GENERAL SAFETY GUIDELINES
WARNING! PLEASE READ AND FOLLOW THESE INSTRUCTIONS
TO AVOID PERSONAL INJURY OR DEATH:
When working on or around a vehicle, the following guidelines should be observed AT ALL TIMES:
▲Park the vehicle on a level surface, apply the
parking brakes, and always block the wheels.
Always wear personal protection equipment.
▲Stop the engine and remove the ignition key
when working under or around the vehicle.
When working in the engine compartment,
the engine should be shut o󰀨 and the ignition
key should be removed. Where circumstances
require that the engine be in operation, EXTREME
CAUTION should be used to prevent personal
injury resulting from contact with moving,
rotating, leaking, heated, or electrically charged
components.
▲Do not attempt to install, remove, disassemble,
or assemble a component until you have read,
and thoroughly understand, the recommended
procedures. Use only the proper tools and
observe all precautions pertaining to use of those
tools.
▲If the work is being performed on the vehicle’s
air brake system, or any auxiliary pressurized air
systems, make certain to drain the air pressure
from all reservoirs before beginning ANY work
on the vehicle. If the vehicle is equipped with
a Bendix®AD-IS®air dryer system, a Bendix®
DRM™dryer reservoir module, a Bendix® AD-9si®,
AD-HF®, or AD-HFi™air dryer, be sure to drain the
purge reservoir.
▲Following the vehicle manufacturer’s
recommended procedures, deactivate the
electrical system in a manner that safely removes
all electrical power from the vehicle.
▲Never exceed manufacturer’s recommended
pressures.
▲Never connect or disconnect a hose or line
containing pressure; it may whip and/or cause
hazardous airborne dust and dirt particles. Wear
eye protection. Slowly open connections with
care, and verify that no pressure is present. Never
remove a component or plug unless you are
certain all system pressure has been depleted.
▲Use only genuine Bendix®brand replacement
parts, components, and kits. Replacement
hardware, tubing, hose, fittings, wiring, etc.
must be of equivalent size, type, and strength as
original equipment and be designed speci cally
for such applications and systems.
▲Components with stripped threads or damaged
parts should be replaced rather than repaired.
Do not attempt repairs requiring machining or
welding unless speci cally stated and approved
by the vehicle and component manufacturer.
▲Prior to returning the vehicle to service, make
certain all components and systems are restored
to their proper operating condition.
▲For vehicles with Automatic Traction Control
(ATC), the ATC function must be disabled (ATC
indicator lamp should be ON) prior to performing
any vehicle maintenance where one or more
wheels on a drive axle are lifted o󰀨 the ground
and moving.
▲The power MUST be temporarily disconnected
from the radar sensor whenever any tests USING
A DYNAMOMETER are conducted on a vehicle
equipped with a Bendix® Wingman®system.
▲You should consult the vehicle manufacturer's operating and service manuals, and any related literature,
in conjunction with the Guidelines above.
Due to the inherent limitations of image recognition
technology, camera-based safety technology — on
rare occasions — may not be able to detect or may
misinterpret lane markings. At these times, alerts
may not occur, or erroneous alerts may occur.
Bendix safety technologies complement safe driving
practices. No commercial vehicle safety technology
replaces a skilled, alert driver exercising safe driving
techniques and proactive, comprehensive driver
training. Responsibility for the safe operation of the
vehicle remains with the driver at all times.
Improper use of the Bendix®Wingman®Fusion™Driver
Assistance System can result in a collision causing
property damage, serious injuries, or death. Be sure to
read, understand, and carefully follow the instructions
in the Operator’s Manual (BW2681).
IMPORTANT
It is the responsibility of the driver to remain
vigilant and change driving practices depending
on tra󰀩c and road conditions.

