What is B064F?

DTC B064F is a diagnostic trouble code that indicates a problem with the vehicle's sensor circuit, specifically related to the occupant classification system. This system is designed to assess the weight and position of the passenger seat occupant to determine the appropriate airbag deployment strategy in the event of a collision. If this code appears, it often signifies that the system has detected a fault in the sensor's wiring, the sensor itself, or the control module responsible for processing the data. For many vehicles, especially common models like the 2014-2019 Ford Fusion or the 2016-2020 Chevrolet Malibu, this can lead to a situation where the airbag may not deploy correctly, posing a significant safety risk. Ignoring this code can result in serious consequences during an accident, as the airbags may not function as intended. Therefore, it’s essential to address any issues associated with DTC B064F promptly to ensure safety for all vehicle occupants.

System: B - Body (Airbags, Lighting, Security, Climate Control)

Symptoms

Common symptoms when B064F is present:

  • The airbag warning light remains illuminated on the dashboard, indicating a fault in the airbag system.
  • You may notice that the seat belt reminder chimes or alerts are inconsistent or fail to operate when a passenger is present.
  • In some cases, the passenger airbag may be disabled even when there is a passenger in the seat, which can be a serious safety issue.
  • Difficulty in adjusting the passenger seat or unusual movements may be experienced, suggesting a deeper issue with the seat sensors.
  • A malfunctioning occupant classification system may lead to an unexpected deployment of the airbag, which can cause injury.

Possible Causes

Most common causes of B064F (ordered by frequency):

  1. The most common cause of DTC B064F is a faulty seat occupant sensor, occurring in about 60% of cases. This sensor can wear out over time or be damaged due to excessive weight or improper installation.
  2. Another frequent cause is damaged or corroded wiring in the sensor circuit, which can account for roughly 25% of cases. Inspecting the wiring for wear and tear is crucial.
  3. Improper calibration of the occupant classification system can also trigger this code. Regular maintenance can prevent this issue, especially in vehicles that frequently adjust seating positions.
  4. Less commonly, a malfunctioning airbag control module can cause DTC B064F, representing around 10% of cases. This would require advanced diagnostics to confirm.
  5. In rare instances, an external factor like water intrusion in the seat area leading to sensor failure can also result in this code.
