Steering Effort Control Module (SECM)
WARNING: This page is about a different car, the 2021 Ford F-150. However, it is still accessible from the selected car via links, so may be relevant.
The SECM contains the ECU for the adaptive steering system. The ECU monitors all sensor inputs and HS-CAN2 messages relating to the adaptive steering system and directly controls the output of the adaptive steering motor. The SECM is internal to the steering wheel and is serviced with the steering wheel.
