the 'no bus' issue
Hi, new to forum,
04 dak 4.7 quad 4x4, no gauges, no crank, no voltage on most of sensors (can't get plug off cks yet).New Battery installed 6mts ago. Had same issue 3 weeks ago, disconnected and reconnected battery ,everything went back to normal. Will a bad Governor pressure sensor shut down the pcm? Getting 920, 921, 960, and 999 codes. help.

Welcome frdakota,
Hang on, those don't look like P**** codes, they look like instrument cluster codes.
920 - The instrument cluster is not receiving a vehicle speed message from the PCM.
921 - The instrument cluster is not receiving a distance pulse message from the PCM.
960 - The instrument cluster is not receiving a PRND21 message from the TCM.
999 - An error has been discovered.
Basically, check all connections on the cluster and at the PCM. It may be a bad PCM. The only real way to diagnose it is to hook up a DRB and see if you're picking up the speed/distance pulses from the PCM.
