Adaptive Steering Locking Solenoid
WARNING: This page is about a different car, the 2018 Ford F-550 Super Duty, 2018 Ford F-450 Super Duty, 2018 Ford F-350 Super Duty, and 2018 Ford F-250 Super Duty. However, it is still accessible from the selected car via links, so may be relevant.
The locking solenoid is a normally engaged (locked) solenoid which requires a voltage input to disengage (unlock). This provides a fail-safe in case of SECM or adaptive steering system failure.
