摘要
一辆奔驰ML320不能起动,通过检测与诊断,发现故障的原因是内置式Immobilizer控制模块N73/1(发动机电子防盗控制系统的主控模块)电路板腐蚀,造成与辅助附件控制模块EAM之间的CAN总线通信数据传输中止,导致发动机控制模块N3/10无法收到起动信号,起动机不能工作,燃油喷射系统被锁止。修复N73/1控制单元电路板后,发动机能起动,故障得以排除。
A BENZ ML320 can not be started. Through inspection and diagnosis, the fault cause has been found that the circuit board of its inner immobilizer control module N73/1 is eroded. After repairing, it can be started again, thus the problem is solved.
