situations, to release the electric park brake. All calibration of the
parking brake system will be lost, and the parking brake will need to be
re-calibrated to function correctly.


NOTE: The tools shown must only be used in the event of an
emergency.
Remove the RH loadspace trim panel.
For additional information, refer to: Loadspace Trim Panel RH (501-05 Interior Trim and Ornamentation, Removal and Installation). www.JagDocs.com

3. WARNING: Failure to follow this instruction may result in a
diagnostic trouble code (DTC) being generated.

Disconnect the 2 electrical connectors from the parking
brake module, in the sequence illustrated.




















4. NOTE: Some variation in the illustrations may occur,
but the essential information is always correct.

Connect the special tool to the parking brake module.










5. Release the parking brake cable tension.
An audible 'click', signals complete parking brake cable
tension release.

2. CAUTION: Make sure the wiring harness is correctly routed
to avoid contact with the halfshaft. Failure to follow this
instruction may result in damage to the component.












3. CAUTION: Calibrate the electric park brake using Jaguar approved
diagnostic system. If the Jaguar approved diagnostic system is not
available disconnect the battery for approximately 30 seconds, the
vehicle will then prompt the driver to carry out the calibration procedure
as per the vehicle hand book on re-connection.

Anti-Lock Brake System System Operation

ABS controls the speed of all road wheels to ensure optimum wheel slip when braking at the adhesion limit. The wheels are prevented from locking to retain effective steering control of the vehicle.

The brake pressures are modulated separately for each wheel. Rear brake pressures are controlled to maintain rear stability on
split friction surfaces.

Dynamic Stability Control

DSC (dynamic stability control) uses brakes and powertrain torque control to assist in maintaining the yaw stability of the
vehicle. While the ignition is energized the DSC function is permanently enabled, unless selected off using the DSC switch.

DSC enhances driving safety in abrupt maneuvers and in under-steer or over-steer situations that may occur in a bend. The
ABS module monitors the yaw rate and lateral acceleration of the vehicle, steering input and individual wheel speeds, then selectively applies individual brakes and signals for powertrain torque adjustments to reduce under-steer or over-steer
conditions.
In general:

In an under-steer situation the inner wheels are braked to counteract the yaw movement towards the outer edge of the
bend.
In an over-steer situation the outer wheels are braked to prevent the rear end of the vehicle from pushing towards the
outer edge of the bend.

The ABS module monitors the tracking stability of the vehicle using inputs from the wheel speed sensors, the steering angle sensor, and the yaw rate and lateral acceleration sensor. The tracking stability is compared with stored target data. Whenever
the tracking stability deviates from the target data, the ABS module intervenes by applying the appropriate control strategy. The following interactions occur in an intervention situation:

High speed CAN signal to the ECM, to reduce engine torque. Application of braking to the appropriate corner of the vehicle.
Trac DSC

TracDSC is an alternative setting of DSC with reduced system interventions. With TracDSC engaged, traction may be somewhat
increased, although stability may be reduced compared to normal DSC. TracDSC is intended for use only on dry tarmac, by
suitably experienced drivers and should not be selected for other surfaces or by drivers with insufficient skill and training to
operate the vehicle safely with the TracDSC function engaged.

The less restrictive TracDSC setting may be preferred, for example, by expert drivers engaged in high performance driving on
dry Tarmac surfaces such as tracks and circuits.
Switching between DSC and Trac DSC:

With the control valve (7) OPEN and the engine idling, the following system pressures may be checked:

During turning when static (dry parking pressure).
When the steering is held on full lock (maximum system pressure or pressure relief).
With the steering at rest (idle pressure or back pressure).
CAUTIONS:


To avoid excessive heating of the power steering pump when checking the pressure, do not close the valve for more than
5 seconds maximum.


When checking the pump pressure DO NOT drive the vehicle with the test equipment installed.

With the control valve (7) CLOSED the power steering pump maximum output pressure can be checked.

Removing Test Equipment

To remove the test equipment:

Install a hose clamp on the reservoir to power steering pump hose.
Removing the test equipment is a reversal of the installation instructions.
Install a new 'O' ring seal (9) to the power steering pump high pressure outlet to hose connection.
Install the original hose to the power steering pump.
Remove the clamp from the reservoir to the power steering pump hose.
Top-up the reservoir fluid.
Bleed the power steering system.
REFER to: Power Steering System Bleeding (211-00 Steering System - General Information, General Procedures).
