SECTION: 204-06

Suspension Warning Lamp Illuminated - Diagnostic & Repair Procedure
AFFECTED VEHICLE RANGE:
Range Rover Sport (LS)
Model Year:
2006-2013
VIN:
6A901924-DA814822

MARKETS:
NAS

CONDITION SUMMARY:
Situation: The Dynamic Response system red warning lamp may be illuminated on the Instrument Cluster and
Diagnostic Trouble Codes (DTC) C1119-62, C1119-09, and/or C1B11-62 may be stored, possibly indicating
system contamination.
This Technical Bulletin provides a process for Retailers to correctly diagnose Dynamic Response system
contamination, to identify if an actuator has failed, and to determine which parts may require replacement. A
flushing procedure is provided to clean the affected parts that do not need to be replaced and ensure that the
issue does not re-occur.
Action: Should a customer express concern, use SDD to establish which actuator is at fault and carry out the
flush and repair procedure by following the Service Instruction outlined below.

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 righthand 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: 20406).
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.
Disconnect the right-hand Mass Air Flow (MAF)

sensor electrical connectors.

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

http://topix.landrover.jlrint.com/topix/service/document/492703

8/26/2014

Page 6 of 12

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.

required.
27. Install the fluid reservoir.

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.

sensor electrical connectors.

30.

NOTE: It is not necessary to perform this step if the valve block or pump has been replaced.

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 ¾ 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.
Raise and support the vehicle (see TOPIx Workshop Manual, section: 100-02).
