CHECK OIL Indicator

The check oil indicator (amber) will be illuminated when the PCM completes the following functions:
^ Reads the oil level switch
^ Transmits a class 2 message to the BCM indicating that a low oil level condition exists

The BCM will then command the check oil indicator ON over the SPI interface to the instrument cluster. If the low oil level option is false, all of the class 2 activity on the part of the BCM will stop. The BCM will not send out any request for the low oil level condition command and will not issue a low oil level condition report. In the event of a loss of BCM or PCM Class 2 serial data, the check oil indicator will not illuminate unless the indicator was illuminated when the event occurred. In the event of an SPI data link failure, the check oil indicator will not illuminate unless the indicator was illuminated prior to the SPI data link failure.
