We have updated our Bartec 400SD and now it talks about making sure the main/second switch is in the same position as the tool. Don't see anything on their website about it, I have seen some posts here the refer to it, but I'm still in the dark. Are we talking about making sure the reset switch is not or should be held while programming? Just trying to be up on things before we have a car in the bay. Cuz I just scanned the other tech's wife's van and it has 2 dead sensors, and the tape fell off the dash.....
