Function

The air suspension control module receives the vehicle speed signal from the instrument cluster. If the speed is higher than 6 km/h, the control module switches to automatic mode and manual mode is disabled.

Changes in level due to different loading conditions and other force effects such as braking are recognized and processed by the control module.

The respective different functions of the air suspension when driving and braking are then executed by the control module.
