Think like a technician. Diagnose like a master. Master Mechanic is an interactive automotive diagnostic simulator built to sharpen the way you approach real-world vehicle problems. Open the repair order, evaluate the customer’s concern, select the right diagnostic tools, gather evidence, identify the root cause, and choose the repair that actually fixes the vehicle. This is more than a multiple-choice quiz. Every case challenges you to follow a logical diagnostic process and prove the fault before making the repair. REALISTIC DIAGNOSTIC CASES Work through 80 repair orders featuring vehicle information, mileage, customer complaints, service-writer notes, test results, verified root causes, and proper repairs. Progress through six skill levels: • Entry Level • Apprentice • Technician • Senior Technician • Master Technician • Diagnostic Specialist USE THE RIGHT TOOL FOR THE JOB Choose from commonly used diagnostic methods and equipment, including: • Scan tool data • Digital multimeter testing • Pressure testing • Smoke-machine testing • Visual inspections • Mechanical-noise inspection • Road testing Run productive tests, eliminate incorrect theories, and avoid wasting time or replacing parts without proof. YOUR DECISIONS MATTER Each repair order scores your performance based on: • Correct root-cause identification • Correct repair selection • Productive diagnostic testing • Diagnostic efficiency • Unnecessary or wasted tests You can identify the correct fault and still choose the wrong repair—just like in a real shop. Detailed results explain the diagnostic logic and provide key takeaways after every case. BUILD YOUR TECHNICIAN CAREER Earn XP, improve your accuracy, build diagnosis streaks, and advance from Lube Tech to Master Technician.
