Ride Height Sensor: Service and Repair
Suspension Height SensorRemoval
NOTE: Vehicles built before December 2003 have four suspension height sensors which are mounted on the front and rear subframe assemblies, two front and two rear. Vehicles built after December 2003 have only three (the right front sensor being deleted), although the functionality of the system remains the same. There may be some early vehicles which will have four sensors fitted, but which have the three-sensor module, making the right front sensor redundant To confirm the level of equipment read the module part number from the special applications menu in configuration on the Jaguar approved diagnostic system. Part numbers before 'BJ' are four sensor, while 'BJ' and after are three sensor. if the Jaguar approved diagnostic system is not available, remove the rear seat and sound deadening and read the part number from the module.
NOTE: The later module can be fitted in place of the four sensor module, but the right front sensor must be left in place, even though the system will not use it

1. Remove the wheel and tire assembles.
2. CAUTION: Do not spray solvents or cleaning agents inside the height sensor. Failure to follow this instruction may result in damage to the vehicle.
CAUTION: Make sure the height sensor is thoroughly cleaned prior to disassembly.
NOTE: Front shown, rear similar.
Disconnect the front air suspension height sensor electrical connector.
3. NOTE: This step is for front air suspension height sensors only.
Detach the wheel speed sensor harness.
4. NOTE: Front shown, rear similar.
Detach the front air suspension height sensor link rod.
5. NOTE: Front shown, rear similar.
Remove the front air suspension height sensor.
Remove the front air suspension height sensor retaining bolts.
Installation
1. To install, reverse the removal procedure.
Tighten to 20 Nm.
2. NOTE: To aid installation of the electrical connector, apply a small amount of silicone based oil or grease to the connector seal.
NOTE: Make sure the electrical connector latch is fully secured to the sensor.
Connect the front air suspension height sensor electrical connector.
3. Re-calibrate the suspension height sensor using the Jaguar approved diagnostic system.
