Body Control Module (BCM)

WARNING: This page is about a different car, the 2022 Ford Police Interceptor Utility and 2022 Ford Explorer. However, it is still accessible from the selected car via links, so may be relevant.

The BCM provides the WACM with signals to determine when to enable charging. For example, Ignition_Status and Delay Accy are used to enable wireless charging as a controller of the charge request. Another function of the BCM is to tell the WACM when an interior key fob search is about to take place. The BCM utilizes a Field-Effect Transistor (FET) to short the line the WACM receives from the BCM to vehicle battery. When this occurs, the WACM disables the charging function to make sure it does not interfere with key fob searches.
