1. Check the initial check function for the LED and buzzer.
   
   

   1. When the clearance sonar main switch is turned ON, check that the following occurs: 1) after 0.4 seconds, the buzzer sounds for approximately 0.7 to 1.3 seconds, and 2) the system starts the obstacle detection operation.
      

2. Check the initial check function for the sensor.
   

   1. Approximately 0.4 seconds after the ignition switch has been turned to the ON position and the clearance sonar main switch has been turned ON, all sensors will be checked by the system.
      
   2. After 1 +/-0.3 seconds have elapsed, the check operation for all of the sensors will stop when a vehicle speed of over 10 km/h (6 mph) is detected.
      
   3. When the vehicle has been shifted from the P position, the system will change to the obstacle detection operation according to the shift position.
      
   4. If there are no changes in the conditions, such as those listed above (speed or shift position), the sensor check operation will be halted after 5 +/-1 second have elapsed. If one or more sensors are anomalous, check operation for all of the sensors will continue (sensors will continue transmitting).
      




3. If the sensor is found to have an anomaly due to an open circuit or freezing for approximately 5 seconds or more, indications as shown in the following illustration appear.
   
   

   
   
   

   1. When the ECU judges that the sensor needs to be repaired:
      

      
      
      
      
   
   
   

   2. When the ECU judges that the sensor needs to be cleaned:
      

      
      
      
      

      HINT:

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

NOTICE:

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

1. Turn the ignition switch ON.
   

2. Move the shift lever to the R position to check the front corner sensors, rear corner sensors and back sensors.
   

3. Move the shift lever to the D, S and N position to check the front corner sensors.
   

4. Turn the clearance sonar main switch ON.
   





5. Move a pole around the sensor to measure the detection range of the sensor.
   

   NOTICE:

   1. These detection ranges are applicable when positioning the pole parallel or perpendicular to the ground.
      
   2. The ranges vary depending on the measuring method and type of obstacle (such as walls).
      
   3. 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.).
      
   4. The detection range of the resin bumper and steel bumper are not the same, as their installation positions are slightly different.
      
   
   
   
   
   

   1. Front corner sensors detection range
      

      
      
      
      
   
   
   

   2. Rear corner sensors detection range
      

      
      
      
      
   
   
   

   3. Back sensors detection range
      

      
      
      
      




6. When the ultrasonic sensors have detected an obstacle, check the accessory meter and buzzer sounds with the clearance sonar main switch ON.
