Operation Check

  1. INITIAL CHECK FUNCTION 
    1. Turn the engine switch on (IG).
    2. After 2 seconds or more have passed, turn the clearance sonar main switch ON. Then check the buzzer sounding condition.

      Buzzer sounding: 

      1 +/-0.3 sec. 

      HINT:

      • If a malfunction is detected in the ultrasonic sensor circuits, the location of the malfunctioning sensor blinks on the display's vehicle graphic. However, after the sensor returns to normal, the display also returns to normal.
      • When the engine switch is turned on (IG) while the clearance sonar main switch is ON, the buzzer will not sound.

  2. MALFUNCTION OF MULTI-INFORMATION DISPLAY 
    1. Ultrasonic sensor open circuit
      1. If there is an open circuit between the ultrasonic sensor and the ECU or a sensor is malfunctioning, the malfunction is displayed as shown in the illustration.
      Fig 2: Malfunction Of Multi-Information Display - Ultrasonic Sensor Open Circuit

      HINT:

      • The example shows an open circuit in the No. 1 ultrasonic sensor (front left sensor).
      • If a sensor has an open circuit, "Check Park Sonar System" is displayed. Refer to "open circuit in front sensor is displayed as a result or self-check" on the Problem Symptoms Table to inspect it.
    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.
      Fig 3: Malfunction Of Multi-Information Display - Ultrasonic Sensor Frozen
      G04951811Courtesy of © TOYOTA, LICENSE AGREEMENT TMS1002

      HINT:

      • The example shows that the No. 1 ultrasonic sensor (front sensors) is frozen.
      • If "Clean Park Sonar" is displayed, cleaning the foreign matter from the sensor will return the sensor to normal.
  3. MALFUNCTION OF MULTI-DISPLAY 
    1. Ultrasonic sensor open circuit
      1. If there is an open circuit between the ultrasonic sensor and the ECU or a sensor is malfunctioning, the malfunction is displayed as shown in the illustration.
        Fig 4: Malfunction Of Multi-Information Display - Ultrasonic Sensor Open Circuit

        HINT:

        This example shows an open circuit in the No. 1 ultrasonic sensor (rear right sensor).

        • If a sensor has an open circuit, refer to PROBLEM SYMPTOMS TABLE  "open circuit in rear sensor is displayed as a result of self-check" on the Problem Symptoms Table to inspect it.
    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.

        G04951813Courtesy of © TOYOTA, LICENSE AGREEMENT TMS1002

        HINT:

        • The example shows that the ultrasonic sensor (front left sensor) is covered with foreign matter.
        • If "Clean sonar" is displayed, cleaning the foreign matter from the sensor will return the sensor to normal.
  4. DETECTION RANGE MEASUREMENT AND DISPLAY INSPECTION 
    1. Detection range measurement
      CAUTION: Make sure the vehicle does not move by applying the parking brake firmly.
      1. Turn the engine switch on (IG).
      2. Move the shift lever to R position to check the front side sensors, rear center sensors and rear corner sensors.
      3. Move the shift lever to D, S and N position to check front side sensors, front corner sensors and front center sensors.
    2. Turn the clearance sonar main switch ON.
    3. Move a 60 mm (2.36 in.) pole near each sensor to measure its detection range.
      1. Front center sensors detection range

      NOTE: These detection ranges are applicable when positioning the 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).
    4. When the ultrasonic sensors have detected an obstacle, check the multi-information display, multi-display and buzzer sounds with the clearance sonar main switch ON.
