Important Safety Information About The
Active Steering System by Bendix CVS
Improper use of the Active Steering System by Bendix CVS can result in a
collision resulting in property damage, serious injuries, or death. Be sure
to read, understand, and carefully follow the instructions in this document.
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.
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.
This product may expose you to chemicals including nickel, which is
known to the State of California to cause cancer and birth defects or other
reproductive harm. For more information, go to P65Warnings.ca.gov.
All vehicle Diagnostic Trouble Codes (DTCs) related to the engine,
transmission, instrument cluster, engine cruise control, and Bendix®
Antilock Braking Systems (ABS), Automatic Traction Control (ATC), or
ESP® (Electronic Stability Program) systems must rst be resolved, with
no DTCs present during the vehicle operation while in cruise control,
prior to running Bendix® ACom® PRO™ Diagnostic Software to resolve
system faults.
If a problem with the Active Steering System is detected, it should be
serviced as soon as possible to restore full functionality. The vehicle does
not need to be taken out of service. The Lane Keep Assist (LKA) feature
will be deactivated.
It is the responsibility of the driver to always keep their hands on the
steering wheel and to remain vigilant and change driving practices
depending on trac and road conditions.

Introduction
The Active Steering System by Bendix CVS helps the driver with a suite of steering-
assist features and driver-assist steering features integrated with the Bendix®
FLC-20™ camera, Bendix® Wingman® Fusion™, or a compatible third-party camera. The
active steering system combines unique active steering technology with a forward-
facing camera for active lane correction. This system helps mitigate potential side
collisions and lane-departure-related accidents, as well as increases driver comfort.
Active Steering is built on the dependable Sheppard™ HD94™ steering gear*, which
oers a quick steering ratio for less hand wheel turns, ideal for large wheel-base vehicles.
As a driver, you are always responsible for the control and safe operation of the
vehicle at all times. The Active Steering System does not replace the need for a
skilled, alert professional driver, reacting appropriately and in a timely manner,
and using safe driving practices.

System Features
Lane Keep Assist (LKA): The Active Steering System by Bendix CVS can detect
lane markings and determine the vehicle’s relative position within its lane. It also
can recognize when the vehicle begins to drift toward either the right or left lane
markings. When this occurs, LKA intervenes by adding a correction torque to the
steering wheel before the vehicle reaches the lane marking. This is intended to keep
the vehicle in its current lane of travel.The system is designed to disengage as soon as
the vehicle’s path is re-established.The driver is able to override the system and steer
the vehicle at any time.The LKA feature is available at speeds above 37 mph /60 kph.
Speed-Dependent Steering Assist: This feature provides variable steering assist
based on the vehicle speed to help the driver experience easier steering at low
speeds and a rmer steering response at higher speeds. It may also aid the driver
by helping to reduce fatigue related to steering, and can help the driver maintain
better control of the vehicle.
The driver will notice:
• The steering wheel is easier to turn at low vehicle speeds, potentially reducing
driver fatigue associated with constantly steering left or right as typically
experienced during yard maneuvering.
• The steering wheel will be rmer at higher vehicle speeds, potentially helping
the driver maintain steady lane position and steering feel.
IMPORTANT
There is no activation on/o switch for this feature. The driver should always
drive normally and safely.

5
Active Return to Center: At low vehicle speeds, this feature can help to reduce driver
fatigue through easier maneuvering by returning the steering wheel and the steer
wheels to the center position.
The driver will notice:
• The steering wheel may return to its center position after low-speed turning
events, which is especially noticeable after a backing event that requires turning
left or right.
IMPORTANT
There is no activation on/o switch for this feature.The driver can override this
feature by applying additional steering input force. The driver should always
drive normally and safely.
Road Disturbance Compensation: Road Disturbance Compensation can help
improve the driveability of the vehicle by reducing steering wheel vibration typically
caused by road disturbances like potholes, railroad tracks, road debris, or other
bumps in the road.
The driver will notice:
• When running over potholes or other bumps in the road, the driver may notice a
steadier steering wheel. Road Disturbance Compensation is designed to isolate
the bumps and not let all the vibrations be felt at the steering, which can reduce
driver fatigue. Road Disturbance Compensation may help the driver maintain
their desired direction.
• Depending on the severity of the bump, suspension of the truck and cab will
still absorb and transmit vibration. This feature only impacts vibration through
the steering wheel.
IMPORTANT
There is no activation on/o switch for this feature. The driver should always
drive normally and safely.

System Components
Bendix™ AutoVue® FLC-20™ Camera: The AutoVue FLC-20 is a forward-facing
camera that tracks the lane markers and provides the lane characteristics for the
left and right marker to the Active Steering System by Bendix CVS. The system
also provides information on when the Lane Departure Warnings (LDW) will be
suppressed, allowing the Lane Keep Assist (LKA) feature to be suppressed at the
same time. The AutoVue FLC-20 camera is compatible with later versions of Bendix®
Wingman® Fusion™ Active Safety Systems. A windshield-mounted bracket holds the
camera secure and keeps it facing in the correct direction to successfully determine
lane width and position.
• For additional information, refer to SD-64-20124, Bendix™ AutoVue® FLC-20™
Camera Service Data Sheet, on b2bendix.com.
Active Steering Electronic Control Unit (ECU): The Active Steering System ECU is
a standalone unit designed to work with J1939 Vehicle CAN and a forward-facing
lane sensing camera.
NOTE: When replacing the steering gear, the ECU must be matched to the gear
at the factory. If ordering the ECU only, please provide the gear serial number and
vehicle VIN so the ECU can be ashed at the factory to match. When purchasing a
new steering gear, you must order a new steering gear and ECU set.The existing ECU
and steering gear must be returned to Bendix to receive core charge credit.
Magnetic Torque Overlay (MTO) Power Steering Gear: The MTO power steering
gear enables hydraulic steering.
• For additional service and troubleshooting information, refer to the D-Series
Integral Power Steering Gear manual available online from the Customer Service
tab on RHSheppard.com.
IMPORTANT
Perform a visual inspection to ensure proper installation and functionality. The
power steering gear with MTO should be clean and free of uid. All connectors
around the gear should be connected and secured.
