⚠️ Requires a Kess3 Slave Alientech device that has already been activated.
This product is a software extension, not a device.



Activation of Bench and Boot protocols for KESS3 Slave covering boats and jet-skis.
Bench mode reads and writes the control unit by connecting directly to its connector. Boot mode reads and writes by connecting to specific points on the circuit board. This activation covers Bench and Boot access on this vehicle range, from older to the latest powertrains.
In Slave version, read files are encrypted. The modified calibration map is provided by your reference Master.
Control unit removal is sometimes the only viable access route on a marine powertrain, as the installation is often difficult to reach.
A Bench power supply and the adapters for the control units being programmed are required.

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.

This product only covers Bench-Boot mode. Compare with OBD-only mode or the complete pack below before ordering.
OBD read mode
Covers only OBD mode for Boats/Jet-skis. Sufficient if you almost always work from the diagnostic socket, without removing the ECU.
Calculators deposited: this product
Necessary for cloning or for the most secure calculators that require Bench or Boot intervention.
OBD + Bench-Boot
Combines both modes for Boats/Jet-skis at €690.00 excluding tax, cheaper than buying them separately (€980.00 excluding tax).
Activation is performed remotely on your KESS3 Slave device, via your Alientech ID, within 24 to 48 hours after your order.
No, activation is permanent for the Car/LVC category and OBD-Bench-Boot mode. Only vehicle compatibility updates are covered for 12 months, then renewable.
Yes, each category and mode can be ordered separately or as part of a pack. You can complete your KESS3 Slave as your business grows (Motorcycle/Quad/UTV, Agriculture/Heavy Duty/Bus, Boats/Jet-ski).
No, this is a software extension: it requires a KESS3 Slave Alientech device that you already own and that has been activated.
Yes, by ordering "OBD Protocols - Boats/Jet-skis" (590.00 € excl. VAT) separately. You can also check if the complete Boats/Jet-skis OBD-Bench-Boot pack (690.00 € excl. VAT) is more advantageous for your needs.
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.
