Level Sensor

A user must begin the height sensor replacement by disconnecting the ELC/TRAILER fuse before conducting diagnostic testing after restoring the sensor. Start by raising and supporting the vehicle and disconnection of the ride height sensor electrical connector. To remove the ride height sensor, start with unfastening the ride height sensor link from the sensor arm ball stud and then remove the ride height sensor bracket bolts before taking out the ride height sensor from the vehicle premises. Install the ride height sensor on the vehicle while following the Fastener Notice and tighten the ride height sensor bracket bolts to 85 N.m (63 lb ft). Reconnect the sensor electrical connector after connecting the sensor link to the ball stud of the sensor arm. Complete the process by checking the diagnostic system while placing the vehicle in its normal position and then reinstalling the ELC/TRAILER fuse. Control Module References contain all information about programming and setup procedures.

You must remove the ELC/TRAILER fuse before starting replacement of the Ride Height Sensor. Fitting the height sensor requires performing an active diagnostic system assessment. Raise and support the vehicle. Detach the ride height sensor electrical connector and remove its link from the ball stud located on the sensor arm. Begin by removing the ride height sensor bracket bolts from the vehicle. Finish the removal with the sensor. Install the ride height sensor on the vehicle by fixing the height sensor bracket bolts before tightening them to 85 Nm (63 ft. lbs.). Secure the ride height sensor link onto the ball stud of the sensor arm before connecting the ride height sensor electrical connector. After carrying out a diagnostic system check, you must lower the vehicle while re-installing the ELC/TRAILER fuse.

The first step to replace the Ride Height Sensor (Twist Axle) requires the ELC/TRAILER fuse removal followed by raising and supporting the vehicle. The first step involves disconnecting the Ride Height sensor connector before removing its link from the ball stud. Begin by removing the Ride Height sensor bracket's bolts or screws after taking them out. Remove the Ride Height sensor together with its bracket from the vehicle. The Ride Height sensor along with its bracket need to be returned to their original position on the vehicle and the height sensor bolts/screws should be fastened to 12 N.m (106 lb in). Begin by attaching the Ride Height sensor link to the ball stud followed by connecting its connector to the system. Then lower the vehicle frame before placing back the ELC/TRAILER fuse into its socket.

The first step to replace the Ride Height Sensor involves erasing the ELC/TRAILER fuse from its port. A diagnostic system check must always be performed before installing a new height sensor. After that raise the vehicle and use a support system. Disconnect the ride height sensor electrical connector before removing its link from the ball stud on the sensor arm. The ride height sensor bracket bolts must be removed so the sensor can be taken out of the vehicle. After putting the ride height sensor into position install its height sensor bracket bolts while making them tight to 85 N.m (63 lb ft). The sensor link for the ride height sensor and the ride height sensor electrical connector need to be reconnected after attaching them to the sensor arm ball stud. Lower the vehicle then install the ELC/TRAILER fuse. You should complete a diagnostic system check while consulting Control Module References for instructions about programming and setup.

Disconnect the ALC sensor connector and remove the ALC sensor link from the ball stud.

Remove the ELC/TRAILER fuse and ensure a diagnostic system check is performed after the height sensor replacement.
