Hi I think I have the same problem, did this ever get fixed or has anyone else had this problem?

[Jas23]

So I was researching this issue and came across this thread. Looks like I have the same issue. On cold starts the 4WD system always works fine but sometimes on hot starts the 4WD error light comes up on the dash and the car is in permanent 2WD mode.

Had a look and it always seems to be error code 18.

Joey did you ever solve your problem mate? It's just painful with no 4WD the car is way to tail happy. I'll start testing this weekend hopefully but any insight would be appreciated.

Just wondering if you guys resolved this problem?

I have an R32 GTR with error code 18. Tested the circuit as per the workshop manual and it's all good. However 4WD light stays on permanently and attessa pump only primes rarely on startup.

Any input from other people's experiences would be appreciated before I begin to change pressure switches and pumps out of desperation!

Look at the positive terminal on the battery. See if you can replace/improve the links.

Ravi - if you are replying to my comments I have a new battery and new cabling, solid connection. An auto elec also tested the entire Attessa circuit and all powers up fine.

Summary of my issue:

- 4WD and ABS lights stay on constantly

- Attessa computer reporting Error code 18: “ETS pressure switch or circuit fault”

- Auto elec checked all circuits and wiring thoroughly, all is ok

- 4WD pump primes on initial startup but no pressure going through lines to gearbox

- When pump is forced to prime (sending power direct to pressure switch) no fluid is coming to gearbox

Might have to bite the bullet and replace the pump!

Tried replacing the nitrogen canister above the rear diff ? It's 25 yrs old.

And I should add not cheap at around $400

That and then a flush of the fluid to be thorough

Made me a happy camper.

Haven't tried, but makes complete sense to do so. Any advice on where I can get a new nitrogen canister?

Thanks for the response!

Call John at Trojan motorsports in Canberra. He could either supply or put you in touch with his supplier. 4wd issue gonski. No light, no error code. I'm chuffed

I didn't have any errors, but i replaced my canister and it totally changed the behaviour of the system during bleeding.

I got mine from rhdjapan (few months ago) it was about $280. My pump was starting to make funny noises from running all the time, wish I had changed it ages ago

I've just ordered a new Attessa accumulator from RHD for $320 delivered.

Problem is that I really don't know if I have a faulty pump or empty accumulator

Very late reply, I did end up solving the issue mate, what the issue actually was, stuffed if I can remember haha think it may have been battery related

I've actually got another fault now so will be interesting to see what that one is as well

Did this fix it mate?

Yes my 4WD is working like a dream now. Fitted the new nitrogen canister and bought a digital G-sensor to replace the old original sensor... Car hooks up all four wheels almost instantly on the track! No tail happy over steering with delayed torque split anymore.

Next I will rebuild the transfer case to ensure best possible mechanical engagement.

Everyone who owns a 32 GTR should be replacing the Nitrogen Canister & G sensor

Transfer case will put the icing on the cake

Totally agree. Only wish I knew about it earlier!

[GTR_JOEY]

Sweet, where did you get it from and how much?
