Dyno Mode
测功机模式是软件的一个功能，有助于确保测功机运行的精确。 无论何时，只要是在发动机上进行测功机运行都应使用测功机模式。 该模式会停用某些会造成测功机运行错误的策略。 例如，冷却风扇可能会停用。 测功机模式会停用下列特性：
- 怠速停机
- 冷却风扇控制
- 燃油温度功率修正
- 来自防抱死制动系统 (ABS) 和牵引力控制系统的指令
- 某些减额
测功机模式可以在测功机运行之前利用卡特彼勒电子技师 (ET) 启动。 发动机控制模块 (ECM) 带有一个内部计时器，允许测功机模式启动 30 分钟。 30 分钟后，测功机模式必须重新开始。 下列事件会使测功机模式退出：
- 循环操作钥匙开关。
- ECM 失去与卡特彼勒 ET 的通信。
