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.The 4X4 light flashing indicates the system is seeing a fault and when this happens the system will detect it and set a fault code and or codes. In order to determine what is failing you are going to need to start with having the computer system scanned and the fault code and or codes retrieved. If you can get this done and post back with the results I will see if I can help you determine the cause.
