Map a diagnostic trouble code (DTC) read from an OBD-II scanner to readable diagnosis text. The /obdcodesdecoder endpoint takes the code alone — no VIN or vehicle identity required.

Who uses this API

Repair shops, telematics platforms, and warranty providers call this endpoint to turn a scanner code into plain-language diagnosis text — no VIN required.

Use cases

B2B

• Repair shops — scan-tool intake: Translate a DTC on the work order into a readable diagnosis for the advisor and technician.
• Telematics — in-vehicle alerts: Decode codes reported by a connected device so fleet or warranty dashboards show a cause, not just P0115.
• Warranty — claim context: Attach a human-readable code description when a claim is opened from a diagnostic event.

B2C

• DIY OBD apps: Let a vehicle owner look up a code from a cheap scanner and see what it means.
• Consumer mechanic apps: Show diagnosis text next to a saved vehicle after a scan.
