forward collision warning system
Bendix™ VORAD® Collision Warning System
Function Test:
1.Before testing the sensor, make sure the sensor has a clear view of sight out to at least a 12 ft. diameter test area. This is most important when testing indoors because this sensor will detect stationary objects like walls, support posts, or tool chests.
2.Turn the vehicle ignition on (DO NOT START THE ENGINE) and make sure the VORAD® system powers up with no faults (clear any historic faults).
3.Verify the side sensor display inside the vehicle cab indicates NO objects are detected. If the display indicates object detection, make sure the area around the sensor is clear and the sensor mounting is appropriate. In some cases, it may be necessary to move the vehicle to a clear area.
4.Test the sensor detection by holding a metallic target (min 10" x 10") at the sensor, two meters (6 ft.) away from center. Move two meters to the left and then to the right, verifying the sensor detects the target at all three locations (see illustration below).

Note: For maximum energy reflection when testing the sensor, keep the face of the test target aimed directly at the sensor. The pattern above indicates the sensor’s maximum detection angle, and is for testing only. The sensor may not detect all objects at these angles.
The sensor’s ability to detect depends on the composition of the target and its ability to reflect pulse radar energy. The sensor may not detect humans, wood, or other
