what is the last 7 digits of the vin?
these systems have nothing in common, so it is not as simple as identifying the common component.
the most common cause of this would be a faulty ignition switch so I would suggest starting here as it is inexpensive
if the ignition switch does not solve the problem, it would have to be a faulty module which is causing interference for other modules and taking other systems offline
to diagnose this, you would need to disconnect modules one by one until the problem went away - thus identifying the problem component.
based on what you have described the srs / airbag module would be the most likely issue, followed by the slip ring.
