What is B0B0C?

The DTC B0B0C code refers to a communication issue within the automotive electrical system, specifically indicating that there is a fault with the power management control module (PMCM) or its related components. When this code appears, it signals that the vehicle's onboard diagnostic system has detected a malfunction in the PMCM's ability to communicate effectively with other modules, such as the engine control module (ECM) and the body control module (BCM). This can lead to various operational issues, including erratic electrical performance, failure of certain electronic features, and even potential battery drain. In real-world terms, this might manifest as problems with starting your vehicle, dimming headlights, or malfunctioning dashboard gauges. It's important to address the B0B0C code promptly, as ignoring it can lead to more significant electrical system failures and leave you stranded. Commonly found in vehicles like the 2016-2021 Ford Fusion, the B0B0C code can stem from a range of underlying issues, including wiring problems, poor connections, or faulty modules. By understanding what this code means, you can take the necessary steps to diagnose and repair the underlying issue effectively.

Symptoms

Common symptoms when B0B0C is present:

  • The check engine light is illuminated, indicating a general fault within the electrical system.
  • Electrical accessories, such as windows or locks, may operate inconsistently or fail to respond.
  • The vehicle may experience difficulty starting, with intermittent cranking or complete failure to start.
  • Dashboard warning lights may flicker or behave erratically, providing inaccurate information to the driver.
  • Dimming or flickering headlights can occur, especially when other electrical components are in use.

Possible Causes

Most common causes of B0B0C (ordered by frequency):

  1. The most common cause of the B0B0C code is damaged or corroded wiring in the electrical harness, with a likelihood of around 40%. This can occur due to exposure to moisture or wear over time.
  2. Another potential cause is a faulty power management control module itself, which can fail due to internal circuit issues or software glitches. This accounts for approximately 30% of cases.
  3. Poor connections at terminals or connectors can lead to intermittent communication failures. Regular maintenance checks can help prevent this issue, with a likelihood of about 20%.
  4. Less commonly, a failing battery can cause voltage issues that affect the PMCM's performance, contributing to the B0B0C code. This has a 5% likelihood.
  5. A rare but serious cause could be a malfunction within the engine control module (ECM) that affects all communication, which can be costly and complex to diagnose.
