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! :D

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 :P

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! :D:D:D

 

Thank you!! :D

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:13_upside_down:

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 :D

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

Thank you and have a nice weekend! :1_grinning:

      From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.

      Place the new daughterboard in the case and mount it using the 3 small black rivets provided, and reconnect the 3 factory ribbon cables to the new board Then, use the 3 piggyback cables from the daughterboard into the factory board on top (there are stand offs in the case to keep them apart. and remember to reconnect the antenna and rear cover fan wires. 1 screw to hold the motherboard in place. Before closing the case, make a hole in the sticker covering a hole in the case and run the cable for the android unit into the plug there. The video forgot this step, so did I, so will you probably. Then redo the 4 screws on back, 2 each top and bottom, 3 each side and put the 2 brackets back on.....all ready to go and not that tricky really.

      Onto the android unit. You need to remove the top screen because there is a daughterboard to put inside the case. Each side vent pops out from clips; start at the bottom and carefully remove upwards (use a trim remover tool to avoid breaking anything). Then the lower screen and controls come out, 4 screws, a couple of clips (including 3 flimsy ones at the top) and 3 plugs on the rear. Then the upper screen, 4 screws and a bunch of plugs and she is out. From there, remove the mounting brackets (2 screws each), 4 screws on the rear, 2 screws top and bottom and 3 screws holding in the small plates on each side. When you remove the back cover (tight fit), watch out for the power cable for the fan, I removed it so I could put the back aside. The mainboard is held in by 1 screw in the middle, 1 aerial at the top and 3 ribbon cables. If you've ever done any laptop stuff the ribbon cables are OK to work with, just pop up the retainer and they slide out. If you are not familiar just grab a 12 year old from an iphone factory, they will know how it works The case should now look like this:

      Switching the console was tricky. First there were 6 screws to remove, and also the little adapter loom and its screws had to come out. Also don't forget to remove the 2 screws holding the central locking receiver. Then there are 4 clips on either side....these were very tight in this case and needed careful persuading with a long flat screw driver....some force required but not enough to break them...this was probably the fiddliest part of the whole job. In my case I needed both the wiring loom and the central locking receiver module to swap across to the new one. That was it for the console, so "assembly is the reverse of disassembly"
