DYNAMIC RADAR CRUISE CONTROL SYSTEM FAIL-SAFE CHART


  1. Tech Tips

    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.

    Automatic Cancel Control

    Constant Speed Control Mode:
    Auto Cancel Condition Warning Fail-safe Deactivation Condition
    Multi-information Display Master Warning Light Cruise Control Indicator Warning Buzzer
    Open or short in stop light switch circuit Check Cruise Control System Visit Your Dealer Illuminates Does not illuminate Sounds Dynamic radar cruise control system is turned off and back on again using the cruise control main switch (ON/OFF button).

    • Problem with stop light switch input circuit

    • Problem with cruise control main switch cancel circuit

    • Malfunction in the electronically controlled brake system

    • Communication stop between skid control ECU and hybrid vehicle control ECU

    		 Check Cruise Control System Visit Your Dealer Illuminates Does not illuminate Sounds Power switch is turned off and back to on (IG) again.

    If the following condition occurs, the hybrid vehicle control ECU cancels control of vehicle speed by the dynamic radar cruise control system (stored vehicle speed is maintained):


    • Vehicle speed is less than approximately 40 km/h (25 mph) while driving with the dynamic radar cruise control system controlling vehicle speed

    		 - Does not illuminate Illuminates - Cruise control main switch is pushed to +RES
    Malfunction in hybrid control system Cruise Control not Available Illuminates Does not illuminate - Dynamic radar cruise control system is turned off and back on again using the cruise control main switch (ON/OFF button).
    Vehicle speed is less than stored vehicle speed by approximately 16 km/h (10 mph) or more - Does not illuminate Illuminates - Cruise control main switch is pushed to -SET

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

    • TRC system operates for a certain period of time while driving with dynamic radar cruise control system controlling vehicle speed.

    • TRC is turned off

    • VSC is turned off

    • Drive start control is performed

    • Parking brake is applied

    		 - Does not illuminate Illuminates - Cruise control main switch is pushed to +RES
    Vehicle-to-vehicle Distance Control Mode:
    Auto Cancel Condition Warning Fail-safe Deactivation Condition
    Multi-information Display Master Warning Light Cruise Control Indicator Warning Buzzer
    Open or short in stop light switch circuit Check Cruise Control System Visit Your Dealer Illuminates Does not illuminate Sounds Dynamic radar cruise control system is turned off and back on again using the cruise control main switch (ON/OFF button).
    Malfunction in hybrid control system Cruise Control not Available Illuminates Does not illuminate - Dynamic radar cruise control system is turned off and back on again using the cruise control main switch (ON/OFF button).

    If either of the following conditions occurs, the hybrid vehicle control ECU cancels control of vehicle speed by the dynamic radar cruise control system (stored vehicle speed is maintained):


    • Vehicle speed is less than approximately 40 km/h (25 mph) while driving with the dynamic radar cruise control system controlling vehicle speed

    • A preceding vehicle is not detected when follow-up control is being performed at a vehicle speed of approximately 40 km/h (25 mph) or less*

    		 - Does not illuminate Illuminates - Cruise control main switch is pushed to +RES

    • Malfunction in the millimeter wave radar sensor assembly

    • Beam axis of millimeter wave radar sensor assembly misaligned

    • Problem with stop light switch input circuit

    • Problem with cruise control main switch cancel circuit

    		 Check Cruise Control System Visit Your Dealer Illuminates Does not illuminate Sounds Power switch is turned off and back to on (IG) again.

    If the following condition occurs, the hybrid vehicle control ECU cancels control of vehicle speed by the dynamic radar cruise control system (stored vehicle speed is maintained):


    • Millimeter wave radar sensor assembly becomes dirty

    		 Clean Radar Sensor Illuminates Does not illuminate Sounds The condition returns to normal (the resume function can be operated after fail-safe is deactivated).

    If any of the conditions listed below occurs, the hybrid vehicle control ECU cancels control of vehicle speed by the dynamic radar cruise control system (stored vehicle speed is maintained):


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

    • Brake control by the dynamic radar cruise control system is temporarily unavailable

    • The beam axis of the millimeter wave radar sensor assembly is being aligned

    • The forward recognition camera is temporarily unavailable

    • A system check is being performed after the engine has started

    		 Cruise Control not Available Illuminates Does not illuminate Sounds The conditions return to normal (the resume function can be operated after fail-safe is deactivated).

    • TRC system operates for a certain period of time while driving with cruise control system controlling vehicle speed.

    • TRC is turned off

    • VSC is turned off

    • Drive start control is performed

    • Parking brake is applied*

    		 - Does not illuminate Illuminates - Cruise control main switch is pushed to +RES

    If any of the following conditions occur while the vehicle stopped, the hybrid vehicle control ECU cancels control of vehicle speed by the dynamic radar cruise control system*:


    • Open or short in stop light switch circuit

    • Malfunction in the millimeter wave radar sensor assembly

    • Beam axis of millimeter wave radar sensor assembly misaligned

    • Problem with stop light switch input circuit

    • Problem with cruise control main switch cancel circuit

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

    • Millimeter wave radar sensor assembly becomes dirty

    • Brake control by the dynamic radar cruise control system is temporarily unavailable

    • The beam axis of the millimeter wave radar sensor assembly is being aligned

    • The forward recognition camera is temporarily unavailable

    • A system check is being performed after the engine has started

    		 Check Cruise Control System Depress the Brake Pedal Visit Your Dealer Illuminates Does not illuminate 3 beeps are heard The conditions return to normal (the resume function can be operated after fail-safe is deactivated).

    If any of the following conditions occur while the vehicle stopped, the hybrid vehicle control ECU cancels control of vehicle speed by the dynamic radar cruise control system*:


    • The driver seat belt is unfastened

    • The driver door is opened

    • The vehicle is parked for a long period of time

    • The vehicle is driving on a steep hill

    • A preceding vehicle is not detected

    		 Cruise Control Off. Shifted to [P] Position. Depress the Brake Pedal and Shift to [D] to Restart Does not illuminate Illuminates - The conditions return to normal (the resume function can be operated after fail-safe is deactivated).
