Solution for FAW Jiefang P0601 Fault Code?

[OLondon]

After troubleshooting the vehicle, it is often necessary to clear the fault codes. When clearing fault codes, it is essential to follow the specified method for the particular vehicle model. Under no circumstances should the negative terminal of the battery be disconnected haphazardly to clear the fault codes. Otherwise, it may lead to the following two issues: First, it may cause the control center computer of some vehicle models to lose normal records. As we know, certain vehicle models' control computers have an automatic memory function. If the negative terminal's grounding wire is removed carelessly, useful engine operation data stored in the random access memory (RAM) will be erased. This is why some people find that after maintenance and clearing, the vehicle's performance remains subpar for a long time, or previously cleared fault codes reappear after some driving. Second, it may result in the loss of certain functions, such as the audio system's lock feature. In such cases, a complicated repair procedure is required to decrypt the audio system before its original functionality can be restored.
