Ultrasonic Sensor System Installation

Sensor Connection Diagram



Sensor Detection Zones

1) Safe Zone – Slow “BEEP” Sound


2) Caution Zone – Fast “BEEP” Sound


3) Danger Zone – Continuous “BEEP” Sound



4) Sensor Location

IMPORTANT! The sensor installation steps are applicable to BOTH the flush-mounted and under-mounted sensor installations. The individual sensors are labeled A, B, C, and D. The sensors should be installed in the following order:

  • Sensor A: Outer Driver Side
  • Sensor B: Inner Driver Side
  • Sensor C: Inner Passenger Side
  • Sensor D: Outer Passenger Side

It is highly recommended to install all four (4) sensors for optimal coverage and results. The system will work with less than four (4) sensors if the vehicle configuration cannot accommodate all four.

For all setups, the installer MUST make certain that sensors are centered horizontally.

  • Installation height for sensors should be between 2.5 ft. to 4 ft. above ground.
  • Sensors A and D should be located 6” to 9” from the outer edge of the vehicle.
  • When installing sensors, be certain the sensor is level, not at an angle.
  • Surface to install sensors must be vertical and flat.
  • When locating sensors, make certain that no part of vehicle (such as the hitch or other vehicle components) is within the 35° sensing range.
  • Mount sensors under the bumper with included bracket and hardware or flush into bumper in a 1-3/8” pre-drilled hole.


5) Sensor Control Box Installation

  • Mount the sensor control box in the rear of the vehicle with the included hardware. The control box itself is waterproof; it should be as sheltered from road debris and weather as possible to ensure that the connections and box can be as maintenance-free as possible.
  • The control box uses the camera interface Harness to get power from the vehicle display through the existing camera connection cable.
  • Connect the camera interface harness to the side of the sensor control box. Ensure the connection is completely tightened for a waterproof seal.
  • Connect each cable from the installed sensors to the proper sensor port on the sensor control box, Sensor A to port A, B to B, C to C, and D to D. Ensure each connection is properly tightened to obtain a waterproof seal.
  • Connect the camera Interface Harness to the camera and to the A/V cable going to the monitor display.
  • If using the external speaker, place the speaker in the vehicle cab, run the cable from the cab of the vehicle to the rear of the vehicle and connect it to the audio output on the camera interface harness.


Sensor System Operation

These 4 symbols indicate the sensors on the rear of the vehicle and the distance from the sensor to the nearest detected object. The display automatically integrates with the existing rear vision system (no special functions are required). The only user-controllable feature is the volume of the display for the audible “BEEP” tones. The following information will be displayed on the monitor when objects are detected behind the vehicle when the vehicle is in reverse.

Note: The volume of the audible “BEEP” tones on the external speaker is not adjustable.

Objects are beyond 3.5 ft. of the rear of the vehicle.
The system will display the closest object’s distance as a number in feet and inches.
There will be a slow audible “BEEP” tone.

Objects are within 3.5 ft. of the rear of the vehicle and there is danger of collision if the vehicle continues backing up.
The system will display the closest object’s distance as a number in feet and inches.
The symbol for the sensor that is detecting the closest object will flash. There will be a fast audible “BEEP” tone.

Objects are within 1 ft. of the rear of the vehicle and there is extreme danger of collision if the vehicle continues backing up.
The system will display STOP on the screen to indicate that the driver should stop immediately or proceed with extreme caution.
There will be a continuous audible “BEEP” tone.



Sensor Maintenance

Always keep sensors clear from dirt, snow, and mud. Clean sensors with a soft towel and low-pressure water. High-pressure washing can be done from a distance of at least 3 ft. away per recommendations associated with an IP67 rating.
