New vehicles are equipped with more electrical equipment and technology than ever before. This has made vehicle diagnosis more difficult for technicians. Especially in areas previously considered simple, such as charging and starting system diagnostics. The misunderstanding of intricate ECM faults can easily lead a technician in the wrong direction and cause the need for repeat vehicle repairs.
These tips will cover important diagnostic information and common misconceptions around smart charging systems. Unique testing procedures for smart charging systems will be covered to ensure that charging voltages can be read and interpreted correctly. Alternator troubleshooting and diagnostics will also be discussed to help technicians efficiently locate the root cause of the problem.
These technical-focused tips can help reduce diagnostic time and develop effective habits when diagnosing a charging or starting-related problem. These skills are essential for solving difficult starting system faults, including ECM-related issues and no-start concerns. Understanding modern technology gives a technician the knowledge needed for correctly diagnosing an issue on a modern charging or starting system. Following these procedures can ensure that customer vehicles are receiving proper, high-quality starting and charging system diagnostics and repairs.
