How to Replace a Ride Height Control Module

suspension system in a car

Some vehicles have adjustable suspensions. In these systems, the ride height control module commands changes in the ride height to ensure the desired front to rear suspension level. Most systems are pneumatic and the control module receives input from various sensors, such as the height sensors, vehicle speed sensors, steering angle sensor, yaw rate sensor and brake pedal switch. It then uses this information to determine control of the air compressor motor and system solenoids to raise and lower the vehicle. Common signs of failure include the illumination of the Air Ride Suspension Light, a bumpy ride, or uneven ride height.
