Re: Power Window Relay
Hi Jalal,
I scanned the long list of mods done to the Red Bull and didn't see the power window delay. I take it this is one mod that still requires doing. That picture which shows the BCM, where did that come. I incorrectly thought the BCM was under the centre console just behind the gear selector unit. Further reading of the ESM shows yet another 'Black Box'. The diagram for the Series 2 shows 12 volts ignition going into the BCM on pin 3, I was thinking about a bypass at this point. Do you know if any other T31 of either series has sucessfully had this completed. It has really become one issue I would like to cure. As much as I would like to do this, I'm a bit hesitant without having the correct manual.
John

Re:
Hi John,
Yeah, I haven't done this mod as yet and based on my research no one has either.
The BCM is located behind the passenger side glove-box.

Re: Power Window Relay ( My Series 3 BCM is missing)
Hi Guys,
I thought with a couple of extra days off, that I would look seriously at the Power window delay for the Series 3. I left my passenger in the Xtrail with their window down and radio on while I went to look at shop in an arcade. We had one of those sudden downpours and any pushing of the window button, he didn't get any response. Wet passenger, wet inside, Not Happy Jan!
First step: Locate Body Control Module and ascertain if wiring is the same as in the Series 2 ESM.
This is now my second day and I'm now convinced it doesn't exist. Here is where I have looked.
1: In and behind the Glove box area where Jalal's post shows it. Series 2 perhaps. The bracket is there but no BCM.
2: In the passenger side kick panel area where the ECM used to be. ( Now Connector Central)
3: Drivers side kick panel
4: Behind and to the side of the Multimedia unit.
5: Under the dashboard both to the left and right of the column. Used a web cam to look at places I couldn't see with the lower dash panel removed.
6: Under in the IPDM module in the engine bay.
Going from the picture of the BCM in the ESM, it would have to be nearly 200mm long, 150 mm wide and 40mm deep, not something that you could easily hide. Pity really, I have already worked out how I was going to do it, and one thing for sure, the windows would also operate in Accessory mode.
PS On another note, when I had the glove box out, it does have a small bulb attached to light it. Comes on with the parkers.
John

Re: Power Window Relay
Hi Guys,
Our resident electronic genius has done it again! 
John (Johngqld) has deciphered the BCM (Body Control Module) of our Series 3 and 4 and managed to create a time delay relay unit which can be connected/wired-up to the BCM and introduce a 45-47 seconds delay and availability of power for you to operate all windows (and even the sunroof). The windows will also operate in ACC which is handy when you are parked in the driveway and working on the car.
John has first tested his unit on his car for many weeks and sent me a unit which I fitted on my Series 4 yesterday and I can confirm that it is working perfectly and made me feel like am sitting in my T30 Chrome Beast all over again LOL 
The BCM is indeed behind the glovebox which must be removed and you can see the BCM held by a metal bracket as seen below:
And here is the time delay relay box John manufactured which is now sitting right next to the BCM and all wired-up.
Awesome stuff John and thanks a million!

Re: Power Window Relay Series 3 and 4
Hi Guys,
You may have seen my earlier post where I was unable to locate the BCM. This was due to me not being able to turn my head a full 360 degrees, it wouldn't have helped back then as the Series 3 BCM is different to the earlier versions.
The BCM is a switching centre which takes in small control voltages checks if the conditions are correct and gives a high current output or sends the info on the CAN to where it is required. Your lights, wipers, door switches, just to mention a few, are controlled here as is the power for the windows. It also contains the relay which switches the power to the windows.
I have been running the delay on the windows since mid January and have used it on many occasions. The windows also operate with just the Accessories on and we have set the delay to 45 seconds internally as Xtrails exported to Mexico have this feature using 45 seconds. Why Mexico and not ours, someone in Nissan likes tacos? Finally my 2010 Xtrail now has the same features my 1997 EL Falcon had as standard.
Unfortunately this mod is not Plug and Play as you guys had with the T30 delay. I appreciate not all those who would be interested in this mod can solder, so we have come up with a C shaped clamp which requires you to only remove the insulation from the supply wire(yellow) and Blue wire (to windows). Fit the clamp around the cable and screw it down, add insulation tape for protection. The fuse under the bonnet for the windows is 50 Amps and a reasonable sized cable is run to the BCM. Just short of the BCM the cable is joined to a small one of approx 15 amps to go in and out of the BCM. Each motor draws about 3 to 4 amps, but this can rise to 11 amps when it stalls fully up or down after a period of time. Mr Nissan is relying on the fact you don't live next door to Homer Simpson and that your family won't stall all 4 windows at the same time.
A second issue is warranty. As all of our Series 3 and 4 Xtrails are still under warranty, you may wish to give this some thought as to any issues that may arise from you installing this. I think that as we are not cutting any cables (sorry Jalal), this may not be an issue.
Where to from here?
We have produced a step by step installation guide and Jalal and I feel most people should have no problems at all and we will make this available on the forum in a couple of weeks. I am currently waiting on some PCB's to arrive and we can look at times from there. If we are only looking at a small number of units we shouldn't have too many problems in supplying these. We can also just supply bare pcb 's to those who want to make the project for themselves as we have put together a spreadsheet of parts from Jaycar. I haven't looked at the cost per unit yet, but according to the Lewis Duckworth system, I don't think too much.
To answer Scot's question, the same unit will work on Series 1 and 2 however the wiring would need to be checked for accuracy to the manual before I would give it the go ahead.
It was a long day at work, sorry for the delay in the reply. My thanks to Jalal for his time and effort that has allowed us to bring this to you.
John

That is correct John. This is a warranty affecting mod for sure, so all those fitting it must be aware of this and weigh-up their options accordingly.
