高档轿车保有量正大幅度增加,各种先进的仪器及检测诊断设备层出不穷,采用仪器诊断已成为故障诊断的重要手段。但是,仪器诊断也有其缺陷,如成本高、对操作人员的文化水平要求高、对某些故障(如线路故障)的诊断效率低,以致于造成误判,给车辆故障诊断带来了困难。因此,充分利用成熟的维修经验,与传统的诊断方法——“问”、“看”、“听”、“闻”、“试”、“摸”相辅相成提高维修效率是汽车维修中不可缺少的组成部分。
High-end car ownership is significantly increased, all kinds of advanced equipment and testing equipment after another, the use of diagnostic equipment has become an important means of fault diagnosis. However, the diagnosis of instruments also has its drawbacks, such as high cost, high requirement on the cultural level of operators, low efficiency of diagnosing some faults (such as line faults), resulting in miscarriage of justice and causing difficulties in vehicle fault diagnosis. Therefore, make full use of mature maintenance experience, with the traditional diagnostic methods - “ask ”, “look ”, “listen ”, “smell ”, “try ”Complementarity to improve maintenance efficiency is an integral part of vehicle maintenance.
