!WARNING
Improper use of the Bendix®Wingman®ACB – Active
Cruisewith Braking systemcan resultina collisioncausing
propertydamage,seriousinjuries, or death. The ultimate
responsibility for the safe operation of the vehicle
remains with the driver. Be sure to read, understand,
and follow all these instructions carefully.

IMPORTANT SAFETY INFORMATION
Ultimate responsibility for the safe operation of the
vehicle remains with the driver at all times. Even
with the Bendix® Wingman®ACB system, the driver
must remain alert, react appropriately and in a timely
manner, and use good driving practices.
The Bendix®Wingman®ACB system must be used only
in conditions normally recommended for normal cruise
control. The Bendix®Wingman®ACB system must never
be used on roads that cannot be driven safely at a steady
speed, including city streets, winding roads and sharp
curves, steep downhill grades, poor road conditions, such
as gravel, dirt, ice or wet surfaces (wet surfaces may
increase the risk of hydroplaning), or in fog, heavy rain or
snowy conditions.
In certain situations Wingman®ACB should not be used
including: dense traffic or where smaller vehicles – such
as motorcycles are ahead in the same lane; construction
zones, off-road use, steep downhill grades; when entering
turning lanes, entering or exiting highways or similar
situations.
Vehicle manufacturers may use alerts, messages, and
dash arrangements that vary from the examples shown
here. Consultthe Vehicle Operator’sManualforapplicable
details regarding use and operation.
OVERVIEW
The Bendix®Wingman®ACB system is integrated with
the vehicle’s normal cruise control. Once the driver turns
"on" and "sets" normal cruise control, Bendix®Wingman®
ACB is engaged.
DESCRIPTION
The Wingman®ACB is an additional feature of cruise
control. Whenusing cruisecontrol, thesystem willmaintain
the“set”speed and intervene,asneeded, to help maintain
a set following distance behind a vehicle ahead in the
same lane.
Using a radar sensor (with a range of approximately
500 feet) mounted to the front of the vehicle the Bendix®
Wingman®ACB system tracks moving vehicles ahead.
Oncecruise controlis activatedand asetfollowingdistance
maintained, if the forward vehicle slows down below the
cruise control’s set speed, the system will intervene, as
necessary to perform the following tasks in this order:
(a) de-throttle the engine,
(b) apply the engine retarder, and
(c) apply the foundation brakes.
NOTE: If the foundation brakes are applied by Bendix®
Wingman®ACB or the driver, the vehicle will not resume
to the set speed automatically. The driver must "resume".
If the vehicle ahead slows below the cruise control’s
set speed, but then accelerates away, and the Bendix®
Wingman®ACB system did not need to use the foundation
brakes as it managed the intervention, the vehicle will
automatically accelerate back to the original cruise control
set speed, and again maintain the set following distance
behind the vehicle ahead.
Other system features include an audible and visual
warning system, part of which is always on, whether or not
cruise control is on and engaged. A detailed description
of warnings can be found in the "INDICATIONS AND
WARNINGS" section of this document.
Because Bendix®Wingman®ACB operates together with
normal cruise control, the typical features built into cruise
control operate as usual. For example, limits imposed by
factory-set road speed governors are fully supported by
Bendix® Wingman®ACB.
SYSTEM COMPONENTS
The radar sensor used in the Bendix®Wingman®ACB unit
is located at the front of the vehicle – either on the bumper
or just behind it on a cross-member.
The Bendix®Wingman®ACB sensor is pre-aligned at the
factoryand no adjustmentshouldbe needed. Ifthesensor
becomesmisaligned(oradiagnostic troublecode isissued)
a message, or light on the dash lets the driver know that
service is needed.
Typically the Bendix®Wingman®ACB system is fully
integrated into the vehicle dashboard so that a separate
status/display box is not required. All visual, text and
audible indications and warnings come directly from the
vehicle’sinstrumentcluster. Thevolume levelsof thealerts
are not adjustable, nor can they be switched off.

