What is B0F41?

The diagnostic trouble code (DTC) B0F41 is primarily associated with the Body Control Module (BCM) and is often seen in vehicles like the 2016-2020 Ford Explorer and Lincoln MKX. This code indicates a failure in the rear seat control module communication, which can lead to various issues, including malfunctioning rear seat functions or problems with the rear climate control system. The BCM plays a crucial role in managing electrical systems in your vehicle, and when it fails to communicate correctly with the rear seat module, it can trigger the B0F41 code. This can manifest as a check engine light, or it may even result in the rear seats not reclining or adjusting properly. The real-world implications of this code can affect passenger comfort and convenience, potentially leading to safety concerns if rear occupants cannot adjust their seating properly. Ignoring this code could result in further electrical issues, so it’s essential for car owners to take it seriously.

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

Symptoms

Common symptoms when B0F41 is present:

  • Check engine light illuminated, indicating a fault in the electrical system.
  • Rear seat adjustments (like reclining or moving) are unresponsive or malfunctioning, causing discomfort for rear passengers.
  • Rear climate control system may not function correctly, affecting comfort during drives.
  • Frequent electrical issues within the vehicle, like flickering lights or malfunctioning power windows, may also occur.
  • Strange noises from the rear seat area when trying to adjust settings, indicating a possible mechanical failure.

Possible Causes

Most common causes of B0F41 (ordered by frequency):

  1. The most common cause is a faulty rear seat control module, which occurs in about 50% of cases. This can happen due to wear and tear or electrical shorts.
  2. A damaged wiring harness connected to the BCM can lead to communication issues, often caused by wear from repeated motion or exposure to moisture.
  3. Corrosion at electrical connectors can prevent proper communication. Regular maintenance and inspections can help avoid this.
  4. Less commonly, a failing Body Control Module itself may require replacement, which, although rare, can be a more expensive repair.
  5. In rare instances, software glitches within the BCM or rear seat module can trigger this code, necessitating a software update.
