Engineering is investigating reports of XJ (X351) ride height sensors not operating
correctly.
Cause:
The air suspension and active dynamics modules include checks of the height sensors
during vehicle usage. If there is a fault with the height sensor, wiring harness, or
connector, then a DTC will be stored. The affected ride height sensor part numbers are
C2D6859, C2D16582, C2D6857, C2D16580, C2D6858, and C2D16581.
Action:
If no DTC is logged then the height sensor does not need to be replaced.
If a ride height sensor DTC is logged (for example. DTC's C1A05-12, C1A06-14,
C1A701C, C1A03-1C, C1A06-1C etc.) please carry out the actions below:
1. Record the DTC's logged including status (Permanent, Intermittent & Historic)
2. Record when DTC's occurred and the number of occurrences.
3. For the Height Sensor(s) identified by the DTC, check that the electrical connectors
to the ride height sensors are securely latched.
4. Check the intermediate harness connectors are correctly latched eg. body to rear
subframe harness.
5. If all connections were correctly made, disconnect the affected height sensor(s) and
check to ensure there is no internal corrosion of the pins and connector - if there is
corrosion, check the wires for damage within 200mm of the connector and carry out
suitable harness repair and replace the affected height sensor.
6. Disconnect the module and affected height sensor and test wires for continuity
Note: Wires must never be probed through insulation, only direct connection
to pins should be used. On completion reconnect connectors and ensure fully
latched.
7. If checks 3-6 do not find any issues replace the height sensor only if the DTC is
recorded as either 'Permanent' or 'Intermittent'.
8. If the DTC does not meet the requirements of '7' do not replace the height sensor.
9. Clear the DTC(s) and test the vehicle to ensure the the DTC does not reoccur.
10. If the issue repeats, investigate the cause of the concern further and rectify.

11. If a ride height sensor is found to be faulty please submit an EPQR. The EPQR
should include the DTC(s) logged including the number of occurrences & times.
12. The ride height sensor is required by JLR engineering for further investigation. A
Priority Return Request will be arranged.
