MANUAL FUNCTIONS
The following can be performed manually without the scan tool:
Disable Parking Brake for Rear Brake Disc Change
This procedure is necessary before carrying out work on the rear brake discs. When
performed correctly the brake callipers are wound back by the control module:
Manual Routine:
• Turn the ignition key to position II.
• Apply, and hold, the footbrake,
• Apply, and hold, the parking brake switch to the RELEASE position.
• Turn the ignition key to position 0 and remove the key.
• Release the footbrake.
• Release the parking brake switch.
• Remove fuse number 8 from the BJB (to isolate the parking brake electrical circuit).
This will ensure safe working conditions and eradicate the threat of the parking brake
accidentally coming on while the technician is working on it.
To Re-enable Normal Operation:
• Re-install fuse number 8 into the BJB (to re-enable the parking brake electrical
circuit).
Parking Brake Shoes Bedding-in Procedure
This procedure must be carried out if, new parking brake shoes are fitted, new rear
brake discs are fitted or if the vehicle has been mud wading (not water) for more than
50 miles:
Manual Routine:
• Start and run the engine.
• Apply the footbrake 3 times within 10 seconds and hold applied after the 3rd
application.
• Apply the electronic parking brake switch 4 times, followed by 3 release
applications within 10 seconds.
Once the Service Bedding-in procedure mode has been entered, the electronic
parking brake linings can be bedded-in by conducting 10 repeated stops from 30
- 35 km/h (19 - 22 mph), followed by a 500 metre (547 yard) interval between each
stop to allow the brakes to cool, using the electronic parking brake control switch.
• The electronic parking brake force will be increased up to the dynamic maximum
so long as the switch is held in the applied position.
• If the switch is released to either the NEUTRAL or OFF positions, the electronic
parking brake will be released,
• The electronic parking brake MUST be allowed to cool between applications, either
by driving at 19 mph (30 km/h) for 500 metres (547 yards) or remaining stationary
for 1 minute between each application.
