OBD Plug no power???

Hey folks, I took my '97 ST to the DEQ emissions inspection station for its bi-annual inspection. When they plugged into the connection that allows them to read what I believe are the OBD emissions related codes and such, they couldn't do it. They told me their computer couldnt initialize communications or something.

They are guessing that there is no power at that plug. They suggested I check for a blown fuse. None of the info i have suggests there is a special fuse for it. They say many vehicles have the cig lighter tied into that but mine works fine. I have checked the fuses in the interior near that plug but all are fine. Vehicle runs great but I need desperately to pass this inspection to get my tags renewed.

Has anyone seen this problem? Is there something that I need to reset??

Any info would be greatly appreciated.

Larry

How is the truck running?

I would try and stop at an Autozone or Advanced Auto, here in Georgia, they will plug an OBD scanner in for free to check on the codes. If they are unable to get a reading, then you may want to check with a local shop or dealership.

Those guys may have just had a bad connection... Hopefully.

larry, after looking through some circuit diagrams...looks like the obd II diagnostic socket is powered by a 5 amp fuse located in the same area as the connector itself. Fuse number 3, 5 amps.
maybe there old worn out obd connector shorted the fuse when they plugged it in
let us know if this was the case

Guys, THX for the input...found the problem. There was a couple of burned out fuses in panel in engine compartment..replaced them and OBD II is happy again.
