0084-08 Vehicle Speed signal out of range (36)
产生此代码的情况:
发动机控制模块 (ECM) 检测到以下情况:
- "VSL 保护"参数未编程设定在 "TEL" 上。
- 车速高于 204 km/h (127 mph) 至少两秒钟。
注: 除非发动机运转超过三秒钟,否则不会记录该代码。
系统响应:
车速设为 0 km/h (0 mph) ,并且发动机转速限定在编程设定的 "VSL 保护"上。 如果 ECM 提供转速表信号的话,则车辆行驶后发生故障时转速表可反映车速的缺失。 该故障诊断代码为激活状态时,卡特彼勒电子技师 (ET) 状态屏上"车速"旁边会显示"诊断"。 检查发动机指示灯点亮。
驾驶员可能认为发动机功率偏低,并且发动机不能达到期望转速。
测试步骤 1. 进行以下的诊断步骤: 车速和车速表电路 - 测试
结果:
- 正常 - 停止
