Hello, I have a BCNR33 and the car is not pulling all 4 wheels. The rear left tire seems to be the only one making power. I checked and my Attesa pump is not coming on and I checked for power to the pump and there isn't any. I checked fuses and I need a wiring diagram of which relays run the system. I replace the relay that's in the trunk (boot) and no change. I also had a leaking pressure switch on the pump so I spliced in another one. If anyone have any ideas of why the pump isn't getting power please share inputs. 20180209_205017.jpg

If as per your heading you have a V spec then the rear LSD is computer controlled so if its single wheeling you need to fix that first. I believe the V spec attessa control is different as well but don't know much about the V spec. Again you may be able to extract fault codes from the relevant ecus.

Yes it's different. I don't know if power is even at the ECU. I would like to see a diagram of the system if anyone has it by any chance. Yes the pump and ECU controls the torque split between the wheels. Thanks for the input brother
You need a Consult scan tool or equivalent first.  Codes can tell you a lot.  Not finding the ATTESA computer on the network at all is diagnostic in itself!
True..I might have to run to Nissan which I'm sure they would have one

Problem solved... It was the pressure switch. My buddy and I swapped ECU, Attesa relay, checked each other's fuses, made sure things were getting power and I ground a wire and it came on. So I knew then the system wasn't dead [emoji879]️. So I had a pressure switch that I spliced in from another pump and wallah she came on. The pressure switch is not meant to be separated from the pump but I made it happen.

    • Mixing things up - installed some leather recaros to match the leather seat covered rear seats. Interior looks pretty schmick now except for some slight wear on the steering wheel which I will monitor and address if it becomes worse or actually noticeable!

    • I'm normally copping my own abuse from neglecting my daily drivers. "Those suspension bushes will last a bit more", "Don't worry about the oil leak, just keep topping it up". The project cars I'm always doing things slowly on them as I'm wanting them to be done better, and neater, and nicer. Luckily I don't have to deal with 18 year old Matt's "Learning to wire" stuff in the project cars. And there's only one piece of wiring I'm displeased about in the Landcruiser, and it's about to be cut out... However, the box loads of parts that have been going through this place lately for the Landcruiser... Brake pads Brake Rotors Full handbrake overhaul Wheel Bearings Seals Swivel hubs Steering Boxes Half the suspension joints Shocks Air bags (Ones to go in the rear springs for towing) Water pump Timing kit Lower timing case Harmonic Balancer Radiator Lots of other little seals and shits Gas struts for the bonnet New power window switches And god knows what else I've forgotten... Ha ha ha I have my fingers crossed the pinion seals don't start leaking on the diffs, that the transfer case doesn't leak, and the gearbox input shaft doesn't leak, nor the rear main seal. As they're about the only seals I haven't replaced in the driveline! I'm seriously eyeing off buying new caliper rebuild kits front and rear brake calipers... I'll probably recheck all the valve clearances soon too, and hopefully, it should be all good and sweet to haul some long distance trips again!
    • Every time I pull my 3x gauges out of the console and see the crack-addict way that I did the wiring, and I just can't bring myself to tear it all apart and "make it nice", because it is currently working. In fact, the last time I was in there I probably made it worse.
