Dual-Purpose Parking Assist System
(Front or Rear)

01
User Manual
The PTS is designed as a driver assistance
device, and should not be used as a substitute for
safe parking practices. The area into which the
vehicle is to be reversed must be constantly
monitored while parking.
The manufacturer and its distributors do not
guarantee or assume liability for collisions or
damages while reversing and braking the vehicle.
Parking Assist System (PTS) helps to provide
assistance when reversing and parking. Driving
skills such as slowing down, use of mirrors are
always essential.
This system is for vehicles with DC 9~27V
only.
This system should be installed by a
professional auto technician.
Route wiring harness away from heat source
and electrical components.
It is strongly recommended to check the
position of the sensors before the actual
drilling of the holes.
Perform a functional test after installation.

The PTS411M23 comes with 4-senor parking
system that can be used as a front or rear
ultrasonic distance monitoring device
(Dual-purpose). It electronically detects the area
in front or behind the vehicle while reversing and
driving forward.
If the system detects an obstacle, it will have
alerts with audible tones and visual warnings. It
assists the driver when parking and in
manoeuvring situation.
All the detachable sensors are waterproof and
can be easily changed. Combined with the
anti-interference and anti-false alert technology,
the system can detect obstacles in any weather
conditions and response quickly. The system has
intelligent detection, which is ideal for vehicles
with tow-bar or spare tire.
Each part of this system has passed the most
stringent test before releasing to the market. It is
reliable at a wide storage temperature range and
becomes very useful when you are parking at a
raining day, snowing day or at night etc. With the
help of parking assist system, you can enjoy a
comfortable, relaxed and safer parking
experience.

2 or 4-sensor automatic recognition
The parking system can be used as a 2-sensor
system when fitted on either the front or rear of
vehicle. When using as a 2-sensor system make
sure you connect the two sensor to either B&C
port or A&D port on the ECU (please refer to
page 28).
When fitting this system on the front of a vehicle,
we highly recommend purchasing a set of
sensor cable extensions.
These extend the supplied 2.3m sensor cable by
2.3m making the sensor cables 4.6m long.

Self-testing function
For Front System:
Once ACC on, the system will test all front sensor automotically.
If all sensor are working properly, the buzzer will not have alert.
If a damaged or defective sensor is detected, then then system will “Bi” 3 times for alarm.
Bi---Bi---Bi---
Notes:
• Once sensor(s) is (are) damaged or defective, the buzzer will “Bi” for 3 times to indicate the sensor
(s) is (are) damaged or defective.
• The system will not alarm when sensors (A&D), (B&C) are damaged/ defective as it will work as
2-sensor front system automatically.
• The locations of damaged/ defective sensor(s) number (E1~E4) will be shown on display.
After self-testing function, the system will continue working for 8 seconds (jumper position “1” in ECU)
or 20 seconds (jumper position “2” in ECU) when the vehicle is moving closer or away from the obstacle.

Please find a no obstacle place to activate this function.
1. With the ignition “ON”, press and release the foorbrake 10 times with 1 second intervals.
2. On the 10th times, hold the footbrake down , the buzzer will "Bi" once after 5 seconds, then has a
long "Bi" sound for 2 seconds after 3 seconds to complete the learning process.
Clear the learning function:
1. With the ignition “ON”, press and release the foorbrake 12 times with 1 second intervals.
2. On the 12th times, hold the footbrake down, the buzzer will "Bi" once after 5 seconds, then "Bi"
once again after 3 seconds to complete the clearing process.

Note:
• This function is valid and acievable only if all sensors are working properly.
• The above procedure must be carried out with 3 minutes of the ignition being switched on. If the
ignition has been on for over 3 minutes turn the ignition off and back on again.
• If you make a mistake while carrying out the above procedure, release the footbrake for 3 seocnds
to clear the system memory and then start the procedure again.
• If the vehicle does not have nudge bars or other protrusions, you do not need to use this function.
• Perform a functional test after learning function is set.

Please find a no obstacle place to activate this function.
1. With the ignition “ON”, change the gear from “N” to “R” for 10 times (each gear change must bewithin 1
second).
2. On the 10th times,leave the gear in “R” position, the buzzer will "Bi" once after 2 seconds, then has a long
"Bi" sound for 2 seconds after 3 seconds to complete the learning process.
3. When the learning function is activated, the system will ignore the tow-bar or spare wheel and only
detect behind the vehicle.
Clear the learning function:
1. With the ignition “ON”, change the gear from “N” to “R” for 12 times (each gear change must be within 1
second).
2. On the 12th times, leave the gear in “R” position , the buzzer will "Bi" once after 2 seconds, then "Bi" once
again after 2 seconds to complete the clearing process.
Note:
• This function is valid and acievable only if all sensors are working properly.
• If you make a mistake while carrying out the above procedure, leave the gear in “R” position
for 2 seocnds to clear the system memory and then start the procedure again.
• If the vehicle does not have tow-bar or spare wheel, you do not need to use this function.

Attention Sensor maintenance
After installation, please perform a functional
test before use
Heavy rain, dirty or damaged sensors may
cause in false alarm occasionally
Ensure that the self-testing procedure is
comple-ted and all sensors are are function
properly before using the system
False detection may occur in the following
situations:
Do not wash the sensor with a pressure
washer or scrub them forcibly.
Please wash car with low-pressure spray.
Please melt the snow with water when the
sensors are covered.
Please clean the sensors with cloth or
low-pressure spray when the sensors are
covered by dirt.

Notes:
For 2-sensor front sensor system, recommended to install 2
sensors on position E&H for the best performance.
On some vehicles, due to the number plates location or bumper
design, the distance between the centre of two sensors (L2) will
be greater, i.e. L2>60cm. The kit will still function, however the
detection of narrow objects i.e. posts will be reduced.

Troubleshooting
Make sure the wires connected properly
Make sure the vehicle is ACC ON
Make sure the reverse gear is selected (the
reversing light should be lighted on)
2. Damaged sensor detected
Make sure ALL sensors plugged into the
ECU correctly and tightly
Make sure no snow or dirt covered on the
sensor
Please check the sensor is damaged or not
3. False alarm
Make sure ALL sensors plugged into the
ECU in the correct position tightly
Please check if any of sensors detected the
ground
Please check if the rubber ring of the sensor
came out (if sensor comes with rubber ring)
4. Buzzer alarm sound is too low or too high
Press volume button to adjust the volume to
a suitable level.
5. Learning function is invalid
Sensor(s) is/are damaged
Make sure ALL sensors plugged into the
ECU correctly and tightly
Plug the certified sensors into the ECU and
performing a functional test again
Please email us at
[email protected] about the
problems with details
6. If the problem persists, please follow
For consumer: Please contact the nearby
dealer or customer service center
For installer/dealers:
Test the sensors with a certified ECU by
performing a functional test.
Replace another ECU and retest the
sensors
Functional test
Functional testing is
performed by holding a
wooden board (0.3
x1.0m/1x3.3ft) standing at
the front or rear of the car,
and drive the car forward
