Toyota Repair: malfunction, toyota highlander, indicator lamp

Question
This morning, while driving on the Interstate, the VSC TRAC warning light went on, as well as the Malfunction Indicator Lamp (engine light).I have 2003 Toyota Highlander.
 Thanks

Answer
The check engine light is the root cause of the problem, whenever it turns on the other systems are diabled and the lights will turn on. You should have the fiagnostic trouble codes retreived. If there is an autozone store close by contact them they will do this at no charge so will most large autoparts chain stores. When you know the codes post a follow up if help is still needed.
