Shipping Mode

By definition, shipping mode is when the Ignition Off-Draw (IOD) fuse is removed from the vehicle. The Body Control Module (BCM) receives its primary power feed from the battery via the IOD fuse. The BCM also receives a back-up power feed from the ignition Run/Start signal. During shipping mode the illuminated entry, courtesy lamps, key-in lamps, reading lamps and glove box lamps will not operate until the IOD is reconnected or the ignition switch is turned to the run/start position.
