System Components

MAJOR COMPONENTS
The air suspension system includes the following major components:
^ Air compressor to supply air to the air springs (part of rear spring and shock absorber assemblies)
^ Rear spring and shock absorber at each rear corner of the vehicle
^ Two rear linear air suspension height sensors: to maintain the vehicle at the proper ride height; only LH rear height sensor is used for air suspension.
^ Dual-mode rear shock absorber assemblies with internal actuator.

DYNAMICS CONTROL MODULE
All system functions are controlled by vehicle dynamics control module. This control module receives inputs from several different sources. These inputs include:
^ Vehicle speed via multiplex communication network.
^ Ignition switch position.
^ Door position via multiplex communication network.
^ Height sensor position.
^ Air suspension service switch.
^ Engine rpm via multiplex communication network.
^ Ride and steering personality settings via multiplex communications network.
