    G21 port NSS overcurrent fault

    I am getting a port NSS overcurrent fault on my G21. Every time I try to reset the fault with in 2-3 seconds it trips again. It does this when I am not even trying to use the NSS system. Has anyone else have this problem? Only thing I have found about it is a guy accidentally nicked one of his wires installing LED lights but I haven’t done anything of that nature. Called around to a couple of dealerships they said it was an update that needed to be done. They sent me flash drive did the update and still have the fault. Please help thanks
