What is B0352?

DTC B0352 is a diagnostic trouble code related to the airbag system, specifically indicating a fault in the driver's side airbag circuit. When this code appears, it typically suggests that there is an issue with the wiring, connector, or the airbag module itself. In practical terms, this means that the airbag may not deploy in the event of a collision, which can significantly increase the risk of injury. For vehicle owners, this code is often accompanied by the airbag warning light illuminating on the dashboard. It's important to address this issue promptly, as ignoring it could lead to serious safety hazards. Commonly seen in vehicles like the 2015-2020 Ford Edge and Explorer, the B0352 code can stem from various sources, including faulty connections, damaged wiring, or even a malfunctioning airbag module.
