Operation Check

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

1. 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 Problem Symptoms Table to inspect it Intuitive Parking Assist System.

2. 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 (IG).

(2) Move the shift lever to R to check the ultrasonic sensors.

(b) Turn the clearance sonar main switch 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





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





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





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