What is B0480?

DTC B0480 is a diagnostic trouble code that indicates an issue with the driver's airbag circuit, specifically related to the airbag module. This code is particularly prevalent in vehicles such as the 2015-2020 Ford F-150 and other models equipped with advanced airbag systems. When this code is triggered, it means that the vehicle's onboard diagnostics have detected a malfunction in the driver's airbag system that can prevent it from deploying in the event of a collision. This could be due to issues such as a faulty airbag module, damaged wiring, or poor connections within the airbag circuit. Real-world implications of this code are significant; driving a vehicle with B0480 can compromise your safety and that of your passengers, as the airbag may not function properly during an accident. This code often leads to the illumination of the airbag warning light on the dashboard, prompting the need for immediate attention. If left unresolved, it can result in costly repairs and potential safety risks. Therefore, addressing DTC B0480 promptly is critical for maintaining vehicle safety.
