Oil Life Message Center Display

The IPC  provides message center messages to inform the driver about the oil life status and when 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  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 the engine oil life percent 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.

The IPC  receives the engine oil life message and engine oil life reset request from the GWM  over the High Speed Controller Area Network 3 (HS3-CAN).
