Oil-Life Reset

The powertrain control module (PCM) sends the oil life remaining percentage to the body control module (BCM) via a serial data message. The radio receives a serial data message from the BCM indicating the remaining oil life. The radio displays the current percentage of the GM Oil Life System as determined by the PCM. When the oil life remaining percentage drops below 10 percent, the radio 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 ENTER button for 5 seconds until the radio displays ACKNOWLEDGED.
