Operation Check

PARK ASSIST / MONITORING: INTUITIVE PARKING ASSIST SYSTEM: OPERATION CHECK





1. CHECK INITIAL CHECK FUNCTION

(a) Turn the ignition switch to ON.

(b) 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 seconds

HINT
* If a malfunction is detected in the ultrasonic sensor circuits, the location of the malfunctioning sensor blinks on the displayed vehicle graphic. However, after the sensor returns to normal, the display also returns to normal.
* When the ignition switch is turned to ON while the clearance sonar main switch is on, the buzzer will not sound.

2. MALFUNCTION OF ACCESSORY METER ASSEMBLY

(a) 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.





HINT
* The example shows an open circuit in the No. 1 ultrasonic sensor (front left sensor).
* 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.

(b) 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
* The example shows that the No. 1 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 OF NAVIGATION RECEIVER ASSEMBLY

(a) 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.





HINT
* This example shows an open circuit in the No. 2 ultrasonic sensor (rear right sensor).
* 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.

(b) 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
* The example shows that the No. 1 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 CHECK

NOTICE:
Apply the parking brake securely so that the vehicle does not move.

(a) Turn the ignition switch to ON.

(b) Turn the clearance sonar main switch on.

(c) Move the shift lever to R to check the No. 1 ultrasonic sensors, No. 2 ultrasonic sensors and No. 3 ultrasonic sensors.

(d) Move the shift lever to D and N to check the No. 1 ultrasonic sensors.

(e) Move the dia60 mm (2.36 in.) pole around the sensor to measure the detection range of the sensor.

NOTICE:
* These detection ranges are applicable when positioning the dia60 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).
* 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.
* 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 sensor detection range





(2) No. 2 ultrasonic sensor detection range





(3) No. 3 ultrasonic sensor detection range





(f) When the ultrasonic sensors have detected an obstacle, check the navigation receiver assembly, accessory meter assembly and that the No. 1 clearance warning buzzer sounds with the clearance sonar main switch on.

Operation Condition





(1) Check that the buzzer sounds with the clearance sonar main switch on as shown in the illustration.





No. 1 Ultrasonic Sensor Detection Range





No. 2 Ultrasonic Sensor Detection Range





No. 3 Ultrasonic Sensor Detection Range





HINT
Ultrasonic waves are used to measure the detection range. However, the detection range may vary depending on the ambient temperature.

(2) When the No. 1 ultrasonic sensors have detected an obstacle, check the displays and buzzer sounds.

Operation Condition









Accessory Meter Assembly









Navigation Receiver Assembly





HINT
Ultrasonic waves are used to measure the detection range. However, the detection range may vary depending on the ambient temperature.

(3) When the No. 2 ultrasonic sensors and No. 3 ultrasonic sensors have detected an obstacle, check the displays and buzzer sounds.
