No only the first time I try to connect after the truck sits a while. I cycle the Tech2 off and back on then immediately go through the procedure. The message does not return the second time and diagnostic functions of the tech2 work as expected.
I will look into that. The issue I have first is that it is a temporary problem that goes away the second time I connect the tech2. I may just unplug the VCIM and see if it goes away.
you can run a test on all the modules to check for dtc's review them all then clear them all and restart and shut off the truck and see what comes back as current or open. whatever is open/current is what you will want to address. what I do is write down the historical codes and then clear everything and if nothing comes back right away then I just wait a few days and then check again to see if it ends up coming back. This tells me if something is intermittent or not, it can also see the mods I have done like adding led strips or connecting my puddle lights to the interior lights it shows it as "a short to ground" which does not affect anything it just see's the ground I added. If that showed up on something else that I had not done anything to then I know that particular module or section has a problem.
on my 2012 I had a short somewhere which I think is under my fuse box, I had a code come up for a short in the lan and it really wouldn't work right, after I wiggled the wires under the fuse box and zip tied them up where they should be (mine had come off the xmas tree holder and were dangling) then the short went away and everything communicated properly again. I wanted to replace the harness that goes from the main wiring harness to the bottom of the fuse block but they only sell the harness connector and not the pig tail.
