What does fault code B0003 mean?

The B0003 fault code, applicable to all car manufacturers, means “Driver Frontal Stage 3 Deployment Control (Subfault)“.

Background Information: Newer cars use multi-stage airbags to regulate the pressure within the airbags. The higher the pressure, the stronger the airbag deployment. The system automatically determines the airbag deployment strength based on parameters such as collision intensity, passenger weight, whether seat belts are worn, child seats are in use, and distance from the airbag. This design ensures that the airbags deploy with moderate intensity in most collisions, reserving maximum intensity for the most severe impacts.

Tip: To quickly find the B0003 fault code, you can use a professional airbag scanner tool. This will help you accurately locate the problem.
