What is B1055?
The diagnostic trouble code (DTC) B1055 indicates a malfunction related to the Body Control Module (BCM) in your vehicle. This code is commonly found in models like the 2015-2018 Honda Accord and other vehicles equipped with a sophisticated electronic system. The BCM is responsible for managing various electronic functions such as lighting, power windows, and door locks. When the BCM detects an issue with its internal circuitry or if there are communication problems with other modules, it triggers the B1055 code. This can lead to several noticeable symptoms, including the failure of interior lights, issues with keyless entry systems, or non-functioning power accessories. Real-world implications of this code can vary, but ignoring it may lead to more significant electrical issues, potentially affecting vehicle safety and performance. If you experience this code, it's essential to have a certified technician diagnose the issue to prevent further complications.
System: B - Body (Airbags, Lighting, Security, Climate Control)
Symptoms
Common symptoms when B1055 is present:
- The check engine light or another warning indicator remains illuminated on the dashboard, indicating an electrical issue.
- Power accessories such as windows or doors may not function correctly, leading to a frustrating user experience.
- Interior lights may flicker or fail to operate, impacting visibility and convenience within the vehicle.
- Keyless entry systems may malfunction, making it difficult to enter or secure the vehicle.
- In some cases, the vehicle may experience intermittent electrical issues, leading to unpredictability in operation.
Possible Causes
Most common causes of B1055 (ordered by frequency):
- The most common cause of the B1055 code is a faulty Body Control Module, with a likelihood of around 60%. Issues can arise due to age, exposure to moisture, or electrical shorts.
- A second common cause may be damaged wiring or connectors associated with the BCM. This can occur from wear and tear or physical damage, leading to communication failures.
- Corrosion at electrical connections can also contribute to this code. Regular inspections and maintenance can help prevent such issues.
- Less commonly, software malfunctions or programming errors in the BCM could trigger this code. Ensuring the module is updated can mitigate this risk.
- A rare but serious cause of the B1055 code is a failing battery or alternator, which can lead to insufficient power for the BCM's proper operation.
