Can Communication System (W/ Vsc) -- Fail-Safe Chart



FAIL-SAFE FUNCTION

  1. When communication fails in any of the main wires (communication lines) due to a short circuit or other causes, the fail-safe function, which is specified for each system, operates to prevent the system from malfunctioning.

  2. The table below shows the effects on each system when communication is impossible. For further details, refer to each system.
