2024 KESS3 ECU Programmer FAQ & Customer Feedback
KESS3 Frequently Asked Questions:
1. How can I interface and program the control units?
With KESS3 you can program the engine control units (ECU) or transmission control unit (TCU) in three different ways:
OBD – With the OBD mode, you can easily access all the ECU data through the diagnostic socket.
BENCH – With the Bench mode you can access the ECU data directly from the connector
BOOT – With Boot mode, with the engine control unit opened, you could connect directly to all the memories of ECU/TCU.

As a Master user, you can read the files in clear. This allows you to operate independently in order to remap and reprogram the ECU with modified files.
