Title: TC on a 2.0 GLS
Post by: Marc Taylor on 30 August 2010, 20:02:36

Would my car have tc on it as it is a gls? there has been a few times iv had the car going sideways and no indication of the light coming on or sudden power loss to the wheels.  Just be nice to know really or is this something else that i may need to sort out?
Thanks for your help

Sorry to hijack this post. How does TC work on the Omega? When driving my dads old V70 slowly on snow, TC would kick in and it would sound like some sort of ratchet, but still keep drive onto wheels, yet in Omega it just seems to cut the power - how does it cut the power? I'm thinking fuelling, ignition, I just don't know? Thanks

It will attempt to transfer torque to the wheel with grip by braking the spinning wheel. If it decides it needs to cut power the engine ECU is told to reduce torque which it probably does by a combination of ignition retard and dropped cylinders.

I find it works OK on gradual loss of grip at low speeds - muddy fields, etc. It cuts the power a bit to aggressively for my liking when it operates during hard acceleration. Interestingly, my Dad has a V70 and has been stranded at times on snow and had to turn the TC off to get moving. I've never found I can do a better job manually than the Omega TC in such instances.
