The ECU is one of the most important components in your car. If there are errors or malfunctions, you can resolve them with a simple reset. This operation cannot be done through the onboard menu; you need to intervene manually.

First, ensure the car is completely off and parked safely on a flat surface. Next, lift the hood and locate the ECU on the right side of the engine compartment.

Disconnect the safety pins, remove the ECU, and reposition it correctly after waiting a few seconds to complete the reset.