AUTOMATIC FOUNDATION BRAKE
APPLICATIONS
The Bendix®brake system automatically manages
foundation brake priorities among the various vehicle
systems that use the foundation brakes, such as Bendix®
Wingman®ACB (Active Cruise with Braking), Bendix®
ESP®ElectronicStability Program,Bendix®ATC(Automatic
Traction Control) and Bendix® ABS (Anti-lock Braking
System).
After an ACB event, in which the foundation brakes were
applied by the driver, normal cruise will automatically be
cancelled. The driver must activate “resume” or “set” for
the vehicle to throttle up.
Additional information, and complete troubleshooting
procedures for the Bendix® ESP®stability system, can be
found in Service Data Sheet SD-13-4869.
SWITCHING ON THE BENDIX®WINGMAN®
ACB SYSTEM
To operate the Bendix®Wingman®ACB system the cruise
controlmustbeswitched“on”. See Figure2 forexamplesof
switches that may be used. When the vehicle reaches the
desired cruise speed, the driver presses the cruise control
“set”switchtoactivatethesystem. Bendix®Wingman®ACB
willthen engageand helpthe drivermaintain aset following
distance behind the vehicle traveling in front.
Once the cruise control speed is “set,” a “cruise-enabled”
icon (or similar) will illuminate on the instrument panel. If
the green “cruise-enabled” or “set” (or similar) icon does
not illuminate, the Bendix®Wingman®ACB system is not
functioning normally. Refer to the Vehicle Operator’s
Manual to double-check the location of the icon and for
further troubleshooting information.
The driver can switch the Bendix®Wingman®ACB system
off manually by either stepping on the brake pedal or
switching “OFF” the cruise control.
IMPORTANT NOTE: Cruise control will automatically
cancel whenever Bendix®Wingman® ACB applies the
foundation brakes.
THE "TARGET DETECTED ICON"
When Bendix®Wingman®ACB is “on” and “set” and a
vehicleahead is detectedby theradar,theTargetDetected
Icon will illuminate on the vehicle dashboard. See Figure
3 for examples.
This is an indication to the driver that Bendix®Wingman®
ACB is enabled to assist the driver in maintaining the set
following distance.
FIGURE 2 - CRUISE CONTROL SWITCH STYLES
FIGURE 3 - TARGET VEHICLE DETECTED ICON

4
ADJUSTING THE CRUISE CONTROL SPEED
The “+/-” switch of the vehicle cruise control system is
used to increase (+) or decrease (-) the vehicle set speed.
When adjusted, the new set speed will be indicated on
the vehicle dash. The new set speed is displayed on the
message center, speedometer or other location on the
dash.
FOLLOWING DISTANCE
Following distance refers to the time gap, measured in
seconds, between the vehicle with Wingman®ACB and
the vehicle ahead. The actual physical distance between
your vehicle and the vehicle ahead will vary based on the
speeds of both vehicles; however, the set gap will remain
the same for all set cruise speeds.
FOLLOWING DISTANCE ADJUSTMENT
SWITCH
This optional ACB feature, allows the driver to adjust the
following distance or time gap. The availability of this
feature is determined by the vehicle manufacturer. The
switch has an increase or decrease function. Pressing
increase (+) will provide a larger following distance,
measured in seconds. Pressing decrease (-) will provide
a shorter following distance.
WHAT TO EXPECT WHEN USING BENDIX®
WINGMAN®ACB

Situation System Indication/Alerts Action
With cruise control "set" and a
vehicle is present (in range) ahead. Depending on the vehicle manufacturer, the cruise control "on" indicator and the "Target
Detected Icon" both will be illuminated.
ACB will help the driver to maintain the set
speed and following distance.
With cruise control "set", the vehicle
ahead slows moderately. The system may alert the driver with the Following Distance Alert (FDA). The vehicle will be slowed by (in order) (a) reducing throttle, (b) engaging the engine
retarder, or (c) applying the foundation brakes.
If the foundation brakes are applied, Bendix®
Wingman®ACB cancels after the event. The
driver needs to "resume" to reengage cruise
control.
With cruise control "set", the vehicle
ahead slows rapidly. The Following Distance Alert (fast beeping) is given, and may be followed by the Impact
Alert (continuous modulating tone), and a text
message appears on the dash screen.
The vehicle will be de-throttled, the engine
retarder engaged and the foundation brakes
applied. Bendix®Wingman®ACB cancels after
the event. The driver needs to "resume" to
reengage cruise control.
Cruise control is not "on", or not
"set", the vehicle ahead slows
rapidly.
The Following Distance Alert is given: fast
beeping sound. No action taken by the Bendix®Wingman®ACB.
The driver must take appropriate action.
With cruise control "set", but no
vehicle ahead detected (vehicles
in front of you are further than 500
feet ahead of your vehicle).
None.
Vehicle maintains "set" speed.
With the cruise control "set", a
vehicle cuts in front of the truck and
speeds away.
If the vehicle cuts in front of the truck at a
distance of 1/2 second or 15 feet or less, a
fast beeping warning is given until the vehicle
ahead is beyond the 15 feet range.
If the vehicle cuts in more than 15 feet or 1/2
second in front of your vehicle, no warning is
given.
With cruise control "set", a vehicle
cuts in front of the truck within
range of the sensor and slows
down.
The system alerts using the Following
Distance Alert (fast beeping) .
Depending on how rapidly the vehicle ahead
slows, the system may initiate an Impact Alert.
ACB reduces the throttle and retards the engine;
the foundation brakes also may be engaged.
With cruise control set, the vehicle
goes down a steep grade. If the brakes remain applied for an extended duration, the “Brake Overuse” warning will
appear on the dash display.
Reference the CDL manual instructions on
proper gear usage for down grades. The
system will begin de-throttling, followed by
engine retarder, followed by braking. If the
brakes remain on for an extended duration, the
dash display warns the driver and ACB may be
disabled. See "ACB Brake Overuse Warning"
section in this manual.
With cruise set, a faster vehicle
passes on the left or right. None. None by Bendix®Wingman®ACB. The driver
must take appropriate action.
A broken-down vehicle is stationary
in the lane in which the truck is
traveling.
No warning is given. None: Bendix®Wingman®ACB only reacts to
moving objects.
A deer runs in front of the truck. No warning is given. None: Bendix®Wingman®ACB does not
recognize non-metallic objects.
Another vehicle crosses the road
perpendicular to the truck's path of
travel – such as at an intersection.
No warning is given. No system action taken: Bendix®Wingman®
ACB does not react to objects that are moving
perpendicular to the truck's path.

