Ride Height Sensor: Description and Operation
The air suspension height sensors are connected between the frame and the anti-wind bars. The air suspension height sensors send signals to the control
module via magnets mounted in the lower slide portion of the air suspension height sensor. Movement generates a signal through two small Hall effect
switches attached to the air suspension height sensor housing. There are four possible conditions that the control module interprets from the signals:
^
Vehicle is at trim height.
^
Vehicle is below trim height.
^
Vehicle is above trim height.
^
Incorrect height information.
When the height sensors are compressed, the rear of the vehicle is being lowered and this will cause the air compressor to turn on and pump compressed
air to the air springs. When the sensor is extended, the rear of the vehicle is being raised and this will cause the air to be vented from the air springs to
lower the vehicle back to its trim height level.
