Hi,

The first thing that should be done is to connect a diagnostic scan tool to the car's on-board computer to find out what the trouble codes are, usually the check engine light causes the other warning lights to turn on since those systems are disabled when the check engine light turns on, the check engine light should be diagnosed first. What the problem may be depends on the trouble code numbers that are stored in the computer, I would recommend having the Toyota dealer retrieve the codes if possible, if the dealer is not an option then most autoparts stores will get the codes for you at no charge, try autozone, they will give you the code numbers but little else, if you need help after the codes are retrieved please get back to me, please make sure to get a printout of all the trouble codes.

Let me know,if needed further assistance.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!
