You need to start by reading the repair order to identify the exact problem (such as does not crank or cranks, but does not start). Next, you should check any service information regarding the electrical, electronic, ignition, and fuel systems of the vehicle. You must not only read complex technical information related to servicing the vehicle, but you must also comprehend the information. To do this, you must be familiar with basic scientific and mathematical principles, such as heat transfer, ratios, and chemi- cal reactions, as well as the actual operation of automotive systems. On a modern vehicle, guessing will not work as a form of diagnosis. Successful technicians must also think logically and critically. This means that you must rationally evaluate and solve problems that arise during vehicle troubleshooting and repair. Recall the repair order for the no-start vehicle just mentioned. You must use logi- cal troubleshooting principles to determine the actual problem by checking the battery condition, fuel supply, spark condition, engine compression and timing, and other possible causes of the issue. Solving the puzzle may involve obtaining specifications, studying sche- matics, and using test equipment and diagnostic software, Figure 1-16. At this point in the repair process, the ability to employ a logical thought progression is invaluable. You systematically determine what is not causing the vehicle problem until you come to the actual cause. Once you have determined the cause of the problem, you must record it in an understandable way so that the service writer or shop foreman can call the vehicle owner for permission to repair the vehicle. Since writing repair estimates and other documents is required on a daily basis, you must be able to write in a clear and direct way. Be sure your writing is legible and expresses your entire meaning in a concise manner. Assuming permission is given, you proceed to repair the vehicle using the correct methods as given in the ser- vice information. You have to read and make sure that you comprehend the information to ensure that no parts are broken or unnecessarily removed. After replacing defective parts, you reassemble according to the service information. Again, your reading and writing ability, ability to think logically and analyze critically, and your understanding and application of basic math and sci- ence principles will result in a successful repair. Be a Team Player Make every effort to get along with your supervisors and fellow employees, Figure 1-17. When it is necessary to communicate information, do so clearly, both verbally and in writing. If you are unable to complete a job with- out help, request assistance. Assist other workers on jobs when they need help, if possible. Share repair ideas and thoughts if you or a coworker encounter a difficult or complex vehicle repair. Sometimes a second set of eyes looking at a repair can provide a fresh perspective and lead to a successfully completed job. Avoid Confl icts Conflicts and differences of opinion occur between human beings. You, however, should do your best to avoid starting or escalating conflicts, especially in the shop when customers kurhan/Shutterstock.com Figure 1-16. Thinking critically about a vehicle problem and using the proper diagnostic test equipment to systematically eliminate possible causes are invaluable skills for an auto technician.
