How the System Works

The Parking Sensor System determines obstacle distance by measuring the time needed for the ultrasonic wave emitted by a sensor to reach an obstacle and for the sensor to receive the ultrasonic wave reflected from the obstacle. Given the speed of the ultrasonic wave, the system can then calculate and display the distance between the sensor and the obstacle.

To provide good coverage for both front and rear end of vehicle, the system comes with 8 sensors (4 front and 4 rear sensors). ♦ To have the look of factory installed system, the 8 sensors are in-bumper type (to be installed in the front and rear bumpers by drilling holes through the bumpers). ♦ Controlled by +12V from the back up light, the rear sensors are activated when the vehicle is put in reverse. ♦ Controlled by +12V from the brake light, the front sensors are activated when forward parking/driving with braking. ♦ It comes with a beeper (audible alert) which beeps faster as vehicle gets closer to obstacle and sounds continuously when vehicle is within 0.4m (1.3ft) from an obstacle.

Note:

♦ The front sensors will continue to work for 10 more seconds after brake is released. ♦ The system may beep once under the following conditions to let the driver know the system is activated and ready or

deactivated: (1) When vehicle is started or ACC is turned on or off (2) When vehicle is put in Reverse gear.

Tools Needed

Φ22.3mm (7/8") drill bit (include), drill, tape measure, chalk or marker, wire stripper, vinyl electrical tape, cable/wire ties, voltage meter or test light, screw driver set, pliers. Note: Use a bi-metal 22.3mm (7/8") drill bit (not included) if drilling through metal bumpers.

Installation and Wiring

IMPORTANT: (a) Read this manual thoroughly before proceeding to installation. You can also have the system installed by a professional installer such as your local auto mechanic/auto electrician/car stereo store. (b) Turn off the engine and ACC during installation. (c) Double check that all wiring is correct before powering on the system. (d) During installation, avoid flatting, perforating, cutting, and extending the wires of sensors to reduce unnecessary signal loss.

1. Installing the Control Box

a) Find a flat and clean surface for the control box inside the vehicle near the driver's side

taillight assembly. Note: To avoid possible interferences from the taillight assembly, keep the control box away from the taillight assembly for

at least 12”. As the control box is not

ater-proof type, you need to mount the control box to a location that is protected from water. Keep it away from areas of high heat, high humidity, direct sunlight, and electromagnetic devices.

b) Place the control box in place temporarily without securing it to the vehicle as you may need

to adjust the location of the control box while wiring. Note: After completing all wiring, use the double-sided self-adhesive pad (included) to secure it to the vehicle.

c) Insert the 5-pin plug of the power cable for the control box into its 5-pin socket labeled

"PWR" on the front side of the control box. See Fig. 4 for details.

Important Notes for Installing the Control Box:

Don't mount the control box near or under the dash or in the cab of a truck. The control box is designed to be mounted near the rear end of a vehicle to avoid interferences from the engine which may cause false alert such as continuous beeping.

If Installing the System to a Truck, as the control box is not water-proof type, you may need to first mount the control box in a small water-proof metal or plastic box (not included with the system), then fix it to a location near the rear end of the truck.

Note: Some lights (turn signal/brake/reverse/stop lights) may emit interferences that can affect the signals the control box receives therefore cause the system to give false alert. After installation, if you experience false alert caused by turn signal light, or brake/reverse/stop lights, try to put the control box as far as possible away (at least 12 inches) from the taillight assembly (turn signal/brake/reverse/stop lights).

Warnings

● 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.

● Because the 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.

● In 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.

2. Wiring the Control Box - Refer to Fig. 4 for the following wiring.

a) Locate the +12V wire from the back up light near the taillight assembly. If necessary, remove

the taillight assembly and use a voltage meter or test light to locate/verify it. The wire is easy to be identified/confirmed as it has +12V only when vehicle is in reverse. Strip 1/2" of the wire found. Connect the blue wire of the power cable to it. Wrap it with vinyl electrical tape.

b) Locate the (-) negative wire from the back up light near the taillight assembly. Or instead of (-)

negative wire from the back up light, you can also locate a chassis ground point near by. Strip 1/2" of the wire found. Connect the black wire of the power cable to it. Wrap it with vinyl electrical tape.

c) Locate the +12V wire from the brake light near the taillight assembly. If necessary, remove

the taillight assembly and use a voltage meter or test light to locate/verify it. The wire is easy to be identified/confirmed as it has +12V only when the brake is pressed. Strip 1/2" of the wire found. Connect the white wire of the power cable to it. Wrap it with vinyl electrical tape.

d) Under the dashboard, locate the ACC wire. It is easy to be identified/confirmed as it has

+12V only when the key of the vehicle is in the ACC position or the vehicle is running. The cigarette lighter on the front control panel is one of the ACC wires. Strip 1/2" of the wire found. Connect the red wire of the power cable to it. Wrap it with vinyl electrical tape.

3. Installing the Beeper

a) Find a place for the beeper near the middle or rear end of the vehicle on the driver side.

