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.
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.
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. • The audible signal has three sounds: Corner Sensors Center Sensors Sound Slow intermittent Within 2.0 feet Within 4.9 feet (60 cm) beeps...
The sensors detect the closest rear obstacle. 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. How the Backup Sensors Work When towing a trailer, the audible signal may keep sounding if the shift lever is moved to the reverse position.
Limitations The sensors may not work if the obstacle is an odd shape or made of material that does not reflect ultrasonic waves. Examples: POLE CARDBOARD CARTON SMALL TREE SOFT SNOW AND OTHER ABSORBENT OBJECTS CURBSTONE WIRE, ROPE, AND NET FENCE The sensors may not work if the ambient air temperature is below -4°F (-20°C) or above 122°F (50°C).
The audible signal may sound warning even if there is no obstacle behind the vehicle: • Sensors clogged with snow, dirt or mud 4202050Y 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 hill ©...
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.
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: For the corner sensors: From 2.0 feet (60 cm) For the center sensors: From 4.9 feet (150 cm) Confirm that the sound of the corner sensors is different from that of the center sensors.
Daily Inspection Turn the ignition switch to ON (II), and apply the parking brake. 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.
Wipe the sensors clean with a clean cloth, or flush with low-pressure water if they are clogged with mud and dirt. LOW-PRESSURE WATER 4202090Y © 2004 American Honda Motor Co., Inc. - All Rights Reserved. Caring for the Backup Sensors 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 Remedy • Clogged sensor • Wipe with a clean cloth or flush with snow or mud with low-pressure water. • Frozen sensor •...
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.
