Vsc & Trac & Abs Lights On

[skeet94]

OK Got the ball joints done, total cost of £200 with Balljoints and Labour.

Now that that's been sorted out, the VSC, TRAC (meaning Traction Control Off) & ABS Lights are constantly on, on the dash.

Just curious but why is this? I've been told the sensor wire might be broken.

I've tried resetting the ECU but to no success.

It's one thing after another and I'm getting fedup now :(.

Anyone? help?

[Mr Morse]

Like you say, it is probably the sensor either not connected properly or it's broken - take it back and make them fix it.

[Gord]

As Mr Morse says take it back for them to look at :D

[skeet94]

Thanks Mr Morse & Gord. Calling up this morning to give an earful to the mechanic.

That's the ABS sensor that's broken probably...good luck re-setting your ECU.

Even after you fix the ABS sensor, it could still be screwed (the ecu).

Let me know if it resets OK!

[skeet94]

Yoshi, I'll send you an email in regard to the ECU resetting. If you could maybe let me know how I could go about doing it :). Thanks.

I had the same problem on my mk11 aristo, changed the ABS cable/wire and all was well again.

My car that has just arrived in th uk has a trac light and abs light on as well. Wonder if putting it on the boat or having no Battery on it for so long has caused a problem.

It's not the Battery.

Check the sensors.

Colin: Thanks for the link, was wondering if there's another way of resetting the ECU. As from what I understand from Yoshi's post is that it might be a bit of a headache to clear the error after it's done.

Dangerous Brain: Yep it's most likely going to be the sensors, if you can't find a reasonable priced garage to do it, give me a shout.

Thanks for all your replies though, have ordered a new ABS Front NearSide Sensor.

Also is it just me, or is it more "fun" to drive the car without the VSC & TRC functioning. The car feels VERY light and feels like really "nimble" as opposed to a heavy yet very SAFE car when the VSC & TRC are working normally.

[dangerous brain]

Cheers skeet chap. If its sensors then I am sure I can replace them myself if I can actually source them.

As for trac control limiting fun I'd have to say that the stock ones trac on a supe is almost dangerous with its all or nothing power cut. I don't think the traction control will be working on mine when it shows up which is no loss to me as I am gonna put rltc on when i have the cash

[norkep]

If the sensors light up while driving randomly, best check the earth for the ABS pump, reason - mine is doing this and when I had it checked out, the ECU Diag's showed this as the fault but there's alot of earths around the pump that any one of these can cause this, it's a time comsuming job and can work out to be expensive to fix.

OK...yesterday went to the hospital to have my Physiotherapy and on the way back I tried getting out of a road really quick...what happened? I sat there spinning away *sigh*...I think the trc does actually help in these situations, the good thing is it doesn't really give as huge of delay in response...it's almost instantaneous.

Got the Sensor put in today, reset the ECU, the lights still stayed on...then took it out for a really quick drive and performing a few emergency brakes ... the lights went away themselves :D I'm a very happy chappy now :D.

Dangerous Brain: The TRC is a good thing instead of not having any as I managed to find out lol...in poor weather it would definitely help with standing starts but can always turn it off...I was also looking at the RLTC...got any experience with them? How good is it? etc.

[dangerous brain]

Oh yes I have a great deal of experience with RLTC. Its saved my bacon as many times as I care to think. It also makes my car so much more driveable in bad weather and atrocious road conditions. I find the stock TRC on the supra woefully slow and quite dangerous. My car if you switch the RLTC off in a dry carpark you can fully 180 the car from a standstill with full lock on before the TRC cuts the fuel, it then proceeds to keep the fuel cut for about 2-3 seconds not really ideal in my book. RLTC will just keep pushing you in a circle even with your foot planted to the floor back it off a couple of settings and the back will break out a bit and you'll get a bit of a power slide.

[skeet94]

Dangerous Brain: Same sort of thing I read on www.supraforums.com where it helps ALOT with higher power Supra's...but knowing someone over here's had the same sorta positive experience is making me consider it too lol.

Although I do know that the TRC on the Aristo isn't AS BAD as the Supra one or the IS one...since it doesn't really cut fuel THAT badly...but it does tend to interfere in certain situations involving powerslides. I will definitely take the RLTC into consideration though...seems like it's definitely what'll be needed for higher power.

Did you have the launch control fitted too in the Supra?

[dangerous brain]

Launch control

Yeah it has but to be fair its an auto so pointless

Theres lots of supes in the uk with RLTC

[skeet94]

OKAY That's my next mod on the Aristo!! Thanks for the mini-review Dangerous Brain :)

[dangerous brain]

So how do I go about checking the sensors on the abs system then????

the way to reset the sensors manually is to drive at approx 4mph for 100meters, then the sensors will self reset,

[skeet94]

I had someone who had access to a computer for the Diagnostics port and reset the ECU, but thanks anyway Ahmedm :).

Any pics of your Aristo? Also welcome to the club (although it's your 2nd post).