HOW THE DRIVER'S ACTIONS IMPACT
BENDIX® WINGMAN®ACB
Table2 illustrates howtheBendix®Wingman®ACB system
will react to various actions initiated by the driver when
using Bendix®Wingman®ACB system on the road.
NOTE: The actions presented above reflect many, but
not all, potential driver actions that may interact with the
Bendix® Wingman®ACB system.
Ultimate responsibility for the safe operation of the
vehicle remains with the driver at all times. Even with
the Bendix® Wingman®ACB, the driver must remain
alert, react appropriately and in a timely manner, and
use good driving practices.
INDICATIONS AND WARNINGS
Bendix® Wingman®ACB functions act differently than
other cruise control/forward collision warning systems. It
is important that the driver fully understand the system’s
features, especially the driver indications and warnings.
TwoimportantwarningsprovidedbytheBendix® Wingman®
ACB system are the Following Distance Alert (FDA)
and Impact Alert (IA). The driver will be alerted by FDA
warnings,whetherornotthecruisecontrol isactivated. The
driver is only alerted to IAwarnings when in cruise control
mode with Bendix® Wingman®ACB functioning.
An additional warning of the Bendix® Wingman®ACB
system is the Close Cut-InAlert. This alert (a fast beeping
sound) activates when a vehicle cuts in front of the truck
within 1/2 second or 15 feet, or when the truck cuts in
behind a vehicle within 1/2 second or 15 feet. The alert
endswhenthedistancebetween thetwovehiclesincreases
beyond 1/2 second or 15 feet.
FOLLOWING DISTANCE ALERT (FDA)
TheFollowing DistanceAlert(FDA) isalwayson andactive
whenever the vehicle is moving 5 mph or greater (whether
or not cruise control is engaged.) This alert provides
both audible and visual warnings whenever the distance
between the truck and the vehicle ahead is less than the
set following distance and getting closer.
If the following distance continues to decrease, the driver
will hear beeping that will become faster. When the
distancereachesacritical point, the instrument clusterwill
also illuminate a red LED.
!WARNING: Any beeping tone by the Wingman®ACB
system means that the truck is too close to the vehicle
ahead.
The FDAmay be accompanied by text on the dash screen
saying“distancealert”. Once the audiblewarningis given,
the driver must increase the distance between his/her
vehicle and the vehicle ahead until the audible warning
stops.
"IMPACT ALERT" WARNING
The "Impact Alert" is the most severe warning issued by
Bendix®Wingman®ACB. The Impact Alert is only active
when your vehicle's cruise control is on, and the cruise
speed is set and Bendix® Wingman®ACB is operational.
The ImpactAlert warning indicates the driver should apply
additional braking force immediately. The warning display
varies by vehicle manufacturer. Text appears on the
dashboardscreen, redlights and/oranimpactwarningicon
may illuminate and a loud continuous modulating tone will
sound.See Figure4foranexample ofan ImpactAlertIcon.
Action Reaction of Bendix®Wingman®ACB
If the driver does this: Expect the ACB system to do this:
Steps on the brake. Both cruise control and Bendix®Wingman®ACB will be cancelled until the driver pushes “set”
or “resume”.
Steps on the accelerator. Cruise control and Bendix®Wingman®ACB will be overridden until the accelerator is released.
Then, cruise control and Bendix®ACB will resume to the original set speed automatically.
Turns the cruise control "off". Bendix®Wingman®ACB will turn off. However, the driver will hear Following Distance Alerts as
needed.
Turns the cruise control "on". Bendix®Wingman®ACB will not engage until the driver selects “set”.
"Sets" the cruise control. Bendix®Wingman®ACB is automatically activated and will help the driver maintain the set
speed and set following distance from the vehicle ahead.
Covers or blocks the sensor. Depending on the type and extent of the blockage, Bendix®Wingman®ACB will be diminished
or disabled. A blockage also will affect cruise control availability. A trouble code will be set.
Uses normal cruise "+/-" switch. Vehicle speed increased (+) or reduced (-) to achieve the new set speed while actively
maintaining the following distance with the vehicle ahead, if a forward vehicle is within 500 feet.
TABLE 2 - BENDIX®WINGMAN®ACB SYSTEM REACTIONS

