Interesting.... thanks for the update....

yes i agree thanks for the update as my problem seems exactly like yours. and having had a front accedent the abs sensors playing up make perfect sense (and what all the mechanics and auto electrician's keep guessing). is your diagnostic fault code still coming up as the pressure switch though?

I must admit though that ABS sensors would make even more sense if:

a) 'pressure switch (77)' wasn't being reported in the ATTESA diagnostic

b) the ABS light stays on when you start the car (indicating an ABS fault), because a faulty ABS sensor should trip an ABS fault (there are plenty of failsafes for that)

no warning lights..... dont know about the codes didnt check em out

dropped the car off today and the guys at tenagah motorsport had rung them and told them all about it.. so i had to say nothing but "send the bill to dvg maddington" lol

and they said i will definatly have it back by friday and will tell me evrything they find.. so i can put it up here.

cool... still hoping we might find out what that infernal clicking is all about :) surely the money is on the pressure switch... has to be the pressure switch... :thumbsup:

no abs light just 4wd light but atessa and the abs sytem use the same sensors and are heavily linked together(and code 77)

That's true I guess, although ABS is 'mission critical', and any sensor error should cause the ABS light to come on...? Sorry what do you mean about the code 77 - does that relate to ABS too? or you mean you are getting code 77?

ok some one help.....

it is showing a 73, 74 code which is the ET-s/Lsd actuator motor... but there are no waring lights........

they thought it was the pressure switch or the asb sensors but it isnt..

i have rung heaps of places and they dont seem to know...

any ideas??

Hmm that sounds like the ATTESA pump? Duncan, anybody else have a better idea?

I'm no auto electrician, but I'd start with the relay and check that it's actually switching power at its output, then check that that output appears at the ATTESA pump harness. If no power to the ATTESA pump, faulty relay (or wiring/earth connection). If power at the ATTESA pump... well... could be expensive (could be the pump itself).

But I think playing swapsies with the relay is the first point of call (because it's cheap if a volunteer is available and should give a result very quickly), and definitely reset the ATTESA fault codes (short some pins - details here somewhere, search for 'attesa diagnostic').

nope they siad it definatly isnt the realy

i dont care what it costs to fix it cause it is under wattanty... but i have really had enough waiting....

they say the 4wd all works fine...

Well if you have them replace the whole ATTESA pump assembly (of which I am pretty sure the pressure switch is integral), you might fix it :)

here gos they are replacing the es-t/lsd actuator motor.... it sits on top of the rear diff...

and costs about $1,100.. plus fitting.... so an expensive exercise.. but warranty is paying...

Cool :happy: You actually managed to convince them to do it... that's gotta fix it...

  • 2 weeks later...

ok latest update....lol

not the actuator motor :bunny: has been now also been to northside nissan.. they knew nothing ....

so took it to c-red... it looks like it is the ecu for the attesa syatem... goes back on the 9th of june to have an ecu from a rear half cut to see if that fixes it.. hope it does.. will keep you posted guys.. i just want my car fixed im so over it..

Wow, that's a lot of stuff you're having replaced :blink:

But this is really invaluable stuff for some of us other stag' owners... do I understand right that you have had the whole attesa system replaced and that hasn't fixed it? that rules out a lot of things.... some of which are cheap and I was betting on to fix my problem :D thanks for posting your progress, I'm interested to see where this leads... and hoping that you find a solution to make your stag smoooth and quiet like it should be :D

hi,

I`ve got the same problem on my ENR33. e-ts relay clicking like mad in boot while hot, silent when i start the car in the morning. No warning lights...

I am afraid that it is e-ts control unit that is faulty :ermm:. There was an issue with it last summer -- damn guys who changed the film on the rear window pour some water on the e-ts unit :happy:.

messanic, hope you will your problem and explain us how to do it.

My Attessa plays up a bit from cold (its engaged when I haven't selected it but it comes right when the car has warmed up) so I thought i would change the fluid. I went to the Nissan dealer and asked if they had a special fluid for the Atessa or could I use ATF (because I got a 20L Fuchs Titan ATF 4000 semi-synthetic to change mtygearbox oil) but they said no its a special Nissan fluid the same as the nissan power steering fluid. I don't necessarily believe them so I will go to another Nissan Dealer and ask them the same question. Otherwise I will just bleed the system. Has anyone done this and noticed any difference?

