P0600 OBD-II：串行通信链路 OBD-II故障代码P0600是什么意思？
OBD-II代码P0600被定义为PCM串行通信链路故障。
See_also: P014C OBD II故障代码 PCM或动力传动控制模块在现代汽车中执行许多重要功能，如管理燃油系统、点火系统、变速器、防抱死制动和牵引力控制系统。 串行通信链路使控制模块能够相互 "对话"。
See_also: P0304 OBDII故障代码 当动力总成计算机中设置代码P0600时，表示动力总成计算机或PCM与一个或多个其他控制模块失去通信。
有此故障代码的车辆应送至修理厂进行诊断。 查找修理厂
P0600 症状
- 发动机检查指示灯点亮
- ABS/牵引力控制指示灯可能点亮
- 透射光可照明
- 车辆可能无法正常行驶和/或换档
- 燃油经济性降低
- 在某些情况下，可能会出现性能问题，如停车时熄火和/或类似失火的症状。
- 在特殊情况下，驾驶员未发现任何不利条件
触发P0600代码的常见问题
- PCM（动力传动控制模块）故障
- PCM数据总线接线/连接有缺陷
- PCM 数据总线接地电路故障
- PCM或其他控制模块控制的输出设备有缺陷
- CAN 总线通信故障
常见误诊
- 根本原因是PCM故障的点火问题
- 根本原因是PCM故障的燃油喷射问题
排放的污染气体
- HCs（碳氢化合物）：未燃烧的原燃料液滴，有异味，影响呼吸，导致烟雾。
- CO（一氧化碳）：部分燃烧的燃料，是一种无味的致命有毒气体。
- NOX（氮氧化物）：在阳光照射下导致烟雾的两种成分之一。
P0600 车间和技术人员诊断理论
PCM与几个不同的系统共享数据输入，如果它们之间的通信链路出现故障，那么一个或多个系统将关闭。 P0600代码的原因可能是数据总线故障、数据总线连接故障或控制模块故障。 如果您必须更换模块，请确保检查所有模块的输出设备和接线是否短路或出现故障。在诊断P0600代码时，重要的是记录任何其他代码和P0600冻结帧数据。 然后，应通过试车重复代码设置条件。 密切注意发动机负荷、节气门位置、转速和路速，因为P0600可能很难检测到。
