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.
http://topix.landrover.jlrint.com/topix/service/document/492703
8/26/2014
Page 3 of 12
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.

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':
