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

The three formats exist for the Agriculture/Heavy Goods Vehicle/Bus category. This product corresponds to the complete pack, highlighted below.
Quick interventions
Sufficient if you almost always work from the diagnostic socket, without removing the ECU.
ECU Removed
Required for cloning or the most secure ECUs that require a 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 Slave unit, using your Alientech ID, within 24 to 48 hours after your order.
No: activation is permanent for the chosen category and mode. Only vehicle compatibility updates are covered for 12 months, then renewable.
Yes, each category and each mode can be ordered separately or in a pack. You can complete your KESS3 Slave as your activity progresses.
No, this is a software upgrade: it requires an Alientech KESS3 Slave unit that you already own and have activated.
This bundle includes both: you don't have to buy the OBD protocol (€1,290.00 excl. VAT) and the Bench-Boot protocol (€990.00 excl. VAT) separately for the same category.
This is the equivalent of this protocol, but extended to all vehicle categories (Cars/LCVs, Motorcycles/Quads/UTVs, Agriculture/Heavy Goods 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 device's version.
