The details

About the KESS3 Slave kit — Agriculture, Truck & Bus OBD

A complete KESS3 for tractors, trucks, buses and plant, ready to use: the tool with its cables and case, the Agriculture, Truck & Bus OBD protocols activated as a slave, and 12 months of Alientech’s updates and new vehicles.

What it tunes

Engine ECUs in tractors and farm machinery, trucks, vans on truck chassis, buses, coaches and construction plant.

How it connects

By OBD: through the vehicle’s diagnostic socket, without taking the ECU out. The quickest way in, on every ECU Alientech supports by OBD.

Files by MMT

As a slave, KESS3 reads and writes and its files are tuned by its master. Buy it from MMT and that master is MMT: every file is written in house in Nottingham, checked on our own rolling road and sent back through your MMT portal, ready to write.

From MMT, with the tool

  • Your first 5 tuning files from MMT
  • Full training, in Nottingham or remotely
  • WhatsApp support 7 days a week, and remote desktop support
  • Your own MMT portal to send files and download tunes

Will it read my vehicle?

Check Alientech’s vehicle list, or send MMT the vehicle or a photo of the ECU label on WhatsApp and we tell you before you buy.

Before you buy

Questions about the KESS3 Slave kit — Agriculture, Truck & Bus OBD

Who tunes the files?

MMT. A slave reads and writes; each file goes to MMT through your portal, is written in house in Nottingham and checked on our own rolling road, and comes back ready to write. You need no tuning software or calibration skills.

What else do I need to use KESS3?

A Windows laptop with Alientech’s software, an internet connection to send files and stable power for the vehicle or ECU while you read and write. MMT sets the tool up with you and trains you on it.

Will it read my vehicle?

Alientech’s vehicle list names the ECUs it reads and how. Quicker still: send MMT the make, model and engine, or a photo of the ECU label, on WhatsApp, and we check it before you buy.

Can I upgrade from slave to master later?

Yes, one protocol group at a time, on the same tool. Send MMT your tool’s serial number and we quote the upgrade.

What happens after the 12 months of updates?

The subscription is renewed each year to keep receiving Alientech’s updates and new vehicles, through MMT as your dealer. Renew before it has been expired for 60 days: after that Alientech adds a realignment fee.
