Rear Window Lockout Feature

The rear window lockout switch is built into the Driver Door Switch Assembly (DDSA). There are no external circuits. The lockout function is used to prevent the rear 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 interprets the flow of voltage through the switch as a lockout request. The DDSA sends the switch status, via the power door serial data circuit, to the driver door module (DDM). The DDM sends the request, via the power door serial data circuit to the rear passenger door modules. The rear door modules then prohibit the windows from being operated from their locally mounted window switches.

When the lockout function has been activated, the rear passenger door windows can still be operated from the driver door by using the window switches built into the DDSA
