Refer to Section 3.1.

The Bendix™ FLC-20™ camera is a component used in
many Bendix safety systems, including:
• The Lane Departure Warning (LDW) System; and
• The Bendix® Fusion™ Active Safety System.
For more information about the Bendix Fusion System,
refer to SD-61-4963, Bendix® Fusion™ FLR-21™ Radar
Sensor, on B2Bendix.com.
This document covers installation, troubleshooting, and
replacement for this camera.

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, and/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
Read the entirety of this document before performing any
troubleshooting.
Diagnostic information is available using Bendix ACom
Diagnostic Software. ACom Diagnostic Software is a
PC-based program that is designed to meet RP1210 industry
standards developed by the Technology and Maintenance
Council (TMC). This software provides the technician with
access to all available Fusion system diagnostic information
and configuration capability, including:

•

Electronic Control Unit (ECU) information

•

Diagnostic Trouble Codes (DTCs) and repair information

•

DTC reports

To search DTCs and receive additional troubleshooting
support, refer to B2Bendix.com > Services & Support >
Diagnostic Trouble Code Search.
For additional information on ACom Diagnostic Software and
to purchase the software, refer to B2Bendix.com.
NOTE: Aftermarket-installed components may interfere
with proper system operation and/or diagnostics.
Bendix recommends the vehicle be returned to factorybuild specifications prior to performing any diagnostic
troubleshooting steps.

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 TEMPORARILY DISABLE THE LANE
DEPARTURE WARNING (LDW)
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 3.
Figure 3 – Example of an LDW
Enable/Disable Switch

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.

2.3 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.
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.

2.4 BENDIX™ DRIVER INTERFACE
UNIT (DIU™) LANE DEPARTURE
WARNING SYSTEM ICONS
See Figure 4 and Figure 5. 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

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 5 – 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.

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.

2.5 TROUBLESHOOTING DIAGNOSTIC
TROUBLE CODES: POWER SUPPLY

POWER SUPPLY AND IGNITION
VOLTAGE TESTS

All wire harness connectors must be properly seated to
maintain electrical connectivity. Push the mating connectors
until they click. When replacing a Bendix Fusion FLC-20
camera, check that the wire harness connectors are free
of damage, including corrosion, before plugging into a new
camera. Check for corroded or damaged wiring connector
problems such as opens or shorts to voltage or ground.

1. T
ake all measurements at the camera’s harness
connector.

If the connector terminals are corroded, this may be
an indication of water intrusion into the wiring system
and possibly into the camera (presumably from a
cracked windshield). Replacement of the entire harness
is recommended. If the terminals of the camera are
corroded, replacement of the camera is recommended.

4. C
heck for damaged wiring, damaged or corroded
connectors, and loose connections.

2. P
lace a load (e.g. 1157 stop lamp) across the supply
voltage and ground connection. Measure the voltage
with the load. The supply voltage on pin 1 to ground
should measure between 10 to 16 VDC (Volts DC).
3. Repeat Step 2 for ignition voltage on pin 9.

5. C
heck the condition of the vehicle battery and
associated components. Ensure the connection to
ground is secure and tight.
6. U
sing the procedures described by the vehicle
manufacturer, check the alternator output for excessive
noise.

CONNECTOR PIN-OUT AND
POWER REQUIREMENTS
The camera has two connectors. See Figure 6.
