Is your Volvo Automatic High Beam Sensor Failing? Troubleshooting Guide

All modern Volvos have plenty of features including automatic headlight switching based on traffic conditions. The feature is designed to help the driver easily switch between high and low beams based on road and traffic conditions. Although it is a convenient feature in older Volvos but once it starts malfunctioning then there may be a problem.

Functionality of Volvo Automatic High Beam

Volvo's Automatic High Beam technology comes equipped with a forward-facing sensor or camera located at the rear portion of the windshield above the rear window. The sensor detects road conditions ahead of the car and monitors the light from oncoming vehicles, the tail lights of vehicles ahead and various street lighting sources.

Check for the Windshield First

Watch out for the back mirror area. This should contain the camera module. Clean the windshield both inside and outside using automotive glass cleaner and microfiber windshield glass cleaner. While testing the system, there should not be any frost or condensation. If you observe these conditions then you need to wait for enough time for complete defrosting.

Moreover, keep a watch out for any damage to your windshield. Any flaw, even a little one on your windshield in the camera's area may reduce the functioning efficiency of the sensor. You might need to recalibrate your camera after the recent windshield replacement. It is a common occurrence following glass replacement especially when Volvo equipment has not been used for this purpose.

Check if the feature is turned on

The right way to turn on the vehicle is found in the owner's manual. It must be noted that the headlight switch has to be placed in the Auto mode in order for this feature to function in some cars. Automatic high beams do not turn on if the lights were manually switched on.

Weather or uneven road conditions

Even though the automatic headlight control system is smart but there are flaws. They cannot perform in weather conditions that affect visibility. These weather conditions include fog, rain, snow, or mist. Such weather conditions tend to split the light and thus the camera may not be able to recognize the headlight. Consequently, this would lead the automatic control system to either suspend for only a brief period or malfunction altogether.

There is the chance of the camera being distracted by the bright reflections coming from the road signs, wet surfaces, areas of construction or street lights. It might mistake these bright reflections for lights and therefore fail to operate appropriately due to having the low beams on.

Check the Headlights and Bulbs

Check if the two types of beams including both high and low ones work through manual controls. The high beam failure might be associated with the bulbs, LED modules, fuses, wiring, relays or headlight control units. In the case of electronic control of the headlights like those found in modern Volvos using LED lights, consulting an expert may become necessary to diagnose any failures.

The next factor that should be considered is that of alignment. Improperly aimed or positioned headlights will negatively impact the work of other systems operating at night. Suspension issues or minor collisions as well as replacement of headlights may cause improper alignment.

Batteries and Software Problems

An electronic warnings or slow ignition indicate that you should have your car's battery checked. The performance of camera modules, lighting systems and driver assistance systems will be affected when there is low voltage.

Software can be another factor here. Volvo frequently updates the vehicle's systems which leads to enhanced functionality or systems in the camera light, camera operations and faults in it. You can contact an authorized Volvo specialist at the dealership for an update on whether your vehicle requires any software updates.

When to Consult Professionals

After cleaning the headlights, testing the settings and performing a manual test if the problem persists and a professional diagnosis is needed. The professionals will run a scan on the car to know the trouble code, conduct a camera module test and a lighting test. They will also assess your car's battery condition and whether calibration is required.
