What will I learn?
You will gain a complete understanding of how modern vehicle systems work and how to diagnose them accurately. The course covers engine performance, electrical circuits, OBD-II fault codes, gearbox faults, brakes, and HVAC systems. You will learn to use professional tools, including scan tools, oscilloscopes, digital multimeters, and smoke machines. Supplementary modules cover hybrid and electric vehicles, ADAS calibration, and cybersecurity awareness. You will also develop a repeatable six-step diagnostic process and learn how to document your findings professionally. Every topic builds towards one goal: accurate, efficient diagnosis without unnecessary parts replacement.
