Ignition Switch
WARNING: This page is about a different car, the 2013 Ford Explorer. However, it is still accessible from the selected car via links, so may be relevant.
The ignition switch is a multiple position, rotary switch that is controlled by a lock cylinder and a key. The switch is hard wired to the BCM-B , PCM and the BSIA .
The key removal inhibit solenoid (also known as the key release interlock actuator) is an electronically controlled solenoid that prevents the ignition lock cylinder from being turned to the OFF position unless the gear selector lever is in the PARK position. The key removal inhibit solenoid is part of the ignition switch.
