    Hi @Rick150, so the black wire coming out of relay 433 is connected to several other large black wires, it is this connection that I am querying as funnily enough there is also a problem with the starter motor. It doesn't start 1st time, always needs to be cranked 2 or 3 times before the car will start. The starter motor tries to start the engine then dies then I hear the starter motor spinning freely without engaging the flywheel then it finally starts the car. Given that relay 433 is connected to the car's ignition system, could this explain the reason behind this particular problem?

    Hi @Rick150So after some troubleshooting, I found the dredded corroded wire syndrome near the battery - all the spliced connections have some corrosion. In total there are 5 pairs of wires. I haven't yet repaired them but wondered if you could let me know which wires do which function ? There are several large black wires all connected together but I think brown is ground on this car, not black?

    Thank you @Rick150. How do you actually test a ground point please? Also do you have the other part lf the previous wiring diagram I attached please? Many thanks

    @Rick150, do you happen to have the rest of this diagram please and how the rear comfort unit connects to the front of the vehicle? I have done some extensive troubleshooting but still cannot locate the fault. The switch in the drivers door has voltage and the swotch itself is fine so I expect the problem lies between the front control units and the rear but I don't know where the cables are run to see whether there is a break somewhere i.e.under the transmission tunnel/centre console or the passenger footwells - do you know this information? Clearly there is power going to the rear tailgate and soft close unit as both are functional when the button on the tailgate is depressed. So I am running out of options. Any ideas what or where I should test next? The only other observation is that, despite replacing the battery for a brand new battery, the instrument panel seems dim and flickers, is this a sign of a malfunction or battery drain somewhere? Many thanks for all your help!

    Hi @Rick150, I think your diagrams are spot on as I can find most of the parts you indicated. However, what I need to trace is button 17 in the diagram below right through to the tailgate actuator. Looking at your earlier post, the wiring going into this switch appears to have the same colour code as the "Right Rear Door Central Locking Button" and the "Left Rear Door Central Locking Button" but the button itself is not called either one of these; instead it is called the "Rear Lid Release" (part #95561315900). I can't seem to trace the wiring from this switch right through to the "Rear Comfort Systems Control Unit" and out to the "Rear Lid Actuator". Are there any additional diagrams you can offer ? Many thanks

    Thanks @Rick150, do all cars have a tilt sensor as I couldn't see one on mine when I looked yesterday or could it be built into the actual locking mechanism as shown on the diagram as for some reason there are some electronics within the lock (not the actuator). There are three wires going into the lock with pins HR, VR and Term 31. Do HR and VR correspond to Horizontal and Vertical positions? Also, if the sensor was sending bad signals back to the control unit, wouldn't the car send a warning message to the driver indicating that the tailgate is open whilst driving? There is nothing called a tilt sensor shown on this exploded diagram (please bear in mind that my tailgate is not self opening).

    Hi @Rick150, thank you for these diagrams, they are very useful. Looking at the last diagram you posted, the wires appear to go into a "Rear Comfort Systems Control Unit" (Right Rear Cargo Area). Do you happen to know where I can find this unit and is it prone to going bad ? I saw a module with the reference number: 7l0959933 is it this one ? many thanks

    Thanks Loren. Is there also a procedure available?

    Please can someone kindly point me in the right direction for a tutorial on how to remove the tailgate trim to get to the micro lid switch please? I couldn't find a tutorial anywhere so hoping someone can help. Many thanks

    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?
  13. Willow5
    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?
  14. Willow5
    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.

    Hi, please can you provide a code for a BE6654 radio? The serial number is 55020390 from a cayenne. Many thanks
