  1. Turn the ignition switch to ON.

    HINT:
    Wait 2 seconds after turning the ignition switch to ON.

  2. When the clearance sonar system is turned on, check that the following occurs: 1) after 0.4 milliseconds, the buzzer sounds for approximately 1 +- 0.3 seconds, and 2) the system starts the obstacle detection operation.

    HINT:
    1. If a sensor has an open circuit or a sensor's detection operation malfunctions because it is wet or frozen, a malfunction display is shown in the multi-information display, and the buzzer sounds.
    2. When the sensor condition returns to normal, the system ends normal clearance sonar mode.
    3. If the ignition switch is turned to ON after the clearance sonar main switch is turned on, the buzzer does not sound.

MALFUNCTION DISPLAY (MULTI-INFORMATION DISPLAY)


  1. Ultrasonic sensor open circuit



    1. If there is an open circuit between the ultrasonic sensor and the clearance warning ECU or if a sensor is malfunctioning, the malfunction is displayed as shown in the illustration.

      HINT:
      1. The example shows an open circuit in the ultrasonic sensor (front left sensor).
      2. If a sensor has an open circuit, a warning message will be displayed. In such a case, perform inspection according to the Problem Symptoms Table.


  2. Ultrasonic sensor frozen



    1. If a sensor is covered with foreign matter, such as mud or snow, the affected sensor is displayed as shown in the illustration.


      Camry. Acv40 Gsv40.Park Assist Monitoring.Toyota Parking Assist-Sensor System.Toyota Parking Assist-Sensor System Operation Check

      HINT:
      1. The example shows that the ultrasonic sensor (front left sensor) is covered with foreign matter.
      2. If a message indicating the necessity of cleaning a sonar sensor is displayed, removing the foreign matter from the sensor will return the sensor to normal.

DETECTION RANGE MEASUREMENT AND DISPLAY INSPECTION

  1. Detection range measurement

    NOTICE:
    Make sure that the parking brake is firmly applied to prevent the vehicle from moving.

    1. Turn the ignition switch to ON.

    2. Move the shift lever to the reverse position to check the ultrasonic sensors (rear sensors).

  2. Turn the clearance sonar main switch on.



  3. Move a φ 60 mm (2.36 in.) pole near each sensor to measure its detection range.



    1. Measure the clearance sonar's detection range.


      Camry. Acv40 Gsv40.Park Assist Monitoring.Toyota Parking Assist-Sensor System.Toyota Parking Assist-Sensor System Operation Check

      NOTICE:
      These detection ranges are applicable when positioning the φ 60 mm (2.36 in.) pole parallel or perpendicular to the ground. The ranges vary depending on the measuring method and type of obstacle (such as walls).


    2. Measure the back sonar's detection range.
