truck wont scan

[ocelot]

so i was driving home yesterday and the check engine light came on, so i stopped at the local checker auto and asked to have my truck scanned. Well after a dozen attempts to scan it no luck, so the guy expressed that it was the plug on my truck that when bad, i really don't see that happenings so i wanted to get a second opinion on this. Should i try another place has this happened to someone before? I really want to find out the code its throwing so i dont fubar my truck. btw its a 1997 tahoe

Try at least two if you can.

Check the fuse. If it's blown, the truck won't communicate via the ALDL connector.

*update* checked fuses and all are in working order going to auto zone tomorrow for a second opinion

In addition to the fuse mentioned above, the problem could be a communication issue between the scanner/cable and the ODB2 port. I had that happen once, too.

so i got a second scan and still no luck i think im going to clear the system the old fashion way and have the whole system reboot what do you think?

i know u checked the fuses , but double check the cigarette lighter fuse if the if popped the obd port will not work. are u checking the fuses by sight or with a test light , u can be tricked somestimes if u aare doing it by sight

not to be a dick or anything but this belongs in general discussion, again just saying
