Easy Troubleshoots for Land Rover Automatic High Beam Sensor Faults

Each model of Land Rover is created for easy, safe and comfortable driving. Many Land Rover owners appreciate the automatic high beam technology. For switching the high beam lights to low and vice versa according to the illumination level and the presence of vehicles nearby.

If the technology works properly then you will enjoy improved visibility without the need to change the headlight stalk manually. The automatic high beams might fail to switch off at the appropriate time or fail.

How Does the Automatic High Beam Functioning Take Place in Land Rover?

A camera or a sensor installed in front, behind the windshield, near the rear-view mirror is the mechanism of operation in the Automatic High Beam system. If there is no obstruction in front and the road is dark then the lights will be activated. If there is any other car then the lights are changed back to low beam mode.

Problem-solving for the Land Rover Auto High Beam

Wipe the Windscreen Around the Camera Location

Clean the windshield especially in the area surrounding the camera located behind the mirror. The headlight auto system needs to see the road clearly but the sensor can be obstructed by any dirt, dust or even water droplets, insects, frost, salt on the roads or smudges on the sensor.

Use a strong yet soft microfiber cloth along with good-quality glass cleaner and clean the windscreen from the inside and outside. Furthermore, the reflective qualities of the camera may be affected due to the presence of grease in the film within the glass.

Weather and road conditions

The functioning of the automatic headlights on the Land Rover requires adequate visibility. There might be times when the lights are automatically deactivated because of certain weather conditions that impair visibility. There might be situations when the system becomes inactive as a result of heavy rainfall, fog, snowstorm, dusty environment or darkness.

This doesn’t always imply a fault in the system. Rather, this can be a precautionary measure undertaken by the software as a means of preventing the use of the vehicle in potentially dangerous situations. If this is not the case once the weather gets better than the problem might be inherent in the system itself.

Automatic high beam setup

One reason the headlights will not work properly is incorrect settings. This auto high beam feature is designed to activate under two specific conditions. Firstly, when the system’s headlights control function is set to the auto setting. Secondly, if the feature has been disabled in the vehicle settings.

Restart the Engine

There could be many control modules in use in a modern Land Rover and a software malfunction for just a brief period may occur. In case you have your AHB warning light flashing then you need to drive your vehicle at a moderate pace, turn it off, lock it, wait a few minutes and then restart the engine.

Check the State of the Battery

The battery of the vehicle plays an important role in your problem. It is because a low battery voltage may trigger a lot of different warnings including yours due to many electronic components used by the vehicle.

Windshield Replacement or Tinting Problems

If your car windscreen was recently installed in your Land Rover then calibration will be necessary. There must be exact camera adjustment and alignment that should be performed from the camera located at the front part of the car. The slightest change in the camera's positioning will cause a great difference in the interpretation of the road.

Problems with automatic high beam lights may occur due to poor glass quality or an inappropriate high beam installation that is poorly calibrated. After the replacement of your windshield, it is advised to proceed with its calibration.

Look for Condensation or Moisture near the Sensor

Any intrusion of water inside the windscreen camera housing will adversely impact the sensor readings. The sensor might not detect any clear signals if there is condensation around the backside of the or inside the mirror section or camera housing.

Verify Headlight Functionality

While the sensor itself may be working fine but the trouble could lie in the headlights. If one headlight flickers, shines improperly or does not work as expected then it could lead to poor performance of the automatic high beam system.
