12V (batt +) on pin-1 & 0V (batt -) on pin-3 briefly wathcing which way the window goes. If it tries to go down, reverse the wires. The other pins are used by the outstation & BECM for blockage / trap detection, so you don't need them for manual closing.

You don't. Simply connect 12V to the motor until the window reaches the top & disconnect the wires. Start by applying 12V for 1-2 seconds & see which way the window moves. Do it in stages makinbg sure you disconnect at the top to avoid burning the motor out or jamming the mechanism. If...

If you search for the connector number it shows you. C1565 on page 590 of that link you posted. SW & SG are the wire colours (page 14) if you need to identify the pins.

What size was the skirting & wood blocks ?

Then it's not the complete version. My copy is 5199 pages, but the ISO version is much easier to navigate. There's a website here with all the PDF's from RAVE. https://github.com/IRusio/Range-Rover-P38/blob/main/pdf/RR%2096MY%20Electrical%20Troubleshooting%20Manual.pdf

Electrical Troubleshooting section. Try searching the PDF for "Power Windows". Then skip to page 1590 or thereabouts.

It's the left one in this picture . . . . . but an Auto probably will not have the wiring for it.

As said in post #4 you really need to download RAVE. It's all in there. Hint 1 & 3

If you re-test the brake switch using a multimeter, you should see the 0-12V & 12V-0V switch on both contacts immediately. Nanocom takes a few seconds to register the state, hence why you might sometimes see open-open & closed-closed. Remember it's reading them in sequence, not at the same...

Another thought or two. Does the handbrake light work ? Maybe a bulb failure there causes the other two to light up ? Also have you re-checked wheel bearings, CV joint & the sensors are properly pushed in ?

Two more things to verify: 1) Do the mirrors move correctly or are they also not working ? 2) Does the car lock & unlock normally ? Either of both of these require power to the door outstations, so if they are working then you probably have 12V & ground to each front door & fuses F9 & F22 are...

1) is the issue on all windows or only 1 or 2 ? 2) Probably not a good idea to "short circuit" anything. You can apply 12V directly to the motor, but unplug it first. 3) For the one-touch window closing, rather than the fob, try with the key, i.e. turn & hold the key in the lock position...

For the connections from ABS to BECM, there are three wires in addition to the K-Line to the diagnostic connector. Looking in the Nanocom & BECM SID documents, these are what the signals are for. It is not clear in any of the documents if the ABS & ETC lines are actually serial data, or...

Rather than the Utility menu, what are the Inputs doing ? Check them when stationary and up to 5mph & then >> 5mph.

icarsoft CR Max does not do P38 settings. Their "coverage" says it does most of the ECU's but I have tried it, and it has limited coverage. It also identified the AT box as diesel, but gets the engine correct as GEMS !! Nothin else connects. Same thing with my Delphi CDP.
