Default Master Warning Light / Check Engine Light - then off

We are on a road trip on a Saturday night. We need to get home tomorrow, driving through Nebraska. While on a an hour and a half highway trip the Master Warning light (triangle with !) and Check Engine light came on. We had to replace the headlight last night because where we are there is not a person in sight who can service this car.The nearest Toyota dealer is at least an hour and a half away. When we turned the car on again after pulling it off the road, the lights went off. There is no indication that anything is wrong with the car. We took it to a guy in town who ran a computer diagnostic and said it didn't show anything. Do you think this is a glitch? Can we make it home (600 miles) tomorrow or should we try and figure out how to get it to a dealer on Monday?

It is a 2007.

Have you had the recall done on your inverter coolant pump? You can check to see if it's working by checking the inverter coolant tank with the car in READY or IG-ON. You should see turbulence in the tank. If not, the pump has failed and the inverter is overheating. I would not drive the car more than a short distance if the pump is not working.
