Have Toyota Questions? Ask a Mechanic for Answers ASAP
Hello and welcome to just answer and allowing me to assist you. If your husband noticed a orange light flash on and go off most likely it has a stored trouble code in the ECU. if the light doesn't stay on then it's probably a pending r history code that has to be pulled up by a scanner tool preferably a shop scanner they give more detail to exactly what it may be. until you have it scanned it's any ones guess what caused it because there are so many electronic devises on these cars. Hoe this gives you some direction where to go with this situation, If you need further assistance I will be happy do so.
