3) CIRCUIT DESCRIPTION
(1) COMPONENT SPECIFICATIONS
The parking aid system emits the supersonic wave signals from the sensors on the rear
bumper with a specific interval and detects the reflected signals from obstacles while the gear
selector lever is in "R" position. The number of displaying bars is decreased and the
alarm interval becomes faster as the obstacle approaches. This supplementary system is to
secure the safety distance for parking.
A. Parking aid unit
Detecting type: Super sonic wave
Detecting distance: 25 ~ 120 cm (distance between sensor and obstacle)
B. Parking aid sensor
- Type: Piezo ceramic element
- Frequency: 40 KHz ± 2 KHz
- Detecting range (13.5 V)
· Horizontal: Min. 20° at 110 ± 5 cm
· Vertical: Min. 20° at 110 ± 5 cm
(2) ALARM INTERVAL
Alarm interval and display changes
according to the distance as below: While
reversing, if obstacles are within stage 1,
the warning beep sounds with long
intervals. If within stage 2, the warning
beep sounds with short intervals and if
within stage 3, the warning beep sounds
continuously.

(3) TROUBLESHOOTING OF SENSOR
When the shift lever is in the "R" position with the ignition switch on, the sensor is diagnosed
once (under normal condition, the buzzer sounds once). If found any failure due to open circuit
to sensor or communication error, buzzer sounds as below: However, if more than one sensor
are malfunctioning, warning buzzer sounds for 3 seconds.
