What is B1010?

The B1010 diagnostic trouble code (DTC) indicates a fault in the Body Control Module (BCM) of your vehicle, which is responsible for managing various electrical systems, including lighting, door locks, and other accessories. When this code appears, it typically signifies that the BCM is detecting an issue, such as a malfunctioning component or a communication failure within the system. For instance, this code is common in vehicles like the 2010-2015 Chevrolet Equinox and the 2013-2017 Ford Fusion. If the BCM is not functioning correctly, you may experience various electrical issues, such as flickering lights, non-functioning power windows, or even a failure to start the vehicle. Ignoring this code can lead to more significant issues down the line, including a complete failure of the electrical system. Therefore, it's crucial to address the B1010 code promptly to ensure your vehicle remains reliable and safe. Regular diagnostics can help catch issues early, and using tools like the GeekOBD APP can aid in identifying the root cause of the code effectively.

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

Symptoms

Common symptoms when B1010 is present:

  • Check engine light illuminates and stays on, indicating a persistent issue that needs attention.
  • Power windows may fail to operate, leading to difficulties in controlling airflow and ventilation inside the vehicle.
  • Interior lights flicker or do not turn on, which can be quite unsettling, especially during nighttime driving.
  • Non-functioning door locks, causing security concerns as you may not be able to lock or unlock the vehicle remotely.
  • Inconsistent performance of turn signals, leading to potential safety hazards on the road.

Possible Causes

Most common causes of B1010 (ordered by frequency):

  1. The most common cause of the B1010 code is a faulty Body Control Module, occurring in about 60% of cases. This could be due to internal component failure or software issues.
  2. A second common cause could be poor electrical connections or damaged wiring, which can account for around 25% of B1010 occurrences. Inspecting and repairing wiring can often resolve this.
  3. A third cause might be a blown fuse related to the BCM, which is a simple fix but often overlooked. Regular checks can prevent this issue.
  4. Less commonly, a failed sensor that communicates with the BCM may trigger this code, requiring replacement of the sensor.
  5. Rarely, a software glitch or update issue could cause the BCM to set a B1010 code, which may require a dealer-level reprogramming.
