AutoVue® Lane Departure Warning (LDW) System by Bendix CVS
1.0 DESCRIPTION
1.1 SYSTEM COMPONENTS
The AutoVue Lane Departure Warning (LDW) System by
Bendix CVS gives drivers the ability to combat lane drift
related to: drowsiness/fatigue, distractions, and adverse/
unfavorable weather conditions.
The system components include a digital camera mounted
near the middle of the windshield inside the cab, an enable/
disable switch (typically with status lamps), a driver alert
system (speakers and/or a vibrating seat), and a central
processing unit in the overhead console.
®
At speeds above 37 mph (60 kmph), the AutoVue system
tracks visible lane markings including both solid and dashed
shoulder lines, center lines, and lines between lanes.
When an unexpected lane change takes place – a lane
change without an activated turn signal – the system alerts
the driver to make a correction.
Some vehicles connect the AutoVue system to the vehicle’s
telematics communication system (See Appendix A:
Bendix™ SafetyDirect® system).
The camera is
mounted to the
windshield
The AutoVue LDW system is intended only as an
aid for a conscientious and alert driver. It may not
provide any warning of unintended lane departures
under certain conditions. Do not rely solely on
the system to safely operate the vehicle. It does
not warn of all possible hazards. For example, the
system cannot help prevent an accident if the driver
is impaired or not driving safely.
Ultimate responsibility for the safe operation of the
vehicle remains with the driver at all times.

GENERAL SAFETY GUIDELINES
WARNING! PLEASE READ AND FOLLOW THESE INSTRUCTIONS
TO AVOID PERSONAL INJURY OR DEATH:
When working on or around a vehicle, the following guidelines should be observed AT ALL TIMES:
▲ Park the vehicle on a level surface, apply the
parking brakes and always block the wheels.
Always wear personal protection equipment.
▲ Stop the engine and remove the ignition key
when working under or around the vehicle.
When working in the engine compartment,
the engine should be shut off and the ignition
key should be removed. Where circumstances
require that the engine be in operation, EXTREME
CAUTION should be used to prevent personal
injury resulting from contact with moving,
rotating, leaking, heated or electrically-charged
components.
▲ Do not attempt to install, remove, disassemble
or assemble a component until you have read,
and thoroughly understand, the recommended
procedures. Use only the proper tools and
observe all precautions pertaining to use of those
tools.
▲ If the work is being performed on the vehicle’s
air brake system, or any auxiliary pressurized air
systems, make certain to drain the air pressure
from all reservoirs before beginning ANY work
on the vehicle. If the vehicle is equipped with a
Bendix® AD-IS® air dryer system, a Bendix® DRM™
dryer reservoir module, or a Bendix® AD-9si™ air
dryer, be sure to drain the purge reservoir.
▲ F o l l o w i n g t h e v e h i c l e m a n u f a c t u r e r ’s
recommended procedures, deactivate the
electrical system in a manner that safely removes
all electrical power from the vehicle.
▲ Never exceed manufacturer’s recommended
pressures.
▲ Never connect or disconnect a hose or line
containing pressure; it may whip. Never remove
a component or plug unless you are certain all
system pressure has been depleted.
▲ Use only genuine Bendix ® brand replacement
parts, components and kits. Replacement
hardware, tubing, hose, fittings, etc. must be of
equivalent size, type and strength as original
equipment and be designed specifically for such
applications and systems.
▲ Components with stripped threads or damaged
parts should be replaced rather than repaired.
Do not attempt repairs requiring machining or
welding unless specifically stated and approved
by the vehicle and component manufacturer.
▲ Prior to returning the vehicle to service, make
certain all components and systems are restored
to their proper operating condition.
▲ For vehicles with Automatic Traction Control
(ATC), the ATC function must be disabled (ATC
indicator lamp should be ON) prior to performing
any vehicle maintenance where one or more
wheels on a drive axle are lifted off the ground
and moving.
▲ The power MUST be temporarily disconnected
from the radar sensor whenever any tests USING
A DYNAMOMETER are conducted on a Bendix®
Wingman® Advanced™-equipped vehicle.
▲ You should consult the vehicle manufacturer's operating and service manuals, and any related literature,
in conjunction with the Guidelines above.
Due to the inherent limitations of image recognition
technology, the lane departure warning (LDW)
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.
Bendix active and supportive safety technologies,
including AutoVue® LDW, do not replace the need
for safe drivers. No commercial vehicle safety
technology replaces the most important safety
component of all – a skilled, alert professional
driver exercising safe driving habits, as well as
continuous, comprehensive driver training.
IMPORTANT: It is the responsibility of the driver to remain
vigilant and change driving practices depending on traffic
and road conditions.
Ultimate responsibility for the safe operation of the
vehicle remains with the driver at all times.

