USB OBD2 diagnostic cable

The TaoTao KKL-4Switch connects a vehicle OBD2 port to a computer USB port for ECU scanning and fault-code reading. A built-in FT232RL chip handles the serial-to-USB conversion and the translucent blue housing shows the internal circuitry. The cable includes a 4-way switch to select between different ECU communication lines without unplugging.

For owners of 1996-on OBD2 cars needing multi-ECU

Suits DIY enthusiasts and independent workshops that use software such as Fiat ECU Scan or KKL VAG 409.1 on Windows XP through Windows 7. Not suited for technicians who require support for newer operating systems, wireless connectivity, or vehicles that use diagnostic protocols outside the KKL 409.1 standard.

Plugs into OBD2 port and USB, runs from supplied CD

The adapter draws power from the USB connection so no external supply is needed. The 4-way switch frees the user from swapping cables when moving between engine, transmission, ABS or airbag modules. The package includes the cable and installation software CD for immediate setup on a compatible laptop or desktop.

Questions about this item

Which operating systems already installed on my laptop will run the FT232RL drivers on the supplied CD?

The included drivers support Windows 98, ME, 2000, XP, Vista and Windows 7.

Can I leave the KKL-4Switch connected while I also use an older serial KKL-VAG 409 interface on the same vehicle?

The cable's 4-way switch selects one ECU path at a time, so only one interface communicates with the vehicle at any moment.

How do I confirm the blue KKL-4Switch is communicating with my car's ECU after plugging it into the OBD2 port?

Open the included Fiat ECU Scan or KKL VAG 409.1 software; a successful connection screen and live parameter data indicate the link is active.
