BezerkR32 Posted February 20, 2011 Author Share Posted February 20, 2011 ok guys, having some issues bleeding the system. have gravity bled down to the bleeder at the pump, i then power the pump up and try to bleed at the box but not getting any pressure there. Is there a better way to do this? Link to comment https://www.sau.com.au/forums/topic/354116-m35-atessa-pump-replacement/#findComment-5680169 Share on other sites More sharing options...
scotty nm35 Posted February 21, 2011 Share Posted February 21, 2011 You need to take it to Nissan and get them to switch the pump and Attessa on with the Consult 3 to bleed it properly. This should be able to be done manually by hooking up 12v directly to the pump and solenoid but no-one has had the courage to try yet. I have the wiring diags here but they are in Japanese...

BezerkR32 Posted February 21, 2011 Author Share Posted February 21, 2011 yeh that is how i do the gtrs and it works fine, must be something else that requires switching in this system. where is the solenoid, i bet its shut.

Jetwreck Posted February 21, 2011 Share Posted February 21, 2011 when you figure this one out don't forget to post......best be is to get your car on a hoist with someone running the consult to turn it on and off!

KiwiRS4T Posted February 21, 2011 Share Posted February 21, 2011 ok guys, having some issues bleeding the system. have gravity bled down to the bleeder at the pump, i then power the pump up and try to bleed at the box but not getting any pressure there. Is there a better way to do this? When you say you power the pump up you mean you have the motor running? There is supposed to be a manual switch in fron to the driver's legs - will try to find the reference, Here is one: http://sites.google.com/site/tyndago/gt-rbleedingattesasystem Can this be the same switch that people are using to run in 2wd?

Duncan Posted February 21, 2011 Share Posted February 21, 2011 still not sure if m35 is the same as r32/r33/r34, but if it is, there is a second bleeder near the driveshaft/subframe as well as the gearbox.....try that one first you might have an airlock Link to comment https://www.sau.com.au/forums/topic/354116-m35-atessa-pump-replacement/#findComment-5681531 Share on other sites More sharing options...
Jetwreck Posted February 21, 2011 Share Posted February 21, 2011 There are the two bleed nipples....and on the back of the GB near the driveshaft and the other next to or on the pump!

Angus Smart Posted February 21, 2011 Share Posted February 21, 2011 Yew should be a pump somewhere around the drivers side on the rear subframe. and on the back of the box. that plug near the consult plug you short it out to ground?? the pump runs, (confirm with craig) do the pump bleed first, then move on to the rear of the box and do that bleed. then make sure the reservoir is up to the full line with no gap between.. or just pull the abs plug and f**k the 4wd all together Link to comment https://www.sau.com.au/forums/topic/354116-m35-atessa-pump-replacement/#findComment-5681540 Share on other sites More sharing options...
BezerkR32 Posted February 27, 2011 Author Share Posted February 27, 2011 i think you just disconnect the plug and the pump runs.....could be wrong. anyway it doesnt in my car atm. i powered up the pump and solenoid manually and bled the system, now have to see why the pump isnt being activated. anyone have a wiring diagram of the atessa system?

I bleed mine the other day.....all good As far as wiring goes you might find what you want in here. http://www.m35stagea.info/forum/viewtopic.php?f=2&t=43 The Engine control and ECU pinouts are translated....they might give you a small heads up....Have you had it plugged into a Consult yet?

KiwiRS4T Posted February 2, 2012 Share Posted February 2, 2012 Once in a lifetime? Its not under as much stress as an automatic gearbox - once per 100,000 should be heaps.
