CONNECTOR PIN-OUT &
POWER REQUIREMENTS

POWER SUPPLY TESTS
1. Take all measurements at the camera’s harness
connector.
2. Place 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. Check for damaged wiring, damaged or corroded
connectors and loose connections.
4. Check the condition of the vehicle battery and associated components. Ensure the connection to ground is
secure and tight.
5. Using the procedures described by the vehicle
manufacturer, check the alternator output for excessive
noise.

The camera has two connectors. See Figure 3.

2.13 SERIAL DATA (PRIVATE
COMMUNICATIONS)
TROUBLESHOOTING PROCEDURE
1. Take all measurements at the harness connector unless
otherwise indicated.

Do not insert any probe into the pin on the mating
connector of the sensor that is greater than the width
of a terminal. Damaged connector pins will require the
replacement of the harness.
2. Check for damaged or reversed Private Communications
wiring.
If the Private Communications HIGH, or Private
Communications LOW, wiring circuits are damaged,
such as shorting together, the entire Private
Communications link will be lost. The problem may be
intermittent, enabling the Private Communications link
to operate normally sometimes. In this event, multiple
diagnostic trouble codes may be logged in the camera
and radar.
If the Private Communications HIGH, and Private
Communications LOW, wiring circuits are reversed,
communication over the entire Private Communications
link will be lost. Devices that use the affected network
will not be able to transmit or receive messages on that
network.
3. 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 the camera sensor. Replacement of the
entire harness is recommended. If the terminals of the
camera sensor are corroded, replacement of the sensor
is recommended.
4. Check for other Private Communications devices
which may be inhibiting communication. The service
technician should consult the procedures for Private
Communications troubleshooting. The device’s power
should be removed and measurements made at the
Electronic Control Unit (ECU) pins for shorts to ground
and power pins and resistance between the Private
Communications HIGH or Private Communications
LOW input circuits.
5. Unplug the camera harness. With the ignition switch
off, measure the resistance (ohms) using a multimeter
between harness pins 6 and 7. The reading should be
approximately 120 ohms. If it is not, the vehicle wiring
should be investigated.

16

2.14 POWER TROUBLESHOOTING
PROCEDURES
1. Unplug the camera. With the ignition switch ON, using
a multimeter, measure the voltage, between harness
pin 9 and ground. The measurement should indicate
10 to 16 VDC (Volts DC). If this is not the case, the
vehicle wiring should be investigated using procedures
described by the manufacturer.
2. Unplug the camera. With the ignition switch OFF, using
a multimeter, measure the voltage, between harness
pin 9 and ground. The measurement should indicate
zero VDC. If this is not the case, the vehicle wiring
should be investigated using procedures described by
the manufacturer.
3. Unplug the camera. With the ignition switch OFF, using
a multimeter, measure the voltage, between harness
pin 1 and ground. The measurement should indicate
10 to 16 VDC. If this is not the case, the vehicle wiring
should be investigated using procedures described by
the manufacturer.

2.15 COMMUNICATIONS (J1939) TEST AND
TROUBLESHOOTING PROCEDURES
The Bendix™ AutoVue® FLC-20™ camera requires several
J1939 messages from various ECUs. The camera will set
a Diagnostic Trouble Code (DTC) if one of the messages
from one of the expected ECUs is not present. Go to
the Service Data Sheet for the particular ECU for full
troubleshooting information.
Reference Documents:
• The Bendix® Wingman® Fusion™ Active Safety System
(SD‑61‑4963)
• The Bendix® ESP® EC-80™ Controller (SD‑13‑4986)
• The SafetyDirect® by Bendix CVS Web Portal
Processor (SD-65-21025)
1. Take all measurements at the harness connector unless
otherwise indicated.

Do not insert any probe into the pin on the mating
connector of the sensor that is greater than the
dimension of the mating connector. Damaged
connector pins will require the 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 problem may be intermittent,
enabling the J1939 link to operate normally sometimes.
If this occurs, multiple diagnostic trouble codes will be
logged in multiple engine and vehicle controllers.

Figure 10 – Clear Diagnostic Trouble Codes (DTC[s]) Button
If the J1939 HIGH, and J1939 LOW, wiring circuits are
reversed, communication over the entire J1939 link will
not be lost. Devices that use the affected network will
not be able to transmit or receive messages on that
network.
3. Check for poorly-crimped, corroded, contaminated, or
damaged wiring connector problems such as opens or
shorts to voltage or ground.
If the connector terminals are corroded or damaged, this
may be an indication of water intrusion into the wiring
system and possibly into the sensor. Replacement of
the entire harness is recommended. If the terminals
of the sensor are corroded, replacement of the sensor
is recommended.
4. Check for other J1939 devices which may be inhibiting
J1939 communication. The service technician should
consult the vehicle manufacturer’s procedures for
other J1939 troubleshooting procedures. The device’s
power should be removed and measurements made at
the ECU pins for shorts to ground and power pins and
resistance between the J1939 HIGH or J1939 LOW
input circuits.
5. Unplug the camera harness. With the ignition OFF,
measure the resistance (Ohms) using a multimeter
between harness pins 3 and 4. The reading should
be approximately 60 Ohms. If this is not the case, the
vehicle wiring should be investigated.

