Do OBD-II codes differ between vehicle manufacturers?

Yes, while P-codes (powertrain) follow SAE J2012 standards, manufacturers may implement additional parameters or variations. U-codes (network communication) are particularly manufacturer-specific and can have different meanings for different brands.

Should I always check my vehicle's service manual?

Absolutely. Your vehicle's official service manual provides manufacturer-specific interpretations, diagnostic procedures, and repair instructions tailored to your exact model. Generic OBD-II code databases provide general guidance, but factory documentation ensures accurate diagnosis.
