Height Sensor Operational Test

  1. Turn ignition off and then on to reset height sensor timing circuit. Raise and support vehicle. Using jack stands, raise rear suspension arms until rear riding height is as specified. See REAR RIDING HEIGHT ADJUSTMENT  under ADJUSTMENTS.
  2. Disconnect link from height sensor metal arm. Ensure height sensor connector and ground wire connection are secure. Move height sensor arm assembly upward. After 17-27 seconds, compressor should turn on and struts should start to inflate.
  3. As soon as struts start to inflate, move height sensor arm assembly downward until compressor stops. Continue to move height sensor arm assembly downward past area where compressor stopped. After 17-27 second delay, struts should start to deflate. If system operates as described, height sensor is okay.
