What is B0F65?

The diagnostic trouble code (DTC) B0F65 is primarily related to issues within the vehicle's body control module, commonly seen in vehicles like the 2016-2019 Honda Pilot and 2017-2019 Acura MDX. This code indicates that there is a malfunction within the body control system that may affect various functionalities such as power windows, door locks, and interior lighting. When this code is triggered, it may lead to symptoms that can significantly impact the user experience and overall vehicle safety. The body control module (BCM) is responsible for managing several electronic functions in modern vehicles, and a failure can lead to features that may stop working or operate erratically. Ignoring the B0F65 code can lead to further complications, such as draining the battery or affecting other electronic systems in your car. The average cost to diagnose and repair issues related to this code can range widely depending on the underlying cause, but it often falls between $150 and $800. It is crucial to address this issue promptly to ensure your vehicle remains reliable and safe to drive.

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

Symptoms

Common symptoms when B0F65 is present:

  • The check engine light may be illuminated, indicating an underlying issue that requires attention.
  • Power windows may not operate correctly, either failing to open or close as expected.
  • Interior lights may flicker or remain on longer than usual, leading to potential battery drain.
  • Door locks may function erratically, either failing to lock or unlock with the remote or switch.
  • The vehicle's alarm system may trigger unexpectedly or fail to activate, posing a security risk.

Possible Causes

Most common causes of B0F65 (ordered by frequency):

  1. The most common cause of the B0F65 code is a faulty body control module (BCM), which occurs in approximately 60% of cases. This can happen due to electrical short circuits or software malfunctions.
  2. Another frequent cause is damaged wiring or connectors between the BCM and other components, which can lead to communication failures.
  3. Corrosion on electrical connectors is a less common cause, but it can significantly impact the BCM's functionality. Regular inspection of the vehicle's electrical system can help prevent this issue.
  4. A malfunctioning sensor, such as a door or ignition switch, can also trigger this code, although this is less common.
  5. In rare cases, a software glitch or outdated firmware in the BCM can lead to the B0F65 code, necessitating a software update from the dealer.
