Good afternoon Folks!
I am looking for some mechanical/electrical advice from the head honcho mechanics on the boards. Here's my dilemna.
My truck is due for a smog check at a "Star" center. No big deal. I head over to a local shop and present my registration paperwork. He replies and says "No problem, should take about 10-12 minutes." Cool, thank you!
He walks up a few minutes later and tells me that his computer wont "Connect" to the vehicle's computer via the OBD-II input plug. He said he tried several times, but couldn't get the smog computer to talk with the vehicle's computer. He then takes one of his scanners out, plugs the scanner into the same OBD-II port, and the scanner is able to talk with the computer in the truck. He then tries the smog computer again with no luck. I found this odd because I haven't had any issues with the truck with regards to passing smog nor have I had any issues with the computer. I had the truck smogged two years ago without any issues.
He then backs my Suburban out of the bay and pulls a Cadillac sedan into the same spot. He takes the same smog computer plug and his PC is able to talk with the vehicle's computer. He did this just to make certain it wasn't an issue with his computer. He then backs the same Cadillac out and pulls my Suburban back into the bay. Once again, his computer is unable to connect or talk to my vehicle's computer. He backs my truck out and says it may be an issue with the OBD-II port.
He didn't charge me for the 20 minutes I was there, and said I may need to have the computer reflashed or possibly the OBD-II port replaced.
I checked the fuse that's inline with the cigarette lighter plugs on the dash because I know that might pose a problem with the OBD-II port. The fuse seems to be OK. Can you think of anything else I should look for???
Thank you for the help!!
