0084-10 Vehicle Speed signal rate of change (36)
产生此代码的情况:
发动机控制模块 (ECM) 检测到以下情况：
注: 如果 "ABS" 作为车速源使用的话，"ABS" 必须不工作，以使该代码为激活状态。
- 异常速率变化的车速
- 发动机已运转超过 3 秒。
- "VSL 保护"未编程设定在 "TEL" 上。
系统响应:
发动机转速限定在编程设定的 "VSL 保护"上。 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
