Scan Tool Operating Instructions - AK Automotive Training

FastCheck
Any other EPB system component has been replaced:
1. DTCs should be read and cleared.
2. The 'Assembly Check' function should be performed to check the operation of the
parking brake system.
3. If the 'Assembly Check' function fails, DTCs should be read again and the
problem investigated.
The Parking Brake will not engage when manually operated via the button:
1. Ensure that the system is NOT in 'Maintenance Mode'. If it is, then perform the
'Exit Maintenance Mode' function.
2. Read DTCs, there may be a DTC stored which will indicate the area of the fault.
3. Clear DTCs, there may be an intermittent fault on the system which needs to be
cleared.
4. Perform the 'Static Apply' function. This will send a command directly to the
Control Module which will then close the actuators to the nominal 'engaged'
position.
5. Check the switch/button.
6. Check the actuators themselves or the wiring from the ‘Control Module’ to the
actuators.
Land Rover - Electronic Parking Brake (EPB) System
Discovery III (L319) (2005 - 2009), Range Rover Sport (L320) (2005 -
2009), Range Rover (L322) (2006 - 2009):
There are four functions available under the PBM/EPB ‘Service Brakes’ menu:
Unjam Electronic Parking Brake
This procedure should be used if one of the Parking Brake cables becomes detached
or breaks whilst the vehicle is being driven.
Pre-Test conditions:
• The vehicle must be stationary
• The engine must be running and at idle speed
After performing the procedure it is necessary for the technician to carry out checks
on the condition of the rear brake shoes and drums. If both are OK the technician
should then refer to the Land Rover technical information.
NOTE: Part of this procedure is to place the Parking brake into ‘Mounting Position’; in
order for the checks of the rear brake shoes and drums to be carried out. When the
vehicle is in the 'Mounting Position' a red flashing light will appear on the instrument
cluster. This indicates that the parking brake actuator is in the 'Mounting Position'. It
does not indicate a vehicle fault.
