Cruise Indicator

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

With the cruise control engaged, the PCM receives an input signal from the cruise control module. The PCM sends a class 2 serial data message to the BCM. This condition sends a SPI data message to the instrument cluster in order to illuminate the cruise indicator.

In the event of a SPI data loss, the cruise indicator will not illuminate unless the cruise indicator was illuminated prior to the SPI data line failure.
