OPERATION CHECK 1. CHECK INITIAL CHECK FUNCTION
(a) Check the initial check function for the sensor.
- Approximately 0.4 seconds after the ignition switch has been turned to
the ON position and the back sonar or clearance sonar switch assembly
has been turned ON, all sensors will be checked by the system.
- When the vehicle has been shifted from P, the system will change to the
obstacle detection operation according to the shift position.
- 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 approximately 5 seconds have elapsed. If one or more sensors are
anomalous, check operation for all of the sensors will continue (sensors
will continue transmitting).
2. 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:
- If "Parking Assist Malfunction" is displayed, refer to the Problem Symptoms Table to inspect the problem.

- Buzzer sounding is stopped after approximately 7.5 seconds elapsed.
(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:
- Check if any foreign matter is attached to the ultrasonic sensors and theirsurrounding areas

- Buzzer sounding is stopped after approximately 7.5 seconds elapsed.
- If "Clean Parking Assist sensor" is displayed, refer to the Problem Symptoms Table to inspect the problem.

3. DETECTION RANGE MEASUREMENT AND INDICATOR CHECK NOTICE:
Make sure that the vehicle does not move by applying the parking brake firmly.
(a) Turn the ignition switch to ON. (b) Move the shift lever to R to check the front corner sensors, rear corner sensors and back sensors.
(c) Move the shift lever to the D, S and N position to check the front corner sensors.
(d) Turn the back sonar or clearance sonar switch assembly ON. (e) Move a pole around the sensor to measure the detection range of the sensor.
NOTICE:
- 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, medium-range detection and long-range detection, the
values shown are for when using a pole with a diameter of 60 mm (2.36
in.). For longest-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.
(1) Front corner sensors detection range
 (2) Rear corner sensors detection range
 (3) Rear center sensors detection range
