Air suspension control module is located behind left center of instrument panel. Control module controls air compressor, all system solenoids, and damper motors located in each shock absorber. Control module also provides power to height sensor. Shock absorber and height adjustments are controlled by monitoring height sensor, Vehicle Speed Sensor (VSS), steering sensor, acceleration input, door ajar signal, 2 transfer case signals, brake switch and individual shock absorber feedback signals. Control module conducts all fail-safe strategies and incorporates self-diagnostic and communication capabilities.
