my OBD hookup is not talking to ANY scanners whatsoever, i have no idea why as everything seems to be hooked up correctly yet no matter whats trying to read it nothing gets through no store scanner no modis scanners and i cant pass emissions because even theirs cant get any sort of reading, it did work before because i have had it scanned by someone with a snap on modis to see what was causing a misfire about half a year ago if i understand things correctly my computer is working because the truck does run fine (most of the time lol) any directions i should head in or somewhere i should start poking at? it seems like its always something or another because on top of this issue my caliper locked up today lol any advice would be great because i have to pass emissions this month some time

 

I believe most obdii data links are configured the same so do you have voltage at pin 16? lower left cavity of the link.

 

let me go check

 

provided i am doing everything correctly to test it, no i am not getting voltage out of that particular one

 

there should be a fuse for the obd II port.if the fuse is blown it wont send of recieve anything...

 

That was with key on? Then you need to get a wiring diragram and trace that wire back to the pcm and check there.

 

yes key was on sir, where would i find this fuse? the dash is apart would some corrosion on these connectors have anything to do with it? i could give them a quick scrub

 

the key does not have to be on for the scanner to come on. if i plug my scanner in it turns on automatically. of course the key has to be on for the scanner to read the codes and i/m monitors.

 

the fuse should be in the fuse box on the side of the dash, if its not it will be in the fuse block under the hood...

 

Battery powered scanner maybe? Ill go check mine to confirm this. If it was a fuse thats great. kiss lol
