自动变速箱维修中里程表维护情况

发布日期: 2020-06-11 来源: http://www.jnbsx.com/ 点击:

  在我们的日常生活中,汽车都是要进行保养和测试的,那么在平时的保养或维修中汽车的里程表出了问题该如何处理呢?今天我们来听济南自动变速箱维修公司为大家介绍一下这方面的原因:

  In our daily life, the car is to be maintained and tested, so how to deal with the problem of the odometer in the normal maintenance or repair? Today, let's listen to Jinan automatic transmission maintenance company to introduce the reasons for this:
  一、故障原因分析:
  1、 Failure cause analysis:
  可能是里程表指针和液晶计数系统不工作,但发动机正常,换挡正常。当仪器组件连接线拆下未拔下时,返回找到速度信号终端,用模拟信号发生器驱动,指针显示里程,计数器工作。安装旧仪器进行测试是正常的。初步判断仪表总成无故障。故障应在速度传感器或信号线上。接下来,寻找速度传感器。查阅数据,这个传感器应该是三线霍尔速度传感器,但我没有看到这个传感器在引擎室。在这一点上,我很困惑。由于该车配备了CAN总线系统,所以我不知道速度信号是针对ABS系统,自动传动系统还是发动机系统。

  It may be that the odometer pointer and LCD counting system are not working, but the engine is normal and the shift is normal. When the connecting line of the instrument component is removed and not unplugged, return to find the speed signal terminal, drive it with the analog signal generator, display the mileage with the pointer, and the counter works. It is normal to install old instruments for testing. Preliminarily judge whether the instrument assembly has any fault. The fault should be on the speed sensor or signal line. Next, look for the speed sensor. Looking up the data, this sensor should be a three-wire Hall speed sensor, but I didn't see this sensor in the engine room. At this point, I am confused. Since the car is equipped with CAN bus system, I don't know whether the speed signal is for ABS system, automatic transmission system or engine system.
  2检查步骤(维护过程):
  2 inspection steps (maintenance process):
  从仪表盘上沿检测到的速度信号线,到线束直接连接到发动机的电脑号上。9头。发动机的计算机出问题了吗?再次检查发动机计算机终端9的速度输出信号线。该电路被发现进入仪表板,驾驶侧多通道传输装置,巡航系统和防抱死系统。依次尝试断开设备中的速度信号线。发现巡航系统蓝白线断开时,仪表盘速度指示器显示正常。到目前为止,故障点已经在巡航计算机上找到。巡航计算机的损坏直接影响速度信号的输出。这时司机想起汽车的巡航系统不工作了,没有修好。因此,断开巡航计算机的蓝线和白线,从发动机计算机的输出速度信号线。重新安装车辆,恢复旧的组合仪表。
  From the speed signal line detected on the instrument cluster, connect the harness directly to the computer number of the engine. 9 heads. Is there something wrong with the engine computer? Check the speed output signal line of engine computer terminal 9 again. The circuit was found to enter the instrument panel, the driver side multichannel transmission, the cruise system and the anti lock system. In turn, try to disconnect the speed signal line in the device. It is found that when the blue white line of the cruise system is disconnected, the instrument cluster speed indicator shows normal. So far, the fault point has been found on the cruise computer. The damage of cruise computer directly affects the output of speed signal. At this time, the driver remembered that the cruise system of the car was not working and had not been repaired. Therefore, disconnect the blue line and the white line of the cruise computer, and output the speed signal line from the engine computer. Refit the vehicle and restore the old instrument cluster.
