Height Sensor Operational Test
- Cycle ignition switch to the "ON" position. Raise vehicle on hoist. Ensure axle housing is supported as close to ride height specification as possible. Check all wiring for good connections. Disconnect link from height sensor arm.
- Move sensor arm upward. After a 13-27 second delay, the compressor should run and shock absorbers should start to inflate. As soon as shock absorber air boots fill, stop compressor by moving sensor arm down.
- Move sensor arm below position where compressor stopped running. There should be a delay of 13-27 seconds before shock absorbers start to deflate and vehicle lowers. Replace height sensor if it does not function correctly.
