Toyota Parking Assist-Sensor System -- Operation Check


Land Cruiser. Urj200, 202 Grj200 Vdj200.Park Assist Monitoring.Toyota Parking Assist-Sensor System.Toyota Parking Assist-Sensor System Operation Check

INITIAL CHECK FUNCTION

  1. Turn the engine switch on (IG).

  2. After 2 sec. or more have passed, turn the back sonar or clearance sonar switch assembly ON. Then check the buzzer sounding condition.

    Buzzer sounding:
    1 +/-0.3 sec.
    HINT:
    1. 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.
    2. When the engine switch is turned on (IG) while the back sonar or clearance sonar switch assembly is on, the buzzer will not sound.

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.


      Land Cruiser. Urj200, 202 Grj200 Vdj200.Park Assist Monitoring.Toyota Parking Assist-Sensor System.Toyota Parking Assist-Sensor System Operation Check

      HINT:
      1. The example shows an open circuit in the No. 1 ultrasonic sensor (FL sensor).
      2. If a sensor has an open circuit, "Check Sonar" is displayed. Refer to "open circuit in front sensor is displayed as a result or self-check" in 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.

      HINT:
      1. The example shows that the No. 1 ultrasonic sensor (FL sensor) is covered with foreign matter.
      2. If "Clean Sonar" is displayed, cleaning the foreign matter from the sensor will return the sensor to normal.

      HINT:
      1. This example shows an open circuit in the No. 2 ultrasonic sensor (RR sensor).
      2. If a sensor has an open circuit, refer to "open circuit in rear sensor is displayed as a result of self-check" in 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.

DETECTION RANGE MEASUREMENT AND DISPLAY CHECK
NOTICE:
Apply the parking brake securely so that the vehicle does not move.

  1. Turn the engine switch on (IG).

  2. Move the shift lever to R to check the No. 1 ultrasonic sensors.

  3. Move the shift lever to D and N to check the No. 1 ultrasonic sensors.

  4. Turn the back sonar or clearance sonar switch assembly on.



  5. Move the diameter of 60 mm (2.36 in.) pole around the sensor to measure the detection range of the sensor.

    NOTICE:
    1. These detection ranges are applicable when positioning the diameter of 60 mm (2.36 in.) pole parallel or perpendicular to the ground.
    2. The ranges vary depending on the measuring method and type of obstacle (such as walls).
    3. For close-range and medium-range detection, the values shown are for when using a pole with a diameter of 60 mm (2.36 in.). For long-range detection, the values shown are for when using walls.
    4. The detection range of the resin bumper and steel bumper are not the same, as their installation positions are slightly different.



    1. No. 1 ultrasonic sensors (FL, FR sensor) detection range
