Auto High Beam Assist (AHBA) — JLR Retrofit Activation

Auto High Beam Assist (AHBA) transforms your night driving experience. The system automatically switches your headlights between high and low beam, so you enjoy maximum road illumination without constant manual input. This JLR retrofit activates the factory AHBA function on compatible Jaguar and Land Rover vehicles.

Technical Overview

AHBA relies on the vehicle’s forward-facing camera, known as the Image Processing Module A (IPMA). The camera monitors the road ahead for oncoming headlights, leading vehicle taillights, and ambient light levels. When conditions allow, the system engages the high beam. When the camera detects another vehicle or sufficient ambient light, the system dips to low beam. Once the road ahead clears, the system returns to high beam.

This function integrates directly with the Body Control Module (BCM), Gateway Module (GWM), and headlamp control circuitry. The vehicle’s existing light switch and instrument cluster settings support the feature. Drivers operate AHBA through the factory headlight switch in the Auto position. A dedicated menu option in the touchscreen or instrument cluster allows you to enable or disable the system at any time.

How Auto High Beam Assist Works

The system activates when driving above a calibrated speed threshold, typically around 40 km/h (25 mph). The IPMA camera then scans the road continuously. It distinguishes between oncoming traffic, leading vehicles, and street lighting. When the path ahead is clear and dark, the system raises the high beam. When it detects another vehicle, it lowers the beam to prevent glare.

The driver always maintains full control. You can override the system at any moment using the headlight stalk. The system then resumes automatic operation when conditions allow. This balance of automation and manual control delivers a confident and relaxed night driving experience.

Activation Process

Our JLR-certified activation begins with a vehicle compatibility check using your VIN. We verify whether your vehicle already carries the required IPMA camera and compatible light switch. When the hardware is present, we enable AHBA through factory CCF parameter coding. This software-only approach preserves your vehicle’s original JLR architecture.

If your vehicle lacks the necessary camera or switch, we supply and install genuine JLR components. This includes the IPMA camera, wiring harness, and auto-dim rear-view mirror where required. We then perform full configuration and calibration. Every installation concludes with a comprehensive diagnostic scan to confirm zero DTC faults and correct module communication.

Key Benefits

• Enhanced Night Safety: The system reacts faster than manual switching, reducing glare for other drivers.
• Effortless Convenience: You focus on the road while the vehicle manages high beam control.
• Full OEM Integration: AHBA works through factory modules, switches, and menus.
• No Aftermarket Parts: The retrofit uses genuine JLR hardware and software protocols.
• Driver Override: You retain complete control whenever you choose to intervene.

Frequently Asked Questions

Does my vehicle already have the required hardware?

Many JLR vehicles include the IPMA camera for other driver assistance features. We confirm this through your VIN before activation. If your vehicle lacks the camera, we supply and install the correct JLR components.

Will Auto High Beam Assist affect my warranty?

Our activation uses factory CCF parameter enablement and genuine JLR parts. This approach maintains your vehicle’s original software architecture and supports warranty compliance.

How long does the installation take?

Software-only activation typically completes within one hour. Hardware installation requires additional time depending on your vehicle model and existing configuration.

Can I turn the system off?

Yes. You can enable or disable AHBA through the vehicle settings menu. The headlight switch also allows manual override at any time.
