If you want to reset the computer, just remove the neg. battery cable for a few minutes.

Can you describe the problem a little bit more, or did you fix it already?


Also, where are you from friend?

with obd 2 you reset it by removing the code with a scanner. others just pull the positive cable from the battery for 30 mins to reset everything.

it went away by it self
