Range Rover Auto High Beam Assist (AHBA) Troubleshooting
Experiencing issues with your Range Rover’s Auto High Beam Assist (AHBA)? Many Range Rover owners appreciate the convenience of AHBA, which automatically switches between high and low beams for optimal visibility and safety during nighttime driving. However, sometimes this system can malfunction, leading to frustration. If your Range Rover AHBA is not working as expected, you’re in the right place to explore potential causes and solutions.
One common scenario involves a “Sensor Blocked” warning message appearing on your dashboard. This alert typically indicates that the AHBA sensor, usually located near the rearview mirror, is obstructed. Even if the warning disappears, the AHBA system might remain inactive. The sensor, often mistaken for the rain/light sensor, is a small camera lens responsible for detecting oncoming traffic and adjusting your headlights accordingly.
A frequent culprit for a blocked sensor is surprisingly simple: obstructions on the windshield. Check for anything that might be in the camera’s line of sight. This could include something as innocuous as a new state inspection sticker placed too close to the sensor. Grime, dirt, or even dangling objects like parking passes can also impede the sensor’s functionality. A gentle cleaning of the windshield area around the sensor lens with a soft wipe is a good first step to rule out dirt or debris.
If cleaning the sensor area doesn’t resolve the issue, verify that AHBA is still enabled in your vehicle settings. Navigate to your instrument cluster menu by using the OK button on your steering wheel and look for “Vehicle Setup” or similar. Then, find “High Beam Assist” and ensure that the “Activate” option is checked. Sometimes, a temporary blockage or system glitch can deactivate the feature, requiring manual reactivation.
In some cases, despite no warning messages or visible obstructions, the AHBA sensor itself might be faulty. While bad weather conditions are unlikely to permanently damage the sensor, electronic components can sometimes fail. If you’ve tried the troubleshooting steps above and your Range Rover Auto High Beam Assist remains unresponsive, a professional diagnosis might be necessary. Consulting a certified Range Rover technician will help determine if the sensor or another part of the AHBA system needs repair or replacement.
