What is B054F?

DTC B054F is a diagnostic trouble code that indicates a potentially serious issue with the vehicle's restraint system, specifically related to the passenger side airbag. This code is primarily seen in various Honda and Acura models, particularly those manufactured between 2015 and 2018. When this code is triggered, it typically signifies that the airbag control module has detected a fault in the passenger side airbag circuit, which could mean a malfunctioning airbag or a problem with the wiring and connectors associated with it. In real-world terms, this means that the airbag might not deploy in the event of a collision, significantly increasing the risk of injury. Owners of affected vehicles should take this code seriously, as it can compromise the safety of all passengers. Ignoring this warning could lead to catastrophic consequences during an accident. Therefore, immediate attention and diagnostic assessment of the issue are highly recommended to ensure that safety systems function correctly.
