Circuit/System Description

The parallel parking assist can be activated and deactivated by pressing the parallel parking assist switch. The Parking Assist Control Module applies voltage and monitors the parallel parking assist switch signal circuit. The parallel parking assist switch is a normally open switch. With the switch open, voltage seen at the Parking Assist Control Module is high. When the parallel parking assist switch is pressed, the switch is closed and the signal circuit is pulled to ground. With the switch closed, voltage seen at the Parking Assist Control Module is low. The Parking Assist Control Module will respond to this by activating or deactivating the parallel parking assist function.
