Change Oil Soon Indicator

The Powertrain Control Module (PCM) determines the amount of oil life from various sensors and inputs within the engine control system. The PCM performs the following functions:
^ Calculates the oil life.
^ Sends the calculation to the instrument cluster via the class II serial data bus.

When the PCM determines that an oil life of 0% is present, the PCM informs the driver by turning on the CHANGE OIL SOON indicator. After an oil change, the light may be reset by performing the following procedures:
^ Turn 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 flashes 2 times indicating the system is reset. If the light comes on and stays on for 5 seconds, the system did not reset. The system will need to be reset again.

If the vehicle is equipped using an up-level cluster including a Driver Information Display (DID), the system may be reset by pressing the DID RESET button for approximately 5 seconds while viewing the oil life display on the DIC.
