INSPECTION AND ADJUSTMENT
Preliminary CheckINFOID:0000000003776738
DESCRIPTION
The purpose of the sonar sensor preliminary check is to confirm that there are no outside factors affecting the
sonar system.
CONDITIONS
• Ignition switch ON
• No obstructions within 3.0 m (10 ft.) of sonar sensors
SONAR SENSOR STATUS CHECK
• Check that the sonar sensors are properly aligned (no deformation in sensor mounting areas).
• Check that snow, mud or other foreign obj ects are not adhering to the sonar sensors.
• Check that there is no deformation, scratc hes or other damage to the sonar sensors.
• Check that water has not accu mulated in the sonar sensors.
CAUTION:
Use water, cotton swab, or other soft material for cleaning the sensors.
1. Check that there are no obstacles wit hin each sonar sensor's detection range.
2. Check that there are no nearby ultrasound sources such as the sounds of vehicle horns, motorcycle
engines or truck air brakes.
3. Check that the vehicle is on a level surface.
Sonar sensors Detection range
Front Approx. 1.0 m (3 ft.) maximum
Rear Approx. 1.8 m (5.9 ft.) maximum
