Operation Check

  1. SELF-CHECK FUNCTION INSPECTION 
    Fig 1: Identifying Buzzer Sound Pattern

    1. Turn the engine switch on (IG).
    2. When the intuitive parking assist system is turned on, check that the following occurs: 1) after approximately 0.1 seconds, the buzzer sounds for 0.8 +/- 0.3 seconds, and 2) the system starts the obstacle detection operation.

      HINT: 

      • If a sensor has an open circuit or a sensor malfunctions because it is wet or frozen, a malfunction display is shown in the multi-information display or display and navigation module display, and the buzzer sounds.
      • When the sensor condition returns to normal, the system returns to normal clearance sonar mode.
      • If the satellite switch (clearance sonar main switch) is on and the engine switch is turned on (IG), the buzzer does not sound.
  2. 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 a sensor is malfunctioning, the malfunction is displayed as shown in the illustration.

        HINT: 

        • The example shows an open circuit in the ultrasonic sensor (front left sensor).
        • If a sensor has an open circuit, refer to "Open circuit is displayed during self-check function" 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.

        GTY263384Courtesy 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.
  3. MALFUNCTION DISPLAY (DISPLAY AND NAVIGATION MODULE DISPLAY) 
    1. Ultrasonic sensor open circuit
      1. If there is an open circuit between the ultrasonic sensor and the clearance warning ECU or a sensor is malfunctioning, the malfunction is displayed as shown in the illustration.

        HINT: 

        • This example shows an open circuit in the ultrasonic sensor (rear right sensor).
        • If a sensor has an open circuit, refer to "Open circuit is displayed during self-check function" on 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.

        GTY257689Courtesy 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
      NOTE:

      Make sure that 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 to check the ultrasonic sensors (rear sensors).
    2. Turn the satellite switch (clearance sonar main switch) on.
    3. Move a 60 mm (2.36 in.) diameter pole near each sensor to measure its detection range.
      NOTE:

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

      1. Clearance Sonar:
        Fig 6: Hatched Area & Detection Range A

        NOTE:

        The hatched area (labeled *1) represents the cross section of the top view of the lines of detection range A. The hatched area *1 does not represent the entire side view detection range.

      2. Back Sonar:
        Fig 7: Back Sonar

    4. When the ultrasonic sensors (front clearance sonar) have detected an obstacle, check the displays and buzzer sounds.
