02 CHEVY SERVICE ENGINE SOON LIGHT ON, NO CODE READ

2002 Chevrolet Silverado • V8 2WD Automatic • 212,000 miles

The service engine soon light came on in my 2002 Chevy Silverado 2 days ago. I took it to Autozone first to have it scanned, no scans showed up, the computer kept telling it to hook it up to the car, so it wasn't seeing it. I took it to Advance Auto and the same thing. I then went to O'Reileys and the same thing happened.

I was told it is possibly just a bad wire in there causing it to go off. Is that possible, is it just a fuse?

It may be a trans code as the auto parts stores can't read that. Have a pro read it as theirswill read abs/trans/all of them. If not it may be a broken wire or graound problem and it will have to be fixed anyhow.
