Introduction Thank you for purchasing this Honda accessory. Please read this Owner’s Manual carefully before using the backup sensors, and keep this manual in the glove box for future reference. This product is designed to be used exclusively on a Honda Odyssey. Honda is not responsible if the unit is used for any other intended purpose. This Owner’s Manual should be considered a permanent part of the the vehicle. It should remain with the vehicle at all times and stay with the vehicle when sold.
Important Information Before using the backup sensors, make sure you read and understand the operation and limitations of the system as discussed throughout this manual. • The backup sensors are designed to provide an audible sound when they detect large stationary objects while the vehicle is moving in reverse at low speed. However, the system may not detect all objects depending on their size, shape, and location.
How the Backup Sensors Work Backup Sensors The sensors are ready for operation when the backup sensor switch is turned ON, and the shift lever is moved to the reverse position. The sensors operate by emitting ultrasonic waves. They calculate the distance between the rear bumper and an obstacle by measuring the time the ultrasonic waves take to reach the sensor after being reflected by an obstacle.

How the Backup Sensors Work The sensors are designed to give you an audible signal when the rear bumper is approaching an obstacle. • Corner Sensors: The audible signal has three sounds: Sound Slow intermittent beeps Quick intermittent beeps Continuous beep Corner Sensors Center Sensors Within 2.0 feet (60 cm) Within 1.5 feet (45 cm) Within 1.0 foot (30 cm) Within 4.9 feet (150 cm) Within 3.3 feet (100 cm) Within 1.
How the Backup Sensors Work The sensors detect the closest rear obstacle. When towing a trailer, the audible signal may keep sounding if the shift lever is moved to the reverse position. When this occurs, turn the backup sensor switch OFF. In this example, the corner sensor detects the side wall. The sensors may not detect the rear bumper of tall vehicles. © 2004 American Honda Motor Co., Inc. - All Rights Reserved.
Limitations The sensors may not work if the obstacle is an odd shape or made of material that does not reflect ultrasonic waves. The sensors may not work if the ambient air temperature is below -4°F (-20°C) or above 122°F (50°C).
Limitations The audible signal may sound warning even if there is no obstacle behind the vehicle: • • When the vehicle is equipped with a highpower radio and antenna Sensors clogged with snow, dirt or mud 4202060Y 4202050Y • When detecting loud noises such as a vehicle horn, a motorcycle’s engine, or air brakes • When driving in rain or melted snow The sensors may sound continuously under the following conditions: • When driving on rough surfaces or gravel roads or in grass, or when stopped on a h
Operation Before using the backup sensors, become familiar with the types of sounds in relation to the distances between the sensors and the obstacle by actually backing your vehicle into a garage or parking space. Also confirm the obstacle detecting range of each backup sensor. 1. Apply the parking brake. 2. Turn the ignition switch to ON (II), but do not start the engine yet. 3. Turn the backup sensor switch ON. The switch is located on the left rear pillar next to the tailgate.
Operation 5. With one of the doors open, check that the audible signal sounds by slowly bringing the palm of your hand close to each sensor as described: 6. Check that the intermittent warning beeps become quicker as you bring the palm of your hand closer to the sensor. For the corner sensors: About 1.5 feet (45 cm) For the corner sensors: From 2.0 feet (60 cm) For the center sensors: About 3.3 feet (100 cm) For the center sensors: From 4.9 feet (150 cm) 7.
Daily Inspection 1. Turn the ignition switch to ON (II), and apply the parking brake. 2. Depress the brake pedal, and move the shift lever to the reverse position. Check that the audible signal sounds for about one second. • The sensors are normal if the audible signal sounds for about one second. • If the audible signal keeps sounding, this is an indication that the sensors are frozen or clogged with mud, dirt, etc. If the sensors are clean but keep sounding, there is an abnormality in the circuit.
Caring for the Backup Sensors Wipe the sensors clean with a clean cloth, or flush with low-pressure water if they are clogged with mud and dirt. Do not spray high-pressure water against the sensors.

Troubleshooting Perform the following checks if the audible signal does not sound when the vehicle is approaching an obstacle. Symptom Take your vehicle to your Honda dealer if you encounter either of these problems: • The audible signal sounds continuously when the shift lever is in the reverse position, and the sensors are not frozen or clogged with snow or mud. • The audible signal does not sound when the shift lever is in the reverse position and the backup sensor switch is turned ON.
Troubleshooting Troubleshooting With Beeps When you turn the ignition switch to ON (II), and the backup sensor signal sounds more than once, there may be a problem with one of the sensors. Corner Sensors Two slow beeps: right sensor is faulty. Three slow beeps: left sensor is faulty. Four slow beeps: right and left sensors are faulty. Center Sensors Three fast beeps: one or both sensors are faulty. © 2004 American Honda Motor Co., Inc. - All Rights Reserved.
