      Main Body ECU (Multiplex Network Body ECU) Sends the vehicle information signal to the clearance warning ECU assembly via CAN communication.

  2. METER DISPLAY OPERATION


    1. When the simple intelligent parking assist system is operating normally (no DTCs are stored) and the S-IPA switch is pressed, the display screen changes.

      Note

      It is not possible to select a display screen if all display conditions are not met. Refer to the display conditions for each screen.

      Tech Tips

      A buzzer sounds when the S-IPA switch is pressed and the screen changes.

      *e Point at Which Automatic Operation of the Steering Wheel Begins *f Point at Which the Vehicle Needs to Be Reversed
      *g Point at Which the Direction of the Vehicle Needs to Be Changed - -

      1. While keeping a distance of approximately 1 m (3.28 ft.) from the parking space, drive the vehicle at a vehicle speed of 30 km/h (19 mph) or less with drive (D) selected and stop the vehicle beside the center of the parking space.

      2. With the vehicle stopped, press the S-IPA switch to select parking assist mode. (The buzzer will then sound.)

        Tech Tips


        • Depending on the speed or angle of the vehicle, the size of the parking space, the distance to the parking space, or vehicles surrounding the parking space, detection of an empty parking space by the ultrasonic sensors may not be possible.

        • Depending on the surroundings, the ultrasonic sensors may not be able to detect a desired parking space.

      3. Following the guidance on the screen, drive the vehicle forward at a vehicle speed of 7 km/h (4 mph) or less. The S-IPA indicator light illuminates, the buzzer sounds and automatic operation of the steering wheel begins.

        Tech Tips

        The driver is required to operate the brakes to stop the vehicle.

      4. The buzzer sounds when the position at which the vehicle needs to be reversed is reached.

      5. Following the guidance on the screen, select reverse (R) and start reversing the vehicle at a vehicle speed of 7 km/h (4 mph) or less.

        Tech Tips

        When the vehicle reaches the point where the direction of the vehicle needs to be changed, the buzzer sounds. Following the guidance on the screen, stop the vehicle and move the vehicle forward or backward.

      6. When the vehicle reaches the desired parking position, the buzzer sounds, the S-IPA indicator light turns off and automatic operation of the steering wheel ends.

  4. PARALLEL PARKING MODE


    1. Parallel parking mode operation

      A003KPUC01
      *a Position Beside the Desired Parking Space *b Point at Which Automatic Operation of the Steering Wheel Begins

        Tech Tips


          It is possible that parallel parking mode may operate in the following situations. Follow the guidance on the screen.

        • The S-IPA switch is pressed when the vehicle has moved beyond the position just beside the desired parking space.

        • The S-IPA switch is pressed when the vehicle is still moving toward the position just beside the desired parking space.

        • The S-IPA switch is pressed while the vehicle is moving toward the point at which automatic operation of the steering wheel begins and with the shift status reverse (R) is selected.

      2. While keeping a distance of approximately 1 m (3.28 ft.) from the desired parking space and keeping the vehicle parallel to the parking space, drive the vehicle forward at a vehicle speed of 30 km/h (19 mph) or less. If the side ultrasonic sensors detect that the parking space is suitable, the message "Space Detected Go Forward" will be displayed on the screen.

        Tech Tips


        • Depending on the speed or angle of the vehicle, the size of the parking space, the distance to the parking space, or vehicles surrounding the parking space, detection of an empty parking space by the side ultrasonic sensors may not be possible.

        • Depending on the surroundings, the side ultrasonic sensors may not be able to detect a desired parking space.

      4. When the vehicle reaches the position at which departure is possible, the buzzer sounds, the S-IPA indicator light turns off and automatic operation of the steering wheel ends.

  6. COMMUNICATION SYSTEM OUTLINE


    1. CAN communication system


      1. The simple intelligent parking assist system uses CAN communication for data communications between the clearance warning ECU assembly and each ECU.

      2. If a problem occurs in the CAN communication line, the clearance warning ECU assembly outputs a CAN communication malfunction DTC. (To check, use the GTS.)

      3. If a CAN communication line malfunction DTC is output, repair the malfunction in the communication line and troubleshoot the simple intelligent parking assist system when data communication is normal.

      4. Since the CAN communication line has its own length and route, it cannot be repaired temporarily with a bypass wire, etc.
