0084-10 Vehicle Speed signal rate of change (36)
产生此代码的情况:
ECM 检测到下述情况时：
- 在 3 秒内的连续 8 个读数中，车速信号的变化超过 5 MPH。
- 发动机转速高于预设的 "VSL 保护"减去 100 rpm。
- "VSL Protection"（VSL 保护）被设定为低于 2120 rpm 的值。
注: 如果 ABS 是车速源，ABS 必须不能启动。
系统响应:
在电子维修工具中，"诊断" 将会显示在 "车速"状态的旁边。 检查发动机指示灯点亮。
发动机转速被限制到 "VSL 保护"已经 8 秒。
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
