Land Rover Defender: Integrated Power Brake System
DIAGNOSIS AND TESTING
PRINCIPLES OF OPERATION
For a detailed description of the Integrated Power Brake System, refer to the
relevant Description and Operation
section in the workshop manual.
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.
NOTES:
- 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 mechanical or electrical damage
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
- Check the Jaguar Land Rover (JLR) claims submission system for open
