Most scan tools cannot access communications networks or give you the information you need. This requires a specialized DRB scan tool that can access the modules that are working and identify the ones not communication. There are numerous modules on this network including ABS, Airbag, PCM. BCM, Instrument cluster, lighting modules, traction modules, etc, etc. You are not equipped to diagnose this properly.
