Range Rover L405 activates Auto High Beam Assist

OEM JLR HCM ADAS Lighting Coding | Factory Auto High Beam Assist Activation for Range Rover L405

Product Technical Overview

The Range Rover L405 platform features factory-installed forward-facing camera sensors and a dedicated Headlight Control Module (HCM). These core hardware components fully support automatic high-beam detection and switching functionality. However, JLR restricts this advanced ADAS feature on many base and mid-spec L405 models. It uses factory CCF configuration locking to disable Auto High Beam Assist from stock operation. As a result, owners must manually toggle high beams, despite having fully capable sensor and lighting hardware.

Stock Factory Lighting Limitations

Stock L405 factory lighting operates in manual-only high-beam mode. First, constant manual beam adjustment creates driver distraction during night travel. Second, incorrect high-beam usage causes glare for opposing traffic, which reduces road safety. In addition, generic aftermarket lighting mods create system conflicts. They often corrupt HCM calibration and trigger persistent ADAS DTC fault codes.

Core Technical Upgrade Benefits

Genuine OEM Automatic High Beam Control: After activation, the factory camera and HCM work in tandem. Therefore, high beams activate automatically in dark conditions and deactivate during oncoming traffic detection.
Improved Night Driving Safety: The intelligent system eliminates human error during low-light driving. Thus, visibility maximises while glare risk for other road users minimises.
Reduced Driver Workload: Drivers no longer need constant beam adjustment. Consequently, night journeys become safer and less fatiguing over long distances.
Full ADAS System Harmony: This feature integrates seamlessly with existing L405 lighting systems. Moreover, all factory sensor calibration and safety logic remains fully unchanged.
Zero Diagnostic Fault Codes: All parameter edits follow official JLR engineering standards. As a result, module logs remain clean with full dealer firmware update compatibility.
Permanent Feature Stability: Auto High Beam Assist functionality persists through battery resets, system scans and official JLR software updates.

Vehicle Compatibility

This HCM ADAS coding upgrade supports all Range Rover L405 model years fitted with factory front camera and LED headlight systems. It covers all petrol, diesel and hybrid powertrain trim levels.

Advantages Over Aftermarket Lighting Mods

Third-party lighting controllers use universal non-factory logic. Accordingly, they cause delayed detection, incorrect beam switching and ADAS faults. On the other hand, our OEM coding unlocks native factory programming. As a result, the system delivers precise, reliable and manufacturer-approved performance.
