The invention provides a power line communication module for vehicle diagnosis information. The circuit comprises a controller area network transmission (CAN) high potential end, a controller area network transmission (CAN) low potential end, a positive voltage end, a grounding end and a signal conversion interface, the controller area network transmission high potential end and the controller area network transmission low potential end are used for being connected with a controller area network transmission (CAN) busbar of a vehicle. The positive voltage end and the grounding end are connected with a power supply of the vehicle; a controller area network transmission signal entering from the controller area network transmission high potential end and the controller area network transmission low potential end is transmitted to the signal conversion interface; and after being converted into a power line communication signal, the power line communication signal is transmitted to a powersupply of the vehicle through the positive voltage end and the grounding end so as to be further transmitted to at least one electronic device connected with the power supply in the vehicle.
