I bought my r34 gt-t 5 months ago, second day i owned it i spun it out into a couple (5) plastic posts and luckily only did panel damage. Anyway after that i wondered why tcs hadn't kicked in, the car just lost traction and away i went. I checked the fuses and surprise surprise Mr Tokyo Drift (previous jap owner) had pulled the tcs fuse and the dodgy as hell importer just pulled the dash globe for the tcs warning light. i replaced the fuse and globe and all was sweet. fast forward a month ago i pull my throttle body off so i can replace the rocker cover gaskets as it is leaking a fair bit of oil past them, put everything back in and know my tcs no longer works and the tcs light is always on. Does anyone know what i did wrong?

TCS module is the one in front of the throttle body (R34 has 2 throttle bodies, the first one the air flows through is electronically actuated by TCS the second one is mechanically activated by the accelerator pedal.

TCS module has two plugs, one on the "front" of the TCS module and one on the "back" of the TCS module (back means nearest the firewall). You need both. The rear plug on mine has loose pins that slip out if you move the plug so double check your connections.

Why do you care? I always turn it off, not mashing the throttle is easily achievable.

The way the tcs cuts in is so harsh its ridiculous.

Anyway, check you have all the plugs on the throttle bidy and tcs throttle body plugged in correctly.

Was told the same by donovan from forced motorworx today, Will have to check the wiring and the pins for damage/looseness(is that even a word?)

Also the car has sustained $1500 in panel damage with the tcs off so i would rather it being on.

There are 3 things you need to know when you start driving a Skyline (I'm guessing nobody told you these very important rules):

1) Don't accelerate around corners

2) Don't accelerate around corners

3) Don't accelerate around corners

Don't blame the lack of TCS. Blame your right foot. Second day of owning a new car and "relying" on TCS is foolhardy. That's the nicest way I could possibly put it.

Also, do an advanced driver training day. Can't recommend them highly enough.

When i changed my rocker cover seals, the throttle body had to be removed. If you dont use the right gasket or if theres a leak in between when reinstalling, your tps will throw an error and your car will run like crap. Your tcs light will remain on too.

Hope this helps.

I ordered a new Gasket from taarks (genuine nissan metal gasket) when i did mine and hasnt leaked since. The stock paper gaskets are so brittle and shouldnt really be reused imo

Especially since i am running a new stock nissan gasket, Anyone have any ideas? It's is still showing the light and tcs is most definitely not on. pulled the throttle body again and cleaned it again, cleaned the contacts and checked wiring all ok.

    • Well, my new WMI system took much longer to finalize. I actually missed my dyno appointment last Friday and lost my 150$ deposit. I'll be going back in the next week or two.  To sum it up. I only kept the AEM tank from my old setup. I replaced the AEM pump with a higher flow/pressure ProMeth 30GPH pump. I also swapped over to a 6AN low pressure feed line to the pump from the tank. There's also a pressure switch you cannot see on the pump high pressure line.    This is feeding 6x 200CC direct port nozzles and 1x 500CC Pre Throttle body nozzle. All fittings are Swagelok, because well why not. I also have a 300PSI pressure sensor up front.    I now have my Haltech ECU controlling everything. I start my pump with a basic relay at 5PSI and deadhead it. I then PWM a 3000CC methanol Injector to control flow starting around 10psi. The pressure switch in the trunk, along with my tank level are safeties before I ever get to 10PSI, and then I use my pressure sensor upfront as a secondary safety to cut the WMI and corrections in case the injector blocks or a line ruptures.  Wish me luck on the dyno!    
    • So, I'm back with bad news. There's no jack long enough on this planet that will reach the front subframe. If by some chance there is, it would weigh 200lb's.  I purchased a long reach jack... The damn thing weighted 120lb's and was massive. Didn't even come close, was still short at least a foot. It was a pain, but I brought it back. Next I decided HA! No problem, I'll get an Extra long reach jack. Well, I couldn't lift the box... It must have weighed 160LB's and luckily there was an open box in store. I took measurement and was still nowhere close.  Sadly I've lost hope and have accepted defeat. 
    • Thanks for that tip, niZmO_Man. I think the battery is OK. It's quite a new one, but I'll check. Last time I needed a new battery, everything electronic was fine, except that there wasn't enough current to turn over the starter. I decided to order one of the partial AV system translation CDs from Car Audio Workshop in NZ. That might have some effect, or help me diagnose the date problem. 🤞
    • I suppose it was relatively stock too, the JZ motor handle most mods thrown at them without even breaking a sweat 
    • I saw your intro update, are you sure you've actually had a starter motor failure? You mention it could be the alarm causing it. I'm assuming you've got a no start issue, but what are the exact symptoms, as there could be a few reasons it has stopped wanting to start.
