General information about troubleshooting (Mazda Capella GF)

This section is a quick guide to troubleshooting the most common problems with vehicle systems. These faults are grouped under headings that relate to specific components and systems. They also contain a link to a chapter that describes the issue in more detail.

Remember that troubleshooting is not some kind of black magic that only experienced mechanics can do. It is simply the result of knowledge of the device combined with intelligent and systematic study of the problem. Work consistently, start with the simplest solution and gradually move on to more complex ones. Don't miss the obvious. If there is no fuel in the tank, the engine will not start, and if you leave the car overnight with the headlights on, the battery will die. Don't look for deeper reasons. No one is immune from such mistakes, and neither are you.

Finally, if you have found the cause of the problem, consider why it might have happened and what can be done to prevent it from happening again. If the failure of any electrical equipment is due to poor contact, check the contacts of other electrical circuits to ensure that they do not cause the same malfunction. If the same fuse blows repeatedly, do not replace it. until the cause was found and eliminated. Remember that a minor failure may be a harbinger of a more serious problem.
