NOVELTY - An electric power line wired in an interior of a vehicle from a battery (3) and supplies a power to various kinds of loads of the vehicle. Several short sensors detect a short between several sections of the electric power lines (12A-H). A control circuit specifies the short section of the electric power line in accordance with a short detection condition of the short sensors.    USE - For supplying a power from a power supply, which is mounted on a vehicle of several electric loads mounted on the vehicle.    ADVANTAGE - A high reliability performance can be obtained against to an abnormality (for example, a short-circuit) of an electric power line using a wire harness having a comparative low regular current. An unnecessary load current is not flown to an electric power line and a consumption electric power can be reduced. A fuse and a relay are arranged at a vicinity of a control module and a power wiring can be shortened    DETAILED DESCRIPTION - A front integration module (FIM) (5) has a short detection circuit (130) and monitors a short abnormality of the electric power lines (12A,12H). With the short detection circuit (130), for example, when a short abnormally of the electric power line (12A) is detected, such a signal is inputted into the control circuit (170). Through an output signal line (170a) the load power supply shutdown circuit (110) is driven, and an end portion of the electric power line section (12A) having the short abnormality is contacted and separated.    An INDEPENDENT CLAIM is included for:    (a) a load control module which is installed to a specific position of a vehicle    DESCRIPTION OF DRAWING(S) - The drawing is a first embodiment of a whole system view of an vehicle to which the present invention is applied.    front integration module (FIM) (5)    battery (3)    output signal line (170a)    short detection circuit (130)    control circuit (170)    electric power lines (12A-H)    electric power lines (12A,12H)    load power supply shutdown circuit (110)
