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



Protocol pack for KESS3 Slave covering passenger cars and light commercial vehicles, combining OBD, Bench and Boot communication modes.
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 vehicles.
In Slave version, read files are encrypted. The modified calibration map is provided by your reference Master. This setup allows a workshop to carry out all on-vehicle operations independently, without bearing the cost of a Master licence or developing in-house calibration expertise.
The car and LCV segment offers the widest availability of calibration maps from tuners.
Ensure you have identified your reference Master before purchasing: a Slave device is only operational when paired with a Master that supplies the modified files.

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 Car/LCV category. This product corresponds to the complete pack, highlighted below.
Quick Interventions
Sufficient if you almost always work through the diagnostic port, without removing the ECU.
ECUs removed
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 cars/light commercial vehicles.
Activation is performed remotely on your KESS3 Slave device, using your Alientech ID, within 24 to 48 hours after the order is placed
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 each mode can be purchased separately or as part of a pack. You can complete your KESS3 Slave as your activity progresses (Motorbike/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 have activated.
This package combines both: you don't have to separately purchase the OBD protocol (€1,290 excl. VAT) and the Bench-Boot protocol (€990 excl. VAT) for the same category.
This is the equivalent of that protocol, but extended to all vehicle categories (Car/LCV, Motorcycle/ATV/UTV, Agriculture/HGV/Bus, Boats/Jet Skis) for the chosen mode.
The protocol content (vehicles and modes covered) is identical; only the product reference changes depending on the version of your box.
