Low Oil Level

The driver information center (DIC) displays CHECK OIL LEVEL when the engine control module (ECM) detects a low engine oil level condition from the engine oil level sensor/switch. The instrument panel cluster (IPC) receives a GMLAN message indicating a low engine oil level condition.

• When the Low Engine Oil Level 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 indicator or message staying on after the engine attains proper oil level.
• Before replacing the IPC because of the Low Engine Oil Level 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 indicator to turn OFF after an engine thermocycle process. Refer to GM Oil Life System Resetting .
