What is B08C0?

The diagnostic trouble code B08C0 indicates a malfunction related to the vehicle's security system, specifically linked to the door lock and unlock functions. This code is primarily triggered when the Body Control Module (BCM) detects an issue with the communication or function of the door lock actuators or related components. Commonly found in vehicles such as the 2015-2018 Honda Accord and the 2016-2019 Ford Escape, the implications of this code can lead to the inability to lock or unlock doors remotely or manually. This can significantly affect the security of your vehicle, making it vulnerable to theft if not addressed. In addition to the security risks, you may also experience issues with the vehicle's alarm system, which could lead to false alarms or malfunctions. Drivers might notice that their key fob does not work as intended, or they may have to resort to using the physical key to unlock doors. Ignoring this code could lead to further complications within the vehicle's electrical systems, so it’s crucial to diagnose and resolve the underlying issue promptly.

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

Symptoms

Common symptoms when B08C0 is present:

  • The key fob fails to lock or unlock doors consistently, requiring manual operation.
  • The vehicle may emit random alarm sounds, indicating a malfunction within the security system.
  • Dashboard warning lights may illuminate, particularly related to the security or door lock systems.
  • The driver's door lock may operate intermittently, leading to frustration and potential security risks.
  • Remote start features (if applicable) may also become inoperative due to security system malfunctions.

Possible Causes

Most common causes of B08C0 (ordered by frequency):

  1. The most common cause of B08C0 is a faulty door lock actuator, with a likelihood of about 45%. These components can wear out over time or suffer from electrical issues.
  2. Another likely cause is a malfunctioning Body Control Module (BCM), which may fail to communicate properly with the door lock system, accounting for approximately 30% of cases.
  3. Wiring issues, such as frayed wires or poor connections, can also trigger this code, with a 15% chance of occurrence. Regular inspections can help prevent this.
  4. Less common, but still possible, is the failure of the key fob itself, which can result in a 7% likelihood of triggering the B08C0 code.
  5. In rare instances, software issues within the BCM can cause this code to appear, demanding a software update or reprogramming by a professional service.
