Level Sensor, Rear Passenger Side

A replacement of the air spring leveling sensor requires removing the air suspension system fuse first to avoid calibration problems. Level the vehicle by parking on flat ground and monitor each tire pressure against the vehicle certification label specifications. Examine all components of the air suspension system to identify damages and defects. Livestock the vehicle while you remove the rear tire along with wheels from the vehicle. The rear axle needs to maintain its proper d height according to trim height specifications after receiving support. Unplug the electrical connector as well as remove the sensor mounting bolts to take out the sensor after separating its link from the Control Arm. To install the sensor link must be attached to the upper Control Arm followed by fastening the sensor to the frame with bolts tightened to 8 nm (71 inch lbs.) and perform a sensor alignment test before removing the locating pin. Connect the electrical connector then remove the rear axle support before reattaching the rear tire with its wheels. Finally raise the vehicle before inserting the air suspension system fuse. You should turn on the vehicle and operate it for 1 minute to prove the air spring leveling system operative before conducting a d height measurement according to the trim height inspection procedure.

Start the vehicle and run it for about 1 minute, then check the D height as per the Trim Height Inspection Procedure.

Attach the air spring level sensor link to the upper control arm, ensuring the sensor is properly aligned before removing the locating pin. Install the sensor to the frame mounting bolts and tighten them to 8 Nm (6 ft. lbs.), then connect the electrical connector.
