CHANGE OIL SOON Indicator

The Powertrain Control Module (PCM) will determine the amount of oil life from various sensors and inputs within the engine control system. Oil life is calculated by the PCM and sent to the instrument cluster via the class II serial data bus. When the PCM has determined that an oil life of 0% is present it will inform the driver by turning on the CHANGE OIL SOON indicator. After an oil change, the light can be reset by:
^ Turning the ignition switch to the RUN position (engine OFF).
^ Fully depress and release the accelerator pedal 3 times within 5 seconds.

The CHANGE OIL SOON indicator will flash 2 times indicating the system is reset. If the light comes on and stays on for 5 seconds, it did not reset. The system will need to be reset again.
^ If the vehicle is equipped with an up-level cluster including a Driver Information Center (DIC), the system may be reset by pressing the DIC RESET button for approximately 5 seconds while viewing the oil life display on the DIC.
