CAB 33 code at start up


Just means there is a fault in the body controller. Could be a billion different things. If no CEL or SEL it’s really not a big deal. Could be something as simple as a clearance light out on the trailer or the 12v power outlet can’t see ground for a millisecond because the computer was still booting up.
