一辆上海通用别克车,其ANTI LOCK指示灯开始偶尔亮,而后逐渐频繁地亮,最后常亮。调取的故障代码为C1232,表示左前轮速传感器电路断路或短路。在清除故障代码后ANTI LOCK指示灯依然常亮。再次调取的故障代码仍为C1232。先关闭点火开关,拆下左前车轮和拔下左前轮速传感器导线侧连接器,然后测量左前轮速传感器侧连接器两端子间的电阻,为∞(应为850～1350Ω)。测量结果表明该轮速传感器电路有断路处。上海通用别克车的轮速传感 A Shanghai GM Buick, the ANTI LOCK indicator light began to occasionally bright, and then gradually frequent light, the last light. The fault code retrieved is C1232, indicating that the left front wheel speed sensor circuit is open or shorted. The ANTI LOCK indicator remains solid after clearing the error code. Recall the fault code is still C1232. First turn off the ignition switch, remove the left front wheel and unplug the left front wheel speed sensor wire connector, and then measure the left front wheel speed sensor connector resistance between the two terminals, ∞ (should be 850 ~ 1350Ω). The measurement results show that the wheel speed sensor circuit has an open circuit. Shanghai GM Buick car wheel speed sensor
