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.

▲ 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® 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.

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® Antilock Braking
System (ABS), Automatic Traction Control (ATC), or
Electronic Stability Program (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 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 Original
Equipment Manufacturer (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 LDW
system is initializing.
Camera Impaired
If the system experiences
problems detecting objects
(for example, due to severe
weather conditions, 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
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 TEMPORARILY DISABLE THE LANE
DEPARTURE WARNING (LDW)

2.5 BENDIX® ACOM® 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® Fusion™ Active Safety System has an enable/
disable switch. The Bendix switch design or a similar OEM
switch may be used. See Figure 5.

Bendix ® ACom ® 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
Diagnostic Software.

Figure 5 – Example of an LDW
Enable/Disable Switch

IMPORTANT

For vehicles that have the LDW switch hard-wired to the
SafetyDirect® by Rand McNally® Web Portal Processor,
and a functioning On Board Computer (OBC)/Telematics
system: The enable/disable switch used by the 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.

2.4 SETTING DIAGNOSTIC
TROUBLE CODES (DTCs)
If, during operation, the Bendix Fusion system detects a
problem with the FLC-20 camera, a 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 or all features of the Fusion system or LDW
system will not be available.

Bendix®-brand Electronic Control Units (ECUs) are
not designed to store data for purposes of accident
reconstruction and Bendix® ACom® 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.

2.6 DIAGNOSTIC TROUBLE CODES
Use a J1939 detection software to find the DTC(s) and
refer to Table 1 to find the service action code to use. The
service actions to take may then be found in Table 2.

If the system experiences problems detecting objects
(for example, due to severe weather conditions, a dirty
windshield, obstructions, etc.), a DTC will typically be set.
