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, especially if you installed the sensors in a metal bumper:
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 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
Back your vehicle slowly (about 3 miles per hour) to approximately 2.5m (8.2 feet) from a flat
vertical surface such as a wall. Continue to back up slowly and check the performance against
Chart 1. Have someone watch the rear of the vehicle for you while you are doing the test.
Note:
[1] The wireless display will light up only when the control box is on (vehicle is in reverse).
[2] When you
shift into reverse gear, the system will beep once indicating it is activated.
Using the Wireless LED Display
The display has a built-in beeper (audible alert). There are seven (7) LED Lights
(Green/Yellow/Red) on each side of the two-digit distance display (Fig. 4). The color LED lights
have two functions: indicating the orientation of obstacle and showing if you are in Safe,
Warning, or Stop zone (Chart. 1).
