DYNAMIC RADAR CRUISE CONTROL SYSTEM FAIL-SAFE CHART


  1. Automatic Cancel Control

    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.

    Constant Speed Control Mode:
    Auto Cancel conditionSituation Warning Fail-safe Deactivation Condition
    Multi-information Display Master Warning Light Cruise Control Indicator Warning Buzzer
    Open or short in stop light switch circuit Cruise Control Malfunction Visit Your Dealer Illuminates Does not illuminate "Pong" warning sound is heard Dynamic radar cruise control system is turned off and back on again using the cruise control switch

    • Problem with stop light switch input circuit

    • Problem with cruise control switch cancel circuit

    • Malfunction in the vehicle stability control system

    • Communication stop between skid control ECU (brake actuator assembly) and ECM

    		 Cruise Control Malfunction Visit Your Dealer Illuminates Does not illuminate "Pong" warning sound is heard Ignition switch is turned off and back to ON again
    Malfunction in SFI system - Does not illuminate Illuminates - Dynamic radar cruise control system is turned off and back on again using the cruise control switch (ON/OFF)
    Vehicle speed is lower than stored speed by approximately 16 km/h (or 10 mph) or more - Does not illuminate Illuminates - cruise control switch is pushed to -/SET

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


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

    • Vehicle stability control 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.

    • VSC/TRC is turned off

    		 - Does not illuminate Illuminates - cruise control switch is pushed to +/RES

      for Manual Transaxle:

    • Engine speed rises to high-speed range

    • Engine speed drops to low-speed range

    • Dynamic radar cruise control system cannot determine current gear

    • 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

    • Malfunction in the forward recognition camera

    • The forward recognition camera is temporarily unavailable
