How do i reset the engine management light on my 2003 ford focus?
Answers:
Look on the manual for the ECC fuse and take it out for a minute, then put it back in.
That will reset the computer.
Notice that the computer will have to "re-learn" many driving conditions and the car might feel a bit strange for a while until it learns it all again. Depending on driving conditions, could take from 10 minutes to a couple of hours.
Take it to a dealer.
I have always unhooked my battery for about 20 minutes.Hook it back up and take your car out for a good long drive on the highway.This will reset your computer on your car.Trust me this will work,you dont need a mechanic.
needs resetting with diagnostic equipment, most decent garages should be able to do this.
taking the battery off does not work on these cars
