Air Suspension Control Module

The air suspension control module uses the medium speed CAN. The air suspension control module controls the air compressor motor (through a solid state relay) and all system solenoids. The module also provides power to front and rear height sensors on 4-wheel air suspension systems, or rear height sensors on the rear-wheel suspension systems. The module controls vehicle height adjustments by monitoring 2 height sensors, vehicle speed, a steering sensor, acceleration input, the door ajar signal, transfer case signals and the brake switch. The module also conducts all fail-safe and diagnostic strategies and contains self-test and communication software for testing the vehicle and module.
