故障现象一辆长安福特福克斯C307 1.8 L自动挡轿车,累计行驶里程约为14.5万km。用户反映,该车出现中控锁失灵,用遥控器无法控制轿车解锁和闭锁,同时仪表盘上的驻车制动指示灯、自动变速器雪地模式指示灯常亮,外界环境温度无显示的故障现象。故障诊断接车后首先验证故障现象,上述故障确实存在。接着连接IDS进行检测,调得的故障代码有:U1900-60-D-DCU、U1900-60-IC、U1900-63-PC M和U1900-P-DCU。根据IDS对这4个故障代码的解释,均为CAN总线故障。根据故障代码的提示,进一步做网络测试,发现与通用电子模
Symptom A Changan Ford Focus C307 1.8 L automatic sedan, the cumulative mileage of about 145,000 km. User reports that the car appeared in the control lock failure, with the remote control can not control the car unlock and lock, while the dashboard parking brake indicator, automatic transmission snow mode indicator light, ambient temperature display no fault phenomenon. Troubleshooting After the car first verify the fault phenomenon, the above fault does exist. Then connect the IDS for detection. The fault codes are: U1900-60-D-DCU, U1900-60-IC, U1900-63-PC M and U1900-P-DCU. According to IDS interpretation of these four fault codes, are CAN bus fault. According to the fault code prompts, to further network testing, and common electronic model found
