R33 Attesa Troubleshooting

When putting my R33 gts4 on the dyno I've discovered that the 4WD is not working.  It might have actually been broken for awhile, it would explain my poor 60ft times when I was drag racing last year (a month before I had the engine rebuilt).  However in general driving I've only ever seen 4WD become active twice in the 7 years I've owned the car - I don't drive it hard on the street.  That said the 4WD light wasn't on and I know it worked because when I had an ABS sensor go it did light up.  I've now switched out my gtr ecu for a Link G4+ and a dash2pro so I don't know how to fault find on the attesa system anymore - does anyone have any ideas?

Fault finding on the Attessa is done on the Attessa  ECU where there is alleged to be a blinking light (haven't done it myself). If you haven't already you need to run a wire from the TPS to the Atessa ECU when you fit a Link. Have you checked the reservoir level? Tried bleeding it (one nipple at the back of the gearbox another above the diff)?

GTS-4 doesn't have an indicator like the GTR sadly.  

 

I have check fluid levels and they are fine.  I'll try bleeding the system.  Attesa to TPS has been done.  I'll try and find the ecu and see if there is a blinking light on it.

      r34's love to squeal

      just an update to this, poor man pays twice  Tried sanding down the pulleys but it didnt do the trick. Chucked another second hand alternator in the na car which I got for free off my mate and its fixed the squelling. Must have been unlucky with the bearings.    As for my turbo car, I managed to pick up a cwc rb alternator conversion bracket + LS alternator for 250 off marketplace, looked to be in really good nick. Installed it , started the car and its not charging the battery.... ( Im not good with auto elec stuff so im not sure if this was all I needed to do but I verified such by using a multimeter on the battery when the engine was running and I was only getting 12.2v )   I had to modify the earth strap for the new LS alternator , factory earth strap was a 10mm bolt which did not fit the bolt on the LS alternator which was double the size so I cut it off , went to repco bought some ring terminals that fit, crimped it onto the old earth strap and bolted it up to the alternator , started the car and same issue. Ran like shit and was reading 12.2 at the battery.  For a "plug and play" advertised kit thats not very plug and play but alas.  My question is , am I missing something ? Ive been reading that some people recommend upgrading the stock 80 amp alternator fuse to a 140 amp but I dont see how that would stop the alternator charging especially at idle not under load.  Regardless ive pulled it out and am going to get it bench tested by an auto elec tomorrow but it would be handy to know if ive missed something silly or have done something wrong.

      My wild guess is that you have popped off an intake pipe....check all of the hoses between the turbo and the throttle for splits or loose clamps.

      To provide more specific help, more information is needed. What Android screen? What is its wiring diagram? Does the car's wiring have power at any required BAT and ACC wires, and is the loom's earth good?

      So, now all you need to do is connect the 2 or 3x 12v feeds into the unit to permanent 12v, ACC 12V and IGN 12V that you can find in the spot behind the stereo, and the earth, and then it will switch on with the car.
