Purpose & Audience

This diagnostic cable connects a laptop to Fiat and VAG-group vehicles using the KKL 409.1 protocol. It is intended for technicians and enthusiasts who need to read and clear fault codes from multiple electronic control units through a single OBD connection.

Selector Switch

A four-position rotary switch selects the target ECU: position one for the engine, two for the airbag, three for the ABS and four for the ESP system. This hardware selector replaces the need for multiple dedicated cables when working across those four modules.

Sustained Operation

The FT232RL USB-to-serial bridge draws power from the host computer and maintains a stable K-line link during extended scanning sessions. Driver support for Windows XP, Vista and 7 ensures the connection remains reliable throughout long diagnostic procedures without signal dropout.

Questions about this item

How does the 4-way switch change what the cable can read on my car?

The rotary switch selects which electronic control unit the K-line talks to: position 1 targets the engine ECU, position 2 the airbag ECU, position 3 the ABS ECU and position 4 the ESP ECU, letting you read and clear fault codes for each system in turn.

What does the 409.1 label mean for software compatibility?

409.1 identifies the VAG-COM KKL interface revision this cable implements, so it works with diagnostic packages that expect a 409.1-compatible K-line adapter such as VAG KKL 409.1 software and Fiat ECU Scan.

What physical connectors and power does the cable need to operate?

One end plugs into a USB port on a Windows XP, Vista or 7 laptop using the supplied FT232RL drivers on CD, the other end plugs into the vehicle's OBD-II socket, and the car's ignition supplies power to the interface.
