Tc Failure

Hey guys,

A couple of months ago I bought an r34 gtt. But lately it has developed a new trick.

Within 10 mins of the first drive of the day the tcs off and slip signs come on, as well as the malfunction indicator light. It usually just takes a few stationary restarts to get it back working, but i was just wondering what the cause could be?

I had a look round for similar topics but most people seem to have permanent tc problems, whereas mine is only in the first 10mins of driving and temporary.

Any clues?

Thanks heaps

its getting worse. yesterday the error light came on, tc turned off and the car ran like shite for a while. 2 restarts later and it went back to normal. i guess this is some ecu problem?

It may pay to check if a previous owner has put in a TCS modifier this reverses the switch function (so you have to turn it on not off after you've started the engine) and is hard wired in near the tcs control unit in the boot.

I was going to put one in but decided against it for no particular reason after I'd bought it.

It may have been poorly installed or removed and have damaged the wireing.

Just a thought.

Mine does the exact same thing mate.

It' will slowly get worse, to the point where the lights will only stay off from startup until you put it in gear, then straight on, and stay on.

I've found that occasionally nailing it (wheelspin) can turn 'ON' TRC again (ie, lights 'off'). Rare. I think it's simply a broken wire, possibly transmission tunnel area, as I pulled the carpet up to dry it out*, and the lights went out for a day and a bit, but came back.

I'm certain it's not a broken wheel speed sensor, as ABS still works fine.

The ENG light occasionally (rare) comes on, and gives code 28, I have no idea what that refers to, I simply clear the codes, and it's fine. The first time I got this code was when I tried remote starting it in 'Drive', and the sensors denied start procedure. Other times haven't had a pattern.

If I park facing downhill (only) and it rains heavily, the cabin air intake/front rain gutter area overflows near the driver's A-pillar and leaks into the driver's footwell (*hence \drying the carpet above :blink: ) Is this a common fault?

thanks for the info mate. how do i see the error codes? and does anyone know where a key to the codes is?

lol ill answer my own question for anyone who may have been awaiting an answer:

error codes can be checked using this method

lol, being a newb is a little tiring sometimes. i'm yet to do a search for coilpack problems, but it sounds like that's going to be the problem

cheers

You might want to invest in a console cable, i got mine for $60 off ebay. Invaluble tool for getting stats/error codes and running diagnostics on all older pre OBD-II nissans.

i will do that sometime in the near-ish future, but atm slightly conservative on the mulahs.

just wondering tho, why would coilpacks bailing cause the tc to fail?

      Quieter performance exhausts (or muffler add-on options)

      By f00stx · Posted

      So, I've had my V36 for about a month now and have already copped an "excessive exhaust noise" notification from QLD TMR, reported by someone in my local area. It's a twin as per the original, and can have a bit of a throaty note to it when idling cold 😄 and if I do get up it a bit, it can be noisy, but it did pass a roadworthy inspection before sale, so.... ... but in the interest of being a good neighbour, I do want to quieten it down a bit. Is anyone here running a quiet aftermarket cat-back on their V36 or 370Z? And the big, bold question: does an aftermarket cat-back really make much of a performance difference on these cars?

      The wiring diagram for the R33 RB25 is freely available, and is essentially the same same as most other RBs (just with differences as to which pin # does which job). To get the ECU to power up, you just need to provide power to the ECCS relay, and have the other power feeds that come in from the top left of the wiring diagram (wrt the ECU) that give perma power to the fuel pump relay, the ECU itself, etc etc, all connected. When you put power on all these it will just come to life. It's pretty clear from the diagram what needs to happen. Just follow the lines from the 12V + supply stuff in the top left over towards the ECU. I've even posted snips of such diagrams (not for vanilla 25, I think for Neo and 26) to various threads here in the last few months, talking about what it takes to get the fuel pump and FPCM up and going. Search these up and they will help get you started on doing the same with the vanilla 25 diagram. Hell, for all I know, I've done the same with that one in years past and have forgotten.

      Yep...so unless someone posts up the answer you will need to probe from the ECU connector to the dash plug with a multi meter in continuity mode to trace the wires.  Note the ECU has multiple - and + (and across different key settings - Battery, IGN and Start) and most likely the power is fed from the connector(s) that is normally near the left hand headlight.

      Thanks Duncan, I am actually just trying to get the Rb turning and running with the RB25DET S2 original loom itself  I am just trying to get it going outside the body and not thinking about the S15 or trying to match anything to the S15 loom at all I am only trying to see if anyone has done this and what pin they found to be the ignition trigger and ECU+/- on the dash connector, that's about it. Thanks

      M35 VQ25DET starter motor

      By iain_ST44GA · Posted

      Hi Guys, Does anyone know any aftermarket part numbers for a starter motor to suit the VQ25DET? I can find lots of alternative part number for the VQ35DE, which I assume would fit, but there is a lot of conflicting information out there. Thanks..
