Oil Change Reminder Lamp: Description and Operation

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 (Powertrain Control Module) and varies due to driving conditions. The PCM (Powertrain Control Module) stores the oil life data in NVRAM (Non-Volatile Random Access Memory). If the battery is dead, the PCM (Powertrain Control Module) is disconnected, reflashed or the KAM (Keep Alive Memory) is reset, the oil life settings remain in the PCM (Powertrain Control Module) and display the remaining oil life once the vehicle is restored to normal operation. The PCM (Powertrain Control Module) 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 (Revolutions Per Minute), use of flex fuel and possibly low oil level. The PCM (Powertrain Control Module) calculates and provides an engine service indication message to the BCM (Body Control Module). The BCM (Body Control Module) in turn provides the engine service indication message to the IPC (Instrument Panel Cluster).
