Most of the times when I turn my car on the brake, dct, and abs light all come on and stay on They are all light up yellow. Does any one know what this means?
Here's a photo.

 

That is the dreaded 'trifecta'. You, more than likely, have a tire rotation sensor failure or one or more tires that are under inflated. It is not necessarily a panic situation but should be corrected in a timely fashion. Most on here would recommend you take it to an independent shop rather than a dealership mainly for direct diagnosis/resolution and less cost. Dealerships mainly just throw new parts at problems without really indentifying the initial cause.

 

If the tires were under inflated then wouldn't the tps just go off? And do you think I can fix this with a code reader?

 

Usually its just one tire that relaxes setting of the rotation sensor. In the case of the trifecta, there is a system failure of some sort. All the code reader will do is tell you what the three lights are telling you, sumptin ain't right. You need to get it in to the shop.
