Desctiprion and operation

Description
ADAS_PRK is a unit that controls the functions required for ADAS parking. If the ADAS_PRK is applied, the parking distance warning function is also controlled by the ADAS_PRK.
System Function
Parking Collision-Avoidance Assist (PCA)
PCA is a parking safety system that assists in collision warning and emergency braking in the event of a collision with rear pedestrians and obstacles during reversing at low speed (collision warning is displayed on the instrument cluster and monitor and audible warning sounds)

Remote Smart Parking Assist (RSPA)
The Remote Smart Parking Assist (RSPA) uses the vehicle sensors to search the parking space. It is a convenient device that helps driver to park and to pull out the vehicle by automatically controlling the steering wheel, shifting and vehicle speed together with the various words of guidance and audible warning for parking.
System operating specifications
Parking Collision-Avoidance Assist

When reversing at a speed of below 10Kph
1.
When a collision risk is detected, visual/audible warnings are performed.
2.
When the collision risk increases, braking assistance is performed. (When braking mode is activated)
※ The braking deceleration value varies depending on the vehicle model and speed
3.
After braking assistance is completed: It releases the braking control after maintaining the braking power for a certain period of time.
Operating condition
1.
User Setting Menu (USM) : Driver assistance - select rear collision warning or braking warning
2.
When the reverse vehicle speed is below 10 Kph

The remote forward/reverse function can be used for the purpose of parking or pulling out the vehicle by moving a vehicle forward/reverse from outside the vehicle.
  
If the wheel alignment is bad, the Remote Smart Parking Assist function will not operate normally.
If the tire or wheel installed on the vehicle is replaced with a different sized product, the parking performance will be changed. So, replace with the same sized product when replacing.
System limitations
Parking Collision-Avoidance Assist (PCA)
User Setting Menu (USM) : Driver Assistance - If the rear collision warning or braking warning is not selected.
When gear is not positioned in 'R'.
When the reverse speed is over 10Kph
Remote Smart Parking Assist (RSPA)
When the parking space is curved or diagonal
When there is an obstacle (bicycle/motorcycle/shopping cart/trash can/narrow pillar etc.) near the parking space
When there is a circular pillar or narrow pillar, or a pillar surrounded by objects (structures) such as fire hydrants near the parking space.
If there is a bump or curbstones
When the vehicle is fitted with a snow chain, spare tire or wheel of different size
When tire pressure is lower or higher than the standard tire pressure
When the road is bumpy or slippery
Around the vehicle whose loading box is high or large vehicle such as truck, or when loading cargo that is longer or wider than the vehicle's length or width or when connecting a trailer
If the sensor is mounted or positioned incorrectly by an impact to the bumper due to accident
When parking on the slope
When wheel alignment is misaligned
When your vehicle is leaned severely to one side
When the parking distance warning sensor malfunctions or does not work (Refer to “Parking Distance Warning Function Operating Manual”)
When the battery of the smart key needs to be replaced
  
When the vehicle has been parked/stopped for a long time in a cold environment, the Remote Moving Forward/Backward may be delayed depending on the vehicle condition when the vehicle is turned ON remotely.
Remote Smart Parking Assist system may suddenly apply brake to avoid collision against stationary or moving object.
The Remote Smart Parking Assistant system may abnormally cancel parking when a person or animal passes around the vehicle.
Even if a search completion alarm sound is generated while searching for a parking space, there may be a case that search completion is canceled immediately depending on the surrounding environment.
When Remote Smart Parking Assistant system is operating, if there is any object within the blind-spot area of the sensor, a collision may occur.
When searching for a smart exit space, if there is an obstacle in the blind spot, the Remote Smart Parking Assistant system guides as it is possible to exit but you should park a vehicle manually as collision may occur.
If the object appears suddenly while Remote Smart Parking Assist system is operating, collision may occur.
If there is only a parking line without a target car in the parking lot, the Remote Smart Parking Assist system is unavailable.
Park and exit manually when you park on inclines.
When parking in a snowfall area, the detecting performance of the ultrasonic sensor may degrade depending on the amount of snowfall and the function may be cancelled if vehicle slips while searching for space or during parking.
When parking, the Remote Smart Parking Assist function is not supported for the safety reason on narrow roads narrower than the required minimum parking space (vehicle rotation radius) such as residential areas.
Remote Smart Parking Assist system does not support the diagonal parking.
Remote Smart Parking Assist system may be canceled when the vehicle slips or the vehicle could not move due to road condition such as pebbles or fragmented stones.
Performance of the Remote Smart Parking Assist system may be degraded if there is a circular pillar and narrow pillar or a pillar surrounded by objects such as fire hydrant.
When parked in a narrow space close to a wall or road, the smart exit function may not be supported normally.

Troubleshooting

Troubleshooting
Diagnosis with Diagnostic tool
1.
In the body electrical system, failure can be quickly diagnosed by using the vehicle diagnostic system (Diagnostic tool).
The diagnostic system (Diagnostic tool) provides the following information.
1)
Fault Code Searching : Checking failure and code number (DTC)
2)
Data Analysis : Checking the system input/output data state
3)
Actuation test : Checking the system operation condition
4)
S/W Management : Controlling other features including system option setting and zero point adjustment
2.
Connect the cable of Diagnostic tool to the data link connector in driver side crash pad lower panel, and turn on the Diagnostic tool.
3.
If diagnose the vehicle by Diagnostic tool, select "DTC Analysis" and "Vehicle".

4.
If check current status, select the "Data Analysis" .

5.
Select "ADAS_PRK", if you want to check current data of Driver parking assistance system.

Variant Coding Procedures
1.
Connect the cable of Diagnostic tool to the data link connector in driver side crash pad lower panel, and turn on the Diagnostic tool.
2.
Select the 'S/W Management' and 'Car model'.

3.
Select the 'Advanced Driver Assistance Systems_Parking' and Variant Coding.
