How can I prevent B016B from happening again?

Regularly inspect your seat belt system for wear and tear, ensure that connectors are clean and dry, and avoid using aftermarket parts that may not meet OEM standards.

What is B016B?

The Diagnostic Trouble Code (DTC) B016B indicates a malfunction related to the seat belt sensor system in vehicles such as the 2015-2020 Ford F-150 and similar models. This code is triggered when the Vehicle Control Module (VCM) detects an open or short circuit in the seat belt tension sensor circuit. The seat belt system is critical for passenger safety, as it ensures that the seat belts are functioning correctly during a collision. When this code appears, it typically means that the vehicle may not properly detect whether the seat belts are fastened, potentially leading to safety risks. In addition to the potential for increased injury during an accident due to non-activation of airbags or seatbelt pretensioners, the presence of this code may also illuminate the airbag warning light on your dashboard. Ignoring this code can result in diminished vehicle safety and may lead to failed inspection tests in jurisdictions requiring operational seat belt systems. It is essential to address this issue promptly for the safety of all passengers and to ensure compliance with safety regulations.

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

Symptoms

Common symptoms when B016B is present:

  • The airbag warning light remains illuminated on the dashboard, indicating a potential safety issue.
  • The seat belt chime does not activate when the seat belt is unbuckled, which can lead to unsafe driving habits.
  • The vehicle experiences issues with the proper deployment of airbags during a crash due to sensor malfunction.
  • Inconsistent readings when attempting to buckle the seat belt; the system may not recognize the seat belt buckle as latched.
  • Error messages may appear on the onboard display, indicating a seat belt system fault.

Possible Causes

Most common causes of B016B (ordered by frequency):

  1. The most common cause is a damaged or corroded seat belt sensor connector, with about 40% likelihood. This can often be due to moisture exposure or physical wear.
  2. A short circuit in the seat belt sensor wiring is the second most common cause, accounting for around 30% of cases. This issue may arise from frayed wires or improper repairs.
  3. A third potential cause is a faulty seat belt tension sensor, which can result from wear and tear over time. Regular inspections can help prevent this.
  4. Less commonly, a malfunctioning Body Control Module (BCM) can cause this code, which may require professional diagnosis and is more complex to resolve.
  5. Rarely, issues with the vehicle's main computer system can lead to false readings, necessitating a thorough diagnosis to ensure all systems are functioning correctly.
