Window Lockout Feature

The window lockout switch is built into the Driver Door Switch Assembly (DDSA). The lockout function can be programmed to prevent both rear windows from being operated from their locally mounted switches, or, to prevent all of the passenger windows from being operated from their locally mounted switches. When the lockout switch button is momentarily pressed, the normally open contacts of the lockout switch are closed, the LED indicator is illuminated, and the DDSA interprets the switch signal. The DDSA then sends a message, via the power door serial data circuit, to the driver door module (DDM) indicating that the switch is active. The DDM then sends a message, via the power door serial data circuit, to both rear door modules to prohibit the rear windows from being operated from the rear door window switches, or, sends the message to all of the passenger doors to prohibit all passenger windows from being operated from their respective switches. When the lockout function has been activated, the passenger windows can still be operated from the driver door by using the window switches built into the DDSA.
