Land Rover Defender: Parking Brake
DIAGNOSIS AND TESTING
PRINCIPLES OF OPERATION
For a detailed description of the electric park brake, refer to the relevant
Description and Operation section in the
workshop manual.
INSPECTION AND VERIFICATION
CAUTIONS:
- 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.
- Please note this is a sealed unit and no attempt must be made to open
the actuator as it will invalidate any
warranty claim.
NOTES:
- If a control module or a component is at fault and the vehicle
remains under manufacturer warranty, refer
to the Warranty Policy and Procedures manual, or determine if any prior
approval program is in operation,
prior to the installation of a new module/component.
- Generic scan tools may not read the codes listed, or may read only
5-digit codes. Match the 5 digits from
the scan tool to the first 5 digits of the 7-digit code listed to identify
the fault (the last 2 digits give extra
information read by the Jaguar Land Rover approved diagnostic equipment).
- When performing voltage or resistance tests, always use a digital
multimeter that has the resolution ability
to view 3 decimal places. For example, on the 2 volts range can measure 1mV
or 2 K Ohm range can
measure 1 Ohm. When testing resistance always take the resistance of the
digital multimeter leads into
account.
- Check and rectify basic faults before beginning diagnostic routines
involving pinpoint tests.
- Verify the customer concern
- Visually inspect for obvious signs of damage and system integrity
Visual Inspection
- If an obvious cause for an observed or reported concern is found,
correct the cause (if possible) before
proceeding to the next step
- If the cause is not visually evident, verify the symptom and refer to
the Symptom Chart, alternatively check for
Diagnostic Trouble Codes (DTCs) and refer to the DTC Index
- Check the JLR claims submission system for open campaigns. Refer to the
corresponding bulletins and SSMs
which may be valid for the specific customer complaint and complete the
recommendations as required
