Low Oil Indicator

The low oil indicator is controlled by either of the following components:
^ The powertrain control module (PCM)
^ The instrument cluster

The PCM receives oil level information from the engine oil level switch. When a low engine oil condition exists, the PCM sends a Class 2 message through circuit 1036 to the instrument cluster in order to turn on the low oil indicator.

The instrument cluster turns the low oil indicator on for approximately 3 Seconds at bulb test.
