Test G: The CHECK AIR SUSPENSION Or AIR SUSPENSION OFF Warning Is Inoperative

PINPOINT TEST G: THE CHECK AIR SUSPENSION OR AIR SUSPENSION OFF WARNING IS INOPERATIVE

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

This pinpoint test is intended to diagnose the following:
- Instrument cluster (IC) configuration
- Air suspension system
- VDM
- Instrument cluster (IC)
