Have Toyota Questions? Ask a Mechanic for Answers ASAP
Hello, my name is ***** ***** I am a professional here at Just Answer. I have noticed that your question was not getting a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.In order to begin to know where to start the diagnostic the first thing that needs to be done is to scan the system to see what the fault code and or codes are that should be setting when the check engine and AWD light is coming on. If you can get this done and post back with them, I will advise from there.
