R32 Attesa Problem

Hello!

I know there are a lot of attesa posts here but i never found something for my problem (correct me if im wrong).

On my car the 4x4 and the abs light is on, so i checked the attesa fluid in my trunk and it was way under the minimum and i thought that may be the problem! So i refilled it with an oil with the same caracteristics as NISSAN MATIC D. Then i opened the bleed nipple in front to bleed the system unplugging the plug behind the drivers kick panel. Doing that i hear the relais in the trunk clicking five times but nothing else happens! So i tried shorting the red and the yellow cable on the relais and the pump starts priming but no oil comes out the bleeding nipple.

I then bought a new battery and tried with that.

The first time i started the car with the bleeding nipple open the pump started priming and oil came out. I switched the car off and closed the bleeding nipple and retried but nothing happened and the 4x4 and abs light was still on. Since i had to close the bleeding nipple while the oil was coming i thougt now there may be air in the system. Now i retried starting the car but again the pump was not priming and again shorting the relais makes the pump prime but nothing comes. The pump even sounds like its priming without oil but the resevoir is filled.

I hope someone can help me and sorry if i made any mistakes!

Hi mate, firstly, the 4wd and ABS lights won't come on due to a bleeding problem. But having said that, it sounds like you also have a problem with how the system was bled. Is this car new or have you always had this problem?

To bleed it you should fill the reservoir, disconnect that plug which should start the pump, and then open the bleed nipple near the end of the transfer case. Fluid will flow (eventually...), once it is bubble free close the nipple. You may also need to follow the same procedure with the bleeder nipple above the rear driveshaft in the same line.

As for the actual problem....when the ABS/4wd lights are on the error code should be flashing on the computer under the rear parcel shelf on (on the right) through a small LED. Check out how many times it is flashing and check which code that is in the GTR workshop manual.

When i unplug the plug the pump does not react only sometimes the relais clicks for 3 times and thats about it.

I checked the LED and watched it for 2 minutes or more but the light switches on every 4 second! But no quick or slower flashes is that normal?

wellllllll.....page C-67 says that the error code flashes every 3-4 seconds....so in theory it might be throwing code 1 which is front right wheel speed sensor. Should be easy enough to do a physical check of the sensor at the hub, the wiring to the hub in the wheel well and there is a plug where it plugs into the main loom in the engine bay on the strut tower under the throttle cable. CH-70 shows full troubleshooting for code 1.

Or it's just misleading and the light is not trying to tell you 1

Thank you ill check that later! May the speedsensor just be unplugged or do i have to replace it?

Hope it works because i tried a lot and i dont understand why my pump does not work even it worked when i plugged in the new battery!

 

I post a video with the error code of the ecu so you can check!

Update!

Thanks Ducan you were right the speedsensor was unplugged!

When my car came there was a lot of stuff unplugged and the moment i read your comment it came it my mind that maybe the sensor was also unplugged! I opened the bonett and the first thing i see is a unplugged plug that goes in the wheel well ! I facepalmed for abou 10 seconds!

 

Thank you!!

well well....I'm never really sure I trust 30 year old error/troubleshooting, but there you go, it was spot on with a very easy solution.  Great to hear.

you know it's possible there shouldn't be that many unplugged plugs in an engine bay

yeah i found a black one right next to it but i was not able to find the right plug for it

Yeah i know, i bought a car from a unreliable seller and when it came some stuff was unplugged from the turbo and my car made 0,3 bar and the seller didnt even know that

For the abs and 4x4 lights he said i have to plug in the pc for diagnostics and it will reset the lights  so you see the guy who sells the cars here in italy had no plan what he was talking about

Thank you and have a nice weekend!
