when I put my care in reverse the backup lights do not come on.

Check fuses!

I think you got the odd-ball problem of the week award. Never heard this happening (SOP for Toyota Service). I can't imagine the TC light coming on just because a tire was not in contact and that certainly wouldn't have kept it from going into reverse. I would report it to the dealer. Where there any other warning lights on?http://www.lightdeal.co.uk/
