Operation Check
PARK ASSIST / MONITORING: INTUITIVE PARKING ASSIST SYSTEM: OPERATION CHECK
1. SELF-CHECK FUNCTION INSPECTION (INITIAL CHECK)
(a) Turn the power switch on (IG).
(b) Turn the intuitive parking assist system off, or check that the intuitive parking assist system is off.
(c) Turn the power switch off.
(d) Turn the power switch on (IG).
(e) Turn the intuitive parking assist system on, and check that the following occurs:
1) After approximately 0.1 seconds, the buzzer sounds for approximately 1 second.
2) The system starts detection operation mode.
HINT
* During the initial check, the malfunction detection operates and obstacle detection does not operate.
* In detection operation mode, obstacle detection and malfunction detection operate.
* 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, and the buzzer sounds.
* If the power switch is turned on (IG) while the intuitive parking assist system is on, the buzzer does not sound even though malfunction detection operates.

2. MALFUNCTION DISPLAY (MULTI-INFORMATION DISPLAY)
(a) Open circuit indication
(1) If there is an open circuit between the ultrasonic sensor and the clearance warning ECU assembly 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, check for DTCs and troubleshoot according to each inspection procedure Intuitive Parking Assist System.
(b) Frozen indication
(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 ultrasonic sensor (front left sensor) is covered with foreign matter.
* If "CLEAN SONAR" is displayed, refer to "Frozen indication is displayed in self-check function" on the Problem Symptoms Table to inspect it Intuitive Parking Assist System.
3. MALFUNCTION DISPLAY (MULTI-DISPLAY)
(a) Ultrasonic sensor open circuit
(1) If there is an open circuit between the ultrasonic sensor and the clearance warning ECU assembly 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.
(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 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
(a) Detection range measurement:
NOTICE:
Make sure that the vehicle does not move by applying the parking brake firmly.
(1) Turn the power switch on (READY).
(2) Move the shift lever to R to check the ultrasonic sensors.
(b) Turn the intuitive parking assist system on.
(c) Move a 60 mm (2.36 in.) diameter pole near each sensor to measure its detection range.
NOTICE:
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).
HINT
Have an assistant move the pole.
(1) Clearance Sonar
NOTICE:
The No. 1 ultrasonic sensor side view detection range 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
(d) When the ultrasonic sensors (front corner sonar) have detected an obstacle, check the displays and check that the buzzer sounds.
Operation Condition
Standard:
Multi-information Display and Buzzer
Multi-display and Buzzer
*5: When a shift state other than park (P) or reverse (R) has been selected
HINT
Ultrasonic waves are used to measure the detection range; however, the detection range may vary depending on the ambient temperature.
(e) When the ultrasonic sensors (rear corner sonar) have detected an obstacle, check the displays and check that the buzzer sounds.
Operation Condition
Standard:
Multi-information Display and Buzzer
Multi-display and Buzzer
HINT
Ultrasonic waves are used to measure the detection range; however, the detection range may vary depending on the ambient temperature.
(f) When the ultrasonic sensors (back sonar) have detected an obstacle, check the displays and check that the buzzer sounds.
Operation Condition
Standard:
Multi-information Display and Buzzer
Multi-display and Buzzer
HINT
Ultrasonic waves are used to measure the detection range; however, the detection range may vary depending on the ambient temperature.
