Code Scanner Not Linking.
 

I purchased a code scanner(Autel maxiscan MS409 OBD2) so I can pull the codes from my 2003 Silverado. When I connect and turn on the key I get an error message saying that I have a linking error. The new scanner works on other vehicles without a problem. Also I already tried another scanner on my chevy, still no luck. My question is ...has anyone else had this linking error and what did you find to be the problem. Thanks in advance. :cool:

sounds like you blew the fuse for the interface....usually it it the same fuse that the lighter uses

Or power port uses.

LOL yeah thats what I meant......Im old school and call it a lighter still :D

Thanks crisbmo,you may be right. The power port has never worked.Now to find the right fuse. I believe that I checked them all in the past, is there something I'm missing?

should be in th fuse box and if im not mistaken its only a 5-10 amp fuse......but it should be labled. I would use a test light to check both sides of all the fuses and look under the hood in the power distribution box also

OK Thanks I'll keep looking. :confused:

If the fuse is good, then the cig lighters is gonna be the problem. The OBII port is powered by this in series.

Thanks roughneck, I'll check them.

Looks like the cig lighter above the ash tray is in rough shape. I'll start with that one. Won't be till the week end. Thanks again.
