A vehicle owner needs a bidirectional scan tool to diagnose a persistent charging system error because basic OBD code readers cannot access real-time powertrain data.

Basic code readers cannot perform bidirectional control or show real-time live data (voltage, draws, PCM parameters) needed to diagnose charging system gremlins.

Mobile bidirectional scan tool app that replaces dedicated hardware and basic code readers

App Concept

AutoDiag Pro

AutoDiag Pro is a mobile app that pairs with a low-cost Bluetooth OBD adapter to provide full bidirectional scan tool capabilities on a smartphone. It shows real-time live data, performs active tests (e.g., command alternator output, injector pulse), and offers guided diagnostics with wiring diagrams. No expensive dedicated hardware needed.

Key Features

Real-time live data graphing for voltage, current, and PCM parameters
Bidirectional control to activate components (alternator, fuel pump, relay tests)
Guided diagnostic workflows with embedded wiring diagrams and TSBs
Wireless Bluetooth OBD-II adapter included or BYO compatible

Target Users: DIY vehicle owners and small independent mechanics who need professional-grade diagnostics without buying a $3k+ scan tool

Revenue Model: $12.99/mo subscription for basic bidirectional features, $24.99/mo for advanced include wiring diagrams and guided diagnostics; adapter sold separately for $49
