Effortlessly flash and program control modules on JLR vehicles from MY2017 to MY2025. This functionality is critical when replacing ECUs, updating existing module software to fix bugs, or enabling new features. JET Master manages the entire flashing process securely via an ENET cable, providing a stable and fast connection that is superior to older J2534 devices.
Go beyond generic OBD-II scanners. JET Master reads proprietary JLR fault codes from every module in the car, giving you a complete and accurate picture of the vehicle's health. You get detailed code descriptions, helping you pinpoint the root cause of an issue quickly and avoid unnecessary parts replacement.
This is one of the most powerful features of the JET Master. The CCF holds all the customizable parameters for a vehicle. With our tool, you can modify these parameters to:
A vital function for locksmiths and workshops. The JET Master provides a secure and reliable method for programming new keys. Crucially, it supports “All Keys Lost” (AKL) situations, allowing you to generate and program new keys even when the owner has no existing keys, saving them a costly trip to the dealer.
The JET Master is loaded with dozens of special functions that streamline common and complex tasks. These include ECU renewal (virginizing used modules to be programmed to another car), transport mode activation/deactivation, service interval resets, and calibrations for various systems after component replacement.

JLR Pathfinder is the official dealership diagnostic system. It requires a continuous internet connection to JLR's servers and an expensive official VCI (Vehicle Communication Interface). JET Master is an independent, aftermarket engineering tool that performs many of the same coding and programming functions offline, without the high subscription costs and hardware requirements. For some of the very latest 2024-2025 models, some functions may still require a TOPix Cloud session, but JET Master covers the vast majority of needs for most workshops.
You need a standard Windows laptop and a JLR ENET Cable. We recommend using a high-quality, shielded ENET cable for the most stable connection during programming. We always recommend JLR official JLR DOIP VCI if you want to work with SX-TOOL, SX-CAN and TOPIx cloud all software in one tool.
Yes. The JET Master Full License has the capability to handle “All Keys Lost” situations for all DoIP supported JLR models.
