Introduction Tools Required

N9405T 11-05 The illustrations below show the LED display when detecting different shaped objects. The volume switch located at the top left of the display has three settings. This switch has the following options. z Beeps only, low volume zz Beeps with voice, low volume zzz Beeps with voice, high volume Digital Matrix LED Display Volume switch 1Ft, Zone 5 (Red LED) 1.0–1.9Ft, Zone 4 (Red LED) 2.0–2.8Ft, Zone 3 (Orange LED) 2.9–4.8Ft, Zone 2 (Orange LED) 4.9–8.4Ft, Zone 1 (Green LED)

N9405T 11-05 As your vehicle backs up towards an object, the beep warning will first be none when the object is beyond 8.4 feet away. Then, it will start beeping at short intervals. As you get closer to the object the beeps will lengthen until it becomes a constant tone. Stop the vehicle, you are now at less than 1 foot from the object. If the volume switch is on a voice support position, the distance and stop command will also be announced as you back up. Digital Matrix Numeric Display The digital number on display will show every 0.1M change of distance Audio warning Distance on display LED matrix display Zone 1 Zone 2 Zone 3 Zone 4 Zone 5 Zone 5 2.9~4.8 ft 4.9~8.4 ft 1.0~2.8 ft 1.0 ft 8.4ft~1.0 ft -P NOTE: Initially the system will beep when the vehicle is put into reverse.

N9405T 11-05 Detection errors may occur due to the following cases: Smooth sloping surface Smooth round object Items absorbing sound, e.g. cotton 1. Heavy rain or snow, a contaminated or damaged sensor(s) could result in detection errors. 2. Check to ensure the system is in order before use. 3. Clean sensors of any mud or debris. Immediately replace any damaged sensor when detected by the system. 4. Do not paint over the sensors as this will affect the systems performance and accuracy. 5. Heavy smoke or vapor from exhaust, due to a cold start or a poorly running engine can also result is a false reading. The back-up system only activates when the vehicle is placed in reverse gear. When placed in reverse gear the system first does a diagnostic check to ensure the system is fully functional and reports any sensor malfunctions within the back- up system. If all the sensors are normal, the system will beep once and the LED display will flash once. If there is any malfunction with the sensors, the system will beep 3-times to indicate that one or more sensors have problems. The flashing red LED(s) will indicate which sensor(s) is malfunc- tioning. The flashing LED indicates the problem sensor The total number of the problem sensors Sensor A has problem (E1: 1 problem sensor) Sensor A,D have problem (E2: 2 problem sensors) Self-Test Function False Readings

is compatible to the diameter of the sensor before drilling your bumper. Use a scrap piece of wood for this test. Note: Before drilling any holes in the vehicle ensure that the the area behind is clear of any electrical, hydraulic, or support members, etc. 2. Install the sensor vertically, the "up" arrow must be pointing up. 3. Each sensor is numbered, ensure that they are installed as shown on the illustration.0 0.3L 0.4L 0.3L 5~8 inches 5~8 inches 1 foot 8 inches~2 feet 3 inches Sensor Installation 6 © 2005 Directed Electronics, all rights reserved N9405T 11-05 Installation Note: Before installing system let the components of the exhaust system cool down. This will make the installation safer and preclude heat damage to the back up sensor wiring or components. The following illustration shows the general loca- tion of the components of the back up system. Installation Diagram Display Connect to ignition wire (+) Connect to reversing light(+) ECM Sensors

N9405T 11-05 Example Sensor Placement Calculation: 1. Measure the mounting distance between the proposed locations for sensor A and sensor D. For this example (not to be used for your vehicle) let’s say that measures 48”. 2. Then 0.3L is 0.3 X 48” = 14.4” and 0.4L is 0.4 X 48” = 19.2” 3. Hence, the distance that sensor B is from sensor A is 14.4 inches, and the distance that sendor C is from sensor D is 14.4 inches. The distance between sensor B and C will be 19.2”. NOTE: These distances are approximate as mounting locations have to be selected based on clearance behind the bumper and any obstructions or bumper curvatures on the surface of the bumper. 4. Drill the holes in the bumper as indicated in the diagrams above and install the sensors. Sensors A and D should NOT be mounted on the curve of the bumper. Note: Before drilling any holes ensure the the area behind is clear of any electrical, hydraulic, or support members, etc. Note: Wiring is shown and described is for a positive reverse indicator system. The ECU is water resistant, however, it is recom- mended that the module be mounted in the trunk compartment or for a truck in as much of a pro- tected area as possible. 1. Use the 3-sheet metal screws to mount the module. 2. Connect the white wire to reversing light(+) Mount ECU in trunk or for a truck in as much of a protected area as possible Connect the white wire to reversing light(+) sensor A sensor B sensor C sensor D reversing lingt(+) GND white black ECU ECU Installation UP UP 2. Install the sensor vertically, the "up" sign must be on upside. 1. Verify that the size of the supplied hole saw (18.5mm) is compatible to the diameter of the sensor by first drilling a test hole in a scrap piece of wood.

cables are numbered to match with the number on the sensor cable. 2. To ensure a water resistant connection at the sensors, the connectors should be seated so that the O-ring on the connector is snug against the collar of the jack before tighten- ing the connector. 3. Run the sensor interconnecting cables up into the trunk (or to the location of the ECU for a truck) and connect to the ECU module. Ensure that you connect the correct numbered sensor lead to match the connector jack on the ECU module (see illustration). 4. Connect the White wire to the reverse indica- tor wire (refer to previous illustration). 5. Connect the Black wire to the vehicle’s chassis (refer to previous illustration). Note: Discuss with the vehicle owner the placement of the display. 1. Connect the White wire to the (+) ignition wire. 2. Connect the Black wire to the vehicle’s chassis. 3. Clean the area of the dashboard where the display is going to be mounted. 4. Remove the 3M sticker off the bottom of the display. 5. Mount the display on the dashboard by firmly pressing down on the display. Use the following illustration to test and verify the operation of the backup system. Warning: Do not stand behind a moving vehicle death or injury could occur. Prior to testing, set the parking brake On, ignition key On (not start), step foot on brake and shift the vehicle into reverse.

N9405T 11-05 Ensure that the engine is not running while proceeding with the following tests. Test the system operation with a piece of wood (8 inches wide x 3 feet, 3 inches high) after the installation. Start with the wood more than 8.4 feet away from the vehicle. Then move the wood closer to the vehicle and ensure that both the audible, LED, and distance indicators display cor- rectly. No beep at power up or no LEDs flashing 1. Is power wire connected to ECU correctly? 2. Verify (+)12V at ECU when vehicle is in reverse. 3. Verify the ground connection 4. Have you connected to the correct reversing indicator wire? 5. Do you have a minimum of (+)12V and ground at the display? False warning tone or false LED flashing 1. Is the sensor mounted too low or pointing to the ground? Sensors do not detect any objects 1. Is the vehicle’s exhaust smoking? Correct or allow it to clear before proceeding with testing. 2. Are sensors properly plugged into the correct sockets? If the problem persists, please follow these steps: 1. For consumers: Contact your dealer 2. For Installer or dealer: a. Replace the ECU and re-check the system. b. Test the sensors with a known operative ECU and retest using the flat wooden board. c. Plug the known operative sensors into the ECU and re-check. d. Contact Directed tech support.
