SsangYong Actyon Sports II. Service manual - part 110

8790-01

1. COMPONENT SPECIFICATIONS

The PAS (parking aid system) emits the ultrasonic wave signals from the sensors on the rear bumper at 

a specific interval

and detects the reflected signals from obstacles when reversing. The alarm interval increases as the 

obstacle approaches.

This supplementary system is useful to measure the distance when parking.

Parking Aid Unit

▶

Parking Aid Sensor

▶

Detecting type: Ultrasonic wave (Piezo 

ceramic element)

Calculates the distance between the sensor 

and the object by calculating the return time of 

the emitted the ultrasonic wave
Frequency used: 50 KHz ± 1 KHz

Detection distance: 30 cm ~ 120 cm

(based on lineal distance between sensor and 

obstacle)
Tolerance: ± 10 cm

2. CAUTIONS

Note that the display does not show everything in the rear area. Always check nobody, especially 

animals and children, is behind the vehicle when parking or reversing.

If you can not properly check the vehicle behind, get out of the vehicle and then visually check it.

The parking aid system is just a supplemental device to help your parking.

Always keep the safety precautions.

Do not press or shock the sensors by hitting or using a high-pressure water gun while washing, 

since it may damage the sensors.

If the system is in normal operating condition, a short beep sounds when the shift lever is moved into 

"R" position with the ignition key "ON".

The parking aid system will not work or improperly work under following cases:

▶

1. Certain obstacles that sensors can not detect

Thin and narrow objects, such as wires, ropes, chains

Cotton, sponge, clothes, snow; that absorb ultrasonic waves

Obstacles lower than the bumper (ex. drain ditch or mud puddle)

-

-

-

2. Not defective but improperly working

When the sensing portion is frozen (operates normally after thawed)

When the sensing portion is covered by rain, water drops, snow or mud (operates normally after 

cleaned)

When receiving other ultrasonic signals (metal sound or air braking noises from heavy 

commercial vehicles)

When a high-power radio is turned on

-

-

-

-

3. Narrowed sensing area

When the sensing portion is partially covered by snow or mud (operates normally after cleaned)
Surrounding temperature of sensor is too high (approx. over 80°C) or too low (approx. 
below -30°C)

-

-

When driving on the rough roads, gravel road, hill and grass

When the bumper height is changed due to heavy load

When the sensing portion is frozen

When the sensing portion is covered by rain, water drops, snow or mud

When receiving other ultrasonic signals (metal sound or air braking noises from heavy 

commercial vehicles)

When a high-power radio is turned on

When some accessories are attached in detecting ranges

Parking Aid Unit

1. GENERAL INFORMATION

1) Components and Function

The parking aid system uses three piezoelectric 

ceramic sensors inside the rear bumper to 

measure the vertical and horizontal distances to 

the obstacles. The parking aid system has a 

separate unit that sends signal to the buzzer 

when reverse parking to notify the driver of the 

distance to obstacle. When placing the gear 
selector lever to “R" position, this unit activates

the sensor to measure the distance between the 

object and the bumper. The existing PAS unit 

displays the malfunctions using the LED when 

there are any defects in sending/receiving signal 

or the open circuit to sensor. On the other hand, 

the PAS unit of KORANDO SPORTS informs the 

malfunction of the relevant sensor using a 

buzzer.

2. ALARM INTERVAL

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.

1) Sensing Distance and Range

Sensor detection range

Within 20 cm from the ground (Intrinsically, supersonic wave sensors may not detect obstacles 

within 20 cm from the ground)(Area 1)

Obstacles may not be detected within 80 cm from the sensor(Area 2)

Sensor may not detect zone within 30 cm from the rear bumper (Area 3)
