WARNING: This page is about a different car, the 2018 Lincoln Navigator. However, it is still accessible from the selected car via links, so may be relevant.
DTC U045A:00 indicates a concern with the PAM or vehicle communications network. The module reporting this DTC is not the problem module. Do not install a new PSCM as part of the repair for DTC U045A:00.
When the PSCM sets this DTC power steering assist is present, but active parking assist is disabled.
The presence of DTC U045A:00 prevents the active park assist system (if equipped) from activating. If set during an active park assist event, the event is terminated and the active park assist system is deactivated.
