▲ Never exceed manufacturer’s recommended
pressures.
▲ You should consult the vehicle manufacturer's operating and service manuals, and any related literature,
in conjunction with the Guidelines above.

Improper use and/or maintenance of the Bendix® Wingman® Fusion™ Active Safety 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.

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.

IMPORTANT
It is the responsibility of the driver to remain vigilant and change driving practices depending on traffic and
road conditions.

How to identify if the vehicle has the
Bendix® Wingman® Fusion™ Active Safety System:
Look for the Bendix®
brand logo on the camera
label. (Refer to Section
3.1 for how to remove
the camera from
the bracket to view
the label.)

2.0 TROUBLESHOOTING
2.1 SAFETY GUIDELINES
Read and follow the General Safety Guidelines shown in
this document.

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 DTCs present during
the vehicle operation while in cruise control, before
trying to resolve camera DTCs.

IMPORTANT
If a problem with the Bendix™ AutoVue® FLC-20™ camera
is detected, it should be serviced as soon as possible
to restore full functionality.

2.2 BENDIX™ DRIVER INTERFACE
UNIT (DIU™) LANE DEPARTURE
WARNING SYSTEM ICONS
See Figure 3 and Figure 4. In the case of vehicles that
use a Bendix™ Driver Interface Unit (DIU™), the top right
corner of the display is used to show an icon. For other
OEM displays, see the vehicle manual to find the method
used to show the system status.

During Start-Up – System Busy
The first symbol shows when the Lane
Departure Warning (LDW) system is
initializing.
Camera Impaired
If the system experiences
problems detecting objects (for
example, due to sun-glare, a
dirty windshield, obstructions,
etc.), a full DIU screen message
will briefly be displayed.
The screen will revert to displaying
the icon shown, until the problem is
resolved.
Normal Operation
The LDW system is actively seeking
lane-markings.

The LDW system is actively tracking
lane-markings on both sides of the
current lane.

The system is actively tracking only
lane-markings on the left.

The system is actively tracking only
lane-markings on the right.
Figure 3 – Normal Bendix DIU Screens Showing
Lane Departure Warning (LDW) System Status
Diagnostic Trouble Code (DTC) Set
If no LDW status is shown – and the
driver has not applied the LDW disable
switch – this indicates that the system
has detected a DTC.
Figure 4 – Bendix DIU Screen Showing
LDW System Status
In these cases, the OE vehicle dash display will also alert
the operator that there is a DTC present.

2.3 CAMERA TEST IMAGE

Take a Test Image Using the Latest Version of Bendix
ACom® PRO™ Diagnostic Software

®

2. Inspect the image. You may use the pan/zoom controls
to examine the details of the image.

Troubleshooting a camera may be assisted by
viewing a test image from the camera to ensure
it is not blocked, or has another problem.
•

•

Connect a current version of Bendix® ACom® PRO™
Diagnostic Software, select ‘Bi-Directional’ from the
main menu, then select the FLC-20 controller from
the list.
Select the ‘Camera Snapshot Test’ from the list of
available FLC-20 tests and click ‘Start’.

3. Save if needed by clicking on ‘Save Image’.

1. Click ‘Get Image’ to initiate camera snapshot.

2.4 TEMPORARILY DISABLE THE
LANE DEPARTURE WARNING (LDW)

2.6 BENDIX® ACOM® PRO™
DIAGNOSTIC SOFTWARE

To avoid erroneous LDW warnings in areas such as
construction zones – where the non-standard or overlapping
road markings present might cause false alerts – the
Bendix® Wingman® Fusion™ Active Safety System (Fusion)
has an enable/disable switch. The Bendix switch design or
a similar OEM switch may be used. See Figure 5.

Bendix® ACom® PRO™ Diagnostic Software is a PC-based
software program available to purchase from bendix.com.
This software provides the technician with access to all
the available Electronic Control Unit (ECU) diagnostic
information and configuration capability. For Fusion system
diagnostics, use the current version of Bendix ACom PRO
Diagnostic Software. See Figure 6.

