I was driving 25mph. Heard a few dings alerting me to something. The engine reduced power. I pulled over and the engine light and traction control light both came in. Warnings said service traction control and oneother I couldn’t recall. A few minutes later I started it up and it sounded fine. The engine light was on steady and it ran fine. Later the light went off. Code reader showed U0100 which is Lost Communication with ECM.
It’s running fine now but I need to figure out what’s going on. Sounds pretty expensive. Any ideas?
