Looking for some help, I have went the google research route, some forum digging and just getting too much conflicting information so Im here to ask what I thought would be easy to find questions and answers.

I have a 2015 Mustang GT manual, the pcm failed one of the coil drivers, confirmed by opening the PCM to see the driver is shorted. I am now looking to replace the pcm all together, while researching I havent found anything that answers my questions directly.

1. Can I get any pcm from ANY 2015-2017 mustang to replace it?
If I cant get any pcm, how would I know what PCM is compatible or is new the only option?
Can a used pcm have the VIN changed?
If so, is a dealership the only way to have it reprogrammed?

Thanks for any responses.

Having same issue.

No

If I cant get any pcm, how would I know what PCM is compatible or is new the only option?


Your PCM should be a
FR3A-12A650-EDB or FR3A-12A650-EDC if you're a V8 with manual transmission


Can a used pcm have the VIN changed?

Not by my dealer anyway

If so, is a dealership the only way to have it reprogrammed?

It's VIN locked, dealer can't change VIN on PCM, buy a new one.


FR3A-12A650-EDB are discontinued.
FR3A-12A650-EDC still available

I ended up repairing mine. If it's a coil driver failure let me know, I can very likely repair it for you and save you a ton $$$.

Can you post up some images to the “coil driver” failure reference??

I only have this one picture, you can see the bluish tint on the mosfet. Compared to the one on the right being nice and shiney silver still.

From what Ive gathered and my theory, there is no protection for the coil driver if the coil fails, I ordered what I thought was motor craft coils, they were knock offs. Drove down the road about 20 miles and lost a cylinder. I ended up with a melted coil and this little mosfet burnt up. Swapped mosfet, replaced coils with OE from Ford and haven't looked back.
