What is B0208?

The diagnostic trouble code B0208 indicates a problem with the body control module (BCM). This code is commonly found in various vehicle makes, especially in models from Honda and Ford, manufactured between 2005 and 2018. The BCM is responsible for controlling various electronic systems in your vehicle, such as lighting, security, and climate control. When the BCM detects an issue, it logs the B0208 code, signaling a malfunction. Common symptoms of this code include issues with the power windows, door locks, and dashboard lights. Ignoring this code can lead to further electronic issues, including the risk of locking yourself out of your vehicle or experiencing complete failure of electronic systems. If you notice the B0208 code, it's essential to address it promptly to prevent more serious problems down the line. In most cases, resolving this code involves inspecting the BCM, wiring, and related components for faults or damage. It's advisable to use a reliable OBD2 scanner, like the GeekOBD APP, to gather more information about the error and its context.

Symptoms

Common symptoms when B0208 is present:

  • The check engine light illuminates, indicating an underlying issue with the body control module.
  • Power windows may fail to operate, causing inconvenience when trying to adjust ventilation.
  • Dashboard lights flicker or remain off, leading to difficulty reading important vehicle information.
  • Remote keyless entry may stop functioning, preventing access to the vehicle.
  • The vehicle's interior lights may fail to turn on or off automatically, resulting in battery drain.

Possible Causes

Most common causes of B0208 (ordered by frequency):

  1. The most common cause is a fault in the body control module itself, with a likelihood of around 50%. This can be due to age or manufacturing defects.
  2. Another potential cause is damaged wiring or connectors associated with the BCM, which can happen from wear or environmental factors.
  3. Corrosion at electrical connectors can also trigger the B0208 code, so it is important to regularly inspect and clean these areas.
  4. Less common but serious is a software issue within the BCM that may require reprogramming or replacement of the module.
  5. Rarely, issues with the vehicle's battery, such as low voltage, can lead to intermittent BCM faults, causing the B0208 code.
