Height Sensor

Fig. 1: Vehicle height sensor harness terminal identification

Fig. 2: Check for continuity at these positions

Disconnect the height sensor wire harness at the air shock.
Disconnect air shock line and bleed air from the shock.
Using an ohmmeter, check for continuity between the terminals of the height sensor side of the wire harness.
While using the ohmmeter, compress and extend the shock, and observe when there is continuity.
If not as specified replace or repair the height sensor.

Fig. 4: Height sensor and air line disconnected from the shock assembly

Disconnect the air line from the solenoid valve.
Disconnect the height control wire harness.
With shock compressed, check that the resistance between terminal 2 and 4 is a minimum of 1 megohm.
With the shock expanded check that the resistance between terminal 2 and 4 is 0 ohms.
With the shock compressed, check that the resistance between terminal 2 and 3 is 0 ohms.
With the shock expanded, check that the resistance between terminal 2 and 3 is a minimum of 1 megohm.
If not as specified, replace the height sensor.
