Atessa Playing Up?!?

Hey guys I have a R32 GTS4.

Recently the ATESSA is playing up and ive already checked the fluid levels. When i'm cruising at say 100 down the freeway it's trying to transfer torque to the front wheels when it should all obviously be going to the back. You can feel the transfer case put some up at the front then stop and try again, meanwhile my front torque guage is getting anywhere up to 15kg's. I'm wondering what the hell is wrong with it? I have been told briefly about the attessa computer flashin up codes to let you know whats wrong, however i'm not hugely familliar with this? Also that if the ATTESSA senses it's stuffing up it is supposed to divert all power to the rear wheels as it's a safety issue and buggers your transfer case, but mine isn't doing that when ive had the fuse in. I think a possible problem is the G-meter is playing up, but i just wanted to know if anyone has experienced this at all in their R32 GTR/GTS4? If so any help would be VERY much appreciated!

Cheers guys :D

^ Had these exact symptoms when i had new ever-so-slightly larger rolling diameter tyres put on the back.

The attessa fault codes are easy to read, the led on the unit in the boot flashes a certain amount of times for the fault code(s) with a pause in between each fault. Just search on here for the code listing.

make sure all the wheels/tyres are exactly the same size.I had this problem in a GTS4 I had.It would pick up a small vibration and torque guage would start flickering slightly.Standard wheels back on problem solved

Hey cheers guys!

Yeah a few weeks ago I had my fronts changed (same tyres as before) but obviously they have more tread than the ones at the rear. And considering my rears are now due for a change, it seems a new set on the back should resolve the problem. I'l change them out the end of this week and see what happens. Still has been fun driving around in RWD for a few weeks, haha.

Take it easy

      I would just put EBC back on the "I would not use their stuff" pile and move on.

      Can I suggest you try EBC directly again and link them to as many competitor catalogues as you can to show their listing is incorrect, eg https://dba.com.au/product/front-4000-series-hd-brake-rotor-dba42304/ If you have access to an R33 GTST VIN and your VIN, you could also use a Nissan Parts lookup like Amayama to show them the part number is different between 33 GTST and 34 GTT which may get their attention

      So i got reply from EBC and they just this site where you can clearly see those 296mm fronts on R34 GTT. I send them photos and "quotes" that 296mm are not for 34 GTT and they are too small. But it will be very hard to return them cuz nobody here knows 100% and they just copy those EBC catalogue :-D https://ebcbrakesdirect.com/automotive/nissan/skyline-r34

      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.
