商用汽车启动系统控制电路故障诊断与排除

Fault Diagnosis and Elimination of Control Circuit of Commercial Vehicle Starting System

当前,随着汽车电子技术的不断革新,汽车启动系统的电气化已经非常普遍。在日常使用中,若启动系统控制电路出现故障,就会影响启动系统正常工作,进而使得发动机无法正常启动,导致汽车无法正常驾驶。本文以市面上保有量较大的某型载货汽车为例对商用汽车的启动控制电路进行故障分析和排查。

At present,with the continuous innovation of automobile electronic technology,the electrification of automobile starting system has become very common.In daily use,if the control circuit of the starting system fails,the normal operation of the starting system will be affected,and the engine cannot be started normally,causing the car to fail to drive normally.This article takes a certain type of truck with a large amount on the market as an example to analyze and troubleshoot the startup control circuit of a commercial vehicle.
