Ive just bought an R34, and the traction control light on the dashboard doesnt come on at all. Even when you operate the switch on the dashboard ( in front of your left knee).

I suppose the traction control prevents 1 wheel slipping more than the other in slippery conditions, and if you dont want the feature you turn it off via the switch on the dashboard, and a light comes on on the instrument panel.............So where can I start to repair this feature?

Im starting to think that a workshop manual is a necessity with this model, but at $650.00, it is a bit steep.

I have just bought a 1999 GTT ER34 as well ... waiting for Compliance to become available again before I import. But I have a translated Japanese manual I bought from www.importdrive.com.au ... it was about $50 I think... for those interested.

As far as I can tell from the book cars fitted with TCS have a button on the left hand side just under the steering wheel to turn the feature on or off (above your left knee as described already).

Also when you have the TCS on No light should be on in the dash. When you turn the system off there will however be a light confirming TCS OFF .... as far as I can tell TCS will do its job in the background when required.

Accrording to the manual when TCS actually kicks in under heavy acceleration the Slip light will flash indicating that the car may slip .... I suppose thats the only evidence of the TCS operating you'll see in the instrument panel.

One good way to check to see if its the globe or the light thats faulty is to check it when you are turning the car on ... as the car is turned on BOTH the TCS OFF light as well as the SLIP light should come on in the dash, after the car has started and if the system is working properly both lights should then go off. If either the TCS OFF light or SLIP light stay on afer starting the car this indictaes a fault in the system ... thats when you need to get it repaired.

Hope that helps

YES, that is exactly what happens!

Btw TCS works by reducing engine power when it detects wheelspin to the driving wheels - in theory it should prevent you from 'burning out' your tyres too but in the wet it can still spin - I have tried it at heathcote whilst doing some 1/4 mile runs...

Sorry to dig up this old post but I've just got a GT-T and noticed that with the TCS on sometimes under hard acceleration the car seems to shudder when accelerating. It starts to accelerate hard then drops revs then goes again then drops revs etc. Doesn't do it with TCS off. I imagine this is just TCS functioning correctly by limiting revs when wheelspin is detected? In this case it will be switched off from now on unless its wet.

Yeah, you got it correct NJR 34GTT, it only drop the rev to prevent the power going from the engine to the wheel so the computer disconnect the power to the wheel due to wheel spin.

So remember to turn off your TCS while you are racing :cheers:. In wet day it's very useful though hehehe.

About boost cut/fuel cut issue I can't really answer that :)

That's from me

Hmmm.... After reading a few other threads I have realised this could also be boost/fuel cut? Since its running 13psi which is supposedly very high for a 34 I suspect this is more likely the issue?

I run mine at 1 bar but I had to fit a fuel defender to be able to do that.Other wise car misses and starves of fuel.

It is a wonder your car is not missing and farting running at 13 lb or do you have a fuel defender fitted.

No running issues at all.

Basic mods on the engine, pretty sure it is the tcs.

as it is happening at quite low revs ~3000-3500rpm as opposed to the higher rpms usually experienced with boost/fuel cut.

As for the fuel defender I am not 100% sure but it was tuned to run as it is with the boost level and has been running it quite happily for over a year now.

      Did this end up working? Did you take some pictures?

      And finally, the front lower mount. It was doubly weird. Firstly, the lower mount is held in with a bracket that has 3 bolts (it also acts as the steering lock stop), and then a nut on the shock lower mount itself. So, remove the 3x 14mm head bolts , then the 17mm nut that holds the shock in. From there, you can't actually remove the shock from the lower mount bolt (took me a while to work that out....) Sadly I don't have a pic of the other side, but the swaybar mounts to the same bolt that holds the shock in. You need to push that swaybar mount/bolt back so the shock can be pulled out past the lower control arm.  In this pic you can see the bolt partly pushed back, but it had to go further than that to release the shock. Once the shock is out, putting the new one in is "reverse of disassembly". Put the top of the shock through at least one hole and put a nut on loosely to hold it in place. Put the lower end in place and push the swaybar mount / shock bolt back in place, then loosely attach the other 2 top nuts. Bolt the bracket back in place with the 14mm head bolts and finally put the nut onto the lower bolt. Done....you have new suspension on your v37!

      And now to the front.  No pics of the 3 nuts holding the front struts on, they are easy to spot. Undo 2 and leave the closest one on loosely. Underneath we have to deal with the wiring again, but this time its worse because the plug is behind the guard liner. You'll have to decide how much of the guard liner to remove, I undid the lower liner's top, inside and lower clips, but didn't pull it full off the guard. Same issue undoing the plug as at the rear, you need to firmly push the release clip from below while equally firmly gripping the plug body and pulling it out of  the socket. I used my fancy electrical disconnect pliers to get in there There is also one clip for the wiring, unlike at the rear I could not get behind it so just had to lever it up and out.....not in great condition to re-use in future.

      Onto the rear lower shock mount. It's worth starting with a decent degrease to remove 10+ years of road grime, and perhaps also spray a penetrating oil on the shock lower nut. Don't forget to include the shock wiring and plug in the clean.... Deal with the wiring first; you need to release 2 clips where the wiring goes into the bracket (use long nose pliers behind the bracket to compress the clip so you can reuse it), and the rubber mount slides out, then release the plug.  I found it very hard to unplug, from underneath you can compress the tab with a screwdriver or similar, and gently but firmly pull the plug out of the socket (regular pliers may help but don't put too much pressure on the plastic. The lower mount is straightforward, 17mm nut and you can pull the shock out. As I wasn't putting a standard shock back in, I gave the car side wiring socket a generous gob of dialectric grease to keep crap out in the future. Putting the new shock in is straightforward, feed it into at least 1 of the bolt holes at the top and reach around to put a nut on it to hold it up. Then put on the other 2 top nuts loosely and put the shock onto the lower mounting bolt (you may need to lift the hub a little if the new shock is shorter). Tighten the lower nut and 3 upper nuts and you are done. In my case the BC Racing shocks came assembled for the fronts, but the rears needed to re-use the factory strut tops. For that you need spring compressors to take the pressure off the top nut (they are compressed enough when the spring can move between the top and bottom spring seats. Then a 17mm ring spanner to undo the nut while using an 8mm open spanner to stop the shaft turning (or, if you are really lucky you might get it off with a rattle gun).

      You will now be able to lift the parcel shelf trim enough to get to the shock cover bolts; if you need to full remove the parcel shelf trim for some reason you also remove the escutcheons around the rear seat release and you will have to unplug the high stop light wiring from the boot. Next up is removal of the bracket; 6 nuts and a bolt Good news, you've finally got to the strut top! Remove the dust cover and the 3 shock mount nuts (perhaps leave 1 on lightly for now....) Same on the other side, but easier now you've done it all before
