故障现象一辆福特翼虎2.0AT车,行驶里程约为4 300km,因仪表上提示报警信息而进厂检修。故障诊断接车后,试车验证故障,车辆起动后,仪表上显示“低速安全系统感应器阻塞请清理镜头”的报警信息,同时仪表上的黄色警告灯点亮(图1)。经询问驾驶人得知,提车时该故障就曾出现过,当时销售人员给出的解释是设置不当,销售人员重新对车辆进行设置后故障消失,但是此后故障仍会偶尔出现。最近每次起动后仪表上都会出现警告提示信息,由于并不影响车辆的正常行驶,所以才等到车辆首保时顺便对该故障进行报修。
Symptoms A Ford Maverick 2.0AT car, mileage of about 4 300km, due to the alarm information on the instrument into the plant overhaul. Troubleshooting After the car is parked, test the vehicle to verify the fault. After the vehicle is started, the instrument displays the warning message “Low-speed safety sensor jammed to clear the lens.” The yellow warning light on the meter is on (Figure 1). Upon inquiry, the driver was informed that the fault occurred when the vehicle was raised. At that time, the explanation given by the salesman was improperly set. The fault disappears after the salesperson reconfigures the vehicle, but the fault still occurs occasionally. The latest warning message will appear on the instrument after each start, because it does not affect the normal driving of the vehicle, so it will not wait until the first vehicle when the vehicle repair the fault.
