What is B07E2?
The diagnostic trouble code B07E2 indicates a malfunction in the Body Control Module (BCM) of your vehicle. This code is commonly triggered when the BCM detects a fault in its communication with other modules or when it cannot perform its intended functions. The Body Control Module is responsible for controlling various electronic systems in your car, including lighting, remote keyless entry, and power windows. When B07E2 is present, you may experience symptoms like malfunctioning lights, issues with power accessories, or even problems starting your vehicle. For instance, many owners of the 2016 Ford Fusion and 2018 Chevrolet Malibu have reported B07E2 alongside erratic behavior of their vehicle's electrical components. Ignoring this code can lead to further electrical failures and more costly repairs down the line. Therefore, it’s crucial to address this issue promptly to ensure the longevity and proper functioning of your vehicle’s electronic systems.
