What is B0F37?

The B0F37 diagnostic trouble code (DTC) is associated with issues in the vehicle's body control module (BCM) or related systems, particularly in models like the 2015-2018 Honda Accord. This code often indicates a malfunction within the vehicle's multi-information display or other integrated systems that manage features like ambient lighting and door locks. When this code is triggered, it suggests that the BCM has detected an irregularity in its communication with other modules, which can lead to a range of operational issues. Ignoring this code can result in intermittent failures of electronic features, such as the inability to lock or unlock doors, malfunction of the dashboard lights, or even failure of the vehicle to start. Owners may notice that certain electrical components behave erratically, which can cause frustration and concern regarding the overall reliability of the vehicle. Addressing the B0F37 code promptly is crucial to maintaining the integrity of your vehicle’s electronic systems and ensuring a safe driving experience. If you find this code, it’s advisable to begin a thorough diagnostic process to pinpoint the exact cause and implement a suitable repair.

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

Symptoms

Common symptoms when B0F37 is present:

  • The check engine light illuminates or remains on, indicating that the vehicle's computer has detected an issue.
  • Some electronic features, such as power door locks or interior lights, may not function correctly, leading to inconvenience.
  • Inconsistent operation of the vehicle’s dashboard displays, which can be distracting and potentially hazardous while driving.
  • The vehicle may experience starting issues, where it intermittently fails to start or respond to the key.
  • Unusual electrical behavior, such as flickering lights or unexpected warnings on the dashboard, which can indicate deeper issues.

Possible Causes

Most common causes of B0F37 (ordered by frequency):

  1. The most common cause for the B0F37 code is a faulty body control module (BCM), which has a 60% likelihood of being the issue. This can occur due to age, exposure to moisture, or electrical shorts.
  2. Another potential cause is damaged wiring or connectors related to the BCM, which can disrupt proper communication between modules. This is often due to wear and tear or improper installation during repairs.
  3. A third cause could be software issues within the BCM that may need an update. Regular software checks can prevent these from occurring.
  4. In rarer cases, the problem might stem from a malfunctioning ignition switch, which can lead to power interruptions affecting the BCM's functionality.
  5. Lastly, although less common, it is possible that the issue arises from a failed communication with other modules, which can complicate diagnostics.
