APPENDIX A - RADAR MOUNTING AND INSTALLATION
Appendix A
Mounting the Bendix™ FLR-20™ Radar

GENERAL

Improper use of the Bendix ®
Wingman ® Advanced ™ system
can result in a collision causing
property damage, serious injuries,
or death.

Under no circumstances must the radar be removed or repositioned
from the original production line installation. The assembly should
always be mounted in the original OEM location. If this location is
not in the center of the vehicle, the mounting offset will need to be
programmed through Bendix® ACom® Diagnostic Software.

Vehicle equipment, including bumpers, deer guards, etc. must not infringe upon the zone used by the radar
sensor to emit and receive radar waves. See Appendix A3. Failure to comply with this requirement will impair
the function of the radar. Only vehicle OEM-approved covers and/or cover panels may be installed in front of
the radar.
The radar sensor assembly is mounted to the front of the vehicle using an adjustable bracket. This adjustable bracket
allows for the radar sensor to be properly aimed laterally and vertically to maximize Wingman Advanced System
performance. When mounting a radar sensor, the wire harness connector should always point towards the passenger
side of the vehicle.

A1 Vehicle Applications
The radar sensor can be mounted and installed only on vehicles that have a Bendix® Wingman® Advanced™ system
already installed. Note that some vehicles can be retrofitted with the Wingman Advanced system by certified Bendix
installers. To learn more about retrofit opportunities visit bendixcvsupgrade.com.

Sensor Mounting Clearance

•

CAUTION: Vehicle equipment, including bumpers,
deer guards, 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 and/or cover panels may be installed directly
in front of the radar.
For proper operation of your Bendix® Wingman® Advanced™
system, adhere to the following guidelines:
• The radar sensor assembly should be OEM-installed
on the vehicle following all OEM specifications.

The radar’s field of view must NOT have interference
from any other vehicle components such as bumpers,
cow-catcher bumpers, engine blankets, seasonal
decorations, or any other commonly mounted front-ofvehicle 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 bumpers or 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 the diagram
below for a general guide and an example of how to
calculate the zone required.
NOTE: Bendix does not certify nor offer warranty on
Bendix® Wingman® 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.

B1.1 General Information About Adjusting The Alignment
Accurate vertical and lateral alignment of the radar sensor is critical for proper operation of Bendix® Wingman®
Advanced™. If the alignment is outside a certain range it could cause false warnings, missed warnings, and a Diagnostic
Trouble Code (DTC) in the system.
The radar sensor is mounted to the front of the vehicle using a bracket with three stand-offs, two of which are used
when making adjustments, if necessary.
It is important to use the correct stand-off when making any alignment adjustments.
Use a Torx® T-20 screwdriver here to
adjust for the vertical alignment

IMPORTANT:
Do not adjust
this stand-off!!

B2 Lateral Alignment Using The Learned Alignment Screen
This is the preferred and recommended method for lateral alignments
This method is for vehicles with Bendix™ Driver Interface Unit (DIU™) displays that use software whose version is
12.220 and above. To verify the DIU’s software version, go to the Volume screen, where it is displayed in the top
right-hand corner.
If the radar’s lateral alignment is not correct, the system calculates over the course of many hours of driving, an alignment
adjustment value. The DIU displays the learned alignment value, and also shows the technician the direction to turn,
and number of turns to make to, the lateral alignment adjustment screw.
B2.1

Tools needed: DIU (with software version 12.220 or above), and a Torx® T-20 screwdriver.

B2.2

Enter the DIU menu item titled “Radar” and select “Alignment Check”.

B2.3

Upon selecting the “Alignment Check” menu item the following screen will be displayed:

Bendix® DIU screen showing learned alignment value

IMPORTANT:
Do not adjust
this stand-off!!

Use a Torx T-20 screwdriver here to

adjust for the lateral alignment

For example, the Figure above shows a correction value of five (5) full turns counterclockwise is needed. The
correction count and arrow direction displayed shows that in order to adjust the radar to be correctly aligned
with the travel of the vehicle, the lateral adjustment screw (lower right screw when facing the front of the vehicle)
should be turned.
B2.4

Make the adjustment shown on the Bendix DIU.

IMPORTANT: Make necessary adjustments to the alignment standoff prior to resetting the alignment value.
B2.5

Select “Reset” and then “Exit” on the Bendix DIU screen to return to the default screen.

B2.6

Cycle the ignition power.

B2.7

IMPORTANT: Before returning the vehicle to service, go to Appendix B4 and check the vertical alignment.

NOTE: The alignment process is complete after the vertical alignment has been checked (and adjusted, if
necessary.) You do not need to test-drive the vehicle.

B3 Lateral Alignment Using Bendix® ACom® Diagnostic Software
Use this method to align the Bendix FLR-20 radar laterally – when the vehicle
does not have a Bendix™ DIU™, or has a DIU (but its software version is prior to 12.220)
B3.1

Tools needed: Bendix ACom Diagnostic Software, and a Torx® T-20 screwdriver.

B3.2

Connect the vehicle to a laptop computer with the current release of the Bendix ACom Diagnostic Software.

B3.3

See the “Alignment Value” shown on the Reset Lateral Alignment Value test in available Bi-directional tests
for FLR-20.
If the alignment value shown by Bendix ACom Diagnostic Software is between -1.1° and 1.1°, this is acceptable
and the system should operate normally. A value outside that range means the radar sensor should be adjusted.

B4 Vertical Alignment Using An Inclinometer
B4.1
B4.2
B4.3

Tools Needed: A digital inclinometer, Torx® T-20 screwdriver. (If a clip from the Bendix Alignment Tool kit is
available, the clip may be placed over the front of the radar sensor during this process.)
Park the vehicle on a level floor. Air suspensions must be charged and stable.
Calibrate (or “zero”) the inclinometer on a horizontal section of the frame rail. Follow the manufacturer’s
instructions (typically digital inclinometers have a “SET” button for this purpose).
Calibrate (or “zero”)
the Digital Inclinometer
on a Cab Frame Rail
in the direction that the
vehicle travels.

B4.4

Place the calibrated digital inclinometer against the front surface of the radar, so that the tool is held in the
same direction as it was on the rail. With the digital inclinometer resting as shown, verify that the display
shows 0° (± 1.1°) from vertical, when measured by an inclinometer set to zero on the vehicle’s frame.
Use a Torx T-20 screwdriver here to
adjust for the vertical alignment

IMPORTANT:
Do not adjust
this stand-off!!
NOTE: Complete the steps below only if a vertical adjustment is necessary.
B4.5

Use the Torx T-20 screwdriver to turn by hand the top-left adjustment stand-off. During the adjustment, observe
the digital display on the inclinometer and turn the vertical alignment screw clockwise or counterclockwise
depending on the vertical direction (up or down) needed, until the reading is zero degrees.

B4.6

The radar is aligned vertically when the display is between -1.5° and 1.5°, however to achieve a more
precise alignment, adjust the vertical alignment screw until the digital alignment value is near zero (0°).
Note: The alignment process shown here is for Bendix alignment brackets. For other brackets, similar alignment
steps will be needed; consult the vehicle manual for full instructions.

B4.7

If used, be sure to remove the clip before returning the vehicle to service.
