ECU Reset The service "ECU reset" is used to restart the control unit (ECU). Depending on the control unit hardware and implementation, different forms of reset can be used: 0x11 01 Hard Reset simulates a shutdown of the power supply. 0x11 02 key Off-On Reset simulates the drain and turn on the ignition with the key.
An automotive scan tool (scanner) is an electronic tool used to interface with, diagnose and, sometimes, reprogram vehicle control modules.
