As previous posters have said, traction control light is not a fail item. It'S worth checking the TC switch hasn't been knocked. On many cars you can turn the system off and the TC light will then be illuminated. HTH Fav

'Traction Control' and 'stability control' functions are different. Traction control will reduce the slip at the driving wheels under acceleration (usually by reducing the engine power). This is measured by taking a reading from the ABS wheel speed sensors. Stability control reduces and attempts to prevent the car losing control due to spinning or going into a sideways slide due to loss of grip from any of the tyres. The measurements for this function are taken from ABS wheel speed sensors, lateral or yaw sensors, steering angle sensors and possibly some others an the latest models. This can be done by reducing engine power or applying one or more brakes, or a combination of those. So 'traction control' only operates under acceleration. Stability control can operate at any time whether accelerating, braking or cornering. Traction control by itself is not considered a safety feature generally it will only come in slippery conditions such as greasy/wet roads or icy/snowy roads. It helps the vehicle to get moving and accelerate without wheel spin. It can usually be easily switched off. Stability control IS considered a safety feature in that it helps to prevent loss of control of the vehicle - especially when baking and cornering on a slippery road surface. This is only a quick and basic description of the difference between the two systems and what they are there for. Hope that helps Fav

Is Traction Control, which by its wording says that it controls traction (wheel slip) the same as Electronic Stability Control, which controls traction at the road wheels not also the same thing?

There is a difference between traction control and electronic stability. Without going too deep into the workings of a electronic stability control system,traction control makes up part of it to work In conjunction to help the stability of the vehicle during adverse conditions. On the other hand traction control on its own is not a testable item as its more to do with helping traction in order to help the performance of a vehicle under hard acceleration. In my opinion traction control lamp on is pass/advise.

Is this a failure or pass and advise, nothing in rfr actually stating that traction control is a failure . I had a Astra in last week where the light was on. And after a phone call to vosa ( not just admin workers.) he said in his opinion that TC is a pass and advise. But read in the motoring column today in the Sunday mirror , that it is a failure. ( but we all know to take with a pinch of salt what quinten Wilson thinks )
