Oil Change Minder

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 and varies due to driving conditions. The PCM stores the oil life data in NVRAM. If the battery is dead, the PCM is disconnected, reflashed or the KAM is reset, the oil life settings remain in the PCM and display the remaining oil life once the vehicle is restored to normal operation. The PCM assumes a base mileage of 16, 090 km (10, 000 mi) or 1 year for normal driving. However, this number is adjusted down for conditions such as high engine temperature, high engine rpm, use of flex fuel and possibly low oil level. The PCM calculates and provides an engine service indication message to the BCM. The BCM in turn provides the engine service indication message to the IPC.

Refer to OIL LIFE RESET  to reset the oil life.
