This topic was discussed in the forum before, I did a lot of research on this issue, but I did not find clear answers, I installed the speed stabilization keys on my vehicle, I activated it from bcm, but it did not work, I have a full package bcm and empty package bcm picture and I have missing parts and therefore I think it does not work and what is that part. I am searching the code that says is on it. Is there any friend who knows about this
