as of yesterday driving to work randomly the engine light, tcs and slip lights all came on, wasn't driving fast or hard

when i got to the next set of lights, i turned the car off and then on and the engine light stayed off but the other 2 came back on

so i turned the car off and on again and they stayed off until this afternoon when i started the car at work and it happend a couple of times on the way home

when it happens i always have to turn the car off once and the engine light turns off and then again to get the TCS light and slip light to turn off

this has only happened since i did the plugs and oil on the weekend, i only picked the car up the weekend before and it didn't do that during last week

reading other threads i don't think this is unique to my car but i can't seem to get a straight answer from other threads

Mine does the exact same thing.

TCS and Slip still work, but the lights Stay on,

Turn the car on and about 2 minutes into driving they turn on.

My guess was the different sized rims/tyres is affecting the Computer with slip?

Could be many things. mine did the same a while back. replaced my coil packs & it was still doing it.

Mine was dying everytime those lights came on. annoying...

I took it to auto electricians & the codes came up as the afm. it was faulty...

Hey guys I just got my r34 GTT 2000 model, its got an exhaust, pod filter and BOV, the tcs off light is on and the slip light, constantly, the car doesn't run rough or missfire although a pop here and there randomly doesn't seem as though its backfire just a pop, what could this be? Any help will be greatly appreciated, thanks.

update to this, i finally got around to looking at this on the weekend, just loosened the coil packs off and did them up again and made sure the plugs for the loom were all in properly.

the car has never run better, revs a lot nicer and more responsive no more backfiring which was horrendous after i bought the car and got better after i changed the plugs but now gone completely so something must have not been plugged in properly

that miss still happens sometimes though, so i'm going to changed my plugs to a 0.8mm plug as i changed the plugs to 1.1mm BCP6E, and i've only had this issue since i changed plugs

other than that it must be a coilpack, but it just doesn't feel like a coil pack because it doesn't happen on boost like your typical f**ked coilpack, it usually happens sometimes when i first start the car in the morning or when i'm just cruising at 60km/h and goes away generally if i give it some revs

hey guys I did the test and it came up as fault number 17 abs-tcs control unit circuit RB25DET, and in the description it says open throttle body harness? and abs-tcs control unit detects malfunction?, what could that be? what do I need to change? thanks.

      R34 GTR Speedo Drive , sensor type ?

      By Butters · Posted

      Working through possible solutions of converting my mechanical speedo.    Anyone know what type of speedo sensor the factory r34 gtr getrag has ? what the output is ? I assume its not a VSS and more a voltage like earlier speedo sensors ? Can an ECU read it ?

      I can get more photos of it here soon and I plan to make a thread detailing the process. I received the car this way and it sorely needs refinishing. That is probably the most appealing photo of it. Up close it is fading, cracked, and needs to be re-glued. Depending on their condition I'm on the fence between refinishing or making a new set.  Another angle hiding the pimples and razor pumps

      Can you mount the ATTESA pump in other locations?

      According to this thread the RS4V with build plate RC40 comes with the R200 diff @ 4.083 ratio as well (mine has said RC40 denotation). We may need to check if the axle stubs are the same pattern as well. The auto subframes have longer axles. However I think yours being a later Series 2 as well, we should have the same bolt pattern for the diff stubs. Unless your upgraded rear also has upgraded axles. Either way, I would not be opposed to pulling the covers to check so I can inspect that  fancy rear core  Also I don't have HICAS. I don't believe that should change things but I hope the people here with heaps more experience than me can correct me if I'm wrong   Let me know if you want to attempt to make this work and I can get some pictures of mine from under the car.

      It's not that straightforward. For example I have had this code because my ignitor/power transistor wires were unplugged. It knows something is wrong but has no idea what it means. If you want to actually diagnose this I recommend following the service manual flowchart for code 21. Ohm out the harness, coilpacks, inspect the ECU, etc. And again, it's entirely possible for there to be no problem at all but if you're running a different coilpack it'll trigger the code because it doesn't like what it sees.
