07-3 PAS (PARKING AID SYSTEM) korando 2010.10 8790-01 8790-04 PAS 1. SPECIFICATION Description Specification Description Specification Rated voltage DC 12.0 V Insulation resistance No heat & fire due to current leak Operating voltage DC 9.0 V to 16.0 V Maximum permissible current Unit: below 100 mA Operating temperature -30℃ to +80℃ Sensor: below 20 mA Storage temperature -40℃ to +85℃ Weight Unit: 75.7 g ± 5 g Maximum humidity 95% Sensor: 38.7 g ± 5 g 2. CAUTIONS Sensor Cannot Detect ▶ When the sensing portion is frozen. When the sensing portion is covered by rain, water drops, snow or mud. - - Not defective but improperly working ▶ When driving on rough roads, gravel roads, hills, or grass. When the bumper height is changed due to a heavy load. When receiving other ultrasonic signals (metal sounds or air braking noises from heavy commercial vehicles). When a high-power radio is turned on. When there is heavy rainfall or water drops. When the sensor is hindered by improperly fitted accessories. - - - - - - Certain obstacles that sensors cannot detect ▶ Thin and narrow objects, such as wires, ropes, or chains Cotton, sponge, clothes, snow that absorb ultrasonic waves. Obstacles lower than the bumper: Drainage or puddle - - - Weak Sensing Scopes ▶ When they are partially covered by snow or mud. When the ambient temperature is too high or too low. - -

07-4 korando 2010.10 8790-01 PAS (PARKING AID SYSTEM) When the gear selector lever is shifted into “R”, the parking aid system is activated and three sensors in the rear bumper detect the distance to any obstacle. Driver can figure out the distance from the obstacle to the vehicle by the alarming sound. The alarm interval becomes faster as the vehicle approaches the obstacle. 1. OVERVIEW Buzzer for PAS Buzzer sounds according to the distance Gear select lever

07-6 korando 2010.10 8790-01 PAS (PARKING AID SYSTEM) 3. OPERATING PROCESS 1) Block Diagram When PAS receives "R" signal, it starts to detect the obstacles behind vehicle after self diagnosis. If the system detects the obstacle, the buzzer sounds according to the distance.

07-7 PAS (PARKING AID SYSTEM) korando 2010.10 8790-01 1st area: two beeps with long interval 2nd area: three beeps with short interval 3rd area: one long beep Sensing distance Area in 20 cm from bumper (Objects may not be detected in this range.) Alarm interval ▶ 2) PAS Sensor

07-9 PAS (PARKING AID SYSTEM) korando 2010.10 8790-01 Sensor operating sequence ▶ The ultrasonic sensors on the rear bumper transmit ultrasonic waves and receive the reflected waves from an obstacle to detect it. The left sensor transmits the signal first, then the center sensor, and then the right sensor.

07-10 korando 2010.10 8790-01 PAS (PARKING AID SYSTEM) 4. ALARM FOR SELF DIAGNOSIS Only when there is no obstacle within 30 cm from bumper 1. Open circuit in signal line 2. Open circuit in power line (+, -) - Fail conditions ▶ Alarm interval for self diagnosis ▶ When placing the gear select lever to "R" position, the self diagnosis is performed once. If it detects the Fail condition due to sensor defect or communication error, the buzzer sounds as shown in the picture. If the system is OK, the buzzer sounds for 65 ms.
