Why Reset the Engine Control Units?
Engine control units (ECUs) are complex systems that use algorithms and data maps to control engine performance. When a part is replaced, the engine control units may need to be reset to account for the new characteristics of the replaced part.
Reset Procedure

Consult the manufacturer’s manual: Before starting, check the manufacturer’s specific instructions regarding the reset process. Each vehicle may have particular requirements.
Use a diagnostic tool: You need a diagnostic tool compatible with the vehicle to access the engine control unit (ECU). This tool allows you to connect the ECU to the system and initiate the reset.
Select the reset function: After connecting the diagnostic tool, select the option to reset the engine control units. This will erase old configurations and error codes.
Follow the instructions: The diagnostic tool provides step-by-step instructions to complete the reset. Follow them carefully to avoid any issues.
These steps ensure that you carry out the process correctly and return the vehicle to its optimal performance after the reset.
