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



Protocol pack for KESS3 Master covering agricultural machinery, heavy-duty vehicles and buses, combining OBD, Bench and Boot modes.
On this segment, demand is primarily focused on fuel consumption reduction and engine adaptation to specific use cases. Gains are measured in litres of diesel over high mileage or operating hours, delivering a fast return on investment for operators.
OBD mode reads and writes via the diagnostic port without removal. Bench mode connects directly to the control unit connector. Boot mode connects to specific points on the circuit board. This pack covers all access methods from older to the latest equipment.
In Master version, read files can be modified in-house or sent to a tuner of your choice.
This segment requires specific connection tooling: heavy-duty and agricultural manufacturers use proprietary round connectors. Check the dedicated cable range before committing to a job.

WHAT THIS PROTOCOL COVERS
Please check that the category and mode match your usage before ordering, the protocol cannot be modified after activation.

The three formats exist for the Agriculture/Heavy Goods Vehicle/Bus category. This product is the complete pack, highlighted below.
Quick interventions
Sufficient if you almost always work from the diagnostic port, without removing the ECU.
Bench-booted ECUs
Required for cloning or the most secure ECUs that require bench or boot intervention.
OBD + Bench-Boot: this product
The most common choice to avoid having to buy a second protocol later for Agriculture/Heavy Goods Vehicles/Buses.
Activation is performed remotely on your KESS3 Master device, using your Alientech ID, within 24 to 48 hours after your order.
No: activation is definitive for the chosen category and mode. Only vehicle compatibility updates are covered for 12 months, and then renewable.
Yes, each category and each mode can be ordered separately or as a pack. You can add to your KESS3 Master as your business grows.
No, this is a software upgrade: it requires an activated KESS3 Master Alientech unit that you already own.
This package combines both: you don't have to buy the OBD protocol (€2,990.00 excl. VAT) and the Bench-Boot protocol (€2,490.00 excl. VAT) separately in the same category.
This is the equivalent of this protocol, but extended to all vehicle categories (Cars/LCVs, Motorcycles/Quads/UTVs, Agriculture/Heavy Vehicles/Buses, Boats/Jet Skis) for the chosen mode.
The content of the protocol (vehicles and modes covered) is identical; only the product reference changes depending on your unit's version.
