What is C0B95?

The diagnostic trouble code (DTC) C0B95 indicates a 'Rear Seat Belt Pretensioner Fault.' This code is typically associated with issues in the vehicle's safety systems, specifically the rear seat belt pretensioners, which are designed to tighten the seat belts during a collision. When the onboard diagnostics system detects a fault in this component, it triggers the C0B95 code, illuminating the dashboard warning light. For many drivers, especially those of Ford F-150 models manufactured between 2015 and 2019, encountering this code can be concerning due to the potential implications for passenger safety. Failure to address the C0B95 code could lead to ineffective seat belt operation, increasing the risk of injury during an accident. Symptoms of this code may include a persistent warning light on the dashboard, which can be a nuisance as it may distract from other important vehicle alerts. It’s crucial to understand that while the vehicle may still operate normally, the compromised safety system should not be ignored. Drivers are encouraged to get this checked promptly to maintain the effectiveness of their vehicle's safety features. Addressing the fault not only ensures the safety of passengers but also complies with legal safety regulations, avoiding potential fines or issues with insurance claims in the event of an accident.
