WARNING
The driver is always responsible for the control and
safe operation of the vehicle at all times. The Bendix™
BlindSpotter® Radar system does not replace the
need for a skilled, alert professional driver, reacting
appropriately and in a timely manner, and using safe
driving practices.
WARNING
Any audible and/or visual alert by the system means
that a vehicle has been detected by the Bendix
BlindSpotter system and the driver must immediately
act to potentially avoid, or lessen the severity of, a
collision.
Improper use of the Bendix BlindSpotter system
could lead to a serious accident. Read this entire
Service Data Sheet before operating the Bendix
BlindSpotter system. Pay particular attention to the

in conjunction with proper training.
Limitations of Collision Warning Systems
The Bendix BlindSpotter side collision warning
system is intended solely as an aid for an alert and
conscientious professional driver. It is not to be used
or relied upon to operate a vehicle. The system should
be used in conjunction with rear view mirrors and other
instrumentation to maintain safe operation of the vehicle,
ground personnel, and adjacent property. A vehicle
equipped with the Bendix BlindSpotter system should
be operated in the same safe manner as if the system
were not installed. The system is not a substitute for
normal safe driving procedures. It will not compensate
for any driver impairment, such as drugs, alcohol, or
fatigue. Should the system become inoperative, it could
jeopardize the safety or lives of those who depend on
the system for safety.
WARNING
The system will not sense objects if the sensor view is
obstructed. Therefore, do not place objects in front of
the system sensor. Remove heavy buildups of mud, dirt,
ice, and other materials.
Proper installation and placement is critical to correct
operation of the system.
Testing and inspection of the system in accordance with
these instructions and record of the results should be
listed on the daily maintenance report. The units on
operating vehicles must be tested each day (see the
“Testing System Operation” section) prior to the vehicle’s
operation. Results of this test must be recorded in the
maintenance log. People operating this equipment MUST
check for proper operation at the beginning of every shift
or safety inspection period.
People’s lives depend on the proper installation of this
product in conformance with these instructions. It is
necessary to read, understand, and follow all instructions
shipped with the product.
Failure to follow all safety precautions and instructions
may result in property damage, serious injury, or death.
The Bendix BlindSpotter system is intended for commercial
use. Proper installation of this system requires a good
understanding of truck electrical systems and procedures,
along with prociency in the installation.
Store these instructions in a safe place and refer to them
when maintaining and/or reinstalling the product.
Some of the tests in this manual require the technician to

1.2 SENSOR LOCATION
The Bendix™ BlindSpotter® Side Object Detection Sensor
must be mounted on the side of the vehicle, between 22
and 36 inches from the ground and at least 18 inches rear
of the side view mirror (See Figure 4).
Note: To reduce the possibility of the sensor detecting
objects mounted to the vehicle — like the steps or fuel
tanks — make sure the face of the sensor extends out a
minimum of 5/16 of an inch further than any other object
within six (6) inches of the sensor’s body.
1.3 SENSOR ORIENTATION
The Bendix BlindSpotter Sensor should be mounted on a
vertical surface and oriented so that the embossed logo
is parallel to the ground — you may use the lower two

1.5 WHAT TO EXPECT WHEN USING THE BENDIX™ BLINDSPOTTER® SYSTEM
Tables 1 and 2 illustrate what to expect from the Bendix™ BlindSpotter® system in various driving situations.
POWER-UP TEST
What to Expect at Vehicle Power-Up
Situation Typical System Indication/Alerts
At vehicle power-up (with no metal object within
the sensor’s detection zone).
TABLE 1 - POWER-UP TEST SEQUENCE
• Both the red and yellow LEDs illuminate for a half-second as
a system self-test, followed by;
• The red LED remains on for a further 5 (ve) seconds as a
sensor self-test, followed by;
• The yellow LED illuminates and stays ON.
(Note: if, instead, a metal object is within the sensor’s detection
zone, the yellow LED will extinguish, and the red LED will
illuminate.)
What to Expect During Vehicle Use
Typical System Indication/Alerts
Situation
Normal driving (no other vehicle present
alongside).
The driver passes a vehicle, or a vehicle enters
the sensor detection zone alongside the vehicle.
A guard-rail, or similar large metallic object, is
detected by the sensor.
The driver passes by any non-metallic object or
person (e.g. pedestrian, wooden structure, etc).
The driver activates the left turn signal, and the
sensor on the left side of the vehicle detects a
large metallic object.
Note: The sensor is wired to the turn signal on
the same side of the vehicle as the sensor is
mounted (e.g. A right-hand turn signal causes a
right-hand mounted display to illuminate the red
LED and sound a tone if a vehicle is detected).
The driver activates the turn signal (towards a
side of the vehicle with the Bendix BlindSpotter
system installed) with no vehicle in the detection
zone on that side.
Both red and yellow LEDs remain illuminated. ON
Power supply disconnected from Bendix

