Low Oil Level

The instrument panel cluster (IPC) displays the LOW OIL LEVEL message in the DIC when the PCM/ECM detects a low engine oil level condition and the low oil level switch signal circuit is high. The PCM/ECM monitors the signal circuit of the engine oil level switch for a brief period when the key moves from ON to START to determine the oil level. The IPC receives a class 2 message from the PCM/ECM requesting display of the LOW OIL LEVEL message in the DIC (if equipped with uplevel IPC UH8).
