VSA light turning on

Hi, does anyone know the reason for my VSA (traction control) light to come on? I own a 2008 honda civic si. I remember I broke hard to a stop since someone cut me off. The day after that the VSA light kept coming on if I turn hard or if I brake. I’ve heard that it could be from my speed sensor or vsa modulator. If the vsa modulator is the reason, where’s it’s location? I don’t really want to take it to the dealer because last time I went to them to replace a motor mount and starter, they tried charging me 2k so I ended up doing it myself.
