Range Rover Evoque: Headlamps

Principle of Operation

Three types of headlamp are available: Halogen, bi-xenon or Adaptive Front Lighting System (AFS).

For a detailed description of the headlamps operation, refer to the relevant Description and Operation section of the workshop manual. REFER to: (417-01 Exterior Lighting)

Given the potential for personal injury, the following safety information should be followed at all times:

Safety Information

WARNING: The xenon headlamp system generates up to 28,000 volts. Make sure that the headlamps are switched off before working on the system. Failure to follow this instruction may result in personal injury.

The following safety precautions must be followed when working on the xenon headlamp system:

1. DO NOT attempt any procedures on the xenon headlamps when the lights are switched on.

2. Handling of the xenon bulb must be performed using suitable protective equipment, e.g. gloves and goggles. The glass part of the bulb must not be touched.

3. Xenon bulbs must be disposed of as hazardous waste.

4. Only operate the lamp in a mounted condition in the reflector.

There are comprehensive instructions on the correct procedures for xenon headlamp system repairs in the 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 checked and/or the donor vehicle.

1. Verify the customer concern.

• Note that intermittent fault reports may be due to the cycling operation of the Field Effect Transistors (FETs)

2. Visually inspect for obvious mechanical or electrical faults.

Visual Inspection

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

4. If the cause is not visually evident check the system for any logged Diagnostic Trouble Codes (DTCs) and proceed to the DTC Index, alternatively, verify the customer concern and refer to the Symptom Chart.

Symptom Chart

DTC Index

For a complete list of all Diagnostic Trouble Codes (DTCs) that could be logged on this vehicle, please refer to Section 100-00.

REFER to: Diagnostic Trouble Code (DTC) Index - DTC: Central Junction Box (CJB) (100-00 General Information, Description and Operation).

Headlamp Leveling

Principle of Operation

Two systems of headlamp leveling are available: static and dynamic. Prior to diagnosis, identify the headlamp leveling system installed to the vehicle. Dynamic headlamp leveling is only available on vehicles with an Adaptive Front Lighting System (AFS).

For a detailed description of the headlight leveling system, refer to the relevant Description and Operation section of the workshop manual. REFER to: (417-01 Exterior Lighting)

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 checked and/or the donor vehicle.

1. Verify the customer concern.

2. Visually inspect for obvious signs of damage and system integrity.

Visual Inspection

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

4. If the cause is not visually evident check the system for any logged Diagnostic Trouble Codes (DTCs) and proceed to the DTC Index, alternatively, verify the customer concern and refer to the Symptom Chart.
