Body Control Module (BCM)

WARNING: This page is about a different car, the 2013 Ford Explorer. However, it is still accessible from the selected car via links, so may be relevant.

The BCM  is responsible for checking the identifications from both the RFA  module and the PCM  . It also controls the ignition states and determines if the engine should be started or turned off depending upon input from the start/stop and brake switches and if a programmed Intelligent Access (IA) key is inside the vehicle. The RFA  module sends a MS-CAN  message to the BCM  indicating if a programmed Intelligent Access (IA) key is inside the vehicle.

If the BCM  is replaced, the two parameter reset procedures must be performed to enable PATS  . The two parameter reset procedures are between the BCM  and RFA  module, and the BCM  and PCM  .
