R34 Tcs Not Functioning

[Ohthatsnasty]

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.

Not relying on the TCS, I made a mistake and i admit that, I've done a defensive course but need to do one of the advanced courses.

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

[Ben C34]

The gasket has no impact on the tps.

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.

99% sure it's the stepper motor on the TCS that controls the butterfly valve in the throttle body. I replaced my one and fixed the problem instantly.
