Parking Sensor System
●PRODUCT COMPOSITION
The system consists of 3 basic components (see Fig.1):
Electronic Control Unit (ECU)
Detection Units - Ultrasonic Sensors
Warning Unit
When the vehic le is placed in reverse, the warning unit
warns drivers of obstacles by sounding an alarm.
Note: The warning unit has a High/Low switch for volume
control.
●HOW TO USE
System Startup
Reverse Parking System
The system is fully automatic. It is active only when the
vehicle is placed in reverse.
At system power-up (Vehicle ignition on, in reverse), you
will hear a short, half-second ‘beep’.
Diagnostics
After the system is turned on, the Park-Pro HD will go into
a self diagnostic mode for three seconds.
If, after three seconds a sensor malfunction is detected,
the warning unit will warn you of a fault. The system will still
operate, but may not function normally. (See
troubleshooting section for explanation of diagnostics

 4
Parking Sensor System
function.)
Note: Sensors must be installed in order of serial number. If not, the
diagnostic function may reference the wrong sensor. See Fig .2.
Warning Mode
See Fig.3 for the three detection zones.
Audible Warning: System beeps when an obstacle
appears within the Warning zones, shown in Diagram 2.

Remark: When obstacles appear behind the 2 rear side sensors (serial
numbers 1 and 4), system doesn’t beep unless the obstacles are within
the Caution and Danger zones.
Warning Unit
This unit warns you with a built-in buzzer, enabling you to
know the warning zone and distance to the obstacle.
About detection
Obstac le detection may vary due to object size, shape,
density and environmental conditions. It is recommended to
thoroughly check the system sensitivity before use.
An unusual reflection angle of obstacles may cause an
incorrect or unusual detection warning.
Refer to Fig.4 below: Point A may not be detected due to unsatisfactory
reflection angle.

 6
Parking Sensor System
In Fig.5, detection may be variable due to object size, height and
density. Angled surfaces may give false distance measurements.
Various surface angles may be detected at varying distances on the
display.
Low obstacle standing before a tall one
As shown in Fig.6,
although
Obstacle Ta-b is
lower than the
sensors, Part Tb
will be detected
and warned first. As you approach these obstacles, the warnings may
vary in intensity.
Unusual condition of obstac le
Due to varying height, size, clothing type (absorption of signal), etc., A
PERSON MAY NOT BE DETECTED. This device is only a parking aid
and should never be solely relied upon for safely backing up a vehicle.
Always use caution during any vehicle operation.
Obstac les outside the detecting range
In Fig.7, Surface B will be detected, while
Surface A may never be detected.
Unusual road surface condition
When road surfaces are rough, the
system may output a warning signal.
See Fig.8.
Obstac les in blind zone
The blind zone covers a range of 22cm
(9”) behind the vehicle. Obstacles in the
blind zone will never be detected.
Therefore, it is normal if the warning unit
provides incorrect detection results. See
Fig.9.

Warning unit
Install the warning unit using supplied adhesive strip in a
location where the alarm can easily be heard by the driver of
the vehicle.
Powering up
For details, refer to “Powering up”on page 12.
Test
For details, refer to “Test the System”on page 13.
Note: Sensors and trunk harness connectors are serialized
and must be connected in position and order as shown in
Fig.2; otherwise the diagnostic function will reference the
wrong sensor.
Tips on Sensor Installation
Width of different vehicle models varies; it is very
important to choose the correct locations to install sensors.
Sensors need to be
installed with the “Up” mark
facing up as shown in Fig.13.
Sensor must be fully
inserted and fit flush to
bumper face.

 10
Parking Sensor System
Area behind sensor must be open and not contact sensor
body (bumper, mounting brackets, foam…etc .).
The face of the sensor should be perpendic ular to the
ground. If the bumper surface is angled, use the supplied
angled bezels to compensate.
Note: To use angled bezels, first, carefully remove bezel
from sensor. Snap correct angled bezel on sensor with bezel
angle in proper orientation.
Horizontal and vertical positioning
See Fig.14, “L”is the width of vehicle. L1 is the horizontal
distance between sensors (L1=16”±2”). For a wider
detection angle, locate side sensors closer to the lateral
sides of the vehicle. L2 is the height of sensors
(L2=25”±5”).
Installation steps
·Mark the positions of each sensor on bumper with a
marker to ensure proper location.
·Drill holes using the included hole saw. (An M2/.079”
drill bit can be used to drill pilot holes to aid in this
process.)
·Remove the burrs from the hole edge with a file.
·Insert the sensor cables into the holes made in
bumper according to serial number. Refer to Fig.2
IMPORTANT
Use correct hole saw. Sensors may not function
properly with holes that are too small or too large
in diameter.
Plastic bumpers require the 21.5mm hole saw.

 11
Parking Sensor System
Plastic bumpers do not require the rubber
sleeves included in kit.
Metal bumpers require the 24.5mm drill. Metal
bumpers require rubber sleeves installed before
installing sensors. (Note: The rubber sleeves
must be oriented with "UP " notation mounted
up).
Sensors can be re-painted to match the color of
your vehicle. Note: The painting layer must be
symmetrical and less than 0.1mm (.004 in.)
thick.
Under-Bumper Installation Steps
·Mark the positions of each sensor below the bumper
with a marker to ensure proper location.
·Mount brackets using the supplied hardware.
Note: Brackets must be mounted to ensure the center
axis of the sensor is parallel to the center line of the
vehicle and perpendicular to the ground.
·Insert the rubber sleeves into the brackets.
·Insert the sensor cables into the holes made in
bumper according to serial number. Refer to Fig.2
Powering Up
Power connections of reverse parking system

If a sensor is found defective during diagnostics, the system
will tell you its serial number by beeping per Diagram 4. If all
sensors are defective, the system will beep a solid tone for
1.5 seconds.
Ex. 1: in case sensor No. 3 is abnormal
When powered on, system beeps once for 0.5 second (signal for
diagnostics), then rapidly beeps 3 times (signal of sensor No. 3 that is
abnormal). This alert will continue each time the system is started until
the problem with sensor No. 3 is resolved.
Ex. 2: in case both sensors No. 2 and 4 are abnormal
When powered on, the system beeps once for 0.5 second, and then
rapidly beeps 2 times, you should power off the system and solve the
problem of sensor No.2. When you re-start the system, after the beep
of 0.5 second, the system will beep rapidly4 times, indicating a problem
with sensor No. 4.
