Power Steering Control Module (PSCM)
WARNING: This page is about a different car, the 2021 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.
The PSCM is the ECU for the EPAS system. The module monitors all sensor inputs and HS-CAN messages that relate to the EPAS system and directly controls the output of the EPAS motor.
