Vehicle warning lights are ambiguous and do not clearly indicate the root cause, leading to misdiagnosis and unexpected breakdowns.

Existing warning light systems are too simplistic and do not differentiate between related faults, causing drivers to chase the wrong problem (e.g., hand brake light confused with brake fluid level).

Implied Software Gaps

An OBD2-powered diagnostic app that interprets warning lights and pinpoints the true fault instead of ambiguous indicators

App Concept

ClearCode Dashboard

A smart OBD2 dongle and companion app that interprets dashboard warning lights and provides plain-English explanations of the root cause along with step-by-step troubleshooting. Instead of a generic 'check engine' light, ClearCode tells you 'Low voltage – alternator failing' or 'Brake fluid sensor fault – check sensor wiring.'

Key Features

Plug-and-play OBD2 dongle with real-time data
App that maps warning lights to specific fault codes and descriptions
Color-coded severity alerts (green/yellow/red) with actionable advice
History log of all warning events and vehicle diagnostics

Target Users: DIY car owners and daily drivers who want to understand their vehicle's warning lights without expensive mechanic visits.

Revenue Model: $49.99 for the dongle + $4.99/mo subscription for advanced diagnostics and history
