The invention provides an intelligent power distribution module. The input end of the intelligent power distribution module is connected with a power supply, and the output end is connected with a load. The intelligent power distribution module comprises an MCU, an HSD, an eFuse and a current detection module. The MCU is respectively connected with the eFuse and the current detection module, and the MCU is used for controlling the intelligent power distribution module to transmit current to the load; the HSD is respectively connected with the eFuse and the load; the HSD is used for driving or cutting off current transmission of the load; the current detection module is used for detecting a real-time output current value output to the load, and when the real-time output current value exceeds a maximum allowable current threshold value, the intelligent power distribution module stops outputting current to the load. The invention further provides a vehicle power supply wiring harness fault diagnosis method, the situation that the wiring harness is not disconnected in time due to rapid current rising can be avoided, and the situation that the module is slowly overheated and fails due to environment changes can be avoided.
