I have the three amigos on, disco mike says since my brakes are squeeling, its most likely the speed sensors which means I need new brakes. I checked the codes and p1590 was the only code that popped up and I was searching around the forum and it seems like that code is fauly speed sensor..., is that true? also not sure if this makes a difference but as soon as I start my car the ABS light comes on instantly and after a few seconds the TC and HILL DECENT control then pop up, not sure if that means anything.

 

The 1590 is a Rough Road/ABS fault code which will always come on when your 3 Amigos are on, it does not mean anything else, so go get your brake squeak issue resolved and then find someone to read and clear your ABS faults.
