Land Rover Discovery: Parking Aid Proximity Camera / Diagnosis and Testing
PRINCIPLES OF OPERATION
For a detailed description of the rear view camera system, refer to the
relevant Description and Operation section of 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:
- If a control module or a component is suspect and the vehicle
remains under manufacturer warranty, refer to the Warranty Policy
and Procedures manual, or determine if any prior approval
programme is in operation, prior to the installation of a new
module/component.
- When performing voltage or resistance tests, always use a digital
multimeter accurate to three decimal places, and with an up-todate
calibration certificate. 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 DDW for open campaigns. Refer to the corresponding bulletins
and SSMs which may be valid for the specific customer complaint and
carry out the recommendations as required

NOTE:
A blank screen is the default display when the rear view camera is not
transmitting an image.
CAUTION:
Do not probe the coaxial cable connectors as they are prone to
damage.
NOTE:
A DC resistance measurement is not a reliable test method as the
system operates at low voltage and high frequency.
NOTE:
A blue screen is the default display when the video in signal is absent.
NOTE:
The vehicle may take 30 seconds (or 100m) to learn the steering
centre position after starting the engine. This is normal.
