OBD II scanner/ Check engine light

[KiDD QuE]

I have a check engine light on in my truck. I took it to autozone and he said that my OBD port isnt powering his machine. He said that it could be cause of a bad fuse. I checked the fuses in the cab and they were all fine. Have any of yall experienced this problem? I drive a 2000 f250.

I always forget where But, in one of the corners of an OBD-II port is +/- You can safely take a meter and probe those holes to see if any have power there. Also look at the pins inside they often have corrosion because they're above the throttle pedal and "scraped" by a wet, dirty, shoe.

Bad News though, AutoZone's scanner isn't meant for your truck and not able to properly scan the truck anyway... They should be able to connect though and it sounds like they Did identify a problem
