How do you reset engine management system fiat punto?

To reset the engine management system in a Fiat Punto, you can disconnect the car battery by removing the negative terminal for about 15 minutes. This will clear any stored fault codes and reset the ECU. After reconnecting the battery, start the engine and allow it to idle for a few minutes to enable the system to recalibrate. Alternatively, using an OBD-II scanner can also clear fault codes and reset the system more efficiently.
