anybody know where I can find a reference for U DTC's for obd II?
I have a 1996 Suburban that has a U3900 and a P0711. I know what the P0711 is, but it seems that I'm the only guy on the internet (if not the world) that has a U3900 (networking error) code that will not clear. I'm stumped on this one.:o