The system uses speakers to emit a distinctive “rumble
strip” sound on the appropriate side, (or optional vibration
from the left or right portions of the driver’s seat alert if a
non-audible warning is preferred).
The AutoVue LDW system is optimized to reduce false
alarms, however the driver may temporarily use the enable/
disable switch to silence multiple occurrences.

2.1 POTENTIAL FALSE AND MISSED ALERTS
In certain unusual traffic or roadway conditions, the AutoVue® LDW system by Bendix CVS may issue a false alert.
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 AutoVue LDW system.
Overview of Potential Issues
Issue
Description
A system Diagnostic
Trouble Code (DTC)
is present.
If the AutoVue LDW system finds a problem at power-up or during operation, it will set a
DTC and will disable the system. The amber lamp will be ON, and the green lamp OFF.
System cannot

•
Mis-installed camera (incorrect placement, not level, loose, etc. See page 6 for full
details of camera installation specifications.) Note: When re-mounting a camera bracket,
use Bendix windshield adhesive ‑ p/n 493088201 ‑ do not use substitutes.
•
Road markings are hard to see (faded/missing lane markings, standing water, snow, or
mud/sand/dirt/debris on the road).
•
Inclement weather (heavy rain, fog, snow, smoke, ice or sleet, etc. is blocking the lane
markings).
•
Camera’s view is not clear (glass not clean, chipped or cracked, not installed where the
windshield wiper cleans the glass, other distortion).
Headlight(s) are not operating or are mis-aimed.
Sun glare or other light source blinds the camera, obscures the lane markings, or makes
other road markings (e.g. tar strips) look like lane markings.
®
Use J1939 detection software to find the DTC code. Go to the Troubleshooting Section
(page 7) to find the recommended repair.

FIGURE 7 - EXAMPLES OF POTENTIAL ISSUES
NOTE: These are potential situations and responses that might occur when using the AutoVue LDW system. All possible
situations and responses are not covered here.
2.2 SETTING DIAGNOSTIC TROUBLE CODES
The AutoVue LDW system is self-monitored and if any
malfunction is detected, a Diagnostic Trouble Code (DTC)
will be set and the driver will be alerted by the amber status
lamp being illuminated, and the green enabled lamp will
be OFF. See the Troubleshooting Section (page 7), for
more information.
2.3 MAINTENANCE
In normal use, the AutoVue LDW system needs only a
clean, properly maintained windshield to ensure a clear
view of the road ahead.
2.4 CAMERA AND ECU
INTERCHANGEABILITY
AutoVue LDW systems are vehicle make and model
specific. Each part number is customized to a windshield
configuration and offset. When troubleshooting, or when
replacing cameras or Electronic Control Units (ECUs), only
use replacements with the same part number (or a direct
superceding replacement number supplied by Bendix).
2.5 ALERT VOLUME
Audible alert levels are pre-set at the factory and can not
be turned off, nor can the volume be adjusted.

