3.7 TROUBLESHOOTING THE DETECTION ZONE
Park the vehicle in an area with no metallic objects within 20 feet of the sensor being inspected.
• Turn the ignition ON and wait for the self-check to complete. See Table 1.
• Activate the turn signal towards the side being examined. Using a sizeable metallic object
[at least one (1) foot by one (1) foot], test the effective Detection Zone for the Bendix ™
BlindSpotter®. Note that the alert tone will sound once for each operation of the turn signal.
The technician may find it helpful to have an assistant be ready to cancel and re-apply the turn
signal as the metallic object is moved into the detection zone from the side, front, and back.
• The red LED should remain illuminated while the object is within the detection zone. The zone
should be approximately ten (10) feet from the vehicle directly in line with the sensor, and
approximately six (6.0) feet towards the front (and back) of the vehicle. See Figure 9.
If the zone is not as expected, inspect the mounting location for any obstructions, vehicle trim
damage, loose brackets, etc. and repair or relocate the sensor as needed.
See Section 1.2 in cases where the sensor needs to be relocated.
See Section 1.13 for information about the required clearance zone around the sensor.
See the Sections that follow for cases where no detection or continuous detection is experienced.

3.8 TROUBLESHOOTING WHEN NO OBJECTS ARE BEING DETECTED
Operator reports that no
objects are being detected.
Observe the power-up sequence with no metallic objects
within 20 feet of the sensor being inspected. See Table 1.
Is the
power‑up
sequence
completing?
(Do both the red and yellow
LEDs illuminate for a half-second,
followed by the red LED remaining
on for a further 5 (five) seconds,
followed by the yellow
LED illuminating and
staying ON?)
NO
Does
the yellow
LED – alone – illuminate
for 0.5 seconds, followed
by ONLY the
yellow LED?
YES
Replace
the Operator
Display Unit.
Re-run the
power-up test.
NO
YES
Place a metallic object (at least
one (1) foot by one (1) foot in size)
directly in front of the radar sensor,
three (3) to five (5) feet away.
Do both LEDs
illuminate for 0.5
seconds, followed by
continuous red and
yellow LEDs?
YES
NO
NO
Does the Operator
Display Unit change from
illuminating the yellow
LED to illuminating
the red LED?
NO
Replace the radar sensor.
Re-connect all connectors.
Re-run the power-up test.
16
YES
For any other conditions,
call 1‑800‑AIR-BRAKE
(1‑800‑247‑2725), option 2
and speak with the Bendix
Tech Team.
Since the test did not find any
evidence of a sensor malfunction,
inspect the connectors and harness
for damage and/or corrosion, etc. that
could lead to an intermittent problem.
Re-connect all connectors.
Re-run the power-up test.
Go to
Section 3.5.
3.9 TROUBLESHOOTING WHEN OBJECTS ARE CONTINUOUSLY BEING DETECTED
Operator reports that objects
are continuously being detected.
Observe the power-up sequence with no metallic objects
within 20 feet of the sensor being inspected. See Table 1.
Is the
power‑up
sequence
completing?
(Do both the red and yellow
LEDs illuminate for a half-second,
followed by the red LED remaining
on for a further 5 (five) seconds,
followed by the yellow
LED illuminating and
staying ON?)
YES
Since the test did not find any
evidence of a sensor malfunction,
inspect the connectors and harness
for damage and/or corrosion, etc. that
could lead to an intermittent problem.
Re-connect all connectors.
Re-run the power-up test.
Inspect for potential detection interference by vehicle trim, etc. If
necessary, unfasten the sensor mounting and – using the slack in
the harness – move the sensor away from the vehicle and re-run
the power-up test to verify if the system now operates correctly.
NO
See Section 1.10 for information about required radar clearance.
Do both LEDs
illuminate for 0.5
seconds, followed by
a continuous red
LED?
YES
See Section 1.2 for information about relocating the sensor as
necessary.
If relocating the sensor solves the issue, end the test.
If no interference source can be located, and moving the sensor
out from the vehicle did not change the LED behavior during the
power-up sequence, replace the sensor.
NO
Does
the red
LED – alone –
illuminate?
YES
Replace the radar sensor.
Re-connect all connectors.
Re-run the power-up test.
NO
For any other conditions, call
1‑800‑AIR-BRAKE
(1‑800‑247‑2725), option 2
and speak with the Bendix Tech Team.
