INTUITIVE PARKING ASSIST SYSTEM OPERATION CHECK

MALFUNCTION DISPLAY (MULTI-INFORMATION DISPLAY)

1. 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.

      

      Tech Tips

      • 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 Click here.

2. 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.

      

      Tech Tips

      • 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 Click here.

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.

2. Turn the 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).

   Tech Tips

   Have an assistant move the pole.

   1. Clearance Sonar

      Note

      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

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

   Operation Condition

   Engine Switch	Clearance Sonar Main Switch	Shift Lever Position	Vehicle Speed
   On (IG)	On	In any position other than P	Less than approximately 13 km/h (8.1 mph) if speed is increasing Less than approximately 9 km/h (5.6 mph) if speed is decreasing

   

   Tech Tips

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

   When the ultrasonic sensors (rear corner sonar) have detected an obstacle, check the displays and check that the buzzer sounds.

   Operation Condition

   Engine Switch	Clearance Sonar Main Switch	Shift Lever Position	Vehicle Speed
   On (IG)	On	R	-
