What is B0358?

DTC B0358 is a diagnostic trouble code that indicates a fault with the airbag sensor circuit, specifically related to the driver's side airbag. This code can arise due to various reasons, such as a malfunctioning airbag sensor, damaged wiring, or issues with the airbag control module. When this code is triggered, the airbag warning light on your dashboard will likely illuminate, indicating that the airbag system is not functioning correctly. This is a critical safety feature in your vehicle, designed to protect you during a collision, and its failure could result in the airbags not deploying when needed. Commonly found in vehicles such as the 2010-2015 Honda Accord and 2011-2016 Toyota Camry, encountering this issue means you should not ignore it. Not only does it affect your vehicle's safety, but it could also lead to further electrical issues if left unresolved. Therefore, immediate attention is recommended to diagnose and rectify the underlying cause. Additionally, you may experience a decrease in your vehicle's resale value if the airbag system is not functional.