Other Indicators
WARNING
Due to inherent limitations of radar technology, the
Bendix™ BlindSpotter® technology — on rare occasions
— may not detect sizable, metallic (radar-reective)
objects in the detection zone. Alerts, or warnings may
not occur.
1.6 ALERTS AND WARNINGS
The Bendix BlindSpotter system operates differently
compared to other collision warning systems. It is
important for YOU to fully understand the system’s
features, especially the driver alerts and warnings.
WARNING
Any audible and/or visual alert by the system means
that a sizable, metallic (radar-reective) object has
been detected by the Bendix BlindSpotter system and
the driver must immediately act to potentially avoid,
or lessen the severity of, a collision.
1.7 BENDIX BLINDSPOTTER SYSTEM
DIAGNOSTIC TROUBLE CODES
The Bendix BlindSpotter system monitors itself and if any
malfunction is detected, a Diagnostic Trouble Code (DTC)
will be set and the driver will be alerted by the illumination
of both the red and yellow LEDs.
1.8 RADAR SENSOR REPLACEMENT
Sensors should only be replaced using like-for-like part
numbers, or their direct replacements, as provided by
the OEM or Bendix. Contact the Bendix Tech Team at
1-800-AIR-BRAKE (1-800-247-2725), option 2, to request
part number assistance.
WARNING
Do not interchange radar sensors without contacting
Bendix rst!
1.9 ALERT VOLUME
Bendix BlindSpotter systems permit the audible alert level
to be adjusted by pressing the top button on the Operator
Display Unit. To adjust the volume, press the button and
the unit will cycle between low, medium and high, and back
through the sequence.
1.10 POTENTIAL FALSE ALERTS
In certain unusual trafc or roadway conditions, the Bendix
BlindSpotter systems may issue a false alert.
Drivers should take into account the road conditions, and
any other factors they are encountering, as they choose
how to react to any alerts they receive from the Bendix
BlindSpotter system.
1.11 RADAR CLEARANCE
CAUTION
Vehicle equipment, including trim, etc. must not
infringe upon the zone used by the radar sensor to
emit and receive radar waves. Failure to comply with
this requirement will impair the function of the radar.
Only vehicle OEM-approved covers, trim and/or cover
panels may be installed around, or directly in front of,
the radar.

The only
exceptions
are vehicle
OEM-approved
covers or trim
FIGURE 7 - CLEARANCE ZONE AROUND THE SENSOR
For proper operation of your Bendix BlindSpotter system,
adhere to the following guidelines:
• The radar sensor assembly should be OEM-installed
on the vehicle following all OEM specications.
• The radar’s eld of view must NOT have interference
from any other vehicle components such as hand rails,
aftermarket lights, seasonal decorations, or any other
commonly mounted vehicle components. The radar
signal is emitted from the front of the sensor with a
spreading beam. In order to ensure that no adverse
interference is experienced from other nearby vehicle
equipment, a suitable clearance must be maintained
around the radar. This clearance must be maintained
regardless if the vehicle is stationary or in motion. See
Figure 7 for a general guide to the zone required.
• To reduce the possibility of the sensor detecting
objects mounted to the vehicle — like the steps or fuel
tanks — make sure the face of the sensor extends out
a minimum of 5/16 of an inch further than any other
object within six (6) inches of the sensor’s body. See
Figure 7.
NOTE: Bendix does not certify, nor offer warranty on,
Bendix BlindSpotter systems where system performance
is affected by beam obstructions of any kind or unapproved
post-production covers. This document gives general
guidelines that will work for most vehicles; exceptions
may exist.

