JAGUAR XFR 2010 1.G Workshop Manual

Stoplamp Switch



The stoplamp switch is mounted on the brake pedal box. One of the prerequisites for releasing the parking brake is that the
foot brake is applied. The EPB module is able to determine the position of the footbrake by monitoring the status of the
stoplamp switch via a hardwired electrical connection.
The stoplamp switch also forms part of:
The ABS. Refer to: Anti-Lock Control - Stability Assist (206-09 Anti-Lock Control - Stability Assist, Description and Operation). The speed control system. For additional information, refer to:
Speed Control (310-03A, Description and Operation),
Speed Control (310-03B, Description and Operation),
Speed Control (310-03C, Description and Operation).

For a detailed description of the Parking Brake operation, refer to the relevant Description and Operation section of the
workshop manual. REFER to: (206-05 Parking Brake and Actuation)

Parking Brake (Description and Operation), Parking Brake (Description and Operation), Parking Brake (Description and Operation).
Parking Brake Calibration

The parking brake system must be calibrated whenever the battery has been disconnected or has been in a state of discharge,
or repairs have been carried out to the rear service or parking brake system.


NOTE: If new rear brake pads have been installed, pressure must be applied to the brake pedal a minimum of five times
prior to calibration of the parking brake system.
To calibrate the parking brake system:
1. Place gear selector lever in 'P' Park position.

2. Release parking brake cable tension to service position.
REFER to: Parking Brake Cable Tension Release (206-05 Parking Brake and Actuation, General Procedures).
3. Set the ignition status to 'ON'.
4. Apply and hold the footbrake then pull up the parking brake switch.

5. To release the parking brake, apply and hold the footbrake then release and press down the parking brake switch.

Inspection and Verification


CAUTION: Diagnosis by substitution from a donor vehicle is NOT acceptable. Substitution of control modules does not
guarantee confirmation of a fault, and may also cause additional faults in the vehicle being tested and/or the donor vehicle.
1. Verify the customer concern.
2. Visually inspect for obvious signs of damage and system integrity.

Visual Inspection
Mechanical Electrical
Parking brake cable
Parking brake actuator
Brake caliper
Brake pads
Stabilizer bar drop link caps

3. If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to
the next step.

4. If the cause is not visually evident check the system for any logged Diagnostic Trouble Codes (DTCs) and proceed to
the DTC Index , alternatively, verify the customer concern and refer to the Symptom Chart.

Electric parking brake release tool link lead 206-082-01. Only to be used for EMERGENCY brake
release
WARNING: Failure to release the tension and calibrate the electric parking brake during rear parking brake related service
procedures, could cause the parking brake to function incorrectly or become inoperative.


1. WARNING: Always use Jaguar approved diagnostic equipment to
release the cable tension, when carrying out repair operations on the
electric park brake which require cable tension release.

Connect the Jaguar approved diagnostic equipment to release the
electric parking brake cable tension.
Follow the on-screen instructions.


2. WARNING: The procedure below should only be used in emergency
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
