Auto High Beam Assist (AHBA) Retrofit — JLR OEM Activation
Auto High Beam Assist (AHBA) delivers factory-grade automatic high-beam control for your Jaguar or Land Rover. This retrofit activation unlocks the genuine JLR software logic already built into your vehicle’s forward-facing camera and headlamp control modules. You gain improved night-time visibility, reduced driver workload, and full compliance with OEM ADAS calibration standards — without adding aftermarket hardware.
Overview: Genuine JLR AHBA Functionality
The JLR Auto High Beam Assist system operates through the vehicle’s Image Processing Module A (IPMA) and forward-facing camera. The camera continuously scans ambient light levels, oncoming traffic headlights, and roadside lighting conditions. When the system detects darkness and an absence of other vehicle lights, it automatically engages the high beam. The moment the camera identifies oncoming headlights or preceding tail lights, the system smoothly dips to low beam and restores high beam once the road clears.
Factory OEM logic governs this behaviour through calibrated speed thresholds. High beams activate above 40 km/h on unlit roads and automatically dip below 24 km/h for urban environments. Many JLR vehicles leave the factory with the necessary camera and LED headlamp hardware installed, yet the AHBA software flag remains dormant due to trim-level configuration locks. This retrofit activation writes the genuine JLR AHBA configuration into your vehicle’s Central Car Configuration (CCF) and synchronises the camera module, Body Control Module (BCM), and headlamp control units.
You receive a dealer-compliant, fully reversible programming service that preserves every existing factory lighting function — daytime running lights, follow-me-home lighting, and adaptive cornering illumination all remain operational.

Why Activate Auto High Beam Assist?
You drive with maximum illumination. The system maintains high beam whenever road conditions allow, then dips automatically for oncoming vehicles. You no longer toggle the stalk manually on dark stretches of road.
You reduce night-time driver fatigue. Long journeys in low-light conditions demand constant attention. AHBA handles the repetitive high-beam switching task, so you focus on the road ahead.
You improve road safety for everyone. The camera detects oncoming headlights and preceding tail lights faster than human reaction allows. Glare reduction for other drivers happens instantly and smoothly.
You preserve your vehicle’s factory integrity. This activation writes only dormant OEM parameters. It never overwrites core ADAS firmware or introduces third-party code. Your vehicle retains full diagnostic integrity and warranty compliance.
Vehicle Compatibility
This AHBA activation service suits most modern Jaguar and Land Rover platforms equipped with the forward-facing camera and LED or xenon headlamp assemblies. Supported models include:
- Range Rover (L460) — 2022 onwards
- Range Rover Sport (L461) — 2023 onwards
- Defender (L663) — 2020 onwards
- Range Rover Velar, Evoque — late-model variants
- Jaguar F-Type (X152), XJ (X351), XF — models with factory LED headlights and forward camera
Your vehicle requires the forward-facing camera integrated into the rear-view mirror housing or windscreen-mounted IPMA. Where the camera exists, the hardware fully supports AHBA. Where the camera is absent, we supply and install the genuine camera module as a separate retrofit package. A VIN decode confirms compatibility before purchase.
What the Activation Service Includes
- Pre-calibration diagnostics: We read all ADAS and BCM fault codes, confirm camera presence, and audit the current CCF configuration.
- OEM configuration programming: We write the genuine JLR AHBA activation flag and, where required, flash the latest AHBA control map.
- Camera alignment: We perform forward-camera calibration to JLR specification, ensuring accurate traffic detection and beam transition timing.
- Post-upgrade validation: We run a full functional test, verify zero dashboard warnings, and confirm smooth beam switching on road.
We complete the activation remotely via secure OBD connection or at our workshop. You receive documentation confirming the configuration change and your vehicle’s restored factory settings path.
Order Auto High Beam Assist Activation
Add the AHBA activation to your cart, complete checkout, and our technical team contacts you within one business day to schedule your session. You provide your VIN, and we confirm compatibility before we begin. The entire process takes under two hours, and you drive away with genuine JLR Auto High Beam Assist operational from the moment you select the function.
Bulk and workshop pricing available. Contact us for tiered rates on 5 or more activations.
