Operation Check

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

1. CHECK INITIAL CHECK FUNCTION

(a) Check the initial check function for the buzzer.





(1) When the back sonar or clearance sonar switch assembly is turned on, check that the following occurs: 1) after 0.2 seconds, the buzzer sounds for approximately 0.7 to 1.3 seconds, and 2) the system starts the obstacle detection operation.

(b) Check the initial check function for the sensor.

Approximately 0.2 seconds after the ignition switch is turned to ON and the back sonar or clearance sonar switch is turned on, all the sensors are checked by the system.

When the shift lever is operated, the system starts the obstacle detection operation.

(c) If a sensor is found to have an anomaly due to an open circuit, the buzzer sounds after the initial check function is completed to inform the driver and indicate which sensor is abnormal.

(1) When the ECU determines that the sensor needs to be repaired or cleaned:





(2) When the ECU determines that the sensor needs to be cleaned:





HINT
* When the sensor condition returns to normal, the system ends normal clearance sonar mode and returns to steering sensing mode.
* If the clearance sonar switch is on and the ignition switch is turned to ON, the buzzer does not sound.

2. DETECTION RANGE MEASUREMENT AND INDICATOR CHECK

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

(a) Turn the ignition switch to ON.

(b) Turn the back sonar or clearance sonar switch on.

(c) Move the shift lever to R to check the rear corner sensors and rear center sensors.

(d) Move a pole around the sensor to measure the detection range of the sensor.

NOTICE:
* These detection ranges are applicable when positioning a pole with a diameter of dia60 mm (2.36 in.) 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 No. 1 ultrasonic sensor side view detection range hatched area*1 represents the cross section of the top view of the detection range along the lines labeled A. The hatched area*1 does not represent the entire side view detection range.

(1) Rear corner sensor detection range





(2) Ultrasonic sensor detection range





(e) When the ultrasonic sensors detect an obstacle with the back sonar or clearance sonar switch on, check that the buzzer sounds.

Operation Condition





(1) Check that the buzzer sounds with the back sonar or clearance sonar switch on.





Rear Corner Detection Range





Rear Center Detection Range





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

(2) Check the indicator and buzzer when the back sensors and rear corner sensors have detected an obstacle.
