Thank you Rick150, I can't quite make out some of the areas in the diagram, is it possible to show where the tail lid connections are?
Thank you Rick150, this diagram appears to be centred around the Rear Window Button and Rear Window Handle Push Button. Is there also a diagram that shows the rear tailgate lid and the connection to the internal release button on the drivers door?
Hi, where can I obtain a wiring diagram for the tailgate, switches and sensors please? I think I have a serious electrical problem which prevents me from using the internal tailgate release switch and the remote control but the button on the tailgate appears to work fine as does the glass section.
I am not sure of the exact operation of a 2005 Cayenne so looking to this board for advice on whether this mode of operation is as per design or actually a fault. The issue I have is when I unlock the car using the remote keyfob, all doors open as expected but when I lock the doors, it appears that all doors lock except the tailgate (glass and main lid) I can still open these doors for a short time after the main car is locked. Then if I do go ahead and open either of the tailgate doors, the hazard lights start flashing but no audio alert as if to inform me that the car has been broken into. If I leave the car for a while after I lock the car then I can no longer open the tailgate so clearly the system is working but not as I expect it to. Is this as per design or actually a fault?
Thanks Rex, forgot to say that I recently replaced the PCM as the last one was completely broken. I have the same model (BE6654) but a slightly older revision 7l5.035.191H as opposed to 7l5.035.191K. How could I get the unit to refresh its brains? It also appears to be using data from where the previous owner lived even though it is nowhere near them anymore so to me it appears to be using data from the car rather than its own memory. Is this even possible?
My PCM2.1 is showing 6 or 7 satellites but displays an incorrect location in a completely different city to me. I have tried the 1-4-8 reset procedure but this hasn't helped. If it can see satellites, could there still be a problem with the antenna? For information, I also have a problem with the date and it displays the year 2000. When I go into the time/date settings on the PCM, it says "no GPS data is available" so I am really unsure whether true GPS data is available despite the unit seeing 6 or 7 satellites.
