What is B01F2?

The diagnostic trouble code (DTC) B01F2 indicates a malfunction within the airbag system, specifically related to the passenger-side airbag. This code is commonly found in various vehicles, including the 2015-2020 Honda Accord and 2016-2021 Toyota Camry. When this code is triggered, it typically means that the airbag control module has detected an issue that could potentially prevent the airbag from deploying during a collision. The implications of a B01F2 code can be serious, as it compromises the safety features of your vehicle. Symptoms often include the airbag warning light illuminating on the dashboard, indicating to the driver that there is a fault in the system. Ignoring this code can lead to unsafe driving conditions, especially since airbags are crucial for passenger safety during accidents. It's important to address this issue promptly to ensure that the airbag system is fully operational. If you see this code, a thorough diagnostic and inspection of the airbag system should be your next step, as it could involve checking wiring, connectors, and the airbag module itself.

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

Symptoms

Common symptoms when B01F2 is present:

  • The airbag warning light remains illuminated on the dashboard, signaling a malfunction in the airbag system.
  • The passenger airbag may not deploy in the event of an accident, leading to increased risk of injury.
  • Unusual noises or clicks may be heard from the airbag control module area, indicating a potential wiring issue.
  • Intermittent warning signs may appear, such as the airbag light flashing and then returning to a steady state.
  • In some cases, the airbag system may reset temporarily, but the B01F2 code will eventually return.

Possible Causes

Most common causes of B01F2 (ordered by frequency):

  1. The most common cause of B01F2 is a faulty airbag sensor, occurring in approximately 60% of cases. This sensor can fail due to wear and tear or exposure to moisture.
  2. Another potential cause is damaged wiring or connectors in the airbag system. This issue can result from physical impacts or corrosion over time.
  3. A less frequent cause may involve issues with the airbag control module itself, which can occur in older vehicles or those that have suffered water damage.
  4. In rare cases, a software glitch in the vehicle's onboard computer may trigger the B01F2 code, necessitating a software update or reset.
  5. Lastly, installing aftermarket seats or accessories that interfere with the airbag system can also lead to this DTC being triggered.
