FAIL-SAFE FUNCTION
When communication fails in any of the CAN bus wires (communication wires), a fail-safe function(s) operates. The fail-safe function that is specified for each system operates to prevent those systems from malfunctioning.
Effects each system when communication is impossible (for further details, see the pages for each system).
