Oil Life Remaining

Oil life left % is based on the information the DIC receives from a class 2 message from the PCM. The DIC displays the current % of the GM Oil Life System. When the oil needs changing the change engine oil indicator in the message center turns on.

When the engine oil is changed the changed engine oil indicator needs to be cleared out of the message center and the oil life left needs to be reset, refer to GM Oil Life System - Resetting. While in this mode press and hold the Set button until 100% is displayed.
