B036E is frequently reported in 2015-2018 Honda Accord, Chevrolet Malibu, and Ford Fusion models. Be sure to check for any recalls or Technical Service Bulletins (TSBs) related to these vehicles.

How can I prevent B036E from happening again?

Regular maintenance, including checking electrical connections, keeping the wiring harness free of corrosion, and avoiding aftermarket modifications, can help prevent the occurrence of B036E.

What is B036E?

The diagnostic trouble code (DTC) B036E signifies a fault detected in the Body Control Module (BCM), specifically related to the vehicle's lighting system. This code is often triggered when the BCM detects inconsistencies in the operation of the vehicle's exterior lights or interior functions like the power windows, door locks, or other electronic components. When this fault occurs, it can affect not only the operation of your lights but also the overall functionality of the vehicle's electrical systems. The BCM is responsible for communication between various electronic components, and a failure can lead to symptoms such as malfunctioning lights or erratic behavior of electric accessories. Ignoring this code can lead to more extensive electrical issues, potentially leaving you stranded or causing safety concerns if your lights fail while driving. In many cases, this code is seen in popular makes like Honda, Chevrolet, and Ford, particularly in models produced between 2015 and 2018. Addressing the B036E code promptly can help ensure the reliability of your vehicle’s electrical systems and maintain safe driving conditions.

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

Symptoms

Common symptoms when B036E is present:

  • The check engine light illuminates continuously, indicating possible electrical issues.
  • Exterior lights may flicker or fail to operate, affecting visibility.
  • Interior features like power windows or door locks may malfunction intermittently.
  • Electrical accessories may behave erratically, leading to an unreliable driving experience.
  • Increased battery drain may occur due to malfunctioning electrical components.

Possible Causes

Most common causes of B036E (ordered by frequency):

  1. The most common cause is a faulty Body Control Module, which has a likelihood of around 60%. This can be due to internal failure or software issues.
  2. Wiring harness issues or short circuits account for approximately 25% of cases, often due to wear and tear or exposure to the elements.
  3. Corrosion at connectors can lead to intermittent signals; keeping these connections clean can prevent this issue.
  4. Less common, but serious, is a failure in the power distribution module, which can affect multiple systems.
  5. A rare cause involves external factors such as aftermarket modifications that interfere with the BCM's normal operation.
