What is B0FFB?
DTC B0FFB is a diagnostic trouble code that indicates a malfunction related to the vehicle's body control module (BCM). This code can arise from a variety of issues, including faulty sensors, wiring problems, or communication errors within the vehicle's electronic systems. When the BCM detects an inconsistency, it triggers the check engine light and stores this code in the vehicle's onboard diagnostic system. For car owners, this can lead to several issues, such as malfunctioning lights, erratic dashboard readings, or even problems with starting the vehicle. It's essential to address this code promptly, as ignoring it could lead to further complications, including increased repair costs and diminished vehicle safety. The B0FFB code is particularly common in models like the 2017-2023 Chevrolet Equinox and GMC Terrain, where electronic components play a critical role in vehicle performance. Regular diagnostics using tools like the GeekOBD APP can help identify the root cause of this code and ensure your vehicle runs smoothly.
System: B - Body (Airbags, Lighting, Security, Climate Control)
Symptoms
Common symptoms when B0FFB is present:
- The check engine light stays on constantly, indicating a persistent issue that needs attention.
- Dashboard lights may flicker or malfunction, leading to an inaccurate display of vehicle conditions.
- The vehicle may experience intermittent electrical failures, such as power windows or locks not functioning properly.
- Unresponsive or erratic behavior from the vehicle's infotainment system, including navigation and audio controls.
- Difficulty starting the vehicle, which could indicate a problem with the BCM's communication with the ignition system.
Possible Causes
Most common causes of B0FFB (ordered by frequency):
- Faulty body control module (BCM) - 40% likelihood. The BCM may be malfunctioning due to wear and tear or manufacturing defects, which can lead to various electrical issues.
- Wiring issues - 30% likelihood. Damaged or corroded wiring can disrupt communication between the BCM and other components, triggering this code.
- Sensor failures - 15% likelihood. Components like door sensors or lighting sensors may fail, causing the BCM to trigger a fault code.
- Electrical shorts - 10% likelihood. Shorts in the wiring harness can create erratic signals, leading to the B0FFB code.
- Software glitches - 5% likelihood. Occasionally, a software update may be needed to resolve communication errors within the vehicle's control modules.
