Sensor operating sequence
▶
The ultrasonic sensors transmit ultrasonic waves
and receive the reflected waves from an obstacle
to detect it in the following order: L → C → R.

4. OUTPUT SPECIFICATIONS FOR SENSOR SELF-
DIAGNOSIS BUZZER SOUND
Fail condition (However, no obstacle should be within 30 cm)
1. The signal wire is open
2. The power wire (+ and -)is open
-
Conditions to "FAIL" in sensor diagnosis
▶
Buzzer interval during self diagnosis
▶
Timeout processing time for buzzer interval after measuring distance/self diagnosis: 600 ms
- If timeout is reached, the PAS returns to undetected condition.
Process while re-inputting
- After timeout, the process is performed normally if the signal required for display is received
from beginning to end. (not detectable if the signal is received in the midst of process)

Exception/error handling
▶
Self diagnosis is performed once when the ignition is switched on (gear shift lever in "R" position). If the
system is defective (Fail) due to open sensor or communication problem, the information for the failed
sensor is displayed as buzzer sound.
If it is normal, the warning buzzer sounds for 60 ms.
