What is the simplest way to reset a car's ECU?
1 Answers
Drive for a while to allow the car to reach normal operating temperature, then park and turn off the engine, shutting down all electrical devices in the car. Open the car's hood, locate the battery, and disconnect the battery's power cables. Wait for 10 minutes before reconnecting, then turn on the power without starting the engine and activate the car's electrical devices, waiting for 30 seconds. Remove the key, and the reset is successful.
