A Land Rover-approved Midtronics Vehicle Power Supply must be connected to the vehicle battery during IDS diagnosis / module

programming. Connect the Land Rover-approved Midtronics Vehicle Power Supply to the vehicle battery.

7. Turn ignition 'ON' (engine not running).

8. NOTE: IDS must be loaded with DVD131.06 v.117 or later.

Connect the IDS to the vehicle and begin a new Symptom Driven Diagnostics (SDD) session.

9. Follow the on-screen prompts, allowing SDD to read the VIN and identify the vehicle.

10. From the Session Type selection screen, choose 'Diagnosis'.

11. Select the 'Selected Symptoms' tab, and then select:

^ Service Function

12. Select 'continue'.

13. Select the 'Recommendations' tab.

14. CAUTION: During this procedure, if SDD presents a

question regarding compressor type, always select the type/manufacturer for the compressor being fitted to the vehicle as part of this repair,

which under all circumstances should be an AMK compressor type. If unsure select 'EXIT' at this prompt and repeat this process after the facts

are known. Failure to make the correct compressor type selection will cause SDD to install incorrect software. From the Recommendations tab,

select 'Run' to perform the Air suspension - Air suspension compressor replacement function.

^ Follow all on-screen instructions to complete this task.

15. Exit the current session.

16. Disconnect the IDS and the Midtronics Vehicle Power Supply from the vehicle.
