CID 0091 FMI 02
产生此代码的情况:
电子控制模块（ECM）检测到多位置开关的位置组合不正确。
系统响应:
ECM 将会记录此诊断代码。 诊断代码可通过显示模块或电子维修工具查看。
发动机转速默认为低怠速或预定义的安全转速。
诊断代码仍保持激活状态时，发动机将保持该转速。
发动机当前转速确定速度降低量。
检测到故障，而且发动机高于预定义安全转速时，发动机转速将降低至安全转速。
检测到故障，而且发动机低于预定义安全转速时，发动机转速将与安全转速相匹配。
在清除故障之前，ECM 忽略油门开关输入。
在将钥匙开关转至断开位置，然后在返回至接通位置之前，ECM 也会忽略所有的油门开关输入。
发动机将默认为故障缓行回程模式。
测试步骤 1. 进行以下的诊断步骤: 油门开关电路 - 测试
结果:
- 正常 - 停止
