Oil-Life Reset

WARNING: This page is about a different car, the 2010 Pontiac G5 and 2010 Chevrolet Cobalt. However, it is still accessible from the selected car via links, so may be relevant.

The powertrain control module (PCM)/engine control module (ECM) sends the oil life remaining percentage to the body control module (BCM) via a serial data message. The driver information center (DIC) receives a serial data message from the BCM indicating the remaining oil life. The DIC displays the current percentage of the GM Oil Life System as determined by the PCM/ECM. When the oil life remaining percentage drops below 10 percent, the DIC displays CHANGE ENGINE OIL. When the engine oil is changed, reset the engine oil life in order to clear the oil life remaining percentage display. Press and hold the SET/RESET button for 5 seconds until the DIC acknowledges.

For more information on the rest of the personalization modes, refer to the Owner's Manual.
