Jeep Strokers

This check engine light and “no Bus” visual first showed up about a week ago. I took apart the dash and cleaned and re plugged in the cluster and it went away. Just today, about a week after fixing it the first time, the “No Bus” check engine light came back on. Any ideas on what the problem is and how to fix it? Thanks

Mine says no bus when the computer is disconnected. Might check those connections and the grounds.
