AFAIK you will need to get the "new" tcm flashed by a dealer.


And, WTF were you thinking working on the fuse box (or anything on the electrical system) without disconnecting the battery???????
Hope it was only the tcm you fried..............

Yeah you need to flash the vin to your tcm as long as the tcm is suitable to your car. !!

I know with the BCM you have to match old part number to new part number otherwise they won't be compatible with the car.

With the tcm it needs to be the same.

Going to need more than a TCM if power steering is inoperative....
