DETAILED FLOW

1.

INTERVIEW FOR MALFUNCTION

Interview the conditions and environment when occurring any malfunction to the customer.

>> GO TO 2.

2.

SYMPTOM CHECK

• Check the symptom from the customer's information.
• Check if any malfunction occurs other than the malfunction interviewed from the customer.

>> GO TO 3.

3.

INSPECTION BEFORE DIAGNOSIS

Check the following conditions of the sensor.
• Check if the sonar sensor is not frozen.
• Check if snow, mud, or other foreign objects are not adhering to the sonar sensor.
• Check if there is no deformation, scratches, or other damage to the sonar sensor.
• Check if water has not accumulated in the sonar sensor.
Is the sensor condition normal?

YES

>> GO TO 4.

NO

>> Repair the sensor condition. GO TO 5.

SONAR SYSTEM

System Diagram

INFOID:0000000000935705

System Description

INFOID:0000000000935706

• The sonar sensor installed to the rear bumper detects obstacles around the bumper.
• The distance between a bumper and obstacles is informed to the driver with different frequency of buzzer.

Activation condition

The rear sensor activates and outputs the warning buzzer in the following conditions.
• Reverse signal ON (Power supply)
• Obstacle detection

Obstacle detection distance

• The sonar control unit controls the obstacle detection distance. The detection distance differs between the

corner sensor and the center sensor.

• Obstacle detection distance is indicated by a variable beep frequency.

Obstacle detection range image

NOTE:

• When an obstacle and distance of a bumper approach to less than 30 cm (11.8 in), a buzzer sound becomes consecutive sounds.

• The nearest sensor from the detected obstacle applies the buzzer output frequency if plural sensors detect any obstacle simulta-

neously.

Description

SONAR CONTROL UNIT

• The warning buzzer outputs by inputting the sensor signal from corner/center sensor. The

warning buzzer outputs the separated buzzer.

• When reverse signal is input, a power supply is input into sonar control unit.

CORNER/CENTER SENSOR

The obstacle distance is detected. The signal is transmitted to the sonar control unit.

BUZZER

The warning buzzer outputs with the signal from the sonar control unit.
