The Most Common Honda Civic Fault Code List

Almost all cars are controlled by a computer. Whenever the car is in trouble, the computer will immediately remind you, but the computer will use a certain type of code to indicate a Civic problem. Each code indicates a certain abnormal failure in a certain location.

The fault codes used may vary by Honda model. Once the car owner encounters an error, he can query the corresponding Civic fault code in time, and the troubleshooting and handling of the fault problem is recommended to be completed by a professional Honda maintenance engineer. If you want to manually clear the Civic fault code, there are also requirements.

After troubleshooting your car, it is generally necessary to clear the fault codes. When clearing the fault code of the Civic, it should be carried out in strict accordance with the fault code clearing method specified by the specific Honda model, and the negative pole of the battery must not be removed directly in order to clear the fault code.

Otherwise, it is likely to cause the following two problems: First, the control computer of some models will lose the “experience memory”. Many car owners know that the central computer of most models has a memory function, and it is easy to remove the battery.

After the negative ground wire, the useful data of the engine operation stored in the random access memory will be cleared, so that your car will not perform well for a long period of time after maintenance, or it will appear again after driving.

The previous fault code; second, sometimes some useful functions of the Civic are not working, for example, the audio lock function is often lost. In this case, it is very troublesome.
