Cannot believe I have not had time to get this sorted yet, said I would do it in April, anyways.
My Rover 75 has a lazy locking/venting feature, hold the key in the door unlock position and all windows will open. Hold the key in the door lock position, all windows close. I love this feature, especially when walking away and notice a window open, or it is so hot the leather takes the skin off your back. Tap a RF unit into the 75's BCU lazy locking and venting windows up/down request pins, for wireless remote control windows.
The Freelander being designed by MG Rover, I am surprised (that I can find) that the CCU does not have this feature, even though not featured, I though maybe it uses the same BCU/CCU, but it appears not.
Going by part number is no good in this case.
According to the schematics, the only window I can send a signal to from the CCU is the back door window request pins (CCU D170) C0428-10 tail window up, and (CCU D170) C0428-11 tail window down.
I cannot find anything for lazy locking/venting in the CCU schematics. Does anyone know if I have missed anything. Are lazy locking/venting pins there on the CCU unconnected, or a non existent optional feature on the Freelander, and the CCU just controls the windows individually. Come the spring I intend to tap into the CCU for ideas I have, but I don't have time to fiddle about taking it out just for a look see.
My only other option seems to be a reversing polarity RF unit. Button A will send + signal from terminal 1, and a - signal from terminal 2, button B will reverse the signal polarity from terminals 1 & 2.
From what I can see, the only place to do this is the drivers door window switches, the single relay RF unit being the size of a matchbox, will easily fit into the void under the switch.
Tap into the eight passenger doors pos & neg window wires, connect them to the RF unit set to non latching, so SWMBO cannot accidentally leave the RF unit relay closed. Button A will open all the windows, button B will close all the windows, for as long as the buttons are depressed. The RF relay being normally open will not cause any feedback I assume.