Place the beeper in place temporarily without securing it to the vehicle. Note: After completing all wiring, secure it with the included self-adhesive pad on the bottom of the rear beeper.

b) Hide the wire under the carpet or weather trim.

4. Installing the Sensors IMPORTANT: (a) To avoid false alert from the system detecting the ground, the sensors should

be mounted in the bumpers 50cm to 80cm (20" to 32") above the ground and the face of the sensors need to be vertical or slightly upward angled (Fig.3). (b) Horizontally, the sensors should be equally spaced if possible or symmetric to the center of the bumper (Fig.1 and 2). (c) The recommended mounting positions for the outer two sensors is about 15cm (5.9") from the corner of the bumper for better corner coverage (Fig.1 and 2).

Note: The bumper surface for mounting the sensors should be as flat and vertical as possible. The sensors come with wedged edge. Rotate the sensors to adjust for non-vertical bumper.

For exact color match, you may have the sensors spray-painted. For best results, spray paint no more than two thin coats (not to be applied with brush or touch-up). And it is recommended that you have the sensors professionally painted by an auto body shop. Note: although the sensors can be spray-painted for exact color match to your vehicle, sensors painted void warranty on them.

a) Refer to Fig. 1 and 2 for the recommended mounting height and position of the front and rear

sensors. You may need to make adjustments to them for your specific vehicle.

b) Work under the front and rear bumpers to check the internal structure of them before

marking the positions for drilling holes. Remove the bumpers if the view is blocked.

c) With chalk or marker, mark the position of sensors on the bumpers. Make sure that the

sensors can be pushed all the way in and that you can feed the wires through.

d) Drill the holes through the bumpers at the marks with the Φ22.3mm (7/8”) drill bit included.

Note: if drilling through metal bumper, you will need a bi-metal Φ22.3mm (7/8”) drill bit (not included).

e) If necessary, smooth the sharp edge of the holes with a polishing head or small round file. f) Run the sensor wires into the holes drilled. Push the sensors into the holes. When pushing

the sensors only apply pressure at the edges, not on the middle of the sensor to avoid damage to the sensor element. The sensors are tapered for a snug fit

g) Adjust the sensors for non-vertical bumper surface by rotating the sensors as needed.

h) For front sensors, run the sensor wires from the front bumper into the inside of the vehicle

through the existing wiring holes or rubber grommet in the fire wall, and then to the control box in the back of the vehicle (hide the wire under the door or weather trim). Note: Keep the sensor wires away from moving parts and engine heat.

i) For rear sensors, run the sensor wires from the rear bumper into the trunk or inside of the

vehicle through the existing small vent or rubber grommet in the rear of the trunk or vehicle, and then to the control box. Note: Do not cut the excess sensor wires to avoid signal loss. Sensors with wires cut also void their warranty.

j) Attach sensor wires to the vehicle body with cable/wire ties so that they will not get in the

way of any moving parts and there are no loose wires hanging down.

k) Plug all sensors into their corresponding sockets at the control box.

Note: Only use Sensor A, B, C, and D as rear sensors, and Sensor E, F, G, and H as front sensors. Don't switch the front

sensors with the rear sensors or it may cause false alert such as continuous beeping.

Installing Sensors in Metal Bumpers

If you have a continuous beeping or false alert problem after installation of the system, unplug all sensors from the control box, and then plug back in one sensor at a time and test to find out which specific sensor(s) is causing the problem.

If you find a sensor that is causing false alert, please check if the sensor hole in the bumper is too tight as instructed below: If a sensor causes false alert or gives inconsistent results, pull it out of its hole in the bumper for about 0.5 inch, tape it to the bumper so it faces upward a little bit and test to see if the false alert will stop. If the false alert stops, then the hole drilled for the sensor is a little bit tight which can apply pressure on the sensor and cause the system to give false alert. If this is the case, then carefully enlarging the hole a little bit with a small round file should solve the problem.

Testing Your New Parking Sensor System

For the rear sensors, back up your vehicle slowly (about 3 miles per hour) to approximately

2.0m (6.6 ft) from a flat vertical surface such as a wall. Continue to back up slowly and check the performance against Chart 1.

For the front sensors, do the same test while forward parking with braking. Note: have somebody watch the vehicle while you are doing the test.

Using the Beeper

The beeper beeps faster as vehicle gets closer to obstacle and sounds continuously when vehicle is within 0.4m (1.3ft) from the obstacle.

Detection Range of the System

The parking sensor system detects obstacle by emitting ultrasonic wave and receiving reflected ultrasonic wave from an obstacle. Different materials have different reflection and absorption of the ultrasonic wave, and the actual detection distance varies depending on what materials an obstacle is composed of. Human skin and clothes actually absorb the ultrasonic wave, and can only reflect very small portion of the ultrasonic wave back to the sensors, hence the system may detect human skin and clothes within a much shorter range compared to other materials. Drivers in these situations should pay more attention while parking their vehicles.
