What it means (plain English)
The computer systems in the vehicle are not talking to each other properly due to a software issue.
What the computer is actually seeing
The vehicle's control unit detects that the software version is not matching expected configurations, triggering this fault.
What a healthy reading looks like
Expected software version should match the configuration file; check for any version mismatches (i.e., software version 1.05 is required, but version 1.02 is found).
