TC control light (Opel Vectra B)

You have already read about how the traction control system (TC) works in the Vectra with a 2.0 litre engine in the chapter on ABS in this book. If the TC system has to reduce engine power or brake the wheel due to a spinning wheel, this is indicated by a flashing TC indicator light at the bottom right of the instrument cluster.



For purely functional control, the light comes on for a few seconds after the ignition is turned on. If the light remains dark, the incandescent bulb is faulty (for replacement see above in the chapter) or there is a malfunction in the vehicle system. There is also a defect if the control lamp is constantly on while driving.

Of course, the indicator light also lights up when the vehicle is switched off manually as a reminder - and not longer than the engine restart. Therefore, when reporting a defect, first switch off the engine and restart it. If the light still lights up, a workshop should help.
