early build vehicles, the PCM uses time and distance calculations stored in Keep Alive Memory (KAM) in the PCM to help determine the oil change minder status. If the PCM KAM is reset or lost for any reason (battery disconnect, PCM disconnect or dead battery), the oil change minder is disabled and the oil life reset procedure needs to be carried out through the message center to re-enable the oil minder function.

The message center provides an oil change minder to inform the driver that an oil change is required. The duration of the interval between oil changes is calculated in the PCM based an a maximum mileage of 16,093 km (10,000 miles) or 1 year for normal driving. The PCM calculates and provides an oil life status message to the IPC. The IPC further converts the remaining oil life using the driver's configured oil life start value and displays the oil life percentage, indicating the remaining oil life. The oil change minder can be reset at any time by the driver. Refer to Message Center Configuration Service and Repair.
