When the vehicle electrical system fault, should the vehicle electrical system for detection, diagnosis and repair, in the detection, diagnosis and repair process requires repair technician on the vehicle electrical system has a solid theoretical foundation and strong practical skills, but also have the suitable diagnostic method. So, after a failure occurs, appropriate diagnostic methods for successful troubleshooting key. Master auto circuit fault diagnosis methods and steps, the exclusion of automobile electrical fault becomes simple and orderly. In addition, in todays society, which requires repair personnel to constantly update knowledge, self learning, to keep up with the development of science and technology, can successfully solve the fault. This paper first introduces the mass of the car electrical system general diagnostic method and fault diagnosis, and then to the Volkswagen Santana cars as an example, mainly introduce the ABS, ignition system fault diagnosis and troubleshooting.
