CAN COMMUNICATION SYSTEM FAIL-SAFE CHART


  1. FAIL-SAFE FUNCTION


    1. When communication fails in any of the CAN bus lines (communication lines), a fail-safe function(s) will operate. The fail-safe function that is specified for each system operates to prevent those systems from malfunctioning.

    2. The following table shows the effects on each system when communication is impossible. (For further details, see the pages for each system.)

      Auto Operation

      (Automatically operates the active rear wing according to the driving mode [ECO mode and modes other than ECO mode]. Stores at 40 km/h [25 mph] and rises at 80 km/h [50 mph] [ECO mode] and 130 km/h [81 mph] [modes other than ECO mode])

      • Hybrid vehicle control ECU assembly


      • Communication lost with brake ECU (vehicle speed malfunction): if stopped, prohibits operation, if operating, prohibits operation after operation completes.

      • Communication lost with meter ECU (RSC ON/OFF switch signal): Maintains the RSC ON/OFF switch signal.

      • Communication lost with main body ECU (luggage signal): If operating, stops and prohibits operation. If stopped, prohibits operation.

      • Communication lost with ECM (communication lost with driving mode): Sets driving mode to any mode except Eco mode.
