How can you 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.

Alientech supports hundreds of thousands of vehicles. Not only engine control units, but also transmission control units equipped on cars, motorcycles, tractors, trucks and boats. To know all the vehicles that Alientech supports, you can easily consult vehicle list.
