What to Do When the Engine Warning Light Comes On

Model: (Various brands) Various
Part: Warning light – error code

Video tutorial

In this video, you can see how to reset the engine control light and how to reset it after repairs. The best method is to use an OBD2 scanner, connecting it to the EOBD port; read the error code, repair the fault, clear the code with the scanner, and the light will turn off. You can also try disconnecting the battery: disconnect the negative terminal and leave it disconnected for half an hour.

However, this will also reset the radio, clock, and electronic memories. On modern cars, there is the ignition cycle method: insert the key and turn it to ON for 2 seconds, then to OFF for 2 seconds: repeat this about ten times until the light turns off. It only works if the problem is resolved and the ECU has completed its diagnostic tests.

On cars with self-diagnosis, simply drive 50/100 miles in mixed conditions after resolving the issue: the light will turn off automatically.
