Code B0968 2018 GMC Sierra Description

The parking assist system can be activated and deactivated by pressing the parking assist switch. The Parking Assist Control Module applies voltage and monitors the parking assist switch signal circuit. The parking assist switch is a normally open switch. With the switch open, the voltage seen at the front and rear Parking Assist Control Module is high. When the parking assist switch is pressed, the switch is closed, and the signal circuit is pulled to the ground. With the switch closed, the voltage seen at the front and rear Parking Assist Control Module is low. The Parking Assist Control Module will respond to this by activating or deactivating the parking assist function. The Diagnostic Trouble Code (DTC) will be set when the Parking Assist On/Off Switch circuit is not to factory specifications.
