Repair costs can range from $100 for wiring repairs to $800 for a complete BCM replacement. It's advisable to get a thorough diagnostic to determine the exact cause before proceeding with any repairs.

Can I drive my car with B1057 or should I stop immediately?

While it may be possible to drive your vehicle with the B1057 code, it is not recommended. Continuing to drive could lead to further electrical issues and may compromise safety features. It's best to have the vehicle inspected and repaired as soon as possible.

How can I diagnose B1057 myself using GeekOBD APP?

Using the GeekOBD APP, you can connect to your vehicle's OBD2 port to read the B1057 code. Follow the prompts in the app to retrieve freeze frame data and additional codes. This information will help you understand the context of the problem, allowing for a more informed approach to repairs.

What vehicles are most commonly affected by B1057?

The B1057 code is most commonly seen in 2010-2020 Ford F-Series, Chevrolet Silverado, and GMC Sierra models. It's important to check for any manufacturer recalls or technical service bulletins (TSBs) related to your specific vehicle model that may address this issue.

How can I prevent B1057 from happening again?

To prevent the B1057 code from recurring, ensure regular maintenance of your vehicle’s electrical systems. Check for any signs of corrosion, especially in connectors, and ensure that the BCM is well-protected from moisture. Regular inspections and using quality parts during repairs can also help.

What is B1057?

The B1057 diagnostic trouble code (DTC) is a specific code that indicates a malfunction in the automotive body control module (BCM) related to the power door locks or other body functions. This code usually appears in vehicles like the 2010-2020 Ford F-Series and Chevrolet Silverado models. When this code is triggered, it means that the BCM is not receiving or sending signals correctly, which can lead to issues such as malfunctioning door locks, lighting problems, and erratic behavior of electrical components. In practical terms, this means that drivers may experience symptoms such as doors failing to lock or unlock, dashboard lights flickering, or even intermittent failures of other electronic features like windows or mirrors. Ignoring this code can lead to further electrical issues or even complete failure of the BCM, which can be expensive to replace. Therefore, it is essential to address the B1057 code promptly to ensure the reliability and safety of your vehicle's electronic systems.

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

Symptoms

Common symptoms when B1057 is present:

  • The check engine light or warning light related to the body control module remains illuminated.
  • Power door locks fail to operate, either not locking or unlocking with the key fob or interior switch.
  • Dashboard lights may flicker or fail to illuminate properly, indicating a potential electrical issue.
  • Windows may not operate as expected, either failing to respond to switches or moving erratically.
  • The vehicle's alarm system may trigger unexpectedly or fail to activate when locking the doors.

Possible Causes

Most common causes of B1057 (ordered by frequency):

  1. Faulty body control module is the most common cause of the B1057 code, with a likelihood of around 60%. This could be due to internal circuitry failure or software glitches.
  2. Damaged wiring or poor connections can also trigger this code, accounting for about 25% of cases. Corroded connectors or broken wires can disrupt signals between the BCM and other components.
  3. Moisture intrusion into the BCM can cause intermittent faults, making it a frequent but less common issue (10%). Preventing water damage through proper sealing is crucial.
  4. Electrical shorts in the door lock circuits could also lead to this code, with a likelihood of 3%. This is often due to wear and tear over time.
  5. Rarely, a malfunctioning key fob or issues with the remote start system can trigger the B1057 code.
