Yup, same engines. The escape system is an integral part of the vehicle (rather than a bolt on system as with tractor abort) and is regularly used and tested. And because the escape system is always there it means they can abort at any point during launch all the way up to orbit, which is fairly unprecedented. I believe they can generate 8 gees of thrust with the escape system which would allow them to escape even if the rocket doesn't get shut down during an abort.
