P0632 code definition

The P0632 trouble code detects that the PCM is unable to read the odometer.

P0632代码意味着什么

The P0632 code is a generic, but fairly uncommon OBD-II trouble code that signals an odometer issue. In the case of the P0632 code, the powertrain control module (PCM) is unable to recognize the reading from the odometer.

What causes the P0632 code?

The P0632 trouble code is almost always caused by a PCM that needs reprogramming. This can occur because:

• 更换或修理PCM而未重新编程
• 车辆中的电池被排出
• 电线，连接器和保险丝等电气组件受损
• Defective PCM.
  

What are the symptoms of the P0632 code?

A vehicle with the P0632 trouble code will usually have an illuminated Check Engine Light on the gauge cluster. In most cases, the vehicle will be incapable of starting.

机械师如何诊断P0632代码？

P0632代码将使用标准的OBD-II故障代码扫描仪进行诊断。经过认证的技术人员可以使用扫描仪的冻结框架数据评估代码，还可以检查存在的任何其他故障代码。如果机械师记录了多个故障代码，则需要按照显示的顺序解决它们。然后，机械师应重置故障代码，重新启动车辆，并测试以查看P0632代码是否保留。如果代码不保留，则可能是间歇性错误或不准确的触发器。

If the P0632 trouble code remains, then the mechanic will visually inspect the electrical system, and replace any blown fuses, loose or corroded connectors, or short or open wires. Next, the mechanic will need to find out the history of the PCM, to know if it requires programming. If the PCM was recently replaced or repaired, then a reprogram will almost surely fix the issue. If not, the mechanic should ask the vehicle’s owner if the battery has died recently; if it has, then a reprogram is in order. If none of these things have occurred, then the PCM will need to be replaced.

替换或重新编程任何组件后，机械师应再次重置故障代码，重新启动车辆，并检查是否仍然存在P0632代码。这有助于技术人员一旦解决，就可以知道。

诊断P0632代码时常见错误

诊断此代码时最常见的错误是未能遵循OBD-II故障代码协议。对于机械师而言，始终以分步订单遵守协议万博亚洲客户端，避免进行错误的维修并确保有效检查很重要。

Often PCMs are replaced without first checking to see if they merely require reprogramming.

How serious is the P0632 code?

In most cases, a vehicle with the P0632 will refuse to turn on, so the car should be inspected as soon as possible.

哪些维修可以修复P0632代码？

P0632故障代码的维修是：

• 重新编程PCM
• Replacement of the electrical components
• 更换PCM
