While I was at it thought it would be good to source a new coil pack harness as the other one looked rather brittle and stiff also got some brand new NGK platinum spark plugs BCPR7ES and I gapped t

id be re doing the harness.

solder my man. get that iron out. i cannot stand wiring like that even if i cant see it.

think you are right Paul

Also think that a new harness is going to have to be on order

Burn more money burn :rant:

I'd try source a new male plug w/ pins from Haltech or wherever. Cut it back and start again. Poor connections raise resistance, altering sensor readings from true. If you didn't want to solder, maybe source some weatherproof connectors like deutsch. We use them at work and installed correctly, can outlive the life of the machine in some pretty harsh environments. We prefer if possible to plug/receptacle as solder joins can become brittle and hard over time, and if there is any vibration can crack.

I prefer having an entire new harness.

However, I have just done a some quick research and found this from Haltech

the very last post got my attention

The attessa error code is still 29 even after this new tps has been installed

I wonder if something has reset itself

Got to love people butchering up the harnesses like that. Mine was the same as yours so when I switched from PowerFC to the Link I replaced the harness for peace of mind - was good that I did as I also found that the front left wheel sensor plug had melted and become disconnected :/

Do you remember changing / touching anything for the light to come on or did it just appear one day?

all I did man was remove the oil catch can from the engine bay and give it a good clean out

there was a ground wire that I thought was in the way so I started to unscrew it (sits directly below where the oil catch can sits behind / next to the battery hook) but I couldn't take it off so I just tried to tighten again (but still seemed a bit loose, wonder if there is nut underneath)

after I had cleaned the oil catch can I reinstalled with the breathers attached and went for drive

got to the traffic lights at the end of my street (600-700m or so) and before I could even cross the 4WD light came on.

Make sure your battery and earths are good..

That's given me heaps of troubles before with my attessa

Yeah. I will check it over.

Could be so many possibilities.

What an absolute PITA.

But I guess it gives me the chance to find electrical issues that need to be resolved so probably a good thing.

Phewww.........So I fixed my 4WD issue :banana: :banana: :banana: :banana:

It was what GTR_JOEY said and was a loose / dirty ground wire which also grounded the battery wire in front of that silly catch can.

I gave it a good clean and replaced the screw with a new one as the old one was totally stripped of its thread (not sure how :dry: )

then couldnt help myself and take the car for a spin - all four wheels blazing like they should be.

Thanks Joe again for the tip.

and to all that get 4WD errors - CHECK YOUR EARTHS!

      R34 GTR Speedo Drive , sensor type ?

      By Butters · Posted

      Working through possible solutions of converting my mechanical speedo.    Anyone know what type of speedo sensor the factory r34 gtr getrag has ? what the output is ? I assume its not a VSS and more a voltage like earlier speedo sensors ? Can an ECU read it ?

      I can get more photos of it here soon and I plan to make a thread detailing the process. I received the car this way and it sorely needs refinishing. That is probably the most appealing photo of it. Up close it is fading, cracked, and needs to be re-glued. Depending on their condition I'm on the fence between refinishing or making a new set.  Another angle hiding the pimples and razor pumps

      Can you mount the ATTESA pump in other locations?

      By AnimalGarage · Posted

      According to this thread the RS4V with build plate RC40 comes with the R200 diff @ 4.083 ratio as well (mine has said RC40 denotation). We may need to check if the axle stubs are the same pattern as well. The auto subframes have longer axles. However I think yours being a later Series 2 as well, we should have the same bolt pattern for the diff stubs. Unless your upgraded rear also has upgraded axles. Either way, I would not be opposed to pulling the covers to check so I can inspect that  fancy rear core  Also I don't have HICAS. I don't believe that should change things but I hope the people here with heaps more experience than me can correct me if I'm wrong   Let me know if you want to attempt to make this work and I can get some pictures of mine from under the car.

      R34 25GT Engine Light 21

      It's not that straightforward. For example I have had this code because my ignitor/power transistor wires were unplugged. It knows something is wrong but has no idea what it means. If you want to actually diagnose this I recommend following the service manual flowchart for code 21. Ohm out the harness, coilpacks, inspect the ECU, etc. And again, it's entirely possible for there to be no problem at all but if you're running a different coilpack it'll trigger the code because it doesn't like what it sees.
