USB OBD2 Diagnostic Cable for ECU Scanning

This USB OBD2 diagnostic cable connects a vehicle's diagnostic port to a computer for ECU scanning and trouble-code reading. It uses an FT232RL chip and a 4-way switch to access different electronic control units. The translucent blue housing protects the electronics while remaining compact at 1.0 in height. A software CD is included for installation on supported Windows systems.

Suits DIY owners and mechanics using older Windows

The cable works with diagnostic packages such as Fiat ECU Scan and KKL V-ag 409.1 on Windows 98, ME, 2000, XP, Vista and 7. It targets vehicles from 1996 onward with standard OBD2 sockets. Users needing support for newer Windows versions, wireless connectivity, or manufacturer-specific protocols not covered by the included software should consider other tools.

FT232RL chip with 4-way ECU selection switch

The FT232RL USB-to-serial bridge provides the communication link between the laptop and the vehicle. A physical 4-way switch on the cable selects the correct ECU pathway without software reconfiguration. This hardware switch is the decisive feature for technicians who must toggle between multiple control modules during a diagnostic session.
