Warning
z
To avoid collision with obstacle because of the inertia of vehicle while backing up/parking, keep your vehicle
speed at about
3 miles per hour
and stop the vehicle immediately once you hear the continuous beeping.
This is because even if you have applied brake, your vehicle will still go for some distance (inertia) before it
comes to a complete stop.
z
Because the back up parking system detects obstacle by emitting ultrasonic wave and receiving reflected
ultrasonic wave from obstacle, the system may fail to give both visual and audible alert if an obstacle has
smooth ball-shaped or sloped surfaces as such surfaces may not reflect ultrasonic wave back to the sensors.
Drivers in these situations should pay more attention while parking their vehicles.
z
In heavy falling rain or snow, the system may give alert as falling rain or snow may be detected as obstacles.
Keep surface of sensors clean of snow, mud, dirt, and other debris.

System is not detecting any
obstacle in front
No control signal from brake.
Check main control box connection to
+12V from brake.
System is not detecting any
obstacle in rear
No control signal from back up
light.

Wrong LEDs light up
Sensors are plugged into the
wrong sockets at the main
control box
Install the sensors in the bumper as
labeled in Fig. 1 & 2 and plug sensors as
labeled on the sensor wires into their
corresponding sockets at the main control
box (Fig. 3)
Display constantly shows 0.0
or beeps continuously
Object within 0.40m is detected
Unplug all sensors, and then plug back in
one sensor at a time to find out which
sensor is causing the problem. Adjust
angle of the sensor. Refer to
4.

Display shows a distance
and beeps even there is no
obstacle behind
Ground is detected.
Sensors angle is low.
Sensors installed too low
(mounting height below 0.5m)
Unplug all sensors, and then plug back in
one sensor at a time to find out which
sensor is causing the problem. Adjust
angle of the sensor. Refer to
