KESS3 combines 3 operating modes in one tool. OBD, Bench and Boot Mode. KESS3 is the successor of Alientech’s popular KESSv2 and K-tag tools. With the KESS3, Alientech has combined the KESSv2 and K-TAG tool in one tool, so you don’t have to purchase two separate tools to be able to use multiple read methods.

All in One - OBD, Bench and Boot mode.
  • OBD Mode
  • With the OBD mode, you can easily access all the ECU data through the diagnostic socket.
  • BENCH Mode
  • A simple interface for the connector and you have complete access to the data of ECU

  • Subscription & protocol changes
Alientech has made changes in their subscription structure because they wanted to simplify the structure in order to meet customers needs in a better way. Therefore, they decided to separate the subscriptions, so customers now are able to choose one particular category of vehicle and still are able to combine them.
