故障现象一辆2016款凯迪拉克CT6车,搭载LTG 2.0T涡轮增压发动机,累计行驶里程约为3万km,车主反映,仪表盘上发动机故障灯点亮,并且提示“请速检修车辆”。故障诊断接车后首先试车验证故障现象,故障症状确如客户所述。用故障检测仪检测,发动机控制模块内存储有故障代码U01BO 00,其含义为发动机控制模块与蓄电池电流传感器失去通信。根据故障代码的提示,读取怠速时车身控制模块的电源管理数据,发现蓄电池电流传感器
Failure phenomenon A 2016 Cadillac CT6 car, equipped with LTG 2.0T turbocharged engine, the cumulative mileage of about 30,000 km, the owner reflects the dashboard engine fault light is lit, and prompts “Please speed up the vehicle maintenance” . Fault diagnosis After the first test car to verify the fault phenomenon, the fault symptoms as described by the customer.
