Scanner won't communicate with computer
Hey guys back again lol.
So Iam trying to run some diagnostics and get codes for my truck.
Problem is the scanner won't communicate with the trucks computer.
It's the usb elm 327connector and Iam using the forscan program.
Changed to ciggar lighter fuse. still not working. I think the previous owner had a edge program in it idk if that might of fried the pcm or is causing it not to read right ?
do I need a better connector or are the pins inside the trucks communicater bad ?
Thanks guys for any insight

Not necessarily. I have both a Bluetooth and a USB adapter, neither of which cost more than 12 bucks, and both of which have worked every time. Don't condemn the adapter until you've tried it on other vehicles.

Let me rephrase. Don't condemn the adapter until you've tried it on other pre-2004 Ford vehicles.

Well I was hoping to use it for what it's made to do. Read codes and do a buzz test. Before I get the AE I want to see if there is sowmthing wrong with my outlet plug or sowmthing else causing it not to communicate or if the usb connector is junk.
Been looking on the web and some say it could be the pcm is shot ?
How do you test the connectors/pins at the output plug for the truck? Maybe one isn't working properly ?
