| 摘要： | Diagnosis is a series of logical steps to ascertain the cause of a failure or issue. The first step of any diagnostic routine is to verify the issue. Because how can you fix or repair something you cannot experience or see?The next step in the process is to compare the vehicle's insufficient functionality to how the system is supposed to work. Is the concern a normal operating characteristic or an actual problem that requires more attention? Understanding how a specific part functions when operational, helps guide technicians to the source of the malfunction when challenges arise.In addition to knowing how the system works, it is important to look up information on how it is known to fail. Technical Service Bulletins (TSBs), special service messages and additional resources are provided by many original equipment manufacturers to save time and diagnose known issues. |
