案例1空调只能制冷5min左右故障现象一辆比亚迪S6车,行驶里程约为2000 km,空调制冷约5 min后,空调压缩机会自动停止工作,断开A/C开关后重新接通,空调还是只能制冷约5 min。故障诊断连接空调检测设备,当空调压缩机工作时,空调高压、低压数据均正常,推断故障出在电控部分。连接故障检测仪ED400,进入车身控制模块,发现空调系统中存储了冷暖模式电动机过高的故障信息;记录并清除故障信息后试车,故障依旧。拆下冷暖模式电动机进行检查,未见
Case 1 air conditioning can only be cooled about 5min Symptom One BYD S6 car, mileage is about 2000 km, air conditioning and refrigeration for about 5 min, the air conditioner compressor will automatically stop working, disconnect the A / C switch and reconnect, air conditioning or Only about 5 min cooling. Fault diagnosis Connect air conditioning testing equipment, air-conditioning compressor work, air-conditioning high-pressure, low-pressure data are normal, inferred fault lies in the electronic control part. Connect the fault detector ED400, into the body control module and found the air conditioning system is stored in the cold and warm mode motor fault information too high; record and clear the fault information after the test, the fault still. Remove the heating mode motor to check, no
