SERVICE INSTRUCTION:
1. Connect the Jaguar Land Rover-approved Midtronics battery power supply to the vehicle battery.
2. Turn ignition ‘ON’ (engine not running).
3. Connect the Symptom Driven Diagnostics (SDD) system to the vehicle and begin a new session.
4. Follow the on-screen prompts, allowing SDD to read the VIN and identify the vehicle and initiating the data collect sequence.
5. Read and record all Diagnostic Trouble Codes (DTC).
- Follow the Service Instruction if any of the following DTC codes are present: C1119 62, C1119 09, C1B 1162.
6. CAUTION: If the Dynamic Response system reservoir is empty, pump damage is likely to have occurred.
Check the Dynamic Response system fluid level.
- If the level is correct, proceed to step 12.
- If the fluid is low, inspect system for leaks.
7. WARNING: Do not work on or under a vehicle supported only by a jack. Always support the vehicle on safety stands.
Raise and support the vehicle (see TOPIx Workshop Manual, section: 100-02).
8. Remove the engine under shield (see TOPIx Workshop Manual, section: 501-02).
9. Remove the radiator access panel.
10. Remove the right-hand splash shield.
11. Inspect the Dynamic Response system for leaks.
12. Using SDD, perform the Dynamic Response system test.
- Select ‘Special Applications’.
- Select ‘Dynamic Response system Hydraulic Control – System Test’.
- Demand 50 Bar of pressure for up to five minutes or until the primary circuit pipes (A) are hot. Check pipe temperature under right-hand wheel arch.
- If 50 bar cannot be obtained then the Pressure Control Valve (PCV) in the valve block is faulty and requires replacement with the PCV service kit (see TOPIx Workshop Manual, Section: 204-06).
- Open Directional Control Valve 1 (DCV1) and check system pressure is still 50 Bar. Hold for two minutes. If pressure has dropped by over 5 Bar, this indicates a faulty actuator.
- Open Directional Control Valve 2 (DCV2) and check system pressure is still 50 Bar. Hold for two minutes. If pressure has dropped by over 5 Bar, this indicates a faulty actuator.
13. NOTE: If the temperature comparison test is not conclusive at this stage, follow the bulletin and if condition (B) is found at step 22, the front actuator requires replacement.
Confirm which actuator is faulty.
- If all four pipes in the front wheel arch area are hot and at a similar temperature, this indicates that the front actuator is faulty. Replace the front actuator (see TOPIx Workshop Manual, section 204-06).
- If the pipes in the rear wheel arch are hot, this indicates that the rear actuator is at fault. Replace the rear actuator (see TOPIx Workshop Manual, section 204-06).
- If the pressure has dropped but there is no increase in the actuator pipes temperature (B), and rear pipes, then the valve block requires replacement (see TOPIx Workshop Manual, section 204-06). There should be a corresponding DCV fault code logged.
14. If found faulty in step 12, install a new Pressure Control Valve (PCV) service kit (see TOPIx Workshop Manual, Section: 204-06). Once complete, check the valve block and reservoir filter for signs of debris (steps 15-22). Complete bleed process. If no debris found in reservoir of valve block filter. It will not be necessary to follow the other steps shown in this procedure.
15. Remove the valve block filter (see TOPIx Workshop Manual, Section: 204-06).
16. Inspect the valve block filter.
- Check filter for signs of distortion. A distorted filter indicates excessive system pressure.
- Replace the filter.
17. Release the Dynamic Response system reservoir.
- Release the clip.
- Tie the reservoir aside.
18. Disconnect the intake air resonator.
- Release the clip.
19. Remove the right-hand air cleaner assembly.

20. Position container to collect fluid loss.
21. CAUTION: Before disconnecting or removing the components, make sure the area around the joint faces and connections is clean. Plug open connections to prevent contamination.
NOTE: Some fluid spillage is inevitable during this operation.
Remove the fluid reservoir.
- Disconnect the hoses from the fluid reservoir.
- Using a suitable tool clamp the hoses to prevent air ingress.
- Release the two clips.
22. NOTE: A small number of particles is acceptable (A). The reservoir does not require replacement.
Inspect the reservoir fluid filter for signs of contamination.
- A small number of particles is acceptable (A). The reservoir does not require replacement.
- If the filter is lightly contaminated with grey metallic looking particles, this would indicate a pump failure. Discard the reservoir if this condition is found. Proceed to next step.
- If the filter is heavily contaminated with black particles and sludge (B), this would indicate an actuator internal piston seal failure. Discard the reservoir. Proceed to step 24.
23. If required, install a new Dynamic Response system pump. It will not be necessary to change any actuator if the pump is replaced.
24. NOTE: ‘A’: all AJV8 petrol engines; ‘B’: TDV8 diesel only.
Inspect the high-pressure hose crimps for signs of movement.
- A = all AJV8 petrol engines
- B = TDV8 diesel only
25. Any pipe assembly that shows signs of movement must be replaced.
- Any gap larger than 1mm is not acceptable.
26. Replace the hose assembly as follows.
- AJV8 petrol models the hose assembly shown in graphic E93391 [see step 24 (A)] must be replaced if required.
27. Install the fluid reservoir.
- Clean the component mating faces.
- Connect the hoses.
- Install the clips.
28. Remove the hose clamps.
29. NOTE: When installing the air cleaner, make sure the locating pegs fit securely into the grommets.
Install the right-hand air cleaner assembly.
- Connect the right-hand Mass Air Flow (MAF) sensor electrical connectors.
30. NOTE: It is not necessary to perform this step if the valve block or pump has been replaced.
Remove the contaminated fluid from the actuator, without the internal leak.
- Remove both wheels and tires (see TOPIx Workshop Manual, section 204-04).
- Disconnect both the stabilizer bar links from the stabilizer bar (see TOPIx Workshop Manual, section 204-06).
- Disconnect the Dynamic Response system fluid pipes from the actuator.
- Move the actuator bar arms in opposite directions to displace the fluid. Full movement in both directions of each arm must be performed, to ensure fluid from both sides of the piston is removed.
31. Install the special tool to the Dynamic Response system reservoir.
- Completely fill the reservoir with fluid.
- Make sure the pressure regulator on the special tool is turned OFF.
- Fill the special tool bottle approximately ยพ full with fluid.
- Connect the special tool to a suitable workshop air supply.
32. WARNING: Do not work on or under a vehicle supported only by a jack. Always support the vehicle on safety stands.
