    Did you try communicating directly with the instrument cluster?

    do you have communication with any other control modules if not there might be a bad module that is taking out the can bus line you'll have to unplug one module at a time and check to see if comunication is restored you can also check the can bus high and low lines on the ob2 dlc connector
