Alientech KESS3SA001 KESS3 Slave Car LCV OBD Protocols activation

It’s a software license activation for the Alientech KESS3 Slave ECU tuning tool that enables OBD protocol support for Cars and Light Commercial Vehicles (LCV).

With this activation, your KESS3 Slave unit can communicate with vehicle ECUs through the OBD port to read and write data for tuning purposes.

The activation includes a 12‑month subscription for updates, keeping your tool compatible with newer vehicles released during that period.

This is a software license only — the KESS3 hardware must already be owned separately.
