What is B05CE?

The diagnostic trouble code (DTC) B05CE indicates an issue related to the body control module (BCM), particularly a malfunction in the system that controls various electrical components within the vehicle. This may include lighting, door locks, and power windows. When this code is triggered, it often signifies that the BCM is unable to communicate effectively with other modules or is detecting a fault in its own operations. For car owners, this means potential problems with the vehicle’s electrical features, leading to inconveniences like malfunctioning lights, non-responsive locks, or even issues with starting the vehicle. It's important to understand that while this code may not immediately affect the engine's performance, it can lead to significant inconveniences and safety risks if left unresolved. The B05CE code is often seen in various models, including the 2015-2018 Honda Accord, as well as some Ford vehicles and other brands. Owners should be vigilant for any electrical anomalies and address them promptly to avoid further complications. Ignoring this code could lead to a complete failure of the BCM, which can be costly to replace and repair.

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

Symptoms

Common symptoms when B05CE is present:

  • The dashboard warning lights, including the check engine light, may illuminate unexpectedly, indicating an electrical fault.
  • Power windows may function inconsistently or fail to respond, causing frustration for drivers and passengers alike.
  • Door locks might not respond properly, requiring manual operation or leading to security concerns.
  • Electrical accessories such as interior lights may flicker or not operate at all, which can be particularly concerning at night.
  • Occasional starting issues may arise if the BCM has trouble communicating with the ignition system.

Possible Causes

Most common causes of B05CE (ordered by frequency):

  1. The most common cause of the B05CE code is a faulty body control module, which has a likelihood of around 60%. This can occur due to wear and tear or exposure to moisture.
  2. A short circuit in the wiring harness connected to the BCM is another potential cause, often resulting from damaged insulation or corrosion, with a likelihood of about 25%.
  3. Poor connections at the BCM plug can lead to intermittent faults, which can be prevented by regular inspections and ensuring all connections are secure.
  4. Less common but serious causes include water intrusion into the BCM housing, which can lead to complete module failure if not addressed quickly.
  5. Rarely, a software glitch within the BCM can trigger this code, requiring a software update or reprogramming as a solution.
