i just need to know how to completely disconnect the battery from my car...i am just gonna have it undone for like 20 minutes. people said it was reset my ECU and thats exactly what i need it to do? help please!
take of the (-) batt cable (NOT THE RED ONE) and pull it completely away from the post. Use a 10MM socket to losen the bolt. It won't come off. Its tight so it will be a little difficult. Thats all you need to do to reset the ECU. Leave that off... turn on your headlights and insert the key and turn to the ON position to drain all the juice hidden in various capacitors and you'll be all set after a few minutes.
