When AI Wins

1. Data Analysis

Why AI Wins:

• Analyzes OBD2 fault codes and live data
• Processes thousands of data points
• ⏳ Advanced diagnostics (40+ modules) - coming 2026
• Identifies patterns humans miss
• No fatigue or distraction

Example:

• Vehicle: 2018 Honda Accord
• Problem: Intermittent misfire (only happens occasionally)
• Mechanic: "No codes, can't reproduce, seems fine"
• SKANYX AI: Detected misfire pattern in historical data, identified cylinder 3
• Result: AI caught it, mechanic missed it

2. Pattern Recognition

Why AI Wins:

• Compares to millions of vehicles
• Identifies degradation trends
• Predicts failures before symptoms
• Sees patterns over time

Example:

• Vehicle: 2015 Ford F-150
• Problem: Battery voltage declining (not yet failed)
• Mechanic: "Battery tests fine, no problem"
• SKANYX AI: Detected declining pattern, predicted failure in 3 weeks
• Result: AI predicted it, mechanic couldn't see it yet

3. Comprehensive Scanning

Why AI Wins:

• Scans OBD2 systems and monitors live data
• Comprehensive analysis
• ⏳ Advanced diagnostics (40+ modules) - coming 2026

• Mechanic: Visually inspected, caught worn pads
• Result: Mechanic caught it, AI can't see physical wear

2. Test Drives

Why Mechanics Win:

• Can drive and feel problems
• Hear unusual sounds
• Feel vibrations
• Experience symptoms

Example:

• Vehicle: 2016 Mercedes C-Class
• Problem: Transmission shift quality (subtle, no codes)
• SKANYX AI: No codes, transmission data normal
• Mechanic: Test drive revealed rough shifting
• Result: Mechanic felt it, AI couldn't detect subtle feel

3. Complex Diagnoses

Why Mechanics Win:

• Experience with similar problems
• Can combine multiple clues
• Understands vehicle history
• Intuition and judgment

Example:

• Vehicle: 2014 Audi A4
• Problem: Multiple related issues (vacuum leak causing other problems)
• SKANYX AI: Detected symptoms, not root cause
• Mechanic: Connected dots, found root cause
• Result: Mechanic diagnosed root cause, AI saw symptoms

4. Non-Computer Problems

Why Mechanics Win:

• Problems not in computer systems
• Mechanical wear
• Physical damage
• Non-electronic issues

Example:

• Vehicle: 2011 Ford Focus
• Problem: Worn suspension bushings (no codes)
• SKANYX AI: No codes, suspension not fully monitored
• Mechanic: Physical inspection found worn bushings
• Result: Mechanic caught it, AI can't detect physical wear
