Land Rover Discovery: Parking Aid Proximity Camera / Diagnosis and Testing

Land Rover Discovery (2009–2016) Service Manual / Electrical / Instrument and Warning Systems / 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.
  1. Verify the customer concern
  2. Visually inspect for obvious signs of damage and system integrity

Visual Inspection

Visual Inspection

  1. If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step
  2. 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
  3. 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

PINPOINT TESTS

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.

PINPOINT TESTS

PINPOINT TESTS

NOTE:

A blue screen is the default display when the video in signal is absent.

PINPOINT TESTS

NOTE:

The vehicle may take 30 seconds (or 100m) to learn the steering centre position after starting the engine. This is normal.

PINPOINT TESTS
