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.

    • Which solenoid? Why was it changed? Again, why was this done? ...well, these wear..but ultimately, why was it changed? Did you reset the idle voltage level after fitment? I'm just a tad confused ~ the flash code doesn't allude to these items being faulty, so in my mind the only reason to change these things, would be some drive-ability issue....and if that's the case, what was the problem? Those questions aside, check if the dropping resistor is OK ...should be 11~14 ohms (TCU doesn't throw a flash code for this) ~ also, these TCU designs have full time power (to keep fault code RAM alive), and I think that'll throw a logic code (as opposed to the 10 hardware codes), if that power is missing (or the ram has gone bad in the TCU, which you can check..but that's another story here perhaps).
    • Question for people who "know stuff" I am looking at doing the new intake like the one in the picture (the pictured is designed for the OEM TB and intake plenum), this design has the filter behind the front bar, but, the filter sits where the OEM duct heads into the front bar, and the standard aperture when the OEM ducting is removed allows the filter to pulled back out of the front bar into the engine bay for servicing, a simple blanking plate is used to seal the aperture behind the filter This will require a 45° silicone hose from the TB, like the alloy pipe that is currently there, to another 45° silicone hose to get a straight run to the aperture in the front bar Question: how will it effect the tune if I move the MAF about 100-150mm forward, the red is around where my MAF is currently, and the green would be where it would end up Like this This is the hole the filter goes through  Ends up like this LOL..Cheers    
    • Despite the level up question, actually I do know what that is....it is a pressure sender wire.  So check out around the oil filter for an oil pressure sender, or maybe fuel pressure near the filter or on the engine. Possibly but less likely coolant pressure sensor because they tend to be combined temp/pressure senders if you have one. Could also be brake pressure (in a brake line somewhere pre ABS) but maybe I'm the only one that has that on a skyline.
    • Pull codes via the self-diagnosis procedure. As far as I can tell this is just a sign of transmission issues but not a code unto itself.
    • Hi All, putting the engine back together and everything is perfect except have this plug left over.. any ideas what it is for and where it goes? Is on cold side under the intake plenum *note not a stock plug, as everything has been modified Cheers
