Check Oil Level

WARNING: This page is about a different car, the 2007 Hummer H2. However, it is still accessible from the selected car via links, so may be relevant.

The instrument panel cluster (IPC) illuminates the CHECK OIL LEVEL message in the driver information center (DIC) when the powertrain control module (PCM) detects a low engine oil level condition. The PCM only monitors the oil level switch signal circuit for a brief period between key on and ignition crank. The IPC receives a class 2 message from the PCM requesting illumination.