NOTE: If during the intervention it is necessary to apply
the foundation brakes, or the vehicle speed falls below
the minimum cruise speed allowed, the vehicle will
not automatically resume the cruise control set speed.
EXCEPTION: It is possible that some Fusion applications
allow the cruise control to automatically resume after
the Fusion system applies the foundation brakes during
adaptive cruise. The driver is able to override the auto
resume feature by manually activating the brake pedal.
If the vehicle ahead slows below the cruise control’s set
speed, but then accelerates away – and the Fusion system
did not need to use the foundation brakes – the system will
automatically accelerate back to the original cruise control
set speed and maintain a set following distance behind any
detected forward vehicles.
Because the Bendix®Wingman®Fusion™system operates
along with normal cruise control, all the typical features
built into cruise control work as usual. For example, limits
imposed by factory-set road speed governors, etc. are fully
supported by the Fusion system.
ACTIVE CRUISE CONTROL WITH BRAKING
The active cruise control with braking feature is an
additional upgrade of ordinary cruise control. When using
cruise control, the Bendix®Wingman®Fusion™Driver
Assistance System (Fusion) will maintain the set speed,
and will also intervene – as needed – to help maintain a
set following distance behind a detected forward vehicle.
Using the Bendix®FLR-21™Radar Sensor mounted to the
front of the vehicle – with a range of approximately 500 ft
(152 m) – the Fusion system reacts to detected forward
vehicles in the same lane, traveling in the same direction.
See Figure 3.
The active cruise control with braking feature is designed to
help maintain a set following distance between the vehicle
and a detected forward vehicle when cruise control is set.
See the striped "Radar Beam" area in Figure 3.
Once cruise control is set and the system is maintaining a
set following distance between the vehicle and the forward
detected vehicle, if the forward detected vehicle slows down
below the cruise control’s set speed, the Fusion system
will intervene and, as necessary, in this order:
(a) reduce the engine throttle; then
(b) apply the engine retarder; then
(c) apply the foundation brakes
in an attempt to maintain the set following distance behind
the vehicle ahead.

ALERTS
The Bendix®Wingman®Fusion™System also assists by
giving audible and visual alerts, whether or not cruise
control is on. See Appendix E and Appendix K for more
information on the types of alerts the driver may hear and/
or see.
COLLISION MITIGATION TECHNOLOGY
See the striped area in Figure 3. The Fusion system’s
collision mitigation technology is designed to be ready to
alert the driver to detectable objects in front of the vehicle
(whether or not cruise control is set) and react to the
presence of stationary/moving vehicles in the lane ahead.
Collision mitigation interventions provide the driver with
an alert before an intervention occurs. The driver must
immediately act to potentially avoid, or lessen the severity
of, a collision.
OVERSPEED ALERT AND ACTION (OAA)
The Fusion system has the ability to assist the driver by
recognizing U.S. and Canadian speed limit signs. This
allows the system to display the current posted speed
limit and alert the driver when overspeed thresholds are
detected. When changing between regions which post
speeds in miles and those which post in kilometers, the
speed limit sign recognition feature will not function until
the correct U.S./metric selection has been made.
LANE DEPARTURE WARNING
The Fusion system will monitor the visible lane markings
on the road and when an unexpected lane change – a
lane change without an activated turn signal – takes place,
the system will alert the driver to make a correction. Tired,
distracted, or inattentive drivers are alerted and can take
remedial actions.
SAFETY DATA RECORDING AND TRANSMISSION
Many Fusion-equipped vehicles use the SafetyDirect®
by Bendix CVS processor and the vehicle’s telematics
processor to record vehicle and driver safety data after
safety system events. Data collected includes signals on
the vehicle communication network, images, video from
the Bendix™AutoVue®FLC-20™camera, and internally
generated data. Telematics devices transmit this data and
video to the SafetyDirect web portal.

1.2 NARROWING DOWN THE PROBLEM
Use the questions found in Table 2 below to help assess if the Bendix®Wingman®Fusion™system is not performing
correctly. Be sure to have a thorough understanding of the system’s normal behavior; this will reduce the troubleshooting
time. The table provides a guide to basic troubleshooting questions and possible corrective actions. Items in Italics cross-
reference to the service procedures in this manual to repair the condition described.
If Bendix Tech Team assistance is needed, prior to calling us at 1-800-AIR-BRAKE (1-800-247-2725), option 2, complete
the Troubleshooting Checklist to help reduce the time needed to troubleshoot the system.
Narrowing Down the Problem (1.2)
Questions Next Steps
Blocked Radar Sensor Issues
Is mud, ice, or snow covering the
radar sensor?
Is anything blocking the view of the
radar sensor?
Clean the radar sensor front surface immediately. Remove anything blocking the radar
sensor then power cycle and read any remaining trouble codes.
Read Section 2.5: Diagnostic Trouble Codes.
Read Appendix A3: Bendix™FLR-21™Radar Sensor Mounting Clearance.
If the radar sensor is blocked by ice, snow, mud, tampering, etc. so that it cannot "see" a
forward vehicle, the Bendix Wingman Fusion system will notify the driver by an audible
and/or visual alert. After the blockage is removed, the audible and/or visual alert will be
removed. Drivers should visually check the radar sensor for blockage during the pre-trip
inspection.
Potential False Warnings
Do false warnings seem to happen
in construction zones or going under
bridges?
Several road scenarios have a tendency to cause false warnings, including construction

