Course Overview

The Certificate in Automotive Vehicle Diagnostics & Fault Finding is designed to provide learners with practical knowledge and technical skills required to inspect, diagnose, troubleshoot, and identify faults across modern automotive mechanical, electrical, and electronic systems. The program covers systematic diagnostic methods, diagnostic scan tools, fault codes, live data, sensors, actuators, engine management, fuel and ignition systems, starting and charging systems, braking, steering, suspension, transmission, and vehicle communication systems.

Learners will develop the ability to approach vehicle faults systematically, collect diagnostic information, identify symptoms, perform appropriate tests, interpret results, and determine possible causes before recommending corrective action. The program emphasizes practical fault-finding techniques, diagnostic equipment, electrical testing, electronic system analysis, preventive maintenance, and professional documentation.
