WARNING: This page is about a different car, the 2018 Ford Edge. However, it is still accessible from the selected car via links, so may be relevant.
The BECMB supplies system voltage to the RCM and OCSM, based on HS-CAN1 inputs and the ignition input.
The BECMB requires PMI when being replaced. Refer to the diagnostic scan tool instructions to carry out PMI.