Mounting Problems
Is the radar sensor mounting
location (bumper or cross-member)
damaged?
Does the system seem to not "see"
as far as it “used to”, or warn on
many more overhead bridges/signs
than previously?
Re-align the radar sensor vertically and laterally. Use the following procedures:
• Inspect the radar mounting. A solid mounting surface is necessary in order to hold the

needed. Follow the actions directed in the procedure(s) and align the radar.
• Appendix B4 - Check the vertical alignment and adjust if needed.
Does the mounting bracket look
damaged or tampered with?
Other than expected surface scratches or some discoloration over time, there should be no
visible damage to the radar sensor bracket assembly or the bumper. If no visible damage is
found, realign the radar sensor vertically and laterally.
• Check the Vertical Alignment (Appendix B4) and adjust if needed.
• Check the Lateral Alignment (Appendix B2 and B3) and adjust if needed.
The radar sensor needs a solid mounting surface in order to hold the alignment. If the
radar sensor alignment cannot be held in place, the bracket assembly must be replaced,
and/or if the bumper or mounting cross-member is damaged, replace it as needed. Where
replacing either or both of these, align the radar sensor using the procedure shown in
Appendix C.

Narrowing Down the Problem (1.2)
Questions Next Steps
Has the system worked without
problems in the past but is not
working as expected now?
This is a good indication that something has changed – such as misalignment of the radar
sensor. Review the following questions with the driver to further diagnose the problem.
Has the radar sensor been
changed recently?
If so, the new radar sensor may be incompatible with the vehicle. In addition, check any
system Diagnostic Trouble Codes (DTCs) with Bendix®ACom®PRO™Diagnostic Software.
Read Section 2.5: Diagnostic Trouble Codes.
Did the radar sensor currently on
the vehicle come from another
vehicle?
The radar sensor may be incompatible with the new vehicle. Follow Section K1.15: Radar
Sensor Interchangeability procedure and check system DTCs with Bendix ACom PRO
diagnostic software. Read Section 2.5: Diagnostic Trouble Codes.
With cruise control set, does the
system consistently apply the
foundation brakes when a forward
vehicle slows?
This is normal operation. Continue asking the driver questions to determine if the radar
system interventions are not the expected Bendix®Wingman®Fusion™system behavior. If
the radar system interventions are not typical, the radar sensor may be misaligned.
• Inspect the radar mounting. A solid mounting surface is necessary in order to hold the

needed. Follow the actions directed in the procedure and align the radar.
• Appendix B4 - Check the vertical alignment and adjust if needed.
The service technician will need to check trouble codes as well. Read Section 2.5:
Diagnostic Trouble Codes.
Does a DTC seem to occur when
driving through the desert or in
barren areas (no road signs, trees,
or vehicles)?
In normal operation, the active cruise control with braking feature of the Bendix Wingman
Fusion system may indicate a DTC if it hasn’t detected a metallic object after a pre-
determined period. This is rare, but most likely to occur when driving in deserts or barren
areas. If the system does set a DTC, the Bendix Wingman Fusion system provides a
visible warning to the driver. In addition, the vehicle will also drop out of cruise mode,

road and cycle the ignition before the vehicle’s cruise control can be used.
Does the system seem to
disengage after an automatic
braking event?
This is normal operation. The driver must set or "resume" the cruise control once again to
regain the following distance function.
Does cruise control disengage
sometimes when the brakes come
on and not at other times?
This is normal operation. When traveling with lightly loaded trailers, or “bobtail”, the active
cruise control with braking feature of the Bendix Wingman Fusion system may continue to
function even after an automatic brake application. No driver input is needed.
Does the connector or wiring
appear damaged?
Wires can become corroded if the radar sensor is not plugged in properly. Clean the
connectors on the wire harness, as well as the radar sensor, and reattach. If wires are
chafed, replace the wire harness. Also, check for trouble codes.
Read Section 2.5: Diagnostic Trouble Codes, and
Section 2.12: Troubleshooting Wiring Harnesses.
Does the system generate a DTC
going down a grade when using
ACB (Active Cruise-control with
Braking) to slow the vehicle, but the
code goes away later?
This is normal operation. The active cruise control with braking feature of the Bendix
Wingman Fusion system is not intended to be used on grades. Verify there are no DTCs.
Proper downgrade driving techniques should be used.
Read Section 2.5: Diagnostic Trouble Codes.
Does the radar sensor have
noticeable damage beyond normal
discoloration or surface scratches?
The radar sensor and bracket are very durable. However, if the radar sensor housing or
cover is cracked or broken, immediately look for trouble codes via Bendix ACom PRO
diagnostic software and replace the damaged radar sensor. Read Section 2.5: Diagnostic
Trouble Codes, and Appendix A3: Radar Sensor Mounting Clearance.

