The seven troubleshooting steps provide a systematic approach to solving vehicle problems. First, identify the problem by gathering information about symptoms and when they occur. Second, research possible causes using manuals, forums, or diagnostic codes. Third, develop a theory about the most likely cause based on your research. Fourth, test your theory by inspecting or testing the suspected component. Fifth, implement the fix by repairing or replacing the faulty part. Sixth, verify the repair worked by testing the vehicle under the same conditions that caused the original problem. Seventh, document what you found and fixed for future reference.
