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



Activation of OBD protocols for KESS3 Slave covering agricultural machinery, heavy-duty vehicles and buses.
OBD mode reads and writes control unit data via the vehicle's diagnostic port, without removal. This activation covers OBD access on this vehicle range, from older to the latest equipment.
In Slave version, read files are encrypted. The modified calibration map is provided by your reference Master.
This configuration suits workshops that carry out on-site work at operators' or hauliers' premises: reading and writing is done on location, with the calibration map prepared by the reference Master.
Connectors on this segment are proprietary. Source the appropriate round cables for the brands present in your area.