Overview of Possible Issues (1.3)
Issue Description
Vehicle Diagnostic
Trouble Codes
(DTCs)
The Bendix Wingman Fusion system will not operate and will set a DTC if any of the
following vehicle systems also show a DTC: engine, engine cruise, instrument cluster,
Bendix®ABS, Bendix®ATC, Bendix®ESP®, or transmission. These components must be
repaired and cleared of DTCs before troubleshooting the Wingman Fusion system. (NOTE:
Clearing the vehicle DTCs may be the only step needed to reestablish full Fusion system
functionality. See Section 2.6: Clearing Diagnostic Trouble Codes (DTCs).
System familiarity Verify the system functionality. Is it operating normally or not? Drivers who are unfamiliar with
the system may report dissatisfaction over the way it beeps or how it activates the brakes.
Use Section 1.0: Introduction to Troubleshooting, Section 1.1: Troubleshooting Basics, and
Section 2.5: Diagnostic Trouble Codes to verify if the system is functioning normally; then
continue.
DTCs caused by
temporary operating
conditions
Some DTCs indicate a temporary condition and will clear when that condition is no longer
present. If these persist, further investigation is warranted.
See Section 1.1: Troubleshooting Basics.
Radar sensor
blocked
If the system doesn’t seem to work at all, the radar sensor may possibly be blocked. If the
radar is blocked, an alert should be issued to the driver to indicate this condition. Visually
inspect the area around the radar, clear the blockage, turn the ignition on and run through a
power cycle. See Appendix A3 for more information about radar mounting and clearances.
Damaged radar
sensor or bracket
If the vehicle has been in an accident, it is likely the radar sensor will need to be re-aligned
or replaced. Inspect the radar sensor and housing for damage. Radar sensor discoloration

Radar sensor
misalignment
Inspect the front of the vehicle. If a) it has been damaged; or b) the vehicle does not track
straight, either of these conditions must be repaired before troubleshooting the Bendix Wingman
Fusion system.
If there is a DTC set or if the system does not function, the radar sensor may be severely
misaligned and the Wingman Fusion system will not operate until this is corrected. See
Appendix B - Radar Alignment.
J1939 network
problems
If the entire system is non-functional, it may be a J1939 network problem. Follow the
instructions in Section 2.8: Serial Data (J1939) Communications Link.
Power to radar
sensor problems
If the entire system is non-functional, another likely cause may be a lack of power to the radar sensor.

1.4 IMPORTANT NOTE ON
TELEMATICS WIRING
Where a vehicle does not have an On Board Computer/
Telematics (OBC/T) system – in order to prevent
interference to the SafetyDirect®by Bendix CVS Web
Portal Processor – disconnect the OBC/T harness (any
wiring harness provisionally installed in the vehicle for
potential use for Telematics) from the main vehicle harness.
Re-connect the harness only when an OBC/T system is
installed. (See Appendix K, Figure K6).
2.0 TROUBLESHOOTING/
DIAGNOSTICS SECTION
IMPORTANT
All vehicle Diagnostic Trouble Codes (DTCs)
related to the engine, transmission, instrument
cluster, engine cruise control, and Bendix®
ABS, ATC, or ESP®systems must first be
resolved – with no trouble codes present
during the vehicle operation while in cruise
control – before attempting to diagnose
Bendix®Wingman®Fusion™system DTCs.
Important examples are VDC2 and EBC
DTCs which are typically related to the brake
controller. The hierarchy of Electronic Control
Units (ECUs) determines that any DTCs on
the brake controller must be resolved before
attempting to troubleshoot the Wingman
Fusion system.
