Hey guys I've just bought myself a 98 R34 GTT. Not I found a few little problems with the car but nothing major. The one thing that's got me is the TCS system doesn't seem to work at all???

I've checked the boot for and mods to the ECU , checked the plug and it's plugged in. I'm just lost at what next. The car breaks traction all the time and I have no slip light at all on the dash board. Not even with ign on

All the plugs are plugged up to the butterfly near the TB.

Please any ideas would be greatly appreciated.

Cheers

The traction control system sucks hard, and just slams the throttle shut. Disabling it is a smart thing to do.

Making it work again is a waste of time.

Get better tyres, drive better.

How much power is it making?

Please check your ECU fault codes and report back. Instructions here, scroll down for a pic of which pins to short: http://www.sau.com.au/forums/topic/266512-reading-nissan-fault-codes-ecu-fault-codes-how-read-them/

I'm currently getting Code 17: ABS-TCS C/U Signal. My TCS never worked since the manual conversion but the ABS is fine.

TCS and SLIP lights are on in the dash too, along with A/T and HICAS because they no longer exist...

Should also state that all it really does is put a 2nd throttle to 60% max throttle. I was able to break traction pretty easily with stock power with the traction control on

Fresh avatar Greg? And yes you're right it's not the most sophisticated system is it...

No. Fault codes are read from the dash light. I don't know what light they use in a 34 - it could be a dedicated CEL. I have my Neo in an R32 so I have the cat light as the CEL.

The best way to read the codes is to use a Consult scanner plugged into the Consult port. More to the point.....the best way to read codes on any of the control units in the car is through the Consult port. If you have a buggered sensor (say the steering angle sensor) then you cannot execute the routine required to put the HICAS CU into diagnostic mode. So you can't find out that you've got a buggered sensor. See the fault in Nissan's logic with the silly dances you have to do to enter diag modes? Scanners cut right through that crap.

Resetting the ECU is a simple case of leaving it without power for a while.

A lot of people actually remove dashbulbs to mask hardware faults that bring up the lights. ABS/TCS, being as optional as they are, would be the biggest candidates.

See my previous post above for how to read ecu codes without consult cable. No dash lights sounds sus, definite check the full list of codes

Yeah I know sounds suss right. I gotta a feeling sum1 stuck a low k cluster in there and took a few bulbs out

      R34 GTR Seats / No longer reclining

      By bilbo117 · Posted

      Hi all, Long time since I've posted here. Looking for some advice on what I can remove to further identify the cause of my issues.  I can move the passenger seat forward and back but the knob used to adjust the seat angle is pretty much free spinning, there's very little resistance.  Removing the side cover I can see that the chain is intact but the shaft for the adjustment spins without the gear attached to it moving.  What's my next step for disassembly here? Is this a common fault? Just being a little cautious as I didn't want to start removing bolts for a spring to fly out or something equally as stupid.  Cheers

      Those above shitboxes, mediocre and above usually have a turbo strapped to them, hence the slightly higher octane is required.

      I mean, I got two VASS engineers to refuse to cert my own coilovers stating those very laws. Appendix B makes it pretty clear what it considers 'Variable Suspension' to be. In my lived experience they can't certify something that isn't actually in the list as something that requires certification. In the VASS engineering checklist they have to complete (LS3/NCOP11) and sign on there is nothing there. All the references inside NCOP11 state that if it's variable by the driver that height needs to maintain 100mm while the car is in motion. It states the car is lowered lowering blocks and other types of things are acceptable. Dialling out a shock is about as 'user adjustable' as changing any other suspension component lol. I wanted to have it signed off to dissuade HWP and RWC testers to state the suspension is legal to avoid having this discussion with them. The real problem is that Police and RWC/Pink/Blue slip people will say it needs engineering, and the engineers will state it doesn't need engineering. It is hugely irritating when aforementioned people get all "i know the rules mate feck off" when they don't, and the actual engineers are pleasant as all hell and do know the rules. Cars failing RWC for things that aren't listed in the RWC requirements is another thing here entirely!

      Best place to order Authetic R32 Parts in Japan

      By GTSBoy · Posted

      I don't. I mean, mine's not a GTR, but it is a 32 with a lot of GTR stuff on it. But regardless, I typically buy from local suppliers. Getting stuff from Japan is seldom worth the pain. Buying from RHDJapan usually ends up in the final total of your basket being about double what you thought it would be, after all the bullshit fees and such are added on.
