⚠️ Requires an already activated Kess3 Master Alientech device.
This product is a software extension, not a device.



Activation of OBD protocols for KESS3 Master covering agricultural machinery, heavy-duty vehicles and buses.
OBD mode reads and writes control unit data via the vehicle's diagnostic port, without removal. This activation covers OBD access on this vehicle range, from older to the latest equipment.
On industrial vehicles and agricultural machinery, OBD access avoids the downtime associated with control unit removal. This is a decisive argument for fleet operators or during harvest season, where every hour of downtime costs more than the job itself.
In Master version, read files can be modified in-house or sent to a tuner of your choice.
Diagnostic connectors on this segment are predominantly proprietary round formats. Source the appropriate cables for the brands you work on: DAF, MAN, Scania, Iveco, Volvo, Renault Trucks, John Deere, Fendt, Massey Ferguson or CNH.

Yes, each category and mode can be ordered separately or as a pack. You can complete your KESS3 Master as your activity develops (Motorcycle/Quad/UTV, Agriculture/Heavy Duty/Bus, Boats/Jet-ski).
No, this is a software upgrade: it requires an Alientech KESS3 Master device that you already own and that has been activated.
Yes, by ordering "Bench-Boot Protocols - Agriculture/Heavy Duty/Bus" (2,490.00 € excl. VAT) separately. You can also check if the complete Agriculture/Heavy Duty/Bus OBD-Bench-Boot pack (3,390.00 € excl. VAT) is more advantageous for your needs.
This is the equivalent of that protocol, but extended to all vehicle categories (Cars/LCVs, Motorcycles/Quads/UTVs, Agriculture/HGVs/Buses, Boats/Jet Skis) for the chosen mode.
