Ignition Switch - Without Push Button Start

The ignition switch is a multiple position rotary switch that is controlled by a lock cylinder and a key. The switch is hardwired to the BCM  , PCM  and the Brake Shift Interlock Actuator (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.
