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
campaigns. Refer to the
corresponding bulletins and SSMs which may be valid for the specific
customer complaint and complete the
recommendations as required
