Hi all. We have a Cat 745c TFK prefix that randomly the screen shows stars instead of values and then cluster engine temp goes to to the red mark. Throws all kind of codes related to communication and ecms and can and cat data link. We have checked all plugs and nothing changes. Sometimes happens in the morning sometimes at the end of the shift sometimes doesn't happen in weeks. It's driving us crazy. Anybody with a similar issue?
Got a list of those Codes.?
