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



Activation of Bench and Boot protocols for KESS3 Master covering agricultural machinery, heavy-duty vehicles and buses.
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 equipment.
Heavy-duty and agricultural control units are large and use specific connectors. Bench work is essential for locked units and for control unit repair and replacement operations.
In Master version, read files can be modified in-house or sent to a tuner of your choice.
The Continental HDEP MCM2.1 cable (ref. 144300K275), Temic ACM2.1 cable (ref. 144300K276) and TRW heavy-duty adapter (ref. 14AM00T13M) cover the most common control units on this segment.

ECUs in exchange: this product
Required for cloning or the most secure ECUs that require Bench or Boot intervention.
OBD + Bench-Boot
Combines both modes for Agriculture/Heavy Duty/Bus at €3,390.00 excl. VAT, cheaper than purchasing both separately (€5,480.00 excl. VAT).
Activation is performed remotely on your KESS3 Master device, using your Alientech ID, within 24 to 48 hours after your order.
