What vehicles are most commonly affected by B0E6D?

The B0E6D code is frequently reported in models like the 2016-2020 Chevrolet Malibu, as well as various GM vehicles from 2015-2020. Always check for any recalls or technical service bulletins related to the BCM for your specific model.

How can I prevent B0E6D from happening again?

Regular vehicle maintenance, including inspections of the electrical system and lighting components, can help prevent the B0E6D code from reoccurring. Avoid aftermarket modifications to the lighting system to ensure compatibility with your vehicle's electronics.

What is B0E6D?

The B0E6D diagnostic trouble code (DTC) is a manufacturer-specific code that typically pertains to the body control module (BCM) and is often related to issues with the vehicle's lighting system. When a car's onboard diagnostic system detects a malfunction in the BCM or a related component, it triggers this code. The B0E6D code can indicate problems such as malfunctioning exterior lights, issues with the BCM's communication, or even faulty sensors connected to the lighting system. In practical terms, if your vehicle shows this code, you may experience symptoms like flickering lights, dashboard warning lights, or even a complete failure of certain lights. It's essential to address this issue as it can affect your vehicle's safety, particularly if it impacts headlights or brake lights. Ignoring this code could lead to more significant issues, including increased repair costs down the line, especially if the BCM or related components require replacement. If you're experiencing this code in your Chevrolet Malibu or similar vehicle, it's vital to diagnose and repair the issue promptly to avoid compromising your vehicle's safety features.

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

Symptoms

Common symptoms when B0E6D is present:

  • The check engine light or a specific warning light related to the lighting system stays illuminated, indicating a fault.
  • Exterior lights, such as headlights or brake lights, may flicker or fail intermittently, causing visibility and safety issues.
  • The vehicle's dashboard may display erratic readings or warnings, particularly related to the lighting system.
  • In some cases, the vehicle may experience electrical issues, like power windows not functioning correctly, due to BCM communication faults.
  • You may notice decreased battery performance or quicker battery drain if the BCM is malfunctioning and drawing excess power.

Possible Causes

Most common causes of B0E6D (ordered by frequency):

  1. The most common cause of the B0E6D code is a faulty body control module (BCM), which can occur in about 60% of cases. This can happen due to wear and tear or exposure to moisture.
  2. A damaged wiring harness or corroded connectors related to the lighting system is the second most common cause, accounting for approximately 25% of B0E6D occurrences. These issues can disrupt the electrical flow to the BCM.
  3. Faulty sensors related to the vehicle's lighting system may cause this code as well. Regular inspections can help prevent sensor issues, which is crucial for maintaining vehicle safety.
  4. Less common causes include software glitches within the BCM, which can sometimes be resolved with a simple software update from the dealer.
  5. Rarely, external factors such as aftermarket modifications to the vehicle's lighting system can trigger the B0E6D code, especially if incompatible components are used.
