When you press the VSC off button does the VSC off light come on in the dask area?
Can you check and see if the button is plugged in?
Do you have a way to pull codes from the computer? If there are any stored.
No I have no code readers.
I have no traction conrol ever. The VSC dash light bulb is ok. Also the abs is not not functioning.Could it be a ecu problem?
Yes, this could be an ECU problem. The VSC OFF button is just a switch to ground for the computer which when pressed, the computer turn off the VSC. Either that circuit is faulty or the computer is.
if so where are all aplicable ecu's located in the car?
We can list them all but that won't help us at this point. The first step is to use a scantool and see what if any codes are stored. You can also check and see if all the fuses are good(both under the hood and the lower dash)