    • Ok glad you clarified on the frenchy’s options , I was worried about if my oem hoses would fit the new compressor or not if I just bought the bracket/compressor kit ,  didn’t realize they also sold a larger full conversion kit. Hmm may just go oem in that case then to make it easy only because I plan to sell this car to upgrade to a 32 GTR or 34 GTT.
    • Right, here's a video of the basic operation at least.  This is what you can expect day to day when you turn the car on and it boots from standby.  The only thing from a media point of view I haven't gotten working is for it to autoplay plexamp when it turns on from standby (it works from cold boot) but that's more of a plexamp problem as it will autoplay other music players.  Also attached is my one stray cable.  It's part of the screen's wiring adapters but there's just nowhere for it to go in my car.  I've just now done a bit of research and found a matching port on a 2010-2014 head unit with BOSE.  Mine has no BOSE so that's that case pretty much closed I think.  Plugging in the Infiniti AC panel basically did nothing for me, so that's a dead end as well.  Next port of call is to mess with this CANBUS module and see what I can find from it.  I found this resource containing the DBC files for a 2010+ G37 : https://github.com/icecube45/Dash_InfinitiG37/blob/master/InfinitiG37.dbc I'll now have something to go from when I try to extract my CANBUS data so I can see if the HVAC Mode, Fan Speed, Temperature, etc. match and also the gear shifter position.  It's a pretty big assumption that it's just mismatched CAN signals but considering all the devices in the CAN network are talking to each other (AC can be fully adjusted just with no info on screen) it might be a safe one.  I will report back WhatsApp Video 2025-02-26 at 12.49.10.mp4
    • Thanks for that Paul.  Do you think if I posted a picture you'd be able to remember where it went? 
    • Sorry Duncan, I didn't get a notification for the replies.  Thanks for responding!  It's a full Android device, but does allow you to use CarPlay/AA as well.  This is the one I bought from NaviRS on AliExpress: https://www.aliexpress.com/item/1005006368602668.html?spm=a2g0o.order_list.order_list_main.111.59aa1802JDzQ0E - the 2K 8G-256G CAM variant but it seems to have gone up by £170 since I bought it!  My purchase was £307.14.   It's not the fastest thing in the world but performs perfectly adequately.  It stays on standby unless I disconnect the battery and let it power down, then it's just a fairly standard Android bootup time from cold.  The DSP Equaliser is very nice and made the standard stereo system sound pretty decent compared to the stock screen.  Perhaps I can take a video of it when I get a sec. It *allegedly* supports the reverse camera, but I'm yet to get that working.  It has options for reverse cam (a camera unit can be bought separately) or 360 cameras (also bought separately).  To be fair it doesn't seem to detect that the shifter was put into reverse but I'm working on a theory about this as well.  At the moment I'm going without which is a bit annoying considering the car is an absolute canal barge but so far I haven't caused any damage I'll grab a picture of the wire I'm missing later today when I can get outside.  My theory, by the by, is that not only is the head unit different, but the CANBUS network has different signals for the different years.  I think this because I have a spare AC panel from a newer Infiniti G37 (as opposed to my Nissan panel) which wouldn't control anything except the volume when I had it wired up with the stock system.  I'm going to throw it back in and see if the screen will respond to it.  I've just ordered an arduino CANBUS module so I can have a look at the signals going around the car and see if I can spot anything.  I'm thinking if I can work out what it's expecting vs what it's getting I might be able to translate and relay the signal back but so far just a theory anyway. I also found this on my travels, so far the only one that specifically matches my car: https://www.aliexpress.com/item/1005002822934280.html?spm=a2g0s.imconversation.0.0.33433e5fgttovi If you look at the picture of the before, it has the card reader slot, and the picture of the head unit is exactly the same as the one pictured in my original post.  I asked if they sell the cables separately but sadly they won't.  I didn't want to just buy this one because it's a super old Android version and only dual core - likely slow as hell. 
    • As above, you did refill the coolant and burp the system before running it again didn't you?
