Abs Removal Causing Attesa Faults?

My car seems to have had the abs removed (no more abs unit with the metal brake lines coming out of it in the top right hand side of the engine bay), and is showing a 4WD fault light on the dash. After consulting the Nissan fault codes for the ATTESA ecu, it came back with:

Fault 8 ABS actuator motor, motor relay, or circuit

Fault 9 ABS actuator relay or circuit

Fault 18 ETS pressure switch or circuit

Apart from fault 18 with the pressure switch, could the other two faults that relate to the ABS (which has been removed) be causing the 4WD system to shut down?

The front wheels dont seem to have any drive, and the torque split gauge shows this as well...

was your car always like this?

ok... well what happens is... the ATTESSA depends on the ABS sensors to operate... as well as the AWD system.

so when removing the ABS system, you need to trick the ATTESSA by rewiring a few electricals...

and apparently this does the trick.

Hi eeiko. Well I have only had the car for a couple of weeks, so can't be sure how long it's been like this for. I was thinking that tricking the system might be the way to go - any idea how this is done mate?

heya

well someone has done this before...... i think it was someone on this forum years ago

but it may be a bit fiddly with the electricals but should be pretty straight forward...

so how good are you with handy work?

I have experience with fiddly electronics, and work as a sparky so I have some idea :)

I like to tackle most things myself if possible!

there was an article i read on this

and apparently Auto sparkies dont understand how the ATTESSA works

ill have a sticky beak through and ill PM ya with details

its definately not hard to do

Hey thanks mate :P , that would be mucho appreciated! I have been doing research of my own but sometimes with these things it's like looking for a needle in a hay-stack...

I removed ABS from 32 GTR and it made no difference to anything, same with Hicas, just removed all the plugs and everything else worked same as before. Maybe the wheel sensors have been disconnected.

      What brakes on R34 GTT(Europe)

      By GTSBoy · Posted

      The 296mm rotors are the R33 turbo brakes. The 310mm rotors are the R34 turbo brakes. The calipers are nearly the same, but not. They're the same caliper but the R34 caliper has longer legs so that it sits out far enough to go over the rotor. The pads are the same for both. When you say, "I bough tsome EBC"....did you just mean pads? Or rotors? 310mm rotors fit under 17" wheels. There may be some wheels without enough clearance though. I can't fit my fingers between the barrel of my wheel and the "corners" of my R34 calipers, but there is plenty of room behind the spokes. This is on Enkei RPF1. You can fit 324mm rotors inside a 17" wheel, but I'd be willing to bet that it would be close to impossible with the Nissan/Sumitomo caliper (using an adapter, of course), because the Sumitomo caliper is fatter than the Brembo caliper that is supposed to go on the 324mm rotors.

      Hi. Can someone tell me what brakes(and mainly WHERE) can i buy brakes on R34 GTT? I bought some EBC which SHOULD go on my car(i have GT but it has GTT brakes) but it does not fit, Brakes are "too" small(296mm) Are 310mm be good or? I have 17 inch wheel so no "big boys" but for me driving i just need one that fits and i can get here in EU/Czech.

      Hey. Very valuable information about pitwork, I will pay attention when buying any consumable parts 🙏 As for the carpets - I got a handful of information from nengun, from which it appears that indeed the carpets for the driver's side are OEM. They are not able to show me any pictures due to the long chain of different sales entities but after I place the order, as soon as the goods arrive at the nengun warehouse from which they will send the shipment to me they can send me photos and if my purchase differs from OEM I can immediately return it / cancel the purchase. I think I will give it a try 😉. Of course i'll let you know what's what as soon as i get them P.s. I know the topic is not relevant to the thread, but both nengun and amayama have these SICK 😍 trunk room lamps available. Do you know anyone who ordered them? I need to have one in my car
