Every time I go to check the code on my tuner nothing shows. It's hard to get to the code reader on my tuner while the light is on. It doesn't stay on very long. It started by going on and off maybe once a day. Now it's going on and off every 3 minutes during a drive. I'm guessing I have a broke or frayed wire somewhere but I don't know where. But I could be way off. The only wiring I see under my seat goes to the seat belt.
