Check the fuse and see if cruise cable is brittle and dry then put some wd40 to free up the moisture.

White smoke caused by engine head gasket leak allowing coolant to be mix with engine oil and due to same your check engine light is on. Traction control may be because of same issue or may not be, im not sure.

You must also be experiencing loss of power from mild to severe grade thats a key indicator of head gasket leak. If your coolant level is low and engine oil turned milky substance then its for sure you have head gasket leak there.

Its a serious job as you have to open the engine head so seek a qualified technician only.
