The invention relates to a circuit fault detection system and method and a vehicle. The circuit fault detection system comprises a first voltage division module which is connected to a power supply voltage end, a grounding end and a first end of a detected circuit; the second voltage dividing module is connected to the grounding end and the second end of the tested circuit; the first measuring module is used for measuring a first voltage value of a first voltage dividing point of the first voltage dividing module; the circuit fault detection system is configured to determine the fault type of the detected circuit according to comparison between the first voltage value and one or more preset voltage ranges, and the one or more preset voltage ranges are related to the voltage dividing structures of the first voltage dividing module and the second voltage dividing module and the position of the first voltage dividing point in the first voltage dividing module.
