I had this problem before but never found what caused it. basically i'd be driving down the road, and the vsa light and triangle come on and stay on. If you shut the car off then restart it, the lights go away and stay off. This happened to me a couple months back but it hasn't happened again until yesterday. I've checked wheel speed sensors, tire pressures, anything that has to do with the rolling assembly's and everything is great. Also scanned the computer and tested the abs system and everything is fine and there are no codes stored anywhere.
wtf is going on? My car is lowered on Teins and Tokico's and stock TL wheels. no brake mods or anything.

 

This happened to me not too long ago. Basically, the dealer traced it to a faulty brake switch. They replaced it and I haven't had the VSA come on ever since.

 

this happened to me twice already too but my car is pretty new like less then 2000 miles
