Low Oil Level Indicator

Range: ON/OFF
This data indicates what message is being sent from the BCM to the instrument cluster in order to control the low oil level indicator illumination. When the BCM is commanding the low oil level indicator to be illuminated, ON is displayed. When the BCM is commanding the low oil level indicator not to be illuminated, OFF is displayed.

The engine oil level switch is located in the engine oil pan. This switch closes to ground when the engine oil level is satisfactory. This switch sends a discrete input to the PCM that in turn sends a class 2 serial data message to the BCM. This condition sends a SPI serial data message to the instrument cluster in order to illuminate the low oil indicator level indicator.

In the event of a BCM or PCM class 2 serial data loss, the low oil level indicator will not illuminate unless the low oil level indicator was illuminated when the serial data loss occurred. In the event of a SPI data loss, the low oil level indicator will not illuminate unless the low oil level indicator was illuminated prior to the serial data loss.
