Power Windows Description and Operation

The vehicle is equipped with power windows controlled by the door modules. The DDM receives a window switch request, over the power door serial data circuit, from either the passenger door module wired to the window switch pressed, or from the Driver Door Switch Assembly (DDSA). The DDM checks the Class 2 serial data to see if the status information is correct, i.e. ignition switch position, to permit window operation. If the status information to permit window operation is correct, the DDM sends the command to the door module controlling the window to move the window as requested.

The power windows may be operated whenever the vehicle is in the Retained Accessory Power (RAP) mode, or, whenever the ignition switch is turned to the Accessory or Run positions.
