Engine Oil Low Check Level

The IPC illuminates the ENGINE OIL LOW CHECK LEVEL message in the Driver Information Center (DIC) when the Powertrain Control Module (PCM) detects low engine oil level, and the signal circuit is high. 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.
