What is B04CF?

The diagnostic trouble code (DTC) B04CF indicates a fault in the rear passenger side seatbelt latch or its associated system. This code can trigger when the vehicle’s onboard diagnostic system detects that the seatbelt latch is malfunctioning or not communicating properly with the Body Control Module (BCM). This issue is particularly common in Ford Explorer models manufactured between 2016 and 2020, but can also appear in other vehicles with similar seatbelt systems. When this code is present, it often leads to the activation of the seatbelt warning light on the dashboard, indicating a potential safety hazard. In real-world terms, if the seatbelt latch fails to operate correctly, it could compromise the safety of the passenger, as the seatbelt may not engage properly in the event of a collision. Car owners should take this warning seriously, as it not only affects the comfort and confidence of passengers but can also lead to issues during vehicle inspections or potential liability in the event of an accident. Addressing this problem promptly is essential for maintaining vehicle safety standards and ensuring compliance with regulations.