7
When the Impact Alert activates, the driver must take
immediate evasive action by applying more braking
power and/or steering clear of the vehicle ahead to
avoid a potential collision.
!WARNING: Bendix®Wingman®ACB will apply up to
one-thirdof the vehicle’sbraking capacity. Thedriver must
apply additional braking, when necessary, to maintain a
safe distance from the vehicle ahead.
"ACB BRAKE OVERUSE" WARNING
Bendix®Wingman®ACBprovides awarning whenit detects
a situation that might lead to overuse of the foundation
brakes. Thisoveruse canleadto brakesoverheating anda
potentiallossofbrakingperformance causedby brakefade.
For example, this warning can arise from improper use of
ACB on long or steep downhill grades. It is recommended
that Bendix®Wingman®ACB be disengaged on long or
steep downhill grades. The driver should use appropriate
gearingandbraketechniques,not Bendix®Wingman®ACB,
on long, downhill grades.
WhentheBendix®Wingman®ACB systemissuesan "ACB
Overuse Warning" a text message will be displayed on the
dashboard and/or an audible warning sounds. Once the
driver applies the brakes or disengagesACB, the warning
is discontinued.
If the driver does not respond to the brake overuse
warning(s) after a brief delay, Bendix® Wingman®ACB will
be disabled automatically. Bendix® Wingman®ACB will be
available the next time the vehicle is started.
The driver should approach grades as he/she normally
would, with the appropriate gear selected and at a safe
speed. It is recommended that Bendix®Wingman®ACB
not be used on long or steep downhill grades!
ALERT VOLUME
The Bendix®Wingman®ACB audible alerts are pre-set at
the factory and cannot be turned off, nor can the volume
be adjusted.
POTENTIAL FALSE WARNINGS
In certain unusual traffic or roadway conditions,ACB may
issue a "false alert". While eliminating all false alerts is
not possible, if false alerts occur too frequently (more
than twice a day) this may indicate sensor misalignment.
Service the system at the earliest opportunity.
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 ACB
system.
The ultimate responsibility for the safe operation of
the vehicle remains with the driver. Even with the
Bendix® Wingman®ACB, the driver must remain alert,
react appropriately and in a timely manner, and use
good driving practices.

SensorInspection-Thedriver should regularlyinspect the
radar sensor and mounting and remove any mud, snow,
ice build-up, or other obstructions.
Sensor Damage / Misalignment / Tampering - In cases
where the bumper and/or sensor are found to have
sustained damaged, are misaligned, or if you suspect the
sensor has been tampered with, do not use the Bendix®
Wingman®ACBsystemuntil thevehiclehas been repaired
and the sensor realigned. Typically, an indicator on the
dash will illuminate if the system detects any of these
conditions. Consult the Vehicle Operator's Manual or
contact Bendix for more information.
NOTE: Any vehicle trouble code that disables vehicle
cruise control will also cause a trouble code in Bendix®

