Alientech KESS3SA003 KESS3 Slave Agriculture Truck & Buses OBD Protocols activation

This activation unlocks OBD (on-board diagnostics) protocol support for:

• Agriculture vehicles (tractors, harvesters, etc.)

• Trucks

• Buses

That means the KESS3 Slave tool can communicate with these vehicle ECUs over the standard OBD diagnostic port for reading and writing ECU data — but only for the specific models covered in this group.

Subscription Updates

Many sellers include a 12-month subscription with updates to the protocol list, ensuring ongoing compatibility with new vehicles and ECUs.
