Rear Window Lockout Feature

The rear window lockout switch is built into, and receives power and ground from, the Driver Door Switch Assembly (DDSA). There are no external circuits. The lockout function is used to prevent the passenger door windows from being operated from their locally mounted switches. When the lockout switch is pressed momentarily, the switch contacts are briefly closed, the LED indicator on the switch button is illuminated, and the DDSA processes this switch signal. The DDSA sends the switch status, via class 2 serial data message, to the passenger door modules. The passenger door modules then prohibit the windows from being operated from the locally mounted passenger door window switches. When the lockout function has been activated, the passenger door windows can still be operated from the driver door by using the window switches built into the DDSA.
