Ride Height Adjustments

Ride Height Adjustments

Service Repair No - 60.90.03

Special Service Tools























CAUTION: Make sure the wheels and tires, tie rod ends, suspension joints and wheel bearings are free from damage, wear and free play.

CAUTION: Make sure the tire pressures are within specification.

CAUTION: Make sure there are no heavy objects in the vehicle.

CAUTION: The ride height must be measured with the vehicle weight supported by the suspension.

CAUTION: With the engine running and all vehicle doors closed, make sure the air suspension is functioning and the vehicle height can be raised and lowered using the air suspension switch.

CAUTION: Drive the vehicle on to a flat, level surface.

CAUTION: Make sure the steering is in the straight ahead position.

NOTE: This procedure must be carried out after replacement of the air suspension control module or height sensor link arm, removal or replacement of the front or rear upper arms or the height sensor. The ride height does not need calibration after removal or replacement of the front or rear air springs or shock absorbers.

1. Using the Land Rover approved diagnostic system, carry out the ride height adjustments.

2. CAUTION: The ride height measurements are made between the vehicle lower suspension arm fixings and the flat, level surface. If the ride height calibration procedure is carried out on a vehicle lift, the measurements must be made to a position at the same level as the vehicle lift platform.

CAUTION: Make sure the vehicle is not moved once it has been positioned to take measurements.

Position the vehicle on a calibrated, level surface.





3. Check the tie rod ends, suspension joints, wheel bearings and wheels and tires for damage, wear and free play.
^ Adjust or repair any worn, damaged or incorrectly adjusted components.

4. Check and adjust tire pressures.
5. Mark the position of the floor to wheel location on both left-hand wheels and tires.

6. CAUTION: Set the ride height to NORMAL and wait until the system stops adjusting. This is indicated by the NORMAL height symbol on the air suspension switch being illuminated and all other symbols being extinguished.

Set the air suspension ride height switch to NORMAL position.
7. Connect IDS to the vehicle data link connector.
^ Connect the vehicle data link cable into the vehicle communications module.
^ Connect the IDS LISB Lead into the vehicle communications module.
^ Connect the data link cable to the data link connector.
^ Connect the IDS LISB lead to the IDS LISB port.

8. CAUTION: Make sure the ignition switch is turned off, the park brake is on and the selector lever is in park.

NOTE: IDS already loaded with the latest issue of software.

Switch IDS on and navigate to the VIN input screen.
9. Enter the vehicle identification number (VIN) and navigate to the vehicle configuration menu.
^ Select setup and configuration.
^ Select air suspension height calibration and read all warnings and cautions.

10. Once in the suspension height measurement screen use the special tools to measure and record the height setting from each wheel center to the calibrated surface.





11. Using the special tool, measure and record the height setting from each front lower arm front bolt head to the calibrated level surface.





12. Using the special tool, measure and record the height setting from each rear lower arm rear bolt head to the calibrated level surface.





13. CAUTION: IDS will now cause the vehicle height to change.

Using IDS, load the new ride height calibration to the vehicle.
^ Move the vehicle forwards and backwards to settle the suspension.
14. Once the vehicle has settled at normal ride height, using the special tools repeat the vehicle ride height measurements.

15. CAUTION: IDS will now cause the vehicle height to change.

Load the second set of ride height measurements taken from the vehicle to IDS.
^ Move the vehicle forwards and backwards to settle the suspension.

16. Once the vehicle has settled at normal ride height, using the special tools repeat the vehicle ride height measurements.

17. CAUTION: IDS will now cause the vehicle height to change.

Load the third set of ride height measurements taken from the vehicle to IDS.
^ Move the vehicle forwards and backwards to settle the suspension.

18. After successful calibration of the air suspension switch off IDS and return to its original position.
