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

    • A warning message "CHECK CRUISE CONTROL SYSTEM" is displayed

    • "E3" is displayed

    • "Pong" warning sound is heard

    • Open or short in stop light switch circuit

    • Malfunction in the hybrid vehicle control system

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

  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

    • A warning message "CHECK CRUISE CONTROL SYSTEM" is displayed

    • "E3" is displayed

    • "Pong" warning sound is heard

    • Problem with millimeter wave radar sensor

    • Beam axis of millimeter wave radar sensor deviates

    • Problem with stop light switch input circuit

    • Problem with cruise control switch cancel circuit

    • Electronically controlled brake system operates while driving with cruise control system controlling vehicle speed

    • Millimeter wave radar sensor or driving support ECU assembly country specification information malfunction

    • Communication stop between skid control ECU and driving support ECU assembly

    		 Power switch is turned off and back on (READY) again.

  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

    • A warning message "CLEAN RADAR SENSOR" is displayed

    • "E1" 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).

    • A warning message "CRUISE CONTROL NOT AVAILABLE" is displayed

    • "E2" is displayed

    • "Pong" warning sound is heard

    • Wipers operating on HI setting

    • 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 light on Vehicle speed is lower than stored 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 light on

    • Vehicle speed is lower than low speed limit (approximately 40 km/h (25 mph)) while driving with cruise control system controlling vehicle speed


    • Electronically controlled brake system operates while driving with cruise control system controlling vehicle speed

    		 Push the cruise control switch to +/RES
