What is B0C0E?

The DTC B0C0E code indicates an issue with the vehicle's body control module (BCM) related to the driver's door lock actuator. This trouble code typically arises when the BCM detects a malfunction in the circuit or component that controls the unlocking and locking of the driver's door. This can lead to several inconveniences, such as the inability to lock or unlock doors remotely or manually, which not only affects the security of the vehicle but can also lead to more significant electrical issues if left unaddressed. The B0C0E code is common in various models, particularly in 2015-2020 Jeep Cherokee and Dodge Durango, where such electronic components are heavily relied upon for functionality. Ignoring this code can lead to further complications, including difficulty in starting the vehicle, issues with the lighting system, and malfunctions in other electronic features. It's essential to have this code diagnosed and repaired promptly to maintain the overall safety and security of your vehicle.

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

Symptoms

Common symptoms when B0C0E is present:

  • Check engine light stays illuminated, indicating a need for diagnostic attention.
  • Inability to lock or unlock the driver's door using the remote key fob, leading to security concerns.
  • Door locks may work intermittently, causing frustration and potential safety risks.
  • Other electronic features, such as window controls, may become erratic, affecting overall vehicle functionality.
  • Battery drain issues may arise if the BCM is malfunctioning, leading to a dead battery.

Possible Causes

Most common causes of B0C0E (ordered by frequency):

  1. The most common cause for the B0C0E code is a faulty driver's door lock actuator, which occurs in approximately 60% of cases. This actuator controls the locking mechanism and can wear out over time.
  2. Wiring issues, such as damaged or corroded wires leading to the BCM, can also trigger this code. These problems often arise from exposure to moisture or road debris.
  3. Poor connections at the BCM or door lock actuator can lead to intermittent failures. Ensuring tight and clean connections can help prevent this issue.
  4. Less commonly, a malfunctioning BCM can cause this code. If the BCM is faulty, it may misinterpret signals from the door lock actuator.
  5. Rarely, issues with the vehicle's main harness can affect multiple components, causing errors like the B0C0E.