Figure 5 – Example of an LDW
Enable/Disable Switch

For vehicles that have the LDW switch hard-wired to the
SafetyDirect® by Bendix CVS Web Portal Processor, and a
functioning On Board Computer (OBC)/Telematics system:
The enable/disable switch used by the Lane Departure
Warning (LDW) system also functions – when depressed
for six (6) seconds – to activate a manual request to
transmit the last five seconds and next five seconds of
buffered video data.

2.5 SETTING DIAGNOSTIC
TROUBLE CODES (DTCs)
If, during operation, the Bendix Wingman Fusion system
detects a problem with the Bendix™ AutoVue® FLC-20™
camera, a Diagnostic Trouble Code (DTC) will be set and
– depending on the OEM – the driver will be alerted on the
dash display with an icon or similar method. In these cases,
some features of the Fusion system will not be available.
If, for an extended period of time, the system detects that
the camera is blocked by dirt, snow, ice, etc., a Diagnostic
Trouble Code (DTC) will typically be set.

IMPORTANT
Bendix®-brand Electronic Control Units (ECUs) are
not designed to store data for purposes of accident
reconstruction and Bendix® ACom® PRO™ Diagnostic
Software is not intended to retrieve data for purposes
of accident reconstruction. Bendix makes no
representations as to the accuracy of data or video
retrieved and interpreted from ECUs for purposes
of accident reconstruction. Bendix does not offer
accident reconstruction services or interpretation of
stored data. Bendix ECUs are not protected from fire,
loss of power, impact damage, or other conditions that
may be sustained in a crash situation and may cause
data to be unavailable or irretrievable.

2.7 STARTING BENDIX® ACOM®
PRO™ DIAGNOSTIC SOFTWARE

2.8 READING DIAGNOSTIC
TROUBLE CODES (DTCs)

The Bendix® ACom® PRO™ Diagnostic Software can be
started from the desktop shortcut. See Figure 7.

1. Connect a current version of the Bendix ACom PRO
Diagnostic Software to the vehicle.
2. Once the roll call is complete, you can view active
and inactive DTCs and clear DTCs from all vehicle
components or the FLC-20 controller.
3. To read and clear DTCs from all vehicle components at
the same time, select vehicle on the roll call and clear
faults by clicking on ‘clear faults’.

Figure 7 – Starting Bendix® ACom® PRO™ Diagnostic
Software
To begin, the technician should select ‘Connect’ from the
main toolbar, then ‘Heavy Duty’ connection type. See
Figure 8.

Figure 8 – Bendix ACom PRO Diagnostic Software –
Hardware Interface Screen

4. To read and clear DTCs from a specific Bendix ECU,
select the FLC-20 on the roll call and clear faults by
clicking on ‘clear faults’.
For assistance with Bendix ACom PRO Diagnostic
Software, call 1-800-AIR-BRAKE (1-800-247-2725, option
2, option 2).

.

The Heavy Duty button connects to the vehicle BUS using
all vehicle protocols. This process could take approximately
two minutes. After the connection is complete, the roll call
will show the ECU, and its active and inactive Diagnostic
Trouble Codes (DTCs). Connection depends on a
compatible RP1210C adapter. For assistance with Bendix
ACom PRO Diagnostic Software, call 1-800-AIR-BRAKE
(1-800-247-2725, option 2, option 2).

2.9 DIAGNOSTIC TROUBLE CODES
Use a J1939 detection software to find the DTC(s) and use
the Table in Section 2.10 to find the service action code to
use. The service actions to take may then be found in the
Table shown in Section 2.11.
If the troubleshooting devices available to the technician
provide Suspect Parameter Number (SPN) and
Failure Mode Identifier (FMI) code combinations, refer to
Appendix A.
