    I have a 2006 Chevrolet Uplander engine capacity 3500 cc , and six months ago I broke the sensor leveling of the rear air suspension. For a period drove without a rear suspension system works. Recently put on a new sensor level but the car does not give me relief provides.
    When I turn on the car has run a few seconds the rear suspension system and vehicle rises up about one inches.
    When I'm driving and passing over the bump in the road I do feel the hit like before as if that truck without active suspension system.
    I'd be happy if someone could explain to me where the problem
    And is required to calibrate the computer

    If you run a "self-leveling" shock system without the compressor for any amount of time and load it down once... your shocks are going to be destroyed. Pull one off and I'll bet you find it's now worthless. If your compressor is running for about 115 seconds and shutting off every time you turn on the key... then your shocks are bad and your compressor is protecting itself from overheating.
