Vehicle diagnosis method, vehicle diagnosis system, debugging method, debugging system, and related devices

The invention discloses a vehicle diagnosis method, a vehicle diagnosis system, a debugging method, a debugging system, and related devices, and relates to the engineering machinery field. The vehicle diagnosis method is characterized in that a vehicle debugging diagnosis module is used to acquire electrical module signals of a vehicle by a vehicle internal network; the vehicle debugging diagnosis module is used to convert the electrical module signals from the communication format of the vehicle internal network into the wireless communication format; and the vehicle debugging diagnosis module is used to transmit the converted electrical module signals to a mobile debugging diagnosis device for the diagnosis in a wireless manner. The vehicle debugging diagnosis device is used to acquire and transmit the electrical module signals by the vehicle internal network in a unified manner, and after the format conversion, the electrical module signals can be transmitted to the mobile debugging diagnosis device for the diagnosis, and in addition, the connection between the specific diagnosis device and the vehicle electrical interface is not required, and therefore the operation is simple, and the universality is strong.
