The invention relates to the technical field of vehicles, in particular to a power-off control system and method for preventing power shortage and abnormal function display of a whole vehicle, and the power-off control system is characterized in that an external switch device is arranged on the side end face of an ignition switch lock body, and the input end of the external switch device is electrically connected with the output end of the ignition switch lock body to form a circuit on-off switch; the output end of the external switch device is electrically connected with a ground wire; the two ends of a contact pin, used for circuit connection, of the electromagnetic relay are connected with the fuse box BAT and the storage battery respectively, two coil pins used for controlling circuit connection and disconnection are electrically connected with the storage battery and the cab power switch respectively, and one pin of the cab power switch is electrically connected with the ignition switch lock body. A storage battery, an electromagnetic relay, a cab power switch, an external switch device and an ignition switch lock body are arranged in series, the output end of the storage battery is electrically connected with a combination instrument, a T-BOX, a radio and an ECU constant electric relay, the problem of power shortage of the whole vehicle is avoided, and the fault problem caused by time asynchronization and dormancy is solved.
