I believe that the TC system works by cutting the power to 1/2 of the cyinders . But does this depend on the lack of grip, ie little slip cuts one cyinders, lots of slip cuts 2 cyinders or is more of a all or nothing system.
Thanks
Steve.

It applies brake to spinning wheel. If that not cure wheelspin, it drops 2 cylinders I believe, if still not preventing, cuts more

Doesn't feel like it drops cylinders on the DBW cars. I reckon it just closes the throttle.

Ah, could do.
I did read up on it, but that was a fair while back :-[

Just an observation having played in the snow. Once TC has kicked in you can do what you want with the accelerator pedal - even floor it, and the engine runs smoothly with just a little wheel slip. As it gets traction, it gradually adds power until it slips again, then reduces it again. Throttle just seems to set the maximum power it will apply if it thinks it has grip. ;D
It's as if the TC just takes over control of the throttle via CAN.

well it certainly drops cylinders on the non-dbw cars

I didn't realise that the Omega could apply the brakes :-/
The TC on my 1994 manual 2.5 V6 CD was useless. Hit a wet manhole cover with the throttle open and one wheel would spin up, the TC would cut the power, the wheel would stop spinning, the power would return and (without spinning a wheel) the TC would cut the power again. If you kept the throttle pressed it would kangaroo up the road >:(
It would do the same if you opened the throttle on the crest of a road hump. ::)
My 2003 auto 2.6 elite is far far better. On the same wet manhole cover I can floor it and not feel when the wheel is on the cover.
On the sheet of icy snow outside the house I have noticed that there is a 'new noise' that I couldn't identify. Wondering now if it was the ABS pump activating the brakes?

Yep... To the point where if it's still struggling for grip you stop moving if you don't switch it off ::) ::)

Same as mine then. ;)
Unless yours is fubar'd too as TB suggests with mine ::) ::) ::) ;) :y

Only mini facelift and better apply brakes, as its a true 4 channel system. Pre 1998 is a 3 channel system, thus ABS ECU canot brake individual rear wheel

The system works pretty well when working, but cannot overcome poor driving - floor pedals on slippery surfaces is goign to be like floored brake pedal in this weather; the system will stop the wheelspin, and reapply all 200bhp, then light them up again.
So, either yours is bust, or you can't drive :P
I assumed the former ;)

Mine is fine but my road is now so slippery I can only just get along it being very ginger with the throttle... Night before last it wasn't as bad as now and all I did was select drive and lift of the brakes (no throttle) and the rear and was fishtailing :o :o
Stil driveable, but with care and generally with TC off ;D

Wasn't at that point... it's now the only way you can get along the road and need to use more throttle than you'd like because the snow/slush.soft ice is so deep :o
May have to get out there with a shovel and clear some more ::) Trouble is, only the guy next door to me has made any effort with a shovel... Everyone else would rather struggle >:( >:(

Yeh, it improved mid 1997 when the 4 way ABS unit arrived....earlier versions had a 3 way setup which was not as advanced

Yep. You can hear the ABS pump start (and see the lights go dim at night. It's obviously thirsty).

I'm with you Lazydocker ;) If the road is ice, no amount of electrical aids is going to make tyres grip. My Omega was last used between Christams & New year when it snowed then. I took a run up ... twice ..... but it wasn't having any of it. :y

Snow mode on box, and TC can help though. But you can't put a shine on a turd, if there is zero grip, there is zero grip!

Yep... That's the problem at the moment. Still... It's just about doable ;)

Another nice surprise :y
I have had this car since September and I am still discovering improvements that GM made that I wasn't aware of :)
I now realise that the facelift is much more than just a tacky nose job and a cheap looking interior :D

Many of the technical improvements came in with mini facelift, including the ABS one. Facelift introduced a few 'comfort' improvements - eg superior climate, better seat heating etc.

better rubber paint on grab handles etc
..... or is that rubber paint that is better at coming off? ;) ;)

Glad I found this post. I was getting worried.
After a short while of spinning wheels in the snow my engine sounded terrible...popping and spluttering all over the place...kinda mis-firing as if she'd lost power from a couple of cylinders ?
