
A sensor blockage indication - verify that the sensor face is clean.
All the display LEDs are illuminated when sensor is mounted.

Verify the sensor is pointing outward from the vehicle in an open area
with no obstructions. This may require removing the mounting screws
and lifting the sensor out and away from the rear of the vehicle. If the
display LEDs are not active when moved away from the vehicle, but
are active when mounted, then the sensor’s mounting position will
have to be moved.
Sensor is detecting the ground, indicated by a few of the display LED’s
being lit.

In an open field, either move the sensor up higher or slightly angle the
sensor upward 2 to 5 degrees. The minimum recommended mounting
height is 24 inches.
