凯美瑞双擎混合动力无法驱动故障分析

Fault Analysis on Unsuccessful Drive of CAMRY HV

随着新能源混合动力汽车的普及,汽车的新型故障频出。如果不及时分析故障产生的原因和相应的维修技术,将会影响新能源汽车的良好运行。以凯美瑞双擎混合动力无法驱动故障为例,借助于某专用“Techstream”诊断控制系统读取DTC故障码,提出采用兆欧表“分段”检修的方法,解决了因零部件绝缘电阻减小造成短路的问题。

With the popularity of new energy hybrid electric vehicles,new types of vehicle failures occur frequently.If the failure causes and corresponding maintenance technology are not analyzed in time,the good operation of new energy vehicles will be affected.Taking the failure of Camry dual engine hybrid power as an example,with the help of a special"Techstream"diagnostic control system to read the DTC fault code,the method of"subsection"maintenance of megohmmeter was proposed to solve the problem of short circuit caused by the reduction of insulation resistance of parts.
