2F49 - DME: EWS preventing manipulation
So I had a mosfet go bad on my ECM, and I just bought a used one and took it to a shop to make it work in my car. And I just fixed my original ECM today and put it in. but now I'm getting this code and the car won't start. It's just cranks. Is there something I could do to get to fix communication between the CAS and DME?
