WARNING: This page is about a different car, the 2014 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.
CHECK the vehicle history for recent service actions related to the BCM. If there have been recent service actions with the BCM, REPEAT the PMI procedure as directed by the diagnostic scan tool or CONFIGURE the PSCM using vehicle as-built data. If there have been no recent service actions, INSTALL a new EPAS gear to correct the failure to retain configuration data.
