## What is Master Mechanic Diagnostic Sim?

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. Track your performance across every difficulty level and unlock achievements for great diagnoses—as well as a few memorable mistakes.

DEALER MODE

Choose from five fictional vehicle manufacturers and work through brand-focused repair orders across the complete difficulty ladder. All vehicle brands are fictional, allowing you to practice manufacturer-style diagnostics without representing any official OEM training program.

REPAIR ORDER LIBRARY

Search the complete case library, filter by difficulty, review previous attempts, track your best scores, and replay cases whenever you want to improve your process.

AUTOMOTIVE PRACTICE TESTS

• More than 60 questions in every category
• Randomized 20-question practice tests
• Rotating answer choices
• Immediate feedback
• Detailed explanations

Practice content is independently created and is not affiliated with or endorsed by ASE or any vehicle manufacturer.
