Engine Operation with Active Diagnostic Codes
如果发动机正常运行时诊断灯点亮，说明系统已经识别到不在规格范围之内的状况。 使用电子维修工具来检查激活的诊断代码。
注: 在故障排除前，功率将受限。 如果机油压力回到正常范围以内，发动机依然可以在额定转速和负载下运行。 但是，应该尽快进行保养。
应查明激活的诊断代码。 应尽快纠正问题的起因。 如果诊断代码激活的起因已被解决且只有此激活诊断代码，诊断灯将熄灭。
发动机的运行和性能可能会因产生的激活的诊断代码而被限制。 加速速率可能会显著放慢。 有关更多激活的诊断代码和发动机性能之间关系的信息，请参阅故障诊断和排除。
