2007 Thomas EF ISB 5.9. Upon start up odometer reads ICU 140 (NOT ECU.) No Check engine lights, or stop engine lights illuminate and the bus runs fine. Once its run awhile the message disappears. What's causing it, and is it anything I need to worry about?
Thanks

Figures it would be something to do with the gauges. Replaced them 6 months ago. They work fine, not going to worry about it. These buses really are garbage
