Height Sensor:

4. Disconnect the link from the height sensor arm and manually move the arm up.
5. Listen for the air compressor to operate. There should be a 13-27 second delay before the compressor turns on. When the shock absorber bladder fills, move the height sensor down. This should stop the compressor.
6. Listen for the shocks to deflate. There should be a 13-27 second delay before the shocks begin to deflate.
- If the compressor does not turn on and off properly, replace the height sensor.
