Normal Operation
The air suspension on/off status is sent from the air suspension module to the instrument cluster over the high speed controller area network (HS-CAN) communication bus lines. When the RESET button is pressed, the instrument cluster sends a query to the air suspension module, requesting a system status. The air suspension module responds to the instrument cluster with the status of the system, either on or off. If the return status message is missing or corrupted, the instrument cluster does not display the brackets around either the ON or OFF selection.

Possible Causes
- Instrument cluster configuration
- Air suspension system
- Air suspension module
- Instrument cluster
