Adaptive Steering Lock

WARNING: This page is about a different car, the 2017 Ford Edge. However, it is still accessible from the selected car via links, so may be relevant.

The adaptive steering system is designed with a locking device. While the lock is engaged, the steering system is set to a fixed (1:1) steering ratio. A sound may be heard when the vehicle is started or shut off as the lock is disengaged or engaged and a slight movement of the steering wheel may be noticed while the locking action is taking place. If the vehicle loses electrical power or the SECM detects a fault while driving, the lock is engaged. Extreme operating conditions may also cause the SECM to engage the lock. This strategy prevents overheating and permanent damage to the adaptive steering system. Typical steering and driving maneuvers allow the system to cool and return to normal operation. While the lock is engaged, it is possible the steering wheel may not be straight when the vehicle is driving straight ahead and the driver may notice the steering wheel angle or "clear vision" may be off-set.

The locking solenoid also engages when the ignition is set to ON and the driver door is closed, this prevents the steering wheel from turning unnecessarily while the system is off and affecting steering wheel clear vision. The locking solenoid disengages once the engine is started.
