About
OBD Vault connects your smartphone to any standard ELM327 Bluetooth Low Energy (BLE) adapter, turning raw automotive diagnostics into clear, actionable answers.
Whether you are a professional technician troubleshooting an engine issue or a first-time car owner seeing a Check Engine light on the dashboard, OBD Vault provides immediate, unfiltered access to vehicle data.
FOR DRIVERS: PLAIN-LANGUAGE DIAGNOSTICS
When a warning light appears, you do not need to decipher cryptic codes or worry about being overcharged at a service center:
- Clear explanations: Understand what each fault code means without searching through technical forums.
- Safety assessment: Know immediately whether a detected fault allows you to drive safely home or requires an immediate stop.
- AI-assisted analysis: Connect your telemetry directly to your AI like ChatGPT and Claude via Model Context Protocol (MCP) to ask about symptoms, likely causes, and estimated repair steps.
- Pre-purchase inspection: Scan a used car before buying to detect hidden faults or recently wiped error codes.
FOR MECHANICS AND ENTHUSIASTS: UNFILTERED TELEMETRY
OBD Vault delivers standard SAE/ISO diagnostic parameters directly from the Engine Control Unit (ECU):
- Complete DTC management: Read confirmed, pending, and permanent trouble codes across powertrain and emissions systems. Clear codes with explicit ECU confirmation.
- High-frequency live sensors: Track engine coolant temperature, engine RPM, vehicle speed, mass air flow (MAF), intake manifold pressure (MAP), throttle position, and calculated load.
- Low-latency BLE communication: Optimized command polling with automatic reconnect and strict data-quality tracking.
- Native MCP Server support: Expose vehicle telemetry directly to external AI workflows and automated diagnostic scripts.
- Multi-brand validation: Compatible with major vehicle platforms including Volkswagen Group (VAG), Stellantis (Citroën, Peugeot, Opel), BMW, Toyota, Ford, Renault, and other OBD-II compliant vehicles.
