Jaguar Land Rover vehicles are some of the most sophisticated vehicles on the road — not just in design and off-road capabilities, but in how deeply software integrates into their operations. From diagnostics and programming to retrofits and ECUs, every module in a modern JLR vehicle has to be managed through VIN-linked software platforms.
At LR Retrofit, we provide both access to official Jaguar Land Rover software tools and support for full-feature use, including:
- Module flashing and programming
- Comprehensive health diagnostics
- Feature unlocking via CCF/VCF edits
- Retrofit activations
- Security access and calibration
- Live remote diagnostics for local or international clients

What Are JLR Software Tools?
JLR software tools are proprietary platforms used by dealerships and specialists to perform coding, diagnostics, repairs, and updates on Jaguar, Land Rover, and Range Rover vehicles.
The most common official tools are:
- SDD (Symptom Driven Diagnostics) – for vehicles built before 2017
- Pathfinder – for vehicles from 2017 onward
- TOPIx Cloud – for online VIN decoding and ECU updates
- DOIP VCI – JLR’s current diagnostic interface
- Legacy Tools – IDS, JLR Mangoose, Rotunda VCM
These connect vehicles to a Windows laptop or tablet, allowing authorized users to read fault codes, test live data, code modules, replace ECUs, and perform retrofits with feature additions.

JLR SDD – Symptom Driven Diagnostics (2005–2016)
-
JLR Pathfinder (2017–Present)
- TOPIx Cloud – Technical Reference Library
- SX-TOOL JLR Engineering Tool for DoIP vehicles

What Interfaces Work with JLR Software?
| Interface | Works With | Notes |
|---|---|---|
| JLR DOIP VCI | Pathfinder / TOPIx | Official dealer interface, DOIP required |
| Mongoose Pro JLR | SDD (only) | Approved for older vehicles |
| DrewTech Cardaq+ | OEM J2534 | Works with SDD on select ECUs |
| JLR Enet | SDD / Pathfinder | JET-Pro / SXTool Used by independent specialists |
What Vehicles Need JLR Software Tools?
Every Jaguar Land Rover vehicle — from 2005 to present — uses main ECUs and system protocols that require dealer-level diagnostic tools.
| Tools | Compatible Models |
|---|---|
| SDD | Freelander 2, Evoque (<2016), L322/L320, XJ X351, XF X260 (pre-17), F-Type |
| Pathfinder | Discovery 5, Defender L663, Evoque L551, Velar, RR L494/L405 (2017+) |
| TOPIx | All model years (VIN spec sheets + module linkage) |
| DOIP VCI | Required for 2017+ vehicles using Gateway Modules |
For example, adding Adaptive Cruise Control (ACC) to a 2018 Range Rover Sport requires VCI + Pathfinder + VIN-enabled login + radar ECU flash.
Testimonials
What Our Clients Say
As a garage in Algeria, we used LR Retrofit’s SDD setup. Now we flash KVMs and program HVAC units weekly. Performance and support have been top notch.
VDIs didn’t know how to code cameras on our Velar. We installed their Pathfinder kit, updated the BCM, and now it works perfectly. Game changing setup.
We sourced a used ECU from a Dubai salvage yard. These guys helped install DOIP Pathfinder with VIN unlock + sync. Saved us $1,000+
