Operation Check
PARK ASSIST / MONITORING: INTUITIVE PARKING ASSIST SYSTEM: OPERATION CHECK
OPERATION CHECK
1. SELF-CHECK FUNCTION INSPECTION
(a) Turn the engine switch on (IG).
(b) When the intuitive parking assist system is turned ON, check that the following occurs: 1) after 0.1 milliseconds, the buzzer sounds for approximately 0.8 seconds, and 2) the system starts the obstacle detection operation.
- If a sensor has an open circuit or a sensor's detection operation malfunctions because it is wet or frozen, a malfunction display is shown in the multi-information display or multi-display, and the buzzer sounds.
- When the sensor condition returns to normal, the system ends normal clearance sonar mode.
- If the clearance sonar main switch is ON and the engine switch is turned on (IG), the buzzer does not sound.
2. MALFUNCTION DISPLAY (MULTI-INFORMATION DISPLAY)
(a) Ultrasonic sensor open circuit
(1) If there is an open circuit between the ultrasonic sensor and the clearance warning ECU or a sensor is malfunctioning, the malfunction is displayed as shown in the illustration.
HINT:
- The example shows an open circuit in the ultrasonic sensor (front left sensor).
- If a sensor has an open circuit, refer to "open circuit is displayed during self-check function" on the Problem Symptoms Table to inspect it.
(b) 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 ultrasonic sensor (front left sensor) is covered with foreign matter.
- If "CLEAN SONAR" is displayed, cleaning the foreign matter from the sensor will return the sensor to normal.
3. MALFUNCTION DISPLAY (MULTI-DISPLAY)
(a) Ultrasonic sensor open circuit
(1) If there is an open circuit between the ultrasonic sensor and the clearance warning ECU or a sensor is malfunctioning, the malfunction is displayed as shown in the illustration.
HINT:
- This example shows an open circuit in the ultrasonic sensor (rear right sensor).
- If a sensor has an open circuit, refer to "open circuit is displayed during self-check function" on the Problem Symptoms Table to inspect it.
(b) 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 ultrasonic sensor (front left sensor) 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
(a) Detection range measurement
NOTE:
Make sure the vehicle does not move by applying the parking brake firmly.
(1) Turn the engine switch on (IG).
(2) Release the parking brake lever (M/T).
(3) Move the shift lever to reverse position to check the ultrasonic sensors (rear sensors).
(b) Turn the clearance sonar main switch ON.
(c) Move a dia 60 mm (2.36 in.) pole near each sensor to measure its detection range.
NOTICE:
- These detection ranges are applicable when positioning the dia 60 mm (2.36 in.) pole parallel or perpendicular to the ground. The ranges vary depending on the measuring method and type of obstacle (such as walls).
- The No. 1 ultrasonic sensor side view detection range's hatched area (labeled *1) represents the cross section of the top view detection range's A lines. The hatched area (*1) does not represent the entire side view detection range.
(d) When the ultrasonic sensors (front clearance sonar) have detected an obstacle, check the displays and buzzer sounds.
Operation condition (for A/T models):
Operation condition (for M/T models):
Standard:
Multi-information display (A/T models: shift lever position not in P, M/T models: Release the parking brake)
Multi-display (A/T models: shift lever position not in P, M/T models: Release the parking brake)
With rear view monitor (shift lever position R)
HINT:
- Ultrasonic waves are used to measure the detection range; however, the detection range may vary depending on the ambient temperature.
(e) When the ultrasonic sensors (back sonar) have detected an obstacle, check the display and buzzer sounds.
Operation condition:
Standard:
Multi-information display (shift lever position R)
Multi-display (shift lever position R)
With rear view monitor (shift lever position R)
HINT:
Ultrasonic waves are used to measure the detection range; however, the detection range may vary depending on the ambient temperature.
(f) When the ultrasonic sensors (rear clearance sonar) have detected an obstacle, check the display and buzzer sounds.
Operation condition:
Standard:
Multi-information display (shift lever position R)
Multi-display (shift lever position R)
With Rear view monitor (shift lever position R)
HINT:
Ultrasonic waves are used to measure the detection range; however, the detection range may vary depending on the ambient temperature.