OVERVIEW OF THE BENDIX®WINGMAN®
ACB TROUBLESHOOTING PROCESS
Read through the entire list before performing any
troubleshooting. See Table 3 below.
Overview of Possible Issues
Issue Description
Normal system
operation Verify the system is functioning normally. Drivers who are unfamiliar with the system may report they don’t like the way it beeps or how it activates the brakes. Use sections STEPS TO
TROUBLESHOOTING, DIAGNOSTIC TROUBLE CODES and UNDERSTAND THE DRIVERS
COMPLAINT to verify if the system is functioning normally; then continue.
Trouble codes
caused by
temporary operating
conditions
Sometrouble codes indicatea temporary conditionand will clearwhen that conditionis no longer
present. Ifthesepersist, further investigation is warranted. Proceedtothe UNDERSTANDTHE
DRIVERS COMPLAINT section.
Sensor
misalignment If the performance of the system seems to be erratic or unpredictable, the forward radar sensor could be misaligned and may need to be aligned both vertically and laterally. If there is a trouble
code or if the system does not function, the sensor is severely misaligned and will not operate
until corrected.
Inspect the front of the vehicle. If it has been damaged or if the vehicle does not track straight,
both of these conditions must be repaired before troubleshooting Bendix®Wingman®ACB.
Sensor blocked Ifthesystem doesn’t seem towork at all, thesensoris probably blocked. Atrouble code willalso
beset. Visually inspectit,clear the blockage, turn the ignitiononand run through a power cycle.
Vehicle trouble
codes Bendix®Wingman®ACB cannot operate and will set a trouble code if any of the following vehicle systems also show a trouble code: engine, engine cruise, instrument cluster,ABS,ATC, ESP or
transmission. These components must be repaired and clear of errors before troubleshooting
Bendix®Wingman®ACB. (Note: Clearingthe vehicle troublecodes may bethe only stepneeded
to reestablish ACB function.)
Damaged sensor or
bracket Ifthevehicle hasbeenin an accident,itis likely thesensor will needtobe re-aligned. Inspect the sensorlens andhousing fordamage. Sensor discolorationor smallscratches maybe acceptable.
Significantdamagewill require sensorreplacement. Regardlessof the exterior condition,check
the trouble codes outlined in section READ BENDIX®WINGMAN®ACB TROUBLE CODES VIA
BENDIX ACom®SOFTWARE to determine if sensor replacement is necessary.

STEPS TO TROUBLESHOOTING
Follow these basic steps to quickly and accurately
troubleshoot Bendix®Wingman®ACB.
1. Verify the vehicle is equipped with Bendix®
Wingman®ACB. Look for the presence of the radar
sensor on the front of the vehicle. See Figure 1.
2. Understand the driver’s complaint. Use the
questions found in UNDERSTAND THE DRIVER’S
COMPLAINT section as a starting point to learn what
makes the driver believe it is not performing correctly.
Be sure to have a thorough understanding of the
system'sbehavior. Thiswillreducethetroubleshooting
time.
3. Read the Bendix®Wingman®ACB trouble codes
and configuration key indicators via Bendix®
ACom® Diagnostic Software (version 6.3 or later).
If the system generates a trouble code, where a lamp
or icon is illuminated on the instrument cluster, then
theBendix®ACom®DiagnosticsTool shouldbeused to
identifytheproblem. Bendix®ACom® softwareversion
6.3 or later is required for Bendix®Wingman®ACB. In
addition to reading the trouble codes, document and
review the 4 key system indicators (misalignment
value, stationary object warning indicator, mounting
offset, and configuration number) as shown in Figure
6. Verify these indicators are within the acceptable
limits according to KEY SYSTEM INDICATORS. See
Table 4.
4. Read the vehicle trouble codes on the instrument
cluster. Use the on-vehicle diagnostics menu to
identify active and inactive engine or vehicle trouble
codes.
5. Use the “Power Up Self Test” to determine if
ACB operation is normal. Determine the version of
Bendix®Wingman®ACBthat isinstalledon thevehicle.
See Figure 8 for software version identification. This
feature is available on all Bendix®Wingman®ACB
versions manufactured after 2009.
FIGURE 6 - ACOM® SOFTWARE CONFIGURATION
IMPORTANT NOTE: All vehicle trouble codes
related to the engine, transmission, instrument
cluster, engine cruise controland BendixABS,ATC
or ESP®systems first must be resolved, with no
trouble codes present during the vehicle operation
while in cruise control, to accurately diagnose the
Bendix®Wingman®ACB trouble codes.
Key System Indicators (refer to step 3 above)
Mounting Offset This value should equal 0 if the sensor is mounted on the center line of the vehicle. If the service technician
believes the sensor should be mounted offset from center, call 1-800-AIR-BRAKE.
Stationary Object
Warning Indicator This is a status indicator for the function of stationary object warning. It is available for use in Bendix®
Wingman®ACB versions after 2009.
Misalignment

