Title: TC Confused
Post by: Kevin Wood on 03 December 2010, 00:09:52
Somehow managed to confuse the traction control today. :-[

Set off from work - car park like a skating rink so from the moment the car started moving - in fact, as soon as i put it in D, and with no throttle, there was wheelspin and some sideways action at the rear. ::)

Stopped by the stores door to pick up some items I'm "removing to a place of greater safety" ::). Got back in and noticed TC light on. Drove off and gearbox permanently in snow mode (pulling away in 3rd). Couldn't disengage snow mode nor switch TC on/off.

Shut down and started it up again and everything normal.

I suspect the ABS/TC ECU likes to see all 4 wheels moving at a plausible speed as the car pulls away for the first time or it throws its' toys out of the pram. ;D

I had similar pulling away from the Burger King (my colleagues made me ::)) - I nice 180 degree turn to get out of carpark...   ...So I thought I'd "have meself some fun"

In my case, it was the gearbox, not TC (as that was switched off), and I filled my gusset when it banged into limp, as when it banged, I thought I'd hit the kerb...

I would have checked it for codes had it not been -6 by the time I got home. ::)

I have the same problem but mines intermittent was wondering if there's a sensor for it.

I actually had the Tech2 on the front seat (for other reasons), but still couldn't be bothered...  ...my face had an urgent appointment with a Whopper Meal ::)

For TC?  Ice/Snow aside, it doesn't get confuddled.  On a post 98 car, I would beging to dread the worse :(

rolling riad caused similar as Steve says, but yours hnas the additional stuck in snow mode thing. Could s.m. have been on prior to fuddlment and it just stuck due to a perceived fault?

Nope. I never use snow mode, even in snow. ;)

TC light on, not responding to TC switch.
Gearbox starting in 3rd and snow mode switch had no effect on that.
It had certainly got into some sort of "safe" mode.

As said, I shut down at the next junction, then pulled away carefully and it was happy. :-?

Is there sensors on the back for the Tc or are they intergrated with abs sensor I just don't see why it's perfect all day then I turn car off and back on and the traction control comes on grrr

Trying to work out my gearbox limp, and can't - it has engine speed, it has output shaft speed sensor, and it knows what gear it thought it was in.

Like yours, I am beginning to suspect external factors causing it (in my case, ABS/TC confuddled, though neither of those threw a rod AFAIK - orange light was on anyway as I had disabled the fun spoiler TC)

Nope, TC entirely uses ABS system and it's sensors, as well as the ABS - Engine communiocations channel

I suspect the gearbox detected TC was not playing and went into "litigation avoidance" mode. I guess if this happened in your case, as TC light was already on, you'd not have noticed?

Although it begs the question, if you'd already turned off TC, why didn't it leave you to it.

Just remember that the gearbox-ABS(TC)-Engine ECU are a little more sophisticated on the 2.6/3.2 with CAN bus between them.

So having seen the TC throw a fault message out, the autobox might take offence!

Last time I opened the bonnet (earlier in the day as it happens), it looked like a 3.0l to me ;D ;D

I suspect it was still some convo going on between engine/box/abs, though never happened before  :-/, not that I've tried  [smiley=engel017.gif]  ::)

S'pose I really should plug the Tech2 in to see whats stored...  ...but it looks chilly out ;D

Nah, thats sat on the driveway, under a heap of snow and ice.  It doesn't get used much, done about 1k since July in it...

I think it needs a new battery - 2 weeks of no use, it normally doesn't like starting.  Not tried since the cold snap, I suspect it won't even turn over ;D

i am pleased some else managed to confuse the abs/tc, as i did this the other day with my 99 2.5 auto.  rear wheels spinnin at bout 75mph front wheels doin less than 5mph. i tryin my hardest not to get stuck on a hill and rear offside wheel was against a kerb all the way lol

As said above once i turned ignition off and back on all was fine, altho i didn't notice if gearbox was in limp mode.  i have had the gearbox fault where i had to remove selector and clean (milkshake inside)

Rolling road does make the TC light stay on and does go off after a few yards normal driving, but it doesn't put the box into limp mode.

Even on the later half CAN Vxl models with autobox and ESP/TC that you CAN'T TURN OFF  >:(, on a rolling road it just throws up a fault on ESP/TC after a few seconds popping and farting but the box still works as normal. Turn ignition off then on and alls fine in the stability world.

Could the cold have affected oil flow in the box and under the 'extreme pressure of hard acceleration' caused it to go limp?
