故障现象:一辆2009款大众甲壳虫轿车,行驶里程60 000km,客户反映仪表中的ABS、ESP灯常亮。故障诊断与排除:首先用VAS5051B进行诊断,检测到相关故障内容为:00778(转向角传感器);01316(制动系统控制单元)。经查电路得知,S9熔丝(5A)为E256、ASR/ESP按钮、J104制动防抱死系统(ABS)、G85转向角传感器供电。发现S9熔断,更换后故障排除,但是没过几天故障重现,怀疑存在线路短路。经仔细检查没有发现任何可疑之处,所有线束完好无损,于是又再次更换S9熔丝,并观察了很久
Symptoms: a 2009 Volkswagen Beetle sedan, mileage 60 000km, the customer reflects the instrument ABS, ESP lights always bright. Fault diagnosis and troubleshooting: first with the VAS5051B for diagnosis, detection of related failures as follows: 00778 (steering angle sensor); 01316 (brake system control unit). Upon examination of the circuit, the S9 fuse (5A) is powered by the E256, the ASR / ESP button, the J104 ABS, and the G85 steering angle sensor. Found S9 fuse, replacement troubleshooting, but failed to reproduce a few days, there is a suspected short circuit. After careful examination found no suspicious circumstances, all the harnesses intact, so again replace the S9 fuse, and observed for a long time
