How to Find the Right BECM Part Number for Your Range Rover

The Most Important Step: Finding the Correct BECM Part Number

When replacing a component as critical as the Battery Energy Control Module (BECM), there is zero room for error. Installing the wrong part will not work. This guide explains how to ensure you source the exact BECM for your Range Rover PHEV.

Why Is the Part Number So Critical?

Land Rover uses different BECM hardware and software versions across its model years and vehicle lines. A BECM for a 2019 Range Rover Sport P400e may be different from one for a 2022 Range Rover P440e. The differences can include:

• Internal hardware and processing power.
• Software designed for specific battery chemistries or capacities.
• Different communication protocols.

Installing the wrong part number will result in a programming failure. The vehicle's software will not recognize the module.

The Only 100% Reliable Method: Use Your VIN

Your 17-digit Vehicle Identification Number (VIN) is the key to your car's identity.

1. Locate your VIN (on the windshield or door jamb).
2. Contact a JLR parts specialist, such as the expert team at SX-Tool.
3. Provide them with your full VIN.

Using the official JLR Electronic Parts Catalogue (EPC), a specialist can look up your vehicle's specific build sheet. The EPC will identify the exact, most current part number required for your vehicle. This process also accounts for ‘supersessions,' where JLR has improved a part and replaced an old number with a new one. A specialist will always provide the latest correct version.

Can I Get the Number Off the Old Part?

Yes, but with a caution. The part number (e.g., `LK72-14B523-AG`) is printed on the old BECM. However, this part may have been superseded by a newer, improved version. Using your VIN is always the best practice to ensure you get the latest and greatest part from JLR.
