Automotive RepairDiagnostics & Troubleshooting4HighCar Owner$ implied
Car stuck in limp mode with persistent electrical fault codes after alternator replacement, unable to diagnose root cause between ECU failure and wiring harness issue.
Existing diagnostic tools only read codes but cannot pinpoint whether the root cause is ECU failure, connector corrosion, or grounding issue without expensive ECU replacement or specialized wiring diagrams.

Implied Software Gaps
- Guided diagnostic workflow that validates wiring integrity and ECU health based on fault patterns
App Concept
SmartDiag Pro
SmartDiag Pro is an AI-powered diagnostic assistant that combines OBD-II scanning with guided electrical testing workflows. It walks users through step-by-step grounding/pin corrosion checks using wire diagrams and live voltage maps, then suggests the most likely fix before costly ECU swaps.
Key Features
- Interactive wiring diagrams overlaid with fault code correlations
- Guided multimeter testing for ground points and harness connectors
- Automated voltage log analysis to detect dropouts from alternator failure
- ECU health check by monitoring sensor rail consistency
Target Users: DIY car enthusiasts and independent mechanics working on modern VW/Audi/BMW vehicles with complex electrical systems.
Revenue Model: Freemium with basic code reading; $9.99 per diagnosis report or $19.99/mo subscription for unlimited guided diagnostics and wiring diagrams.
