i bought an innova 1303 scan tool, did update, upgrade for abs. Tool says unable to establish a link with vehicle. It said this before i updated the tool also. is there a password on my vehicles computer or something? Code reader works on my dads dodge so i'm assuming it isn't the problem.
According to the website it is a compatible scanner for this pickup. And yes I do have the key on. It doesn't seem to work with the engine running either.
It will not link properly with the engine running. Try a DTC reader from a local parts store to see if it is the fault of the scanner or truck. This will eliminate whether the scanner you purchased is a bum tool or not.
To piggyback on ToMang's post-I have a Scantool that works great with several vehicles so far, but it is very limited when it comes to Power Strokes. Did finally get it to connect to my PSD, but about all I got were a couple of things like engine rpm. I did have some trouble establishing communication, which I don't normally have with other vehicles.
