Hello,
Yes, the ECM is located below the fuse box under the hood.
Remember to retrieve the existing ECM data before removing it, using an appropriate scan tool.
I have attached the replacement procedure as well as programming procedure below for your reference.
Let me know of any questions.
Thank you.
