I'm pretty sure it means the connector on the back of the IC is loose or dirty. Not sure what you need to put in search, but it has been discussed plenty. JIM.

Instrument Cluster
typical 97+ issue. pull the dash piece, unscrew the cluster, throw some di-electric grease in there and check the connections.

Do you have a "no-start" condition when you get the "NO BUS"? If you do, then the crank sensor (CPS/CKP) is shorted to ground.

There are 2 situations with NO BUS showing on the cluster
1. NO BUS shows and the engine runs fine
2. NO BUS shows and the engine does NOT run
As mentioned above, if the engine runs when you see this, it is a cluster connection issue.
And if the engine does NOT run, it usually means that one of the 5 volt engine management sensors is shorted. 99% of the time, as Joe mentions, it is the crankshaft position sensor.
