Have Toyota Questions? Ask a Mechanic for Answers ASAP
Hello and welcome,
Is the vehicle running normally with no drivability issues, stop and turn normally? The first thing that should be done is to find out why these lights are on by connecting a diagnostic scanner to read the trouble codes from the computer, the check engine light may very well be the only reason for the other lights to go on as these systems are disabled as long as the CEL is on. Did you get fuel recently? Was any maintenance or repair work done before this happened? In any case we need the diagnostic codes to determine what needs to be done to fix this, you can visit any of the large autoparts chain stores and they can help you with getting some code information out of the computer(except in Calif) they do this at no charge, then please reply here with the diagnostic information and we can continue from there. What you can do yourself before doing that is to make sure the gas cap is tight and the seal is not damaged, look under the hood for any vacuum hoses or electrical connectors that may have become disconnected, clear the lights by disconnecting the negative battery cable and then drive it normally a couple of days and see if they turn back on.
