KESS3 combines OBD, bench and boot communication with Alientech Suite. The manufacturer lists ECU, transmission, after-treatment and urea-dosing control units across several vehicle classes, subject to the selected licence and protocol.
Connection modes
- OBD uses the diagnostic socket.
- Bench connects to a supported control unit through its connector without opening it.
- Boot provides access using an opened control unit where the protocol requires it.
Configuration and workflow
Master users can prepare files independently; Slave users exchange files with their linked Master. Protocol packages cover different modes and vehicle classes. Alientech also describes DTC, DataLogger and DynoDrive features, with availability depending on vehicle and configuration. Read the current vehicle list and protocol manual for supported operations, cables and subscription requirements. A virtual read is not the same thing as a full physical backup.