2.1 EQUIPMENT MAINTENANCE
WARNING
The driver is always responsible for the control
and safe operation of the vehicle at all times. The
Bendix™ BlindSpotter® system does not replace the
need for a skilled, alert professional driver, reacting
appropriately and in a timely manner, and using safe
driving practices.
Importance of Maintenance – Optimal Bendix™
BlindSpotter® system performance requires a properly
maintained system, without any active Diagnostic Trouble
Codes (DTCs). Have problems indicated by active DTCs
repaired by a qualied technician.
System Problems – If a problem with the Bendix
BlindSpotter system is detected, either both the red and
yellow LEDs will be illuminated, or — in the case of power
supply problems — there will be no LEDs illuminated. The
system should be serviced as soon as possible to restore
full functionality.
2.2 PREVENTIVE MAINTENANCE
The Bendix BlindSpotter system is relatively maintenance
free. The key items to keep the system functioning properly
include:
1. Keep the radar sensor clean and free of obstructions,
mud, snow, bugs, etc... using OEM-approved cleaning
products.
2. Inspect for any damage to the unit or the Bendix
BlindSpotter mounting surface or bracket. Never use
the radar unit as a step.
NOTE: If the radar sensor was originally installed on a
vehicle panel, check the panel for damage, etc... that
may affect the radar’s performance before reinstalling.
Replace the panel, if necessary, with an original
OEM-supplied panel. Do not paint over the radar.
Radar Inspection – The driver should inspect the
radar and mounting bracket regularly and remove any
mud, snow, ice build-up, or other obstructions. The
installation of aftermarket vehicle guards — or similar
potential obstructions — is not recommended, and could
impair the operation of the radar.
Radar Damage/Tampering – In cases where the
vehicle body and/or radar have sustained any damage,
or if you suspect that the radar has been tampered with,
consider disabling the Bendix BlindSpotter until repairs can
be made. In addition, an indicator on the dash typically
will illuminate if the system detects any of these conditions.
Consult your vehicle’s operator’s manual or contact Bendix
for more information.

Repeat this test to double-check
the results of the test. If a second
test does not nd any abnormalities,
replace the Operator Display Unit.
3.7 TROUBLESHOOTING THE DETECTION ZONE
Park the vehicle in an area with no metallic objects within 15 feet of the sensor being inspected.
Turn the ignition ON and wait for the self-check (See Table 1) to complete.
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 nd 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, the 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 ve-and-a-half
(5.5) 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 (See Table 1) with no
metallic objects within 15 feet of the sensor being inspected.
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 (ve) seconds,
followed by the yellow
LED illuminating and
staying ON?)
NO YES
Does
the
yellow LED —
alone — illuminate
for 0.5 seconds,
followed by ONLY
the yellow
LED?
Replace
the Operator
Display Unit.
Re-run the
power-up test.
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 ve (5) feet away.
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.
YES
NO
Do
both
LEDs
illuminate for 0.5
seconds, followed by
continuous red and
yellow LEDs?
NO
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 nd 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.
YES
Go to
Section 3.5.

3.9 TROUBLESHOOTING WHEN OBJECTS ARE CONTINUOUSLY BEING DETECTED
Operator reports that objects
are being continuously reported.
Observe the power-up sequence (See Table 1) with no
metallic objects within 15 feet of the sensor being inspected.
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 (ve) seconds,
followed by the yellow
LED illuminating and
staying ON?)
YES
Since the test did not nd 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.
NO
Do
both
LEDs
illuminate for 0.5
seconds, followed by
a continuous red
LED?
NO
Does
the red
LED — alone —
illuminate?
NO
YES
YES
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.
See Section 1.10 for information about required radar clearance.
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.
Replace the radar sensor.
Re-connect all connectors.
Re-run the power-up test.
For any other conditions,
call 1-800-AIR-BRAKE
(1-800-247-2725), option 2
and speak with the Bendix
Tech Team.
