Ride Height Sensor: Testing and Inspection
CAUTION: When diagnostic procedures require that vehicle be raised on a hoist, it is important that the rear axle assembly remains in
the normal trim height position at all times. When a frame contact hoist is used, two additional jack stands should be used to support the
rear axle or control arms in the normal trim height position.
1.
Turn ignition Off, then On. This will reset height sensor timer circuits.
2.
Raise vehicle on hoist. Ensure rear wheels or axle housing are supported and that vehicle is at proper trim height.
3.
Disconnect link from height sensor arm, then ensure sensor wiring and harness ground are connected properly.
4.
Move sensor arm upward. There should be a delay of 8-15 seconds before compressor turns on and shocks start to inflate. As soon as shocks start
to fill, stop compressor by moving sensor arm down.
5.
Move sensor arm down below position where compressor stopped. There should be a delay of 8-15 seconds before shocks start to deflate and
vehicle lowers.
