What is B08B6?
DTC B08B6 is a diagnostic trouble code that signifies a problem related to the vehicle's restraint system, specifically indicating a fault in the occupant classification system. This system is designed to ensure that airbags deploy correctly based on the size and position of the occupants in the front seats. When B08B6 is triggered, it generally points to an issue with the sensors that detect the presence and weight of passengers, which can prevent airbags from functioning properly in the event of a collision. This can lead to safety risks, particularly in vehicles like the 2015-2018 Honda Accord or the 2016-2019 Ford Edge, where passenger safety is paramount. If you ignore this code, you may notice that the airbag warning light remains illuminated on the dashboard. This could mean that in a crash, the airbags may not deploy as needed, significantly increasing the risk of injury. Therefore, it’s vital to address this issue promptly to ensure the safety of all vehicle occupants.
