Suspension Control ( Automatic - Electronic ): Description and Operation

Vehicle Dynamic Suspension

The vehicle dynamic suspension consists of the following components:

- Air compressor
- Air spring
- Air suspension height sensor (rotary type)
- Air suspension switch
- Air tubes
- Compressor drier
- Solenoid valve
- Vehicle Dynamics Module (VDM)
- Wheel studs

The vehicle dynamic suspension system uses an electric pump to pressurize air springs which replace the traditional coil springs. The programmed vehicle ride height is controlled by a VDM which receives a signal from suspension mounted height sensors. The purpose of the vehicle dynamic system is to provide smooth ride quality and a self-leveling suspension. A switch allows for the system to be turned ON or OFF.
