3. Check for corroded or damaged wiring connector
problems such as opens or shorts to voltage or ground.
If the connector terminals are corroded, this may be
an indication of water intrusion into the wiring system
and possibly into the radar sensor. Replacement of
the entire harness is recommended. If the terminals
of the radar sensor are corroded, replacement of the
radar sensor is recommended.
4. Check for other J1939 devices which may be inhibiting
J1939 communication. The service technician should
consult the vehicle manufacturer’s procedures for
other J1939 troubleshooting procedures. The device’s
power should be removed and measurements made at
the ECU pins for shorts to ground and power pins and
resistance between the J1939 HIGH or J1939 LOW
input circuits.
5. Unplug the radar sensor. With the ignition switch off,
measure the resistance (ohms) using a multimeter
between harness pins 1 and 6. The reading should be
approximately 60 ohms. If it is not, the vehicle wiring
should be investigated using procedures described by
the manufacturer.

4.8 TROUBLESHOOTING
WIRING HARNESSES
All wire harness connectors must be properly seated to
maintain environmental seals. Push the mating connector
until it seals with a click. When replacing an Advanced
radar sensor, check that the wire harness connector is
free of corrosion before plugging into a new radar sensor.
Check for corroded or damaged wiring connector problems
such as opens or shorts to voltage or ground.
If the connector terminals are corroded, this may be an
indication of water intrusion into the wiring system and
possibly into the radar sensor. Replacement of the entire
harness is recommended. If the terminals of the radar
sensor are corroded, replacement of the radar sensor is
recommended.

5.1 READING BENDIX® WINGMAN®
ADVANCED™ SYSTEM KEY INDICATORS
To check the Bendix Wingman Advanced System key
indicators such as software version number, use a current
version of Bendix® ACom® Diagnostic Software. From the
main menu of ACom Diagnostic Software, the technician
highlights Advanced, then clicks “Start with ECU”. The
Advanced Status screen will appear. Clicking “Config” will
display the key system indicators. See Section 4.21 for an
example of reading the software version. See Figure 16 for
an example of ACom software configuration information.
See Appendix D.
NOTE: ACom Diagnostic Software is also used for
troubleshooting Bendix® ESP®, ATC, and ABS systems.

5.2 BENDIX WINGMAN ADVANCED
SYSTEM DIAGNOSTIC TROUBLE
CODE (DTC) SELF-CLEARING
Many of the Diagnostic Trouble Codes (DTCs) will
automatically clear when the cause of the problem is
corrected. When the technician troubleshoots a DTC, it is
recommended that a current version of the Bendix ACom
Diagnostic Software be used to clear the DTCs as directed
by the repair procedure.
Some codes will clear immediately and the functionality
will resume. Some codes will clear after powering off the
ignition for about 15 seconds and then turning it back on.
Other codes will clear after the engine runs for about 15
seconds.
If the vehicle’s cruise control can be engaged, that indicates
all Bendix Wingman Advanced System trouble codes have
been cleared.

5.3 FOLLOWING DISTANCE
ADJUSTMENT SWITCH (OPTIONAL)
If the vehicle is equipped with the following distance
adjustment switch and the following distance does not
change after an adjustment is made, the switch, wiring,
or a controller on the vehicle should be checked using
the diagnostic procedures described by the vehicle
manufacturer. The radar sensor receives the driver’s
desired following distance on the J1939 data communication
link from a controller on the vehicle. No DTC will be set
if the vehicle is not equipped with a following distance
adjustment switch.

the service technician will find a selection box called
“Configuration Number” which gives the service technician
the choices shown in Figure 18 and in Table 8.

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.

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.

ZONE THAT MUST BE
KEPT CLEAR!

Keep all deer and moose guards,
bumpers, etc. outside of the required
radar beam clearance area.
