1. Navigate to 09 - Cent Elec - Long Coding
2. A drop-down list allows for 3 slave controllers to choose from. Keep the first one selected (0 - BCM) and click Long Coding Helper.
3. Select Byte 4 and enable Bits 5 & 6
4. Press Esc and click Do It.
5. Click Long Coding again, select (2 - RLS) and click Long Coding Helper.
6. Select Byte 0 and enable Bit 2
7. Press Esc and click Do It.
In the MFD/MFI you will see a new setting in the Convenience menu that is pre-enabled for this option, called 'Rain Closing'.
The car must be locked for this feature to work. The windows and/or sunroof will be closed when either (1) the rain-sensor detects water on the windscreen, or (2) 24 hours elapses since you locked the car. The windscreen wiper stalk must be in the intermittent/automatic position.
