Circuit/System Description

The child door lockout switch is on the driver door lock/window switch and controls the function of the rear interior door handles as well as the function of the rear window switches. When the BCM receives a command from the window lockout switch, it will apply voltage to the door lock security relay coil, this will energize the relay and the contact within the relay will then direct the voltage to lock the left rear and right rear child locks and then isolate them from the normal door lock system to prevent the rear doors from being opened by using the interior rear door handles.
