Hello all...I'm new to the this forums. I own a 2002 RX300. Earlier this evening i noticed that the VSC, TRAC OFF, and check engine light all came on. I'm lead to believe that something went wrong with the VSC which caused the TRAC OFF light to come on...which also caused the Check Engine light to come on. Anyone else ever have this problem. I suspect it's probably a sensor or something. Any info would be great. thanks in advance
