Toyota Repair: Sienna 2004, engine management system, information numbers

Question
Hello .... I was driving when I notice the check light, trac off, and the vsc light came on. This is the first time I saw this ..... I went home and park the van and turn it off and turn it back on and the check light came on first and then the other one on and stay on .... The lights are solid and not blinking. Can you tell me what is wrong and if I can fix it by myself ? Help :( thanks

Answer
The check engine light turns on because the computer has detected a problem in the engine management system, the other lights turn on by default because those systems are disabled as long as the check engine light is on. The first step is to find out what the diagnostic codes are stored in the computer. I see you live in DC, there should be an autoparts store near you like Autozone. Kragen/O'Reilly, NAPA etc, take the van to one of them, they usually help you get the diagnsotic information numbers at no charge,then you casn let me know what these numbers are and I can help from there.
