Oil Pressure Indicator

The Oil Pressure indicator will be illuminated when the PCM transmits a class 2 message to the BCM indicating that there is a low oil pressure condition. The BCM will then command the oil pressure indicator ON over the SPI bus to the instrument cluster. In the event of a loss of class 2 serial data, the oil pressure indicator will not illuminate unless the indicator was illuminated when the event occurred. The indicator will remain in its current state for the ignition cycle when the loss occurred. In the event of an SPI data link failure, the oil pressure indicator will not illuminate unless the indicator was illuminated prior to the SPI data link failure.
