    Just curious here. When I get in my T660 and insert key and turn to the right, and before i engage the starter, what is the truck doing during its "preamble", for lack of a better word? I hear some funky servo sounds and the brakes purge themselves or something. I usually wait for it to complete before cranking. On my personal diesel car I always wait for the glow plug light to go out, but it only takes a second or 2.
    Thanks!

    Thanks snail. Is it doing any harm if I crank it before it finishes everything?

    Yes it will start causing problems. I created a situation with mine where the lights wouldn't shut off.
    Not allowing it to run thru the process is the same as your laptop booting up with out all the files loading.
    It might not happen right away but, eventually you'll start having issues
