JLR BCM Module DX23-14B476-AG Virginized EEPROM
Product Overview
When your Jaguar Land Rover begins showing inexplicable electrical glitches—headlights staying on, wipers triggering without command, or an immobiliser that refuses to recognise the key—the body control module (BCM) often sits at the root of the problem. The JLR BCM Module DX23-14B476-AG Virginized EEPROM removes the hassle of swapping a used unit. We erase the EEPROM down to every last bit and verify the blank state before it leaves our bench. This transforms a previously programmed module into a factory-fresh blank device that your JLR-approved diagnostics can programme from scratch.
The Power of a Virginized BCM
Standard used modules carry the VIN, key codes, and configuration from another vehicle. When you connect the module to your car, the software detects the mismatched data and either locks up or corrupts the immobiliser routine. Many technicians then waste hours editing hex dumps, calculating checksums, and hoping for a clean write. A virginized BCM short-circuits all that complexity. By resetting the memory to a known blank state, we give you the same starting point the factory intended. Your diagnostic tool recognises the blank module, pulls the correct As-Built data from the JLR server, and writes a clean, verified configuration without a single checksum error.
Technical Specifications
- Part Number: DX23-14B476-AG (compatible suffixes include AF, AH on many models—always check your label)
- Memory: Serial EEPROM, full sector erase and byte-level verification to guaranteed blank condition
- Communication Protocols: High-speed CAN, low-speed CAN, and LIN bus for peripheral control
- Pre-Shipment Testing: Each module undergoes a full bench simulation checks power supply rails, CAN signal quality, and correct activation of all output channels (lighting, wipers, locks, horn, alarm)
- Packaging: Sealed anti-static bag with protective foam insert and security seal
Vehicle Compatibility
This BCM fits a wide range of JLR vehicles, predominantly from 2014 to 2019. We always recommend matching the part number on your original unit exactly. Typical applications include:
- Range Rover (L405) 2013 – 2017
- Range Rover Sport (L494) 2014 – 2017
- Discovery 5 (L462) 2017 – 2019
- Range Rover Velar (L560) 2017 – 2019
- Jaguar F-Pace (X761) 2016 – 2019
- Jaguar XE (X760) 2015 – 2019
- Jaguar XF (X260) 2015 – 2019
If your vehicle falls outside these ranges or carries a slightly different suffix, reach out with your VIN. We confirm cross-compatibility quickly and accurately.
Step-by-Step Installation and Programming
- Remove the defective BCM and plug in the virginized DX23-14B476-AG replacement.
- Connect your JLR diagnostic tool (Mongoose Pro, VXDIAG, or a genuine dealer VCI).
- Launch the appropriate software—JLR SDD for 2014–2016 models, Pathfinder for 2017 and newer.
- Perform a network health check to ensure all ECUs are visible.
- Select “Programmable Module Installation” (PMI) or “Replace Module” from the menu.
- When the system detects the blank BCM, follow the prompts to enter your VIN.
- Allow the tool to download the vehicle’s full configuration package and write it to the module.
- Complete the immobiliser synchronisation procedure, clear any fault codes, and test all body functions.
Most technicians finish the entire job in under 30 minutes. No soldering, no external EEPROM reader—just your standard diagnostic setup.

Why SX-CAN.com is Your Trusted Supplier
Our workshop specialises exclusively in Jaguar Land Rover electronics. We do not dabble in generic modules; we know the exact protocols and memory layouts JLR employs. Each DX23-14B476-AG passes through a rigorous bench-test procedure that mimics the electrical environment of a running vehicle. We check power-up behaviour, CAN message timing, and full load testing on every output pin. Only after a perfect pass do we pack and ship the module. This discipline means that when you receive your virginized BCM, it works the first time you plug it in.
Frequently Asked Questions
Q: Can I use this BCM if my original part number is DX23-14B476-AF?
A: Usually, yes. The hardware remains identical across many suffix changes. However, we strongly encourage an exact match where possible. Send us both part numbers for a definitive answer.
Q: Does this module need any special tools for programming?
A: None beyond your current JLR diagnostic interface. We have already virginized the EEPROM, so you simply follow the onboard programming routine.
Q: What if I encounter a programming failure?
A: Because we test every module before shipping, genuine hardware failures are extremely rare. If you do face a difficulty, our technical team will guide you through the correct process. If the module proves faulty, we ship a replacement immediately under our 12-month warranty.
