What vehicles are most commonly affected by B0961?

The B0961 code is frequently reported in models like the 2015-2020 Ford F-150 and other Ford vehicles equipped with similar BCM systems. Check for recalls or technical service bulletins (TSBs) related to your model.

How can I prevent B0961 from happening again?

Regular maintenance checks, ensuring proper sealing of electrical connectors, and avoiding aftermarket modifications can help prevent recurrence of the B0961 code.

What is B0961?

The diagnostic trouble code (DTC) B0961 indicates a malfunction related to the Body Control Module (BCM) in your vehicle. This code specifically points to a problem with the BCM’s communication or functionality, which is crucial for managing various electrical systems, including lights, locks, and the alarm system. When the BCM detects an anomaly, it triggers the B0961 code, often resulting in warning lights on the dashboard and potential malfunctions in the vehicle's electrical systems. For instance, if you own a 2015-2020 Ford F-150, experiencing this code may lead to issues such as non-functioning door locks, inoperable lights, or problems with the vehicle’s security system. Ignoring this issue can lead to more severe electrical failures, impacting safety and drivability. The underlying causes can range from faulty wiring and connectors to software issues within the BCM itself. Addressing this code promptly is essential to ensure all electronic systems in your vehicle operate correctly and reliably.
