Alientech – KESS3SA013 – KESS3 Slave – Marine & PWC OBD-Bench-Boot Protocols activation “Bundle”

It’s not physical hardware — this is a software activation/license that you apply to your existing KESS3 Slave device.

Once activated, your KESS3 Slave can communicate with supported marine & PWC ECU types using all major tuning methods:

• OBD (On‑Board Diagnostics): flash/read through the vehicle’s OBD port.

• Bench mode: read/write when ECU is removed from the machine.

• Boot mode: low‑level access for ECUs requiring direct boot communication.
