Troubleshooting
One or more warning LEDs remain on and a tone is heard, but
there are not objects behind the vehicle.
•
Inspect the radar sensor for proper mounting, debris buildup, or
damage.
• Check for suspended objects or overhead clearances within a
15 feet radius of the radar sensor.
• Inspect the radar sensor for proper mounting. Verify the sensor
is pointing outward from the vehicle in an open area with no
obstructions in its view.
• If the sensor is detecting the ground, reposition the sensor
higher on the vehicle, or at a slight upward angle (2 to 5
degrees). The minimum recommended height from the ground
is 30 inches (75 mm).
The detection zone seems wider when detecting large objects
like other vehicles, than when detecting smaller objects or
people.
•
This is normal since vehicles have a greater radar cross
section than smaller objects, non-metallic objects, and people.
The interconnect harness to the rear sensor display is too
short.
•
Harness extensions can be purchased in 20-foot (7 meter)
increments (P/N 41365-100).
The backup alarm does not sound when used with the
(optional) relay out harness (P/N 41371-100).
•
Verify the positive lead on the backup alarm is hooked to the 1
amp fused relay out harness lead and the negative lead is tied
to the chassis ground.
• Check the 1 amp fuse in the relay out harness. DO NOT use a
fuse larger than 1 amp.