Questions To Ask The
Driver Next Steps
Alignment Problems
Is the sensor mounting location
(bumper or cross member)
damaged?
Does the system seem to lose or
“notholdonto” the forward vehicle
when going around curves?
Doesthesystemseemtowarnlate
when another vehicle cuts in front
of the truck?
Doesthesystemseemtonot"see"
as far as it “used to?”
Does the system seem to be
inconsistentwhentrackingforward
vehicles?
Aretherefalsealertswhenpassing
other vehicles?
Realign the sensor vertically and laterally. Use the following procedures:
• Check the VERTICALALIGNMENTand adjust if needed.
• Check the LATERALALIGNMENT and adjust if needed.
• Check theACB MOUNTING - TheACB sensor needs a solid mounting surface in order to hold the alignment.
If the bumper or mounting cross member is damaged, replace it first, then align the sensor.
Blocked Sensor Issues
Is mud or snow covering the
sensor?
Is anything blocking the view of
the sensor?
Cleanthesensorlensimmediately. Removeanythingblockingthesensorthenpowercycleandreadanyremaining
trouble codes.
Read BENDIX®WINGMAN®ACB DIAGNOSTIC TROUBLE CODES VIABENDIX®ACOM®SOFTWARE.
Ifthe vehicle's cruise control is"set" andthe sensoris blockedby ice, snow,mud,tampering, etc. so that itcannot
"see" a forward target, Wingman®ACB will log a trouble code.
Afterthe blockageis removed,the Wingman®ACBtrouble codewill clearautomatically. Thisprocessalso willset
a vehicle cruise control trouble code which must be cleared with an ignition key cycle.
Add a visual check of the radar sensor for blockage to the driver’s pre-trip inspection checklist.
Potential False Warnings
Do false alerts seem to happen in
construction zones or going under
bridges?
Several road scenarios have a tendency to cause false warnings including construction zones and bridges (if
stationary object warning is enabled). Unless these false warnings are frequent, the system is likely reacting
normally. The driver should not set the cruise control in construction zones. If driver complaints persist, continue
askingquestions to more narrowly definethe drivingcondition presentingthe problems. Review proper operating
conditions in the Operator's Manual.
Other questions
Has the system worked properly
in the past and is not working
correctly now?
Thisisagoodindicationthatsomethinghaschangedsuchasmisalignmentofthesensor. Reviewquestionslisted
above with the driver to further diagnose the problem.
UNDERSTAND THE DRIVER’S COMPLAINT

Questions To Ask The
Driver Next Steps
Has the sensor been changed
recently? Ifso,thenewsensormaybeincompatiblewiththevehicle. FollowtheSENSORINTERCHANGEABILITYprocedure and check system trouble codes with Bendix®ACom® software.
Read BENDIX®WINGMAN®ACB DIAGNOSTIC TROUBLE CODES VIABENDIX®ACOM® SOFTWARE.
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
sensor bracket assembly. If so, realign the sensor vertically and laterally. If sensor alignment cannot be held in
place, the bracket assembly must be replaced. Verify the bumper is not damaged.
• Check the vertical alignment and adjust if needed.
• Check the lateral alignment and adjust if needed.
• Wingman®ACBMounting-TheACBWingmansensorneedsasolidmountingsurfaceinordertoholdalignment.
If the bumper or mounting cross member is damaged, replace it first, then align the sensor.
DidtheACBsensorcurrentlyonthe

and check system trouble codes with Bendix®ACom® software.
Read BENDIX®WINGMAN®ACB DIAGNOSTIC TROUBLE CODES VIABENDIX®ACOM® SOFTWARE.
With cruise control "set", does the
system consistently bring on the
foundation brakes when a forward
vehicle slows?
This is normal operation. Continue asking the driver questions to diagnose the problem. The sensor may be
blocked or misaligned. The service technician will need to check trouble codes as well.
• Check the vertical alignment and adjust if needed.
• Check the lateral alignment and adjust if needed.
CheckACBMOUNTING-Thissystemneedsasolidmountingsurfaceinordertoholdthealignment. Ifthebumper
or mounting cross member is damaged, replace it first, then align the sensor.
Read BENDIX®WINGMAN®ACB DIAGNOSTIC TROUBLE CODES VIABENDIX®ACOM® SOFTWARE.
Doesatroublecodeseemtooccur
when driving through the desert
or in barren areas (no road signs,
trees or vehicles)?
In normal operation the Wingman®ACB radar sensor may “go dormant” if it hasn’t “seen” a metallic object after a
pre-determinedperiod. This israre, butmost likelyto occurwhen driving in deserts orbarren areas. If thesensor
does “go dormant,” Wingman®ACB provides a visible warning to the driver and the vehicle also will drop out of
cruise mode, providing a sensory warning to the driver as well.
The driver must actively re-engage the vehicle’s cruise control. Once the desired cruise speed is set, Wingman®
ACB will resume operation. When metallic objects are again “seen” by the Wingman®sensor, the trouble code
previously recorded in the Wingman®system will clear automatically.
Doesthesystemseemtodisengage
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 management function provided by Bendix® Wingman®ACB.
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, Wingman®ACB 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 sensor is not plugged in properly. Clean the connectors on the wire harness as well as the sensor and reattach. If wires are chaffed, replace the wire harness. Also, check for trouble codes.

