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 main switch (ON/OFF).


    1. Inspect the SET function.


      1. A01XB9J

        Turn the dynamic radar cruise control system on using the cruise control main switch (ON/OFF).

      2. Check that the cruise control indicator is displayed in the multi-information display.

      3. Drive at a speed between approximately 50 km/h (or 30 mph) and 180 km/h (or 110 mph).

      4. Push the cruise control main switch to -/SET.

        Check that the cruise control indicator remains displayed, the cruise control SET indicator and set speed are displayed in the multi-information display.

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

    2. Inspect the + (ACCEL) function.


      1. A01XB26

        Turn the dynamic radar cruise control system on using the cruise control main switch (ON/OFF).

      2. Drive at a speed between approximately 50 km/h (or 30 mph) and 180 km/h (or 110 mph).

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

      4. Constant speed control mode:

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

        Vehicle-to-vehicle distance control mode:

        Check that the vehicle speed increases in increments of approximately 5 km/h (or 5 mph) while the cruise control main switch is pushed to +/RES and that the vehicle maintains the newly set speed when the switch is released.

      5. Push the cruise control main switch to +/RES and then release it immediately. Check that vehicle speed increases by approximately 1 km/h (or 1 mph) or 5 km/h (or 5 mph)* (tap-up control).

    3. Inspect the - (COAST) function.


      1. A01XB9J

        Turn the dynamic radar cruise control system on using the cruise control main switch (ON/OFF).

      2. Drive at a speed between approximately 50 km/h (or 30 mph) and 180 km/h (or 110 mph).

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

      4. Constant speed control mode:

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

        Vehicle-to-vehicle distance control mode:

        Check that the vehicle speed decreases in increments of approximately 5 km/h (or 5 mph) while the cruise control main switch is pushed to -/SET and that the vehicle maintains the newly set speed when the switch is released.

      5. Push the cruise control main switch to -/SET, and then release it immediately. Check that vehicle speed decreases by approximately 1 km/h (or 1 mph) or 5 km/h (or 5 mph)* (tap-down control).

    4. Inspect the CANCEL function.


      1. A01X80H

        Turn the dynamic radar cruise control system on using the cruise control main switch (ON/OFF).

      2. Drive at a speed between approximately 50 km/h (or 30 mph) and 180 km/h (or 110 mph).

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

      4. When any of the following are performed, check that dynamic radar cruise control system control of vehicle speed 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 or S to any other position.

        • Selecting the 3rd, 2nd, or 1st range with the shift lever in S.

        • Pulling the cruise control main switch to CANCEL.

        • Turning the dynamic radar cruise control system off using the cruise control main switch (ON/OFF). The stored vehicle speed in the ECM is not maintained.

    5. Inspect the RES (RESUME) function.


      1. A01XB26

        Turn the dynamic radar cruise control system on using the cruise control main switch (ON/OFF).

      2. Drive at a speed between approximately 50 km/h (or 30 mph) and 180 km/h (or 110 mph).

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

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

      5. After pushing the cruise control main switch to +/RES at a speed of more than approximately 50 km/h (or 30 mph), check that the vehicle resumes the speed set prior to cancellation and that the cruise control SET indicator comes on.

        Tech Tips

        The stored vehicle speed is retained even if vehicle speed drops below approximately 40 km/h (or 25 mph). The previously stored vehicle speed can be resumed by pushing the cruise control main switch to +/RES when the vehicle speed has returned to approximately 50 km/h (or 30 mph) or more.
