Follow the instructions here: https://www.mustang6g.com/forums/showthread.php?t=67564Hey all, 2 quick question for all the more knowledgeable folks. Plz help if u can.
1. I changed my speedo calibration using forscan and everything actually works great. I'm maybe fractions of a mph off. But... I was just checking out the DTC codes or whatever and noticed I had a P104A code (I think that was it) and tried clearing but it came back. It does not turn on light on dash but wanted to make sure I shouldn't do something or check a real thing out lol safety first!
