Window Lockout Feature

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