The Automotive Electrical/Electronics (Auto 170) course is a cornerstone of modern automotive technician training. It transforms students from beginners into proficient diagnosticians of a vehicle’s most complex systems. This exam validates your understanding of how electricity powers everything from headlights to advanced engine control modules. It is designed for aspiring automotive service technicians, students currently enrolled in technical programs, or current mechanics looking to formalize their electrical skills.
This course moves systematically from fundamental principles to applied diagnostics on real vehicles. You will cover essential topics such as basic electrical theory, including Ohm’s Law, voltage, current, and resistance. The curriculum includes in-depth studies of circuit design, troubleshooting with multimeters and oscilloscopes, and interpreting intricate wiring diagrams. Students master the diagnosis and repair of battery systems, starting motors, charging circuits, and lighting systems. Advanced topics may cover vehicle networking systems (CAN Bus) and basic semi-conductor electronics.
The final exam for Auto 170 is designed to test both theoretical knowledge and practical logical reasoning. While specific school formats may vary slightly, you can typically expect a comprehensive set of multiple-choice questions focusing on theory, component function, and diagnostic logic. Many programs also include a mandatory hands-on practical component where you must diagnose a structured "bug" in a real vehicle's wiring system within a set time limit. The written portion usually takes between 60 to 90 minutes. A passing score generally rests around 70% to 75% scaled scoring.
Effective study begins with mastering theoretical concepts before applying them hands-on. Review your textbook and class notes thoroughly, paying special attention to wiring schematics. Take multiple practice exams to simulate test conditions and identify weak knowledge areas. Spend ample time in the lab practicing with a digital multimeter (DMM) on various circuit configurations. Since Auto 170 is typically a specific college course, the final exam is administered on-campus at your authorized technical school or community college testing center. Consult your course syllabus or instructor for specific scheduling and location details.
Completing Auto 170 opens doors to various entry-level and specialized roles within the automotive industry. It is a required step toward becoming an ASE Certified Technician in Electrical/Electronic Systems (A6). Career paths unlocked by this training include: Entry-Level Automotive Technician General Service Mechanic Specialized Automotive Electrical Technician Mobile Electronics Installer (Aftermarket systems) Shop Foreman (With further experience) Automotive Parts Specialist
