MID 036 - CID 0274 - FMI 13 Atmospheric Pressure calibration required
产生此代码的情况:
存在以下一种情况:
- 新传感器尚未进行压力校准。
- 电子控制模块(ECM)检测到大气压信号小于 45 千帕 (6.5 磅/平方英寸)的绝对压力或大于 111 千帕 (16 磅/平方英寸)的绝对压力。
- 诊断代码 274-03 或 274-04 处于当前状态。
- 大气压的变化幅度大于 5 千帕 (0.7 磅/平方英寸)。
系统响应:
此 CID-FMI 代码处于当前状态时,所有压力校准的公差会默认为 0 千帕 (0 磅/平方英寸)。 该诊断代码处于当前状态。 此诊断代码未记录在存储器中。
测试步骤 1. 进行以下的诊断步骤: 模拟传感器 - 校准
结果:
- 正常 - 停止
- 已修复,正常。 - 停止
