Circuit Description

WARNING: This page is about a different car, the 2007 Hummer H2. However, it is still accessible from the selected car via links, so may be relevant.

If the vehicle is equipped with a floor mounted console gearshift, an ignition lock cylinder control actuator system is used in the steering column. The purpose of the system is to prevent the ignition lock cylinder from being turned to the lock position while the transmission is in gear, this also prevents the steering wheel from being locked. The system consists of an ignition lock cylinder actuator and a park position switch. The actuator contains a pin that is spring loaded out, to prevent the ignition lock cylinder from being turned to the lock position when the gearshift is not in Park. The park position switch is located in the floor mounted gearshift assembly, as part of the automatic transmission shift lock control switch. The switch is closed with the gearshift in PARK, and open in all other positions
