Sorry forgot to attach this on the Accessory Delay Module

RETAINED ACCESSORY POWER (RAP)

SERIAL DATA CONTROL OF RETAINED ACCESSORY POWER (RAP)
Retained accessory power (RAP) is a vehicle power mode that permits the operation of selected customer convenience items after the ignition switch is turned OFF. These selected items will remain in operation until a passenger compartment door is opened or until the RAP function timer reaches its shut-off limit. The modules listed below all receive a RAP message from the dash integration module (DIM) over the serial data circuits. The DIM monitors the ignition switch position, battery condition and passenger compartment door status to determine whether RAP should be initiated. The DIM then sends a message to the listed modules telling them that they are in RAP power mode. The modules then support the operation of the systems under their control as required by their RAP power mode strategy.

RAP will end when one of the following conditions are met:

The DIM receives an input as a serial data message from any door module indicating the opening of a passenger compartment door.
The DIM receives a message from its internal timer indicating the end of the RAP period after 10 minutes.
The DIM detects a decrease in battery capacity below a prescribed limit.
The transition from OFF to RUN/ON or ACC of the ignition switch.
The DIM module then sends a serial data message to the listed modules ending the RAP function.

The modules receiving serial data messages for RAP functions are:

The driver door module (DDM)
The front passenger door module (FPDM)
The left rear door module (LRDM)
The radio
The rear integration module (RIM)
The right rear door module (RRDM)
The TV antenna module
The vehicle communication Interface module (VCIM)
RELAY CONTROL OF RETAINED ACCESSORY POWER (RAP)
When the rear integration module (RIM) is in the RAP function as described above, it actuates the RAP relay. This provides power during the RAP period for, the sunroof control module w/CF5.

The RIM deactivates the RAP relay to end the RAP function when it ends the RAP function as outlined in the previous text.

In my Cadillac CTS 2003 Only the driver can open and close the four windows.
Passengers can't neither open nor close their windows with their switch. Their windows must be opened and closed by the driver. Could you help me to solve this problem?

Start by checking for bad motors. Turn the key on and check by holding the switch for the window to go down. As you bang on the door panel under the armrest. The ones that start working have bad window motors. If it doesnt help you will need to start checking voltages and wiring. Thanks for using 2carpros

I have a 2003 cadillac CTS and the rear passenger window will not go up. I heard it pop a while ago and haven't used it since, but forgot about it tonight and put it down and now it will not go back up. When I hit the switch, I can hear it engage but the window will not go up.

I've tried to put the window up manually while pressing the up button but it still won't budge at all. When I hold the window and try to put it down it makes a grinding sound and then it will make the same sound going back up until it gets the the point of the window and it stops.
