CHANGE ENGINE OIL

The driver information center (DIC) illuminates the CHANGE ENGINE OIL message when the engine control module (ECM) determines that the engine oil life is 0 percent. The ECM sends a class 2 message to the radio requesting illumination. After the oil is changed, reset the engine oil monitor. Refer to GM Oil Life System Resetting .

    • When the Low Engine Oil Level/Change Engine Oil Soon indicator displays in the IPC or DIC due to a low engine oil level condition, make sure that the ignition is turned OFF before adding or changing the oil in the vehicle. Failure to do so may result in the Low Engine Oil Level/Change Engine Oil Soon indicator or message staying on after the engine attains proper oil level.
    • Before replacing the IPC because of the Low Engine Oil Level/Change Engine Oil Soon indicator staying ON after an oil change or engine oil addition, it is necessary for the engine to undergo a thermocycle process. The IPC may not be malfunctioning but only needs the Low Engine Oil Level/Change Engine Oil Soon indicator to turn OFF after an engine thermocycle process. Refer to GM Oil Life System Resetting .
