2004 Lexus ES330 Q&A
2004 Lexus ES330 Question: TRAC, VSC and Engine lights are all on
Your Lexus has On Board Diagnostics 2 (OBD2). There is a 16 pin diagnostic socket under the dash board. Your cars computer has seen a problem with the vehicles emission control system that may or may not also exhibit a drivability problem. Many things can be responsible for illuminating the Check Engine Light and the computer monitors many sensors for opens shorts and performance. Many of the power train sensors are shared by the traction control system. You will find by fixing the Check Engine Light the TRACTION CONTROL, and VEHICLE STABILITY CONTROL lights will turn off. Even a pretty generic (non Lexus) scan tool should be able to read the problem. - patrick mannion
