What you are paying for

A KESS3 is three things, priced as one kit.

01

The tool

The KESS3 hardware with its cables. On its own it reads nothing: it is the same box for slave and master, for a car or a tractor.

02

Protocols

A licence per vehicle group (cars and LCVs, bikes, agri and trucks, marine) and per connection (OBD, bench and boot). Slave or master is decided here.

03

Subscription

The period of Alientech updates and new vehicles that comes with the protocols, renewable when it ends.

Before you order

Good to know

What do OBD, bench and boot mean?

OBD reads and writes through the diagnostic socket with the ECU still in the vehicle. Bench connects to the ECU out of the vehicle, through its connector. Boot opens the ECU and connects to the board, for units that cannot be read any other way. KESS3 does all three in one tool, for the protocols that are active on it.

Which vehicles does KESS3 cover?

Protocols are sold by vehicle group: cars and LCVs; bikes, ATVs and UTVs; agriculture, trucks and buses; marine and PWC. Coverage is decided ECU by ECU, so check Alientech’s official vehicle list, or send us the ECU reference on WhatsApp and we will tell you before you buy.

Is there a subscription?

Each protocol licence comes with a subscription period that brings Alientech’s updates and new vehicles; renewals are sold separately. Every kit on this site lists exactly what is in it.

Can I upgrade from slave to master later?

Yes. Alientech sells slave-to-master upgrades for each protocol group, so the tool you start with is the tool you keep. Ask MMT when you are ready.
