needs to be reset as follow:
Ö
Power on the main control box. Make sure no other main control boxes are working nearby.
Ö
Power on the display, press the wireless ID code setting button on the bottom of the display with a small flat
head screw driver until you hear one beep followed by two beeps indicating the display is set successfully.
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 the brake is applied, 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.
Obstacle surfaces absorbing ultrasonic wave such as human body and clothes will reduce the detection
distance of the system. 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.

Beeper switched off.
Faulty display.

Switch on the beeper.
Replace the display.
Replace the main control box.
Wrong LEDs light up
Sensors are plugged into
the wrong sockets at the
main control box
Install the sensors under the bumper as labeled
in Fig. 1 and plug sensors as labeled on the
sensor wires into their corresponding sockets at
the main control box
Display constantly shows
0.0 or beeps continuously
Object within 1ft (0.30m) is
detected.
Faulty sensors.
Unplug all sensors, and then plug back in one
sensor at a time to find out which sensor is
causing the problem. Adjust position or angle of
the sensor. Refer to
5. Installation of the
Sensors
for details.
Display shows a distance
and beeps even there is no
obstacle behind
Ground is detected.
Sensor is angled too low.
Sensors are installed too
low (mounting height
below 1.6ft or 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 position or angle of
the sensor. Refer to
5. Installation of the
Sensors
for details.