2.16 PRIVATE COMMUNICATIONS
NETWORK TEST PROCEDURE
The Bendix™ AutoVue® FLC-20™ camera requires private
network messages to and from the Bendix® Wingman®
Fusion™ system. The camera will set a Diagnostic Trouble
Code (DTC) if these messages are not present, or if there
is a problem with the private communications system. Go
to the Bendix Wingman Fusion System Service Data Sheet
(SD‑61‑4963) for full troubleshooting information.

2.17 TROUBLESHOOTING
WIRING HARNESSES
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.
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.

2.18 CLEARING DIAGNOSTIC
TROUBLE CODES (DTCs)
Cycle the ignition power, or use the Bendix ® ACom®
Diagnostic Software (version 6.8.3.2 or higher) to clear
DTCs after troubleshooting – and correcting – any problem
with the system. See Figure 10.

Whenever re-installing or replacing a camera – for example, after a windshield is replaced – the recommended
position for the vehicle must be used. Failure to install the camera in the correct position can result in
system Diagnostic Trouble Codes being set, and system performance degradation.
The ambient temperature must be in the range of 50-100º F.
Thoroughly clean the area of the windshield where the
camera will be installed with a lint-free cloth and a 50-50
water/isopropyl alcohol solution. Make certain that there is
no grease or contamination present and that the windshield
is completely dry before installing the bracket.
Use removable tape or a non-permanent marker pen to
indicate where the top of the bracket will be installed.

1. Engage the top of
the camera into the
bracket

2. Rotate the camera into
the bracket

Remove the protective film from the tape covering the
adhesive on the bracket and, using a small “torpedo” level
to be sure that it is level, install the bracket on the glass,
holding firmly [a minimum of 62 lb. (28.1 kg.) pressure] in
place for ten (10) seconds. Wait at least twenty minutes
before installing the camera, at which point a 50% bond
strength is created. The full bond between the bracket and
windshield is achieved after 72 hours.

3. Listen for the click as
the bracket engages the
camera

IMPORTANT: Double-check that
the camera is fully engaged into the
bracket.

Figure 12 – Camera Installation
To install the camera into the bracket, See Figure 12.
1. Engage the top of the camera into the bracket. There
are two channels in the camera that need to line up
with the bracket housing, so check to be sure that both
sides engage into the bracket.
2. While maintaining the engagement at the top of the
camera, rotate the rest of the camera body about that
hinge point, towards the bracket.
3. When the camera and bracket meet, there are retaining
clips built into the bracket that will snap into place,
holding the camera in position.

4. Double-check that the camera is fully engaged into
the bracket by verifying that the channel between
them has the same gap all the way around. Pull
gently on the camera to check that the tabs at the
top and bottom are engaged and that there is no
play. See Figure 12.
5. Remove any tape, or temporary marks made, during
the installation.

3.1 CAMERA REMOVAL

Do not use a twisting action when releasing the
tabs. Insert the screwdrivers and pry by moving
the handles towards each other a small amount.
Never twist the screwdrivers as the tabs may
break! Replace the bracket if the tab is broken.

(Two
Locations)

Figure 13 – Camera Release
See Figure 13. If a camera needs to be removed, locate
the two locations at the lower corners where the camera
and bracket meet.
1. Insert two medium-sized flat-blade screwdrivers into
the slots, fully seating them.
2. Then – gently prying by moving the screwdriver
handles away from the windshield a small amount –
push against the retaining clips to release the camera.

3.2 BRACKET REMOVAL
The camera must be removed prior to this procedure. The
preferred method for removing a bracket ideally requires
two technicians. Using a heat-gun, one of the technicians
gradually applies heat to the outside of the windshield at
the location of the adhesive, while the other gently applies
a prying force to the bracket while being careful not to
damage the windshield.
As soon as the ideal temperature is reached, the bracket
will release. Allow the windshield to completely cool down
before cleaning the glass and installing a replacement
bracket.
When replacing brackets, use only replacements with the
same part number or a direct superceding replacement
number supplied by Bendix or OEM. If you have questions,
contact the Bendix Tech Team at 1-800-AIR-BRAKE
(1-800-247-2725, option 2).
NOTE: Some OEMs may offer the windshield with
the bracket pre-installed. Contact the dealer for more
information.

3.3 DASH SWITCHES AND LAMPS
Each OEM has their own method for displaying the system
status to the driver, and typically there will be a switch on
the dash board to allow the driver to temporarily disable the
system. Refer to the OEM Operator’s Manual for system
indicator lamp(s) used for the Bendix™ AutoVue® FLC-20™
camera, and whether there is a bulb-check illumination at
vehicle power-up. See Figure 14 for some examples of
OEM icons used at the time this document was published.

Additionally, the system self-monitors and will set a
Diagnostic Trouble Code (DTC) that will typically alert
the driver using a similar icon on the dash display or by a
status lamp. See Section 2.0 “Troubleshooting” (page 4),
for more information.

3.4 MAINTENANCE
In normal use, the Bendix™ AutoVue® FLC-20™ camera
needs only a clean, properly maintained windshield to
ensure a clear view of the road ahead. Protect the camera
lens whenever the inside of the windshield is cleaned. You
may check that the camera’s view is clear by taking a test
image (See Appendix A).

3.5 CAMERA INTERCHANGEABILITY
When replacing cameras only use replacements with the
same part number (or a direct superceding replacement
number supplied by Bendix).

Cameras of different vehicle models and model
years must not be interchanged. The use of an
incorrect camera can lead to Diagnostic Trouble
