JLR BCM Module DX23-14D628-AH Virginized EEPROM

Product Overview

The JLR BCM Module DX23-14D628-AH Virginized EEPROM delivers a straightforward fix for typical body control failures in Jaguar Land Rover vehicles. When the original BCM stops communicating or malfunctions, your lights, locks, wipers, or even the starting system may act up. You can quickly restore everything with this direct-fit unit. Because we virginize the memory, you skip the complicated world of EEPROM dumps and binary editing. The module arrives completely blank, identical to the factory state before the first vehicle ever wrote data to it. This makes the JLR diagnostic programming routine seamless—just install, connect, and let the software do the work.

The Virginization Advantage

JLR stores immobilizer secrets and configuration maps in the BCM’s serial EEPROM. A pre-owned module holds the donor vehicle’s VIN and security tokens. Those old values clash with your car’s immobilizer and engine ECU, preventing a successful handshake. Manually editing the binary dump requires specialised programmers, careful checksum calculations, and often multiple trial-and-error attempts. Our virginization eliminates all that. We wipe the entire memory space and confirm every address reads as factory default. The diagnostic session then loads your vehicle’s exact As-Built data, ensuring perfect integration with the original immobilizer and convenience systems.

Technical Specifications

• Range Rover Velar (L560) 2017 – 2019
• Jaguar F-Pace (X761) 2016 – 2019
• Jaguar XE (X760) 2015 – 2019
• Jaguar XF (X260) 2015 – 2019

For an exact fitment check, send us your VIN and current part number. We answer quickly and confirm cross-compatibility where possible.

How to Program Your New BCM

1. Swap the defective BCM for our virginized DX23-14D628-AH (usually located behind the glovebox or in the boot, depending on model).
2. Connect your JLR-specific diagnostic interface (Mongoose Pro, VXDIAG, or equivalent).
3. Launch JLR SDD or Pathfinder software and perform a vehicle scan.
4. Navigate to the “Programmable Module Installation” or “Immobilization” function.
5. The software detects the blank module and automatically prompts for the VIN.
6. Allow the tool to download the original vehicle configuration and write it to the BCM.
7. Synchronise the keys and clear any stored fault codes.
8. Verify all body functions—lights, wipers, central locking, alarm, and starting.

The entire process takes around 25 to 40 minutes and requires no extra hardware beyond your standard diagnostics kit.

Frequently Asked Questions

Q: Do I need any special tools to install this BCM?
A: Only the diagnostic tool you normally use for JLR diagnostics and programming. You do not need an EEPROM reader or soldering iron.

Q: What if my original part number has a different suffix?
A: JLR often updates suffixes without changing hardware. We recommend matching exactly, but many suffixes interchange. Provide both part numbers for a quick compatibility check.

Q: Can you pre-programme the module with my VIN?
A: We supply the module in virgin state to give you full control. However, we offer a pre-programming service separately—please contact us for details and current turnaround times.
