Component Description: PSCM
WARNING: This page is about a different car, the 2017 Lincoln Navigator and 2017 Ford Expedition. 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 PSCM monitors all sensor inputs and HS-CAN messages relating to the EPAS system and directly controls the output of the EPAS motor.
The PSCM and the steering gear are serviced as an assembly. When a new PSCM and steering gear are installed, the module receives vehicle configuration information from the BCM.
