Troubleshooting. Introduction

This section proposes the simplest scheme for finding out the causes of malfunctions and failures occurring in the components and systems of the vehicle. Failures and their possible causes are grouped according to their relation to certain components or systems of the vehicle, such as engine, cooling system, etc., in addition, the text provides links to chapters and sections related to these problems.

Remember that successfully completing a root cause troubleshooting is not black magic reserved for experienced professional mechanics, but is determined by a combination of specific knowledge and a patient, systematic approach to investigating the problem. You should always move from simple to complex, bring each check to its logical conclusion and try not to miss the obvious facts - anyone can forget to fill the fuel tank or leave the lights on at night.

Finally, you should always try to get a clear picture of the development of the malfunction and take appropriate steps to prevent recurrence. If the failure of the electrical equipment occurred due to a violation of the quality of the contact, check at the same time the condition of all other contacts and electrical connectors of the system. If the same fuse continues to blow several times in a row, there is no point in replacing it further - you must try to find out the cause of the failure. Remember that the failure of a minor component may be a sign of a malfunction of a more important node or the entire system.
