Toyota/Lexus owners or technicians, this Mini VCI J2534 cable lets you connect your laptop to your vehicle's OBD2 port for advanced diagnostics and programming. It's compatible with Toyota's TIS Techstream software and supports protocols for vehicles from 1996 onward. You can read/clear codes, perform adaptations, program keys, flash ECUs, and more. The latest version is V18.00.008 with firmware V1.4.8 – make sure you get the updated software from the seller. It works best on Windows 7 32-bit systems; it might work on Win 8/10 but can be finicky. Important: you'll need to disable antivirus software during installation, as it often falsely flags the diagnostic software. The cable itself is compact and plugs into USB. This is a professional-grade tool for serious DIYers or small shops. If you're tired of generic code readers and want factory-level access, this cable is a cost-effective solution. Just be prepared for some setup and ensure you have the correct Techstream software. A powerful tool for the price.
