What This Virgin EEPROM Data Delivers

The Liftgate Control Module (also called the Tailgate Control Module or TGCM) manages every powered tailgate function on your Jaguar Land Rover vehicle. It controls opening, closing, height memory, obstacle detection, and soft-close operation. The module stores vehicle-specific configuration data in its EEPROM memory, including the VIN, calibration values, and the security pairing data that links it to the original vehicle.

When you fit a used liftgate module from a donor vehicle, the module remains paired to its original car. Your vehicle will not accept it. The tailgate may fail to operate, throw fault codes, or refuse to respond entirely. The same problem occurs when the original module corrupts its EEPROM data through a voltage spike, water ingress, or an interrupted programming attempt.

Our HK52-14B673-AD Virgin EEPROM Data File solves this problem. The file contains validated blank data that resets the module to its factory-unmarried state. You write this data to the module’s EEPROM using a compatible programmer, then configure the module to your vehicle using JLR Pathfinder. The tailgate then operates as a fully integrated factory component.

The HK52-14B673-AD variant appears in the latest generation of Jaguar Land Rover vehicles with powered tailgate systems. It suits Range Rover L460, Range Rover Sport L461, Defender L663, Discovery 5, Velar L560, and Jaguar F-Pace, XE, XF, E-Pace, and I-Pace models from approximately 2020 onwards. You must confirm your module part number matches before ordering, because JLR used several hardware revisions across model years.

Technical Specifications

How the Virgin EEPROM Process Works

1. Module Removal & Identification: Remove the liftgate control module from the vehicle and confirm the part number reads HK52-14B673-AD.
2. EEPROM Read & Backup: Connect your programmer to the module’s EEPROM chip and read the existing data. Save this original file in case you need to restore it later.
3. Virgin Data Write: Write our validated virgin EEPROM file to the module using your programmer. The module returns to a blank, unmarried state.
4. Module Reinstallation: Refit the module to the vehicle and connect your JLR diagnostic equipment (Pathfinder for this 2020+ platform).
5. Configuration & Calibration: Use Pathfinder to configure the module to your VIN, set the correct calibration values, and complete the anti-theft synchronisation handshake.
6. Functional Verification: Test the tailgate operation through multiple open and close cycles, confirm height memory settings, and check for any stored fault codes.

Why Choose This Virgin EEPROM Data

• Validated & Ready to Write: Every file passes checksum verification and structural validation before we deliver it. You write it once and proceed with configuration.
• Saves a Dealer Replacement: A new liftgate module from a JLR dealer often costs hundreds of pounds. Our data file renews a used module at a fraction of that cost.
• Restores Full Functionality: Once configured, the module controls every powered tailgate function exactly as the factory intended, including height memory and obstacle detection.
• Instant Delivery: You receive the download link by email immediately after order confirmation, so you can start the repair the same day.
• Latest Generation Coverage: The HK52-14B673-AD variant suits the newest JLR models from 2020 onwards that require Pathfinder for configuration.
• Technical Support Included: Our JLR specialists answer your questions about the write process and the subsequent Pathfinder configuration steps.

Important Technical Considerations

Always back up the original EEPROM data before writing any new file. If the module’s existing data remains intact, you can restore it later if needed. Once you write virgin data, the module loses its previous configuration permanently unless you hold a backup.

Confirm the module part number before ordering. JLR used several hardware revisions across model years, and the wrong data file may fail to write correctly or produce a non-functional module. If you are unsure, contact us with your VIN and we will confirm the correct file for your vehicle.

The final configuration step requires a stable power supply maintaining 13.5 V or higher throughout the session. A voltage drop during module configuration can corrupt the newly written data and leave the module inoperable. Connect a JLR-approved battery support unit before you begin.

Frequently Asked Questions

Is this a physical module or just a data file?

This listing is for the virgin EEPROM data file only. We deliver it as an instant digital download. You must already have a compatible HK52-14B673-AD liftgate control module.

What tools do I need to use this file?

You need an EEPROM programmer compatible with the module’s memory chip, a soldering or chip-reading setup if your programmer requires direct connection, and access to JLR Pathfinder diagnostic software for the final configuration.

Can I use this file on any liftgate module?

No. This file suits the HK52-14B673-AD module variant only. Confirm your module part number before ordering. Contact us with your VIN if you need us to confirm the correct file.

Will the tailgate work immediately after writing the file?

No. After writing the virgin data, you must configure the module to your vehicle using JLR Pathfinder. The module needs its VIN, calibration values, and security pairing set before the tailgate operates.

Can I reverse the process if something goes wrong?

Yes, if you back up the original EEPROM data before writing. We always recommend saving the original file. If you hold that backup, you can restore the module to its previous state.

Do you offer support during the process?

Yes. Our JLR specialists answer technical questions about the write process, the Pathfinder configuration steps, and any fault codes that appear after installation. Contact us at any point and we will help you resolve the issue.
