All 3 brake lights don't work and the ESC dash light stays on. Cruise control does work.
Do you

This could be a number of things. We need to start with pulling codes.

Here is a video on how to pull airbag and ABS codes. You will need to be able to access the abs module for codes in order to pull them all.

Let's start with the codes from this system and go from there. They may all be related or the ESC light could be different from the brake lights and Cruise not working.

Let me know what codes you are seeing and we can go from there. Thanks

Is that the issue or was the what you had a DTC for? Clearly that makes sense but I am just confirming you repaired it with that part or need more info. Thanks

Here is the info for this code. I just want to clarify if this was replaced and it fixed the vehicle or it hasn't been done yet? Thanks for the updates so far.
