Stop Engine and Check Engine Light
A few times since buying our 08 Berkshire, the Check Engine and Stop Engine lights will come on and chime and then within seconds, go off. I finally learned how to use the FR system to retrieve the codes but there were no listed. Today, while running the coach home from getting registered, the lights came on again. I was able to stop immediately and check but again, there were no codes listed. The engine, cooling and transmission diagnostics all show clear. What should I try next? The coach runs smoothly, perfect temp range, no loss of power...
