Stop engine light question
Had the dreaded stop engine light and alarm come on. I found I was just low on coolent. Added coolent and light went out. Now to my question, does the engine also derate when the stop engine light comes on? Mine did,so am wondering if I have another issue or does it derate every time the stop engine light comes on. Just in case, I did change fuel filters as well and will now test drive. Or should I also go to Cummins and have the codes read? Thanks for your thoughts.