3.4 ADVANCED TROUBLESHOOTING
Refer to the AutoVue® LDW system by Bendix CVS wiring
diagram on page 12, during these procedures.
General. Inspect the camera and its lens, for any damage
and the wiring for any pinching or cuts. If a camera bracket
appears to have been reinstalled, check if the bracket is
level by removing the camera (slide upwards), and use
a torpedo level on the bracket tabs (See Figure 8, on
page 6). Note that the other vehicle cab accessories
must be carefully installed since mounting screws, etc.
that penetrate locations where the AutoVue components
or wiring are routed can cause shorts or wiring breaks.
If you do not have the capability to read the J1939 error
codes it is recommended to, in turn swap out components
with known good system components in the following order:
switch; processor; camera.
In practice this would result in:
•
•
•
Temporarily replace the switch with a known good
switch, retest. If this does not correct the problem put
the original switch back in.
Temporarily replace the processor box with a known
working unit. If this does not correct the problem put
the original box back in.
Temporarily replace the camera with a known working
unit. If this does not correct the problem put the original
camera back in.
If after temporarily replacing all the major components the
green lamp still fails to illuminate, hardware issues have
been eliminated and the technician can focus elsewhere
(wiring, mis-installation, etc.) for the source of the problem.
Confirm the processor part number:
Potentially a processor may have been programmed for
one vehicle model but was mis-installed or moved to a
different vehicle model. Call Bendix to verify that you
have the correct processor part number on the vehicle.
In cases where — after start-up — an Enable/Disable
switch is pressed but the “enable” (green) and “status”
(amber) lamps remain on:
1. Conditions: Vehicle parked, with the ignition on. Using
a voltmeter connect the positive (+) lead to gray wire
and the negative lead (-) to a good chassis ground, do
not use the black wire on switch for ground.
2. The voltage reading should be between 3.2 V to 3.6 V.
3. Using a voltmeter connect the positive (+) lead to the
switch pin black wire and the negative lead (-) to a
good chassis ground.
4. The voltage reading should be between -0.10 V to
0.1 V.
5. If the above voltages are not correct, turn off the ignition
and remove the switch from the switch socket.
6. Using an Ohmmeter, connect the positive (+) lead
to the gray wire, and the negative lead (-) to a good
chassis ground, do not use the black wire.
7. The resistance reading should be between 30k Ohms
and 70k Ohms.
8. If the resistance reading is less than 30k Ohms,
disconnect the main connector from the processor
and recheck the resistance of the gray wire. If the
resistance is still less than 30k Ohms, then a short
may exist in the wiring harness (for example, a screw
may have been driven in to the wire).
9. If the resistance reading is greater than 70k Ohms, an
open circuit may exist in the wiring harness.
10. Using an Ohmmeter, connect the positive (+) lead
to the black wire and the negative lead (-) to a good
chassis ground.
11. The resistance reading should be less than one (1) Ohm.
12. If the resistance reading is greater than one (1) Ohm,
an open circuit may exist in the wiring harness.
13. If the above voltages are correct, turn off the ignition
and remove the switch from the switch socket.
14. Using an Ohmmeter, connect the positive (+) lead to
blue wire and the negative lead (-) to a good chassis
ground, do not use the black wire.
15. The resistance reading should be greater than
10k Ohms.
16. Using an Ohmmeter, connect the positive (+) lead to
violet wire and the negative lead (-) to a good chassis
ground, do not use the black wire.
17. The resistance reading should be greater than
10k Ohms.
In cases where — after start-up — an Enable/Disable
switch is pressed but the “enable” (green) lamp remains
on and the “status” (amber) lamp does not remain on:
1. Conditions: Vehicle parked, with the ignition on, and
all LDW components (camera, processor, & switch)
are connected.
2. Turn off the ignition and remove the switch from the
switch socket.
3. Using an Ohmmeter, connect the positive (+) lead to
blue wire and the negative lead (-) to a good chassis
ground, do not use the black wire.
4. The resistance reading should be greater than 10k
Ohms.
13
5. If the resistance is less than 10k Ohms, then disconnect
the main connector from the processor and recheck
the resistance on the blue wire. If the resistance is
still less than 10k Ohms then a short may exist in the
wiring harness (a screw may have been driven in to
the wire). If the resistance is greater than 10k Ohms
then temporarily replace the processor with a known
good unit and re-test.
3.5 CLEARING DIAGNOSTIC
TROUBLE CODES (DTCS)
Once the problem has been found and resolved, clear the
AutoVue® LDW system Diagnostic Trouble Codes (DTCs)
by cycling the ignition power.
6. Reconnect the main connector to the processor
and recheck the resistance on the blue wire. If the
resistance is greater than 10k Ohms then temporarily
replace the processor with a known good unit and
re-test
