Steering Column Control Module
WARNING: This page is about a different car, the 2023 Ford Bronco Sport. However, it is still accessible from the selected car via links, so may be relevant.
The SCCM controls the steering wheel heating elements. The SCCM uses the steering wheel temperature sensor to maintain the steering wheel temperature. The SCCM is designed to remain on, heating the steering wheel and maintaining temperature until switched off using the HVAC or the ignition is turned off.
The SCCM requires PMI when replaced.
