0253-02 Check Customer or System Parameters (56)
产生此代码的情况:
这种情况表示需要进行编程的客户指定参数或系统配置参数尚未进行编程。
系统响应:
当对新的发动机控制模块 (ECM) 首次通电时，必须输入下列参数以避免此诊断代码的出现：
- 全负荷设定值 (FLS)
- 全扭矩设定值 (FTS)
- 车速标定
- 额定编号
- 发动机生产序号
- 喷油器调整文件
注: 如果未输入 "额定编号"，ECM 会将发动机功率限制在 119 kW (160 hp)。
- ECM 会将发动机转速限制在低怠速。
测试步骤 1. 进行以下的诊断步骤: ECM 存储器 - 测试
结果:
- 正常 - 停止
