Traction Control & Engine Lights

[BOBBOS]

The TCS/Slip & Engine indicators lights during normal drive, can anyone tell me what causes that and what I need to do to diagnose exactly where went wrong?

thanks heaps

By the way, its a R34 GT-T

is the car modified?

we have done one with a Plazmaman plenum which requires the stock throttle body to be changed

which in turn throws the same lights as your car

still trying to figure out a work around for this issue

Thanks for the reply, no I haven't modify my car...

So you reckon there might be something wrong with the throttle that trigger the TCS lights?

I'm having the exact same issue lol

I got my R34 GT-T not even a couple of weeks ago and this happened to me for the 3rd time just earlier tonight. Driving along, car seems to go a little funny for a moment, but keeps traveling along just fine. TCS Off, Slip and Engine lights come on. Pull over, turn off car for a few secs and restart it and it's fine again.

I checked the ECU Fault Codes (shorted pins on consult connector), engine light flashed Code 21. I've been reading up on this over the past few days and yeah .. Pretty much what JI34GT said. Err 21 pertains to the Ignition circuit and is well renowned for being problematic coilpacks. The general consensus is to replace them. That's what I aim to do over the next few weeks. Do a search and you'll find other threads on the topic.

The only question I have now is why Nissan made it so it lights up the TCS/Slip lights .. Bit misleading isn't it??

Fingers crossed it'll fix things up, might be good for current/future power gains and possibly also bring up fuel economy a bit if it's been crap.
