故障现象一辆福特新福克斯车,搭载1.6 L发动机和自动变速器,行驶里程约为3.8万km。据驾驶人反映,有时接通点火开关尝试起动车辆时,发动机无反应,起动机也不转动;断开点火开关重新起动发动机,发动机又能正常起动着机了。故障诊断接车后试车验证故障,维修人员反复起动车辆,故障并未出现。连接IDS调取故障代码,无故障代码存储。再次尝试重新起动车辆,故障终于出现了。当点火开关位于起动挡时,起动机不转动。由于该故障为偶发故障,且毫无规律可言,这给故障排查带来很大难度。

According to the driver reflected, sometimes turn on the ignition switch to start the vehicle, the engine does not respond, the starter does not rotate; disconnect the ignition switch to restart the engine, the engine can start the machine again. Fault diagnosis After the test car to verify the fault, maintenance personnel repeatedly start the vehicle, the fault did not appear. Connection IDS recall fault code, fault-free code storage. Try again to restart the vehicle, the fault finally appeared. When the ignition switch is in the start gear, the starter does not rotate. As the fault is an accidental failure, and there is no law at all, which brings great difficulty to troubleshoot.
