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.

      I gotta pull you up on this. It's driving me crazy. A shutter is something that closes, like over a window or in a cmera. The word you want is shudder. That LSD is clearly f**ked. Take it to a diff shop and get it disassembled and examined by an expert. YOu might have plates welded together or something equally crazy.

      S1 rb25/s14 starting problem

      By GTSBoy · Posted

      Check the Nistune doco. There are a few assumptions being made here that might not be valid. I will list the things that occur to me: Base map. Base map for what? Base map for Z32? Then the cranking pulse width is probably wrong for an RB25. The extra 500cc of capacity might well be enough to prevent it from catching. Base map for RB25? I don't think you can load one of those into a Z32. You have to just make the settings correct for an RB25 in the Z32 base map. That is either K or the TIM to get the pulsewidth right. Loom. You bought a loom for an RB. And you plugged it into a Z32 ECU. Did you make sure that any iwre differences were swapped. From memory, there's at least a couple. And as per the others, I would suggest making sure that the fuel pressure is correct while cranking and that the injectors are actually flowing as expected. They really must come out and go on the bench, unless you do find that you have messed up as per above points. I would also suggest watching in Nistune to make sure that everything is reading correctly. That the correct binary flags are raised at the right time (like the crank signal), that there's no stupid values in K or TIM. That you have not got mismatched firmware for the ECU and/or a wrong image loaded.
