系统电压示意图 | |
控制装置检测到触针 1 上的电气系统电压高于正常范围（高于 29.5 伏持续两秒钟）后会记录该诊断代码。
该诊断代码可能的原因如下：
- 充电系统部件出故障。
- 控制装置存在故障。 这不太可能。
注: 检查 15 A 保险丝，确保它没有分离。
测试步骤 1. 检查有无激活的诊断代码。
- 将断路开关和钥匙起动开关转到接通位置。
- 查看该诊断代码的状态。
预期结果:
诊断代码为非激活状态。
结果:
- 是 - 诊断代码为非激活状态。 转至测试步骤 2。
- 否 - 诊断代码处于激活状态。
修复: 控制装置存在故障。 请参阅故障诊断和排除, "ECM（Electronic Control Module，电子控制模块）- 更换"。
停止
测试步骤 2. 检查充电系统。
- 起动发动机。
- 以高怠速运转发动机。
- 查看该诊断代码的状态。
预期结果:
诊断代码为非激活状态。
结果:
- 是 - 诊断代码为非激活状态。 观察是否重新出现。停止
- 否 - 诊断代码处于激活状态。
修复: 充电系统当前的充电电压过高。 检查充电系统。 请参考专门说明书, REHS0354, "充电系统故障诊断与排除"。
停止
