First thing that needs to be done is to find out the real DTCs the car has stored, with a dedicated scan tool. The car doesn't set those codes. I'd wager the Hum module has a software glitch, or something is getting corrupted by the module itself, or in its transmission to Verizon HQ. One more reason not to use aftermarket components that can send data like this. It'll be great when OBD3 gives you a citation or puts your car in limp mode for a load of DTCs that aren't really there.Start with https://www.cruzetalk.com/forum/25-...al-coverage-14311-negative-battery-cable.html and then clear the codes. If they come back then start with the first code to be displayed.
