Chrysler Repair: 99 300m 3.5L: no bus but runs well

Question
I have replaced a computer and sensors and my Chrysler still showing no bus.  But car runs great

Answer
Hi Omero,
"No bus" may be referring to the lack of digital signals to the instrument cluster only. \
Is this "no bus" based upon what you see in the odometer window after doing the "on-off-on" routine or is it based on what is shown by a plug-in code reader?
Is the instrument cluster working properly at this time?
Have you tried disconnecting the battery briefly as this may be a "stale code" that needs to be erased?
Is there a history to this situation and which computer and which sensors have you replaced and why?
