DYNAMIC RADAR CRUISE CONTROL SYSTEM FAIL-SAFE CHART


  1. Constant speed control mode and vehicle-to-vehicle distance control mode:

    If any of the following auto cancel conditions are detected while the dynamic radar cruise control system is controlling vehicle speed, the system clears the stored vehicle speed and cancels control of vehicle speed by the dynamic radar cruise control system.

    Vehicle Condition Auto Cancel Condition Fail-safe Deactivation Condition

    • Cruise control indicator goes off

    • A warning message "Check Cruise Control System" is displayed

    • "Pong" warning sound is heard*

    • Open or short in stop light switch circuit

    		 Cruise control system is turned off and back on again using the cruise control switch (ON/OFF button).

    • Cruise control indicator goes off

    • A warning message "Check Cruise Control System" is displayed

    • "Pong" warning sound is heard

    • Malfunction in the stop light switch input circuit

    • Malfunction in the cruise control switch cancel circuit

    		 Engine switch is turned off.
    Cruise control indicator goes off

    • Malfunction in the throttle position sensor and motor

    • Malfunction in the SFI system

    		 Cruise control system is turned off and back on again using the cruise control switch (ON/OFF button).

    • *: Only in vehicle-to-vehicle distance control mode

  2. Vehicle-to-vehicle distance control mode:

    If any of the following auto cancel conditions are detected while the dynamic radar cruise control system is controlling vehicle speed, the system clears the stored vehicle speed and cancels control of vehicle speed by the dynamic radar cruise control system.

    Vehicle Condition Auto Cancel Condition Fail-safe Deactivation Condition

    • Cruise control indicator goes off

    • A warning message "Check Cruise Control System" is displayed

    • "Pong" warning sound is heard

    • Malfunction in the millimeter wave radar sensor

    • Deviation of beam axis of millimeter wave radar sensor

    • Problem with stop light switch input circuit

    • Problem with cruise control switch cancel circuit

    • CAN communication error between dynamic radar cruise control system related sensors and ECUs*

    		 Engine switch is turned off and back on (IG) again.

    • *: For details, refer to CAN communication system section.

  3. Vehicle-to-vehicle distance control mode:

    If any of the following auto cancel conditions are detected while the dynamic radar cruise control system is controlling vehicle speed, the system maintains the stored vehicle speed in memory and cancels control of vehicle speed by the dynamic radar cruise control system.

    Vehicle Condition Auto Cancel Condition Fail-safe Deactivation Condition

    • Cruise control indicator goes off

    • A warning message "Clean Radar Sensor" is displayed

    • "Pong" warning sound is heard

    		 There is dirt on millimeter wave radar sensor Cruise control system is turned off and back on again using the cruise control switch (ON/OFF button).

    • Cruise control indicator goes off

    • A warning message "Cruise Control not available" is displayed

    • "Pong" warning sound is heard

    • Wipers operating on HI

    • Millimeter wave radar sensor sensitivity reduced because of bad weather such as rain, fog, snow, or sandstorm

  4. Constant speed control mode:

    If the following auto cancel condition is detected while the dynamic radar cruise control system is controlling vehicle speed, the system clears the stored vehicle speed and cancels control of vehicle speed by the dynamic radar cruise control system.

    Vehicle Condition Auto Cancel Condition Fail-safe Deactivation Condition
    Cruise control indicator is on Vehicle speed is lower than stored vehicle speed by approximately 16 km/h (10 mph) or more Cruise control switch is pushed -/SET

  5. Constant speed control mode and vehicle-to-vehicle distance control mode:

    If the following auto cancel condition is detected while the dynamic radar cruise control system is controlling vehicle speed, the system maintains the stored vehicle speed in memory and cancels control of vehicle speed by the dynamic radar cruise control system.

    Vehicle Condition Auto Cancel Condition Fail-safe Deactivation Condition
    Cruise control indicator is on Vehicle speed is lower than low speed limit (approximately 40 km/h (25 mph)) while driving with cruise control system controlling vehicle speed Push the cruise control switch to +/RES (approximately 40 km/h (25 mph) or more)
