Window Lockout Feature

The window lockout switch is part of the DDSA. 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 the switch signal. The DDSA sends the switch status via GMLAN serial data 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. the front passenger window can be personalized to operate when the window lockout function is active.
