Alientech – KESS3SA012 – KESS3 Slave – Agriculture – Truck & Buses OBD-Bench-Boot Protocols activation “Bundle”

This product is a software activation bundle for the Alientech KESS3 Slave ECU tuning interface. It does not include the physical KESS3 hardware — it’s the license pack that unlocks specific ECU communication protocols on your existing tool.

This bundle enables the following modes for tuning supported ECUs in agriculture vehicles, trucks, and buses:

1. OBD Mode (On‑Board Diagnostics)

   • ECU read/write via the vehicle’s standard OBD port.

   • Useful for vehicles where the ECU supports OBD tuning without opening the control unit.

2. Bench Mode

   • Direct ECU access via hardware (ECU removed from vehicle).

   • Tuning performed by connecting to ECU connectors on a workbench.

3. Boot Mode

   • A low‑level access method to read/write ECUs that may not support standard OBD.
