Land Rover Defender: Near Field Sensing Module

DIAGNOSIS AND TESTING

PRINCIPLES OF OPERATION

For a detailed description of the parking aid system, refer to the relevant Description and Operation section of the workshop manual.

INSPECTION AND VERIFICATION

CAUTIONS:

• If the 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.
• 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
• Do not apply any grease based products to any parking aid system connector or pins

NOTE: Check 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.

1. Verify the customer concern
2. Visually inspect for obvious signs of mechanical or electrical damage
3. Make sure that the parking aid sensor face is clear of contamination that could affect the performance of the sensor
4. If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step
5. If the cause is not visually evident, verify the symptom and refer to the Symptom Chart.

Visual Inspection

CAMERA SYSTEM SYMPTOM CHART

CAMERA SYSTEM PINPOINT TESTS

PINPOINT TEST A : PERMANENT BLANK SCREEN TESTS

PINPOINT TEST B : CAMERA SYSTEM UNAVAILABLE

PARKING AID SYSTEM ON-BOARD SELF-TEST

As part of the strategy of the system if any Diagnostic Trouble Code(s) are detected a parking aid warning message will be displayed on the touchscreen

• If a fault is present when the parking aid system is activated then the parking aid button on the touchscreen will be unavailable for selection indicating an issue with front or rear parking aid sensors, wiring, near field sensing module or the in car infotainment system

Visual Warnings when Parking Aid System is in Error State

PARKING AID SYSTEM INSTALLED

A parking aid warning message will be displayed on the touchscreen and the parking aid button on the touchscreen will be unavailable for selection. Every time the parking aid system is activated within the same ignition cycle a parking aid warning message will be displayed on the touchscreen

NOTES:

• Make sure the in car infotainment system is fully functional and configured correctly
• Parking aid sensors that are painted incorrectly and not to the manufacturer standards, will not be considered in any warranty claim

WARRANTY COMPLIANCE AND PROCEDURES IN RELATION TO CAMERAS SUFFERING FROM STONE CHIPPING

Where there is clear evidence that a camera lens has sustained damage due to stone chipping, abrasions or other impact damage that has resulted in poor or blurred/foggy image and similar symptoms, retailers should note that this form of damage is regarded as wear and tear and, therefore rectification of this damage is NOT claimable under any of the vehicle warranties. Retailers are referred to Section B1.45 (Guide To Warranty Terms And Conditions - General Items - Stone Chips/Paint Damage) in the Global Warranty Compliance And Procedures Manual, which can be found in the Warranty Manual section of the Retailer Standards and Training Documents on TOPIx. Further information can also be found in Section A1.7 (Warranty Terms And Conditions - Summary of Vehicle Warranty - What is Not Covered By The Vehicle Warranty).

GUIDANCE FOR CORRECT IDENTIFICATION OF STONE CHIP DAMAGE

The image below shows clearly that an impact from a stone chipping or another object has pitted the surface of the camera lens. The pits/indentations should also be detectable by feeling the surface of the lens and checking the surface profile for indentations. This kind of damage would NOT be covered by vehicle warranty.

The images below show the front and rear view camera images you would expect to see from a damaged camera lens. This kind of damage would NOT be covered by vehicle warranty.

WARRANTY COMPLIANCE AND PROCEDURES IN RELATION TO PARKING AID SENSORS SUFFERING FROM CORROSION DUE TO STONE CHIPPING

Where there is clear evidence that a parking aid sensor has sustained damage due to stone chipping or other impact damage that has resulted in corrosion and subsequent malfunction, retailers should note that this form of damage is regarded as wear and tear and, therefore rectification of this damage is NOT claimable under any of the vehicle warranties. Retailers are referred to Section B1.45 (Guide To Warranty Terms And Conditions - General Items - Stone Chips/Paint Damage) in the Global Warranty Compliance And Procedures Manual, which can be found in the Warranty Manual section of the Retailer Standards and Training Documents on TOPIx. Further information can also be found in Section A1.7 (Warranty Terms And Conditions - Summary of Vehicle Warranty - What is Not Covered By The Vehicle Warranty).

GUIDANCE FOR CORRECT IDENTIFICATION OF STONE CHIP DAMAGE AND RESULTING CORROSION

The image below shows clearly that an impact from a stone chipping or another object has pitted the surface of the parking aid sensor. The pits/indentations should also be detectable by feeling the surface of the sensor and checking the surface profile for indentations. This kind of damage would NOT be covered by vehicle warranty.

If left untreated, the damage to the face of the sensors caused by stone chips can cause corrosion to the painted surface of the parking aid sensor. The image below shows four examples of this form of corrosion. Note how, if the surface of the sensor appears to look like a crater, then this indicates that the corrosion has occurred as a result of earlier damage from stone chipping. This kind of damage would NOT be covered by vehicle warranty.