POWER-UP-SELF-TEST
The Power-Up-Self-Test is a self diagnostic check of the
Bendix®Wingman®ACB system that automatically runs
15 seconds after the engine starts, while the vehicle is
parked and when the cruise control switch is “on”. It runs
for approximately 5 seconds, checking the engine and
brake systems to make sure they are functioning properly
forACBto operate. Itwill stop ifthe vehicle ismoving or the
cruisecontrol switchis turned“off”. Whilethetestisrunning
normally, the driver should hear a short set of beeping
alerts and may get a distance alert message. During the
test, the "Target Detected" icon in the instrument cluster
may illuminate. This is normal. If Bendix®Wingman®ACB
will not function properly, a long warning beep will sound
to alert the driver and a trouble code will be logged in the
system. ThePower-Up-Self-Test isavailable onall Bendix®
Wingman®ACB versions manufactured after 2009. See
Figure 8 for software version identification.
BENDIX®WINGMAN®ACB DIAGNOSTIC
TROUBLE CODE SELF CLEARING
Many of the diagnostic trouble codes will clear when the
cause of the problem is corrected. When the technician
troubleshootsa diagnostictrouble code,itis recommended
that the Bendix®ACom®service tool be used to clear
the diagnostic trouble codes 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.
Ifthe vehicle'scruise controlcan beengaged, thatindicates
all Wingman® ACB trouble codes have been cleared.
SENSOR INTERCHANGEABILITY
Many variables must be considered when determining
whether or not a sensor can be relocated from one vehicle
to another vehicle. They include, but are not limited to,
Bendix® ESP®stability system, the instrument cluster, the
vehicle ECU, the engine and the transmission. Contact
the Bendix TechTeam at 1-800-AIR-BRAKE to determine
if this is a viable option. Warning! Do not interchange
sensors without contacting Bendix first!
FOLLOWING DISTANCE ADJUSTMENT
SWITCH (OPTIONAL)
Wingman®ACB will operate normally if not equipped with
a following distance (time gap) adjustment switch. The
vehicle will follow the forward vehicle at the distance,
depending on the configuration, chosen by the fleet owner
orcustomer. SeesectionBENDIX®ACBCONFIGURATION
AND ADJUSTMENTS.
If the vehicle is equipped with the following distance
adjustment switch and the following distance does not
change, the switch, wiring, or a controller on the vehicle
should be checked using the diagnostic procedures
described by the vehicle manufacturer. The ACB radar
sensor receives the driver's desired following distance on
theJ1939data communicationlinkfrom a controlleronthe

J1939SERIALDATACOMMUNICATIONSLINK
Checkforalossof communicationsbetween theWingman®
ACB radar sensor, the ABS controller, the engine ECU,
and other devices connected to the J1939 link. Check for
damaged or reversed J1939 wiring. Check for corroded
or damaged connectors and loose connections. Using
procedures described by the vehicle manufacturer, verify
the presence of the engine ECU and the ABS controller
on the J1939 link.
Verify the engine ECU configuration. Check for other
devices inhibiting J1939 communications.
J1939 ENGINE COMMUNICATIONS TEST
PROCEDURE
Bendix®Wingman®ACBrequires severalJ1939messages
from the engine ECU to control the engine and retarder
torque for distance control and braking. TheACB system
will set a diagnostic trouble code if one of these messages
is not present.
Use the engine manufacturer's diagnostic test procedures
to verify that there are no errors present in the engine that
may prevent the ACB system from controlling the engine
or retarder torque.
J1939 TROUBLESHOOTING PROCEDURE
1. Take all measurements at the harness connector
unless otherwise indicated.
NOTICE: DO NOT INSERT PROBES INTO THE
BACK SIDE OF THE CONNECTOR AS THIS WILL
DAMAGE THE SEALAROUND THE WIRE.
NOTICE: DO NOT INSERT ANY PROBE INTO
THE PIN ON THE MATING CONNECTOR OF THE
RADARSENSORTHATISGREATERTHAN 0.62mm
DIAMETEROR SQUARE. THIS WILLDAMAGETHE
CONNECTOR PINAND REQUIRE REPLACEMENT
OF THE HARNESS.
2. Check for damaged or reversed J1939 wiring.
If the J1939 HIGH or J1939 LOW wiring circuits
are damaged, such as shorting together, the entire
J1939 link will be lost. The failure may be intermittent
enablingtheJ1939linktooperatenormally sometimes.
In that event, multiple diagnostic trouble codes will be
logged in multiple engine and vehicle controllers.

