Air Suspension Control Module

Air suspension control module may also be referred to as simply control module or 4 Wheel Air Suspension (4WAS) module. Air suspension control module is located behind right center of instrument cluster panel. Module controls air compressor and all system solenoids. Control module also provides power to height sensors. Control module outputs are controlled by monitoring height sensors, Vehicle Speed Sensor (VSS), steering sensor, acceleration input, door ajar signal, 2 transfer case signals (on 4WD models) and brake switch feedback signals. Control module conducts all fail-safe strategies and incorporates self-diagnostic and communication capabilities.
