What is B0D96?
DTC B0D96 indicates a malfunction within the Body Control Module (BCM), which is crucial for managing various electronic functions in your vehicle. This code is often seen in Honda and Toyota models, especially those manufactured between 2015 and 2020. When B0D96 is triggered, it typically signifies that the BCM is not communicating effectively with other modules or that it has detected an internal fault. This can lead to issues such as malfunctioning lights, power windows, or even problems with the vehicle's security system. The BCM plays a vital role in controlling functions such as door locks, interior lights, and anti-theft systems. If left unresolved, a B0D96 code can lead to more significant electrical issues, impacting the overall reliability and functionality of your vehicle. Many drivers report symptoms like erratic behavior of electrical components, persistent warning lights, and even difficulty starting the vehicle. It is crucial to address this code promptly to avoid complications that may arise from a malfunctioning BCM.
System: B - Body (Airbags, Lighting, Security, Climate Control)
Symptoms
