DYNAMIC RADAR CRUISE CONTROL SYSTEM ROAD TEST


  1. PROBLEM SYMPTOM CONFIRMATION

    Tech Tips

    The dynamic radar cruise control system has 2 cruise control modes: constant speed control mode and vehicle-to-vehicle distance control mode.


    • Vehicle-to-vehicle distance control mode is selected by default when the dynamic radar cruise control system is turned on using the cruise control switch (ON/OFF button).

    • Operation of constant speed control mode is the same as that for a conventional cruise control system.


    1. A01VNV2C02
      *a ON/OFF
      *b -/SET

      Inspect the SET function.


      1. Turn the cruise control system on using the cruise control switch (ON/OFF button).

      2. Check that the cruise control indicator illuminates in the combination meter assembly.

      3. Drive at a speed between approximately 50 km/h (31 mph) and 170 km/h (106 mph).

        *1

        Cruise Control Indicator

        (Vehicle-to-vehicle distance control mode)
        *2 Cruise Control SET Indicator

        Push the cruise control switch to -/SET.

      5. Check that the cruise control indicator remains illuminated, the cruise control SET indicator illuminates on the combination meter assembly and the set speed is displayed on the multi-information display.

      6. After releasing the switch, check that the vehicle maintains the set speed.

    2. A01VMKAC01
      *a ON/OFF
      *b -/SET
      *c +/RES

      Inspect the + (ACCEL) function.


      1. Turn the cruise control system on using the cruise control switch (ON/OFF button).

      2. Drive at a speed between approximately 50 km/h (31 mph) and 170 km/h (106 mph).

      3. Push the cruise control switch to -/SET.

      4. Check that vehicle speed increases while the cruise control switch is pushed to +/RES, and that the vehicle maintains the newly set speed when the switch is released.

      5. Push the cruise control switch to +/RES and then release it immediately. Check that the vehicle speed increases* (tap-up control).

        Tech Tips

        *: Constant speed control mode: increases by approximately 1.6 km/h (1 mph); vehicle-to-vehicle distance control mode: increases by approximately 1 km/h (1 mph) or 5 km/h (3 mph) (differs depending on the country).

    3. A01VNV2C03
      *a ON/OFF
      *b -/SET

      Inspect the - (COAST) function.


      1. Turn the cruise control system on using the cruise control switch (ON/OFF button).

      2. Drive at a speed between approximately 50 km/h (31 mph) and 170 km/h (106 mph).

      3. Push the cruise control switch to -/SET.

      4. Check that vehicle speed decreases while the cruise control switch is pushed to -/SET, and that the vehicle maintains the newly set speed when the switch is released.

      5. Push the cruise control switch to -/SET, and then release it immediately. Check that the vehicle speed decreases* (tap-down control).

        Tech Tips

        *: Constant speed control mode: decreases by approximately 1.6 km/h (1 mph); vehicle-to-vehicle distance control mode: decreases by approximately 1 km/h (1 mph) or 5 km/h (3 mph) (differs depending on the country).

    4. A01VOEAC01
      *a ON/OFF
      *b -/SET
      *c CANCEL

      Inspect the CANCEL function.


      1. Turn the cruise control system on using the cruise control switch (ON/OFF button).

      2. Drive at a speed between approximately 50 km/h (31 mph) and 170 km/h (106 mph).

      3. Push the cruise control switch to -/SET.

      4. When any of the following are performed, check that control of vehicle speed by the dynamic radar cruise control system is canceled and that the normal driving mode (no control of vehicle speed by the dynamic radar cruise control system) resumes.


        • Depressing the brake pedal

        • Moving the shift lever from D to any other position

        • Selecting the 3rd, 2nd or 1st range using the shift paddle switch assembly with the shift lever in D.

        • Pulling the cruise control switch to CANCEL

        • Turning the cruise control system off using the cruise control switch (ON/OFF button).

        The stored vehicle speed in the driving support ECU assembly is not maintained.

    5. A01VNSTC01
      *a ON/OFF
      *b -/SET
      *c +/RES

      Inspect the RES (RESUME) function.


      1. Turn the cruise control system on using the cruise control switch (ON/OFF button).

      2. Drive at a speed between approximately 50 km/h (31 mph) and 170 km/h (106 mph).

      3. Push the cruise control switch to -/SET.

      4. Cancel control of vehicle speed by the dynamic radar cruise control system by performing any of the CANCEL functions (other than turning the dynamic radar cruise control system off using the cruise control switch (ON/OFF button).

      5. After pushing the cruise control switch to +/RES while driving the vehicle at a speed of more than approximately 40 km/h (25 mph), check that the vehicle resumes the speed set prior to cancellation and that the cruise control SET indicator illuminates.

        Tech Tips

        The stored vehicle speed is maintained even if vehicle speed drops below approximately 40 km/h (25 mph). The previously stored vehicle speed can be resumed by pushing the cruise control switch to +/RES when the vehicle speed has returned to approximately 40 km/h (25 mph) or more.
