Operation Check

1. INITIAL CHECK FUNCTION 
   1. Turn the power switch ON (IG).
   2. 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 sec. 

      HINT:

   • If a malfunction is detected in the ultrasonic sensor circuits, the location of the malfunctioning sensor blinks on the display's vehicle graphic. However, after the sensor returns to normal, the display also returns to normal.
   • When the power switch is turned ON (IG) while the clearance sonar main switch is ON, the buzzer will not sound.

2. MALFUNCTION OF MULTI-INFORMATION DISPLAY 
   1. 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 front corner No 1 ultrasonic sensor LH.
      • If a sensor has an open circuit, "Check Park Sonar System" is displayed. Refer to "open circuit in front sensor is displayed as a result or self-check" on the Problem Symptoms Table to inspect it.
   2. 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 front corner No 1 ultrasonic sensor LH is frozen.
   • If "Clean Park Sonar" is displayed, cleaning the foreign matter from the sensor will return the sensor to normal.
3. MALFUNCTION OF MULTI-DISPLAY 
   1. 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 rear corner No. 1 ultrasonic sensor RH.

         • If a sensor has an open circuit, refer to "open circuit in rear sensor is displayed as a result of self-check" on the Problem Symptoms Table to inspect it.
   2. 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 front corner No 1 ultrasonic sensor LH 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 
   NOTE: Make sure 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 position to check the front side sensors, rear center sensors and rear corner sensors.
   3. Move the shift lever to D, S and N position to check front side sensors, front corner sensors and front center sensors
   4. Turn the clearance sonar main switch ON.
   5. Move a pole around the sensor to measure the detection range of the sensor.
      NOTE:

      • These detection ranges are applicable when positioning the 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 a pole with a diameter of 400 mm (15.7 in.).
      • The detection range of the resin bumper and steel bumper are not the same, as their installation positions are slightly different.
