Alientech KESS3 Slave Bike Bench-Boot + OBD

The Alientech KESS3 Slave Bike Bench‑Boot + OBD isn’t standalone hardware — it’s a software activation bundle for the Alientech KESS3 tuning tool. It enables your KESS3 interface to communicate with bike, ATV, and UTV ECUs using both:

• OBD (via diagnostic port), and

• Bench and Boot modes (for deeper access where OBD isn’t available).

To use it you generally need:
✔ A KESS3 hardware interface
✔ The corresponding Alientech Suite software installed on a PC
✔ The specific protocol activations (like this product) assigned to your hardware serial.
Many sellers provide activation based on your tool’s serial number.
