Beau Posted June 15, 2011 Posted June 15, 2011 Hi guys, I am having a problem with my 350z. The traction control light and slip light comes on as soon as I drive off. A few times, at low speeds, the abs also kicks is at the front wheels, mainly right. Once restarting the zed, the light is off until I start driving for 50 yards or so. I have read that having the wrong tyre size can cause this. I am running 265 35 19 in the front and 285 35 19 rear both on 9.5" wheels. What size are tyres are you guys running? I have also read that there could possibly be a problem with the wheel sensor. I have swapped the sensor and the hub and this has not made any change. Also read that low brake's fluid can affect it, but it is fine. Has anyone else experienced anything like this? Any help much appreciated! Quote
Neilp Posted June 15, 2011 Posted June 15, 2011 245/35 on fronts (8.5j) 275/35 on rears (9.5j) Im sure people who run the 285's on rear go for a 30 profile. Im sure someone with the calculation will be along soon to advise facts Quote
RisingPower Posted June 15, 2011 Posted June 15, 2011 Odd that, only 1.3% off the front and 0.6% off the rear. 30 on the rear on that size wouldn't be brilliant. I guess maybe your front is a little bit off but i'm not sure that's really the issue here? What about running 255 at the front? Quote

Hmm that would be very stretched on the tyre, and is not what Im after... Quote
Neilp Posted June 15, 2011 Posted June 15, 2011 245's dont look that stretched on a 9.5j rim. Theyre not that extreme but just look a little stretched Quote
ATTAK Z Posted June 15, 2011 Posted June 15, 2011 I am running 265 35 19 in the front and 285 35 19 rear both on 9.5" wheels. Your wheel and tyre sizes are fine Beau ......... fronts are +1.27%, rears are +0.65% ...... both well within the 2.5% recommendation Quote

I made sure of this when buying the tyres! So what could the issue be? Quote

RisingPower Posted June 15, 2011 Posted June 15, 2011 Hmm that would be very stretched on the tyre, and is not what Im after... What width is the front wheel? Incidentally, I doubt it's the tyre sizes being that close. Quote

RisingPower Posted June 15, 2011 Posted June 15, 2011 All the rim width are 9.5". That's hardly stretched then. If you're saying 9.5" square, 285 at the rear seems a bit too fat tbh. I guess you could run through the technical handbook, seems to have masses of stuff on tc. Quote

Beau Posted June 15, 2011 Author Posted June 15, 2011 It also says if there are problems with the throttle control system those lights will be on. Is there anything that goes wrong with the throttle control? Quote
Daryl Posted June 15, 2011 Posted June 15, 2011 Iv recently had this issue,and then i lost my entire dash and trip computer,no revs,speedo,fuel etc,TC ABS etc. I think iv sourced it down to a faulty relay,as one of the fuses (bottom row nearest the bulkhead) blew,then kept blowing (so to speak ) Iv got another relay coming tomorrow,hopefully this will fix the issue,but il keep you posted.

I dont think my problem is as bad as yours. Tomorrow I will give thr throttle body a clean and see if this makes any difference. Other than that, I cant see what the problem could be. Quote
Daryl Posted June 15, 2011 Posted June 15, 2011 Was the worst timing for it to happen,just about to get on the train to go Lemans. lol Hopefully the relay will solve the issue. Quote

Daryl Posted June 16, 2011 Posted June 16, 2011 Well iv replaced the relay,which is what i thought was causing the issue,but that has had no effect. It still blew the fuse the moment i turned the ignition on. This could be expensive! Quote
