    Default Park assist service

    Hello everyone
    I have a 2007 GMC Sierra 2500HD Turbo Diels had it for about 6months now everything was fine untill now. The display shows service park assist, needless to say it doesn;t work it did but not now, checked all the fuses they are fine cleaned all sensors, so what else can I check before I have to take it to the dealer

    Welcome to the site! I can't help with the park assist, but hopefully one of the resident gear heads can.

    If you have a hitch, remove it and drive over 15mph and see if it then starts to work again. I know that on my silverado when you put a hitch on it, it disables the park assist and once removed you need to drive faster than 15mph for it to re-enable. Hope this helps.
