KESS3 OBD, Bench & Boot

OBD

For supported vehicles, KESS3 can communicate with the control unit through the vehicle's diagnostic connection, providing a convenient method of reading and writing without removing the ECU or TCU.

Bench

Bench communication allows supported control units to be accessed directly outside of normal OBD communication, without necessarily having to open the ECU.

Boot

Boot mode provides direct access to supported control units where this method is required.

The available communication method depends on the vehicle, ECU/TCU and protocol supported by Alientech.
