Suspension - Electronic Air: Description
Air suspension system incorporates rear air leveling and road calibrated suspension ride control into one system. Air leveling maintains vehicle at proper level under different load conditions. Road calibrated suspension ride control switches the shock absorbers between soft and hard damping.
System consists of front struts, rear shock absorbers, actuators, height sensors, air spring solenoids, door switches, air suspension Vehicle Dynamics Module (VDM), air suspension switch and compressor relay. See Fig 1 or Fig 2 .
On 1996 models, air springs are used on front and rear suspension. On 1997 models, air springs are only used on rear suspension and coil spring are used on front.
