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.

Why might the same code mean different things on different cars?

Vehicle manufacturers can customize OBD-II code implementations based on their specific systems, sensors, and control modules. The same code might trigger different diagnostic procedures or indicate different components depending on the vehicle's make, model, and year.

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.

What are U-codes and how do they differ from P-codes?

U-codes (U0000-U3FFF) are network communication codes that indicate issues with vehicle communication networks like CAN bus, LIN, or other protocols. Unlike P-codes (powertrain), U-codes are highly manufacturer-specific and often require specialized diagnostic tools.