20
If the J1939 HIGH and J1939 LOW wiring circuits are
reversed, communication over the entire J1939 link
will not be lost. Only those devices that are outside
of the failure point from other devices will not receive
or be able to transmit data messages.
3. Check for corroded or damaged wiring connector
problemssuch asopens orshorts tovoltage orground.
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
ofthe radar sensorare corroded,replacementof radar
sensor is recommended.
4. Checkforother J1939devices which maybe inhibiting
J1939communication. Theservice technician should
consult the vehicle manufacturer’s procedures for
otherJ1939 troubleshootingprocedures. Thedevice’s
powershould beremoved andmeasurements madeat
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
betweenharnesspins 2and3. The reading shouldbe
approximately 60 ohms. If it is not, the vehicle wiring
shouldbeinvestigated usingproceduresdescribed by
the manufacturer.
6. Unplug the radar sensor. With the ignition switch
off, using a multimeter, measure the resistance in
ohms, between harness pins 2 and ground. The
measurement should indicate an open circuit or very
high resistance. If this is not the case, the vehicle
wiring should be investigated using procedures
described by the manufacturer.
7. Unplug the radar sensor. With the ignition switch
off, using a multimeter, measure the resistance in
ohms, between harness pins 3 and ground. The
measurement should indicate an open circuit or very
high resistance. If this is not the case, the vehicle
wiring should be investigated using procedures
described by the manufacturer.
TROUBLESHOOTING WIRING HARNESS
All wire harness connectors must be properly seated to
maintainenvironmentalseals. Push the mating connector
until it seals with a click. When replacing an ACB radar
sensor, check that the wire harness connector is free of
corrosion before plugging into a new 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
harnessis recommended. Ifthe terminalsof thesensorare
corroded, replacement of radar sensor is recommended.
WINGMAN®ACB SENSOR MOUNTING AND
INSTALLATION
VEHICLE APPLICATIONS
The Bendix®Wingman®ACB sensor can be mounted and
installedonly onvehiclesthathaveBendix®Wingman®ACB
already installed. At this time ACB cannot be retrofit onto
vehicles, even if that vehicle is equipped with the Bendix®
ESP® stability system.
ACB SENSOR MOUNTING
WhenmountinganACBsensor,thewire harnessconnector
shouldalwayspoint down. TheACB assemblyis mounted
to the front of the vehicle using an adjustable bracket.
This adjustable bracket allows for the ACB sensor to be
properly aimed laterally and vertically to maximize ACB
system performance.
The ACB assembly should always be mounted in the
original OEM location. If this location is not in the center of
thevehicle, themounting offsetwill needto beprogrammed
throughBendix®ACom®software. (SeeCHECK LATERAL
ALIGNMENT section.)
For proper operation of your Bendix®Wingman®ACB
system, adhere to the following guidelines:
• The Bendix®Wingman®ACB sensor assembly should
be rigidly installed on the vehicle following all OEM
recommended torque specifications.
• TheBendix®Wingman®ACB sensor assemblyshould be
installed in the original OEM designated location.
• The ACB sensor cover should always be installed. This
helps protect components such as the connector and
wiring harness from road debris.
• TheACBassembly mustbe orientedsothat theelectrical
connector points down. Mounting the radar upside
down will impair performance significantly.
• 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-of-
vehiclecomponents. (NOTE: If original OEMinstallation
was behind a translucent panel, this panel must be
reinstalled. Check the panel for damage or scratches
that may impact the performance of ACB. Replace the
panel,ifnecessary, withanoriginal OEM suppliedpanel.
Do not paint over the panel.
