Window Lockout Feature

The window lockout switch is built into the driver door switch assembly (DDSA). The lockout function can be personalized to either, 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.

The DDSA internally supplies the voltage and ground to the contacts of the lockout switch. When the lockout switch button is momentarily pressed, the normally open contacts are closed to ground, the LED indicator on the button 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 to prohibit the windows from being operated from their respective switches. The passenger door windows can still be operated using the appropriate window switch built into the DDSA.
