You have a failure in each of the systems listed, get the codes read, that should tell you where to start. Don't disconnect the battery attempting to reset the system as this can and does cause the system to totally shut down and then it has to be reflashed by the dealer to bring thing back to factory settings.

Ok, who 'reads' these codes?

Some parts stores can pull them, but your best bet is a shop, they can pull everything at one time, a parts store may only be able to do engine.

Did you end up getting it checked? What was the issue? This just happened to me today. All same 3 lights.

I hope this helps everyone dealing with this RAV4 mystery ... All 3 lights presented on my panel yesterday so I drove the car to the dealer. Dealer ran diagnostics and brought the following codes: P2401, P2402, P2419, P0456, P043F, P043E. Quoted nearly $2k for parts and repairs!!! I immediately began researching - best site is RAV4world.com I discovered that for the last 20 years Toyota has been selling us vehicles with faulty emission systems with a TSB (technical service bulletin) but no recall. Dealers are making a small fortune charging for anything from O2 sensors to a new emission system - and guess what? There's more! After investing all that $$$$ the lights may still come on at any time. My 2009 RAV4 has 32,000 miles on it and is paid off. I had intended to keep this car until the wheels fall off. Research your problem thoroughly! I became familiar with the following website
