Abstract
This paper focuses on the Shanghai-GM Buick steering system components, functions, principles and common fault diagnosis and troubleshooting. According to steering system structure and work principle analysis to heavy, low head, straight driving automatic running deviation and unilateral under steer when common failures diagnosis and elimination, which focus on analysis turned heavy in several different situations. Also puts forward to repair the faults that appear feasible methods, analysis of each question has specific and good knowledge of the course seriously summed, to further understand Buick steering system of knowledge, systematic analysis of the failure causes and to obtain good diagnostic program and thus excluded.
