摘要
通过丰田克雷西达(Cressida)自动空调因功率晶体管的基极导线与集电极反馈导线接反,而导致Ⅰ、Ⅱ档风速与Lo档相同、Hi档正常的故障,详细分析了该车风机的控制原理、信号传输过程;叙述了发现该故障的思路,以及电压、电流变化的原理。
Based on the faults caused by the wrong connection of the base lead and the collector feedback lead of the air conditioner power transistor on TOYOTA CRESSIDA, the control principle and signal transmission process of its fan are analysed in details. The way to find the faults and the principles of voltage and current changes are also told here.
