Abstract

The invention provides an automobile wire harness short circuit and overcurrent test system which comprises a vehicle-mounted electric appliance, two ends of the vehicle-mounted electric appliance are correspondingly connected with electronic loads, and a connecting line between the vehicle-mounted electric appliance and the electronic loads is connected with a deconcentrator used for detecting short circuit and overcurrent of a detected loop. The deconcentrator is connected with a data acquisition module used for acquiring data information of a detected loop, and the data acquisition module is connected with a control module used for controlling on-off of the deconcentrator. The two ends of the vehicle-mounted electric appliance are further connected with a power module used for supplying power to the vehicle-mounted electric appliance and the electronic load. According to the automobile wire harness short circuit and overcurrent testing system and method, automatic testing of automobile wire harness short circuit and overcurrent is achieved, reliability and convenience of automobile wire harness short circuit and overcurrent testing are improved, testing efficiency is improved, and safety risks caused by wiring errors possibly existing in the testing process and wire harness spontaneous combustion are effectively avoided.
