SRS气囊系统 摘要 Inspection and diagnosis about SRS system Abstract In recent years, as the reduction of production costs of the SRS airbags, they have now been widely used. When facing a serious vehicle collision accident, SRS System synergy of three-point seat belts provides effective protection for front members in the head and chest. When side collision occurs, side SRS reduce the extent of the injury at the regional parts of passengers. This paper presents a safety airbag domestic and foreign development application, composition, working principle and mechanism of the protective effect, also briefly introduce characteristics, composition and mechanisms of Japanese Mazda 626 and Honda Accord series SRS system, It focused on detection and diagnosis respectively. With the knowledge we learned, a lot of collected information, and the corresponding fault diagnosis map made for specific models respectively, two specific types of fault diagnosis, According to the diagnostic process and, based on its own understanding of the additional diagnostic flow charts, which also belongs to this paper innovations. Finally, it analyzes fault diagnosis of the specific application through fault case. Key words：SRS；Fault；；Diagnosis 目录 摘 要 I Abstract II 1 绪 论 1 1.1 SRS气囊系统的发明 1 1.2 SRS安全气囊系统的发展及应用现状 1 1.2.1 SRS安全气囊系统的发展情况 1 1.2.2 发展趋势 2 1.2.3 课题选题的意义 3 2 安全气囊系统的基本知识 4 2.1 安全气囊的分类 4 2.2 安全气囊的组成 4 2.3 安全气囊的原理 5 2.4 碰撞传感器 6 2.5 SRS电脑、SRS指示灯和SRS气囊组件 6 3 马自达轿车SRS气囊系统的检修 7 3.1 马自达轿车SRS气囊系统的概述 7 3.2 马自达SRS系统的组成和工作原理 7 3.3 SRS安全气囊控制系统的结构 8 3.4 SRS安全气囊控制系统检测与诊断 9 3.4.1 故障诊断步骤 9 3.4.2 SRS安全气囊控制系统故障的诊断 13 3.5 安全气囊控制系统间歇性诊断 22 4 本田雅阁安全气囊检测维修 23 4.1 结构特点 23 4.2 SRS系统故障自诊断测试 23 4.3 SRS的故障检测与诊断 26 4.3.1 SRS指示灯不亮 26 4.3.2 SRS指示灯不熄灭 27 4.3.3 无故障码自诊断后灯亮 28 4.3.4 DTC1-1和DTCl-2 29 4.3.5 DTC1-3 31 4.3.6 DTC 1-4 31 4.3.7 DTCl-5 33 4.4 清除故障码存储 34 5 SRS故障典型维修案例分析 35 5.1 故障实例1 35 5.2 故障实例2 35 5.3 故障实例3 36 5.4 故障实例4 37 结 论 38 致 谢 39 参考文献 40 附 录 A 40 附 录 B 41 附 录 C 42 附 录 D 43 1绪 论 系统的发明 SRS气囊系统是美国机械工程师约
