Circuit/System Description

The child door lockout switch on the driver front side door window control switch controls the child locks on the rear doors. The lockout switch is an input to the driver front side door window control switch and the body control module controls the left rear and right rear child lock actuators. When the body control module receives a command from the driver front side door window control switch, it will apply 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.
