name: obd-decoder description: > Decode an OBD-II diagnostic trouble code (DTC) using the CarsXE API. Use this when a user mentions a check engine light code, DTC, or OBD code like P0300, C1234, B0001, or U0100.
When the user mentions an OBD-II code or check engine light code:
- Use the
carsxe_obdtool with the code provided. - Present the decoded fault info clearly: code, description, system affected, possible causes, and suggested fixes.
- Provide context on severity — whether the issue requires immediate attention or can wait.
- If the API key is missing, tell the user to configure it by running
gemini extensions config carsxe.
