After plugging My 2001 ford explorer sport 3 door into several sct tuners and scan tools I still can't figure out why every one of them can't read the vehicle info or Vin but with let me clear dtc if any. Also last night when heading home from a friend's I noticed the check engine light was on when I started the truck but wasn't when I parked it several minutes earlier.the weird part is that even though the check engine light was on it seemed to run better than it ever has .almost to good
