The EVT-300 collision warning system provides object
detection in front of a vehicle and on the right side of a
vehicle. The forward looking radar system transmits and
receives signals for determining the distance, azimuth
and relative velocity of vehicles in front of the truck. (Azimuth is the angle, positive for right, negative for left, of
the vehicle in front. ) The EVT–300 ECU (or CPU) contains a yaw rate sensor has an internal gyro to provide
the turn rate of the vehicle which is being driven. The
yaw rate and azimuth data are combined to provide object detection when going around curves.

Electronic Control Unit (ECU)
The ECU is the brain of the EVT-300 system. The ECU
has a card slot used for programming and downloading
data. The ECU processes information from the antenna
assembly, engine ECU, Vehicle ECU, speedometer, optional side sensor, brake and turn signal circuits to
provide audible and visual warnings. It is mounted under
the center of the dash. The VORAD ECU may also be
referred to as the Central Processing Unit (CPU) in this
or other publications.
For a replacement procedure, see “Collision Warning
ECU, Replacement” page 25. For set-up information see
“Collision Warning System Set Up Using a Pro-Link”
page 31.
Accident reconstruction is an optional function which
records truck data into ECU memory. It can be used to
reconstruct the last several minutes prior to an accident.
To retrieve and analyze the data, the ECU must be
returned to Eaton VORAD. For more information on accident reconstruction, see “Accident Reconstruction” page

Antenna Assembly
The Antenna Assembly located on the front of the truck
transmits and receives low power, high frequency radar
signals. The transmitted radar signals are reflected off
objects in front of the truck and received back at the antenna assembly. The antenna assembly compares the
difference between the transmitted and received signals,
converts this information into a digital format, and transmits it to the ECU for additional processing. The antenna
assembly will simultaneously monitor up to 20 objects
within a range of 110 m (350 ft.), whether moving or stationary.
The antenna assembly is mounted in the center of the
bumper. This mounting location ensures that the radar
beam is aimed directly in front of the truck. For replacement and alignment procedures, see “Antenna
Assembly, Replacement” page 20 and “Antenna, Alignment” page 21.

Driver Display Unit (DDU)
The Driver Display Unit contains controls and indicators
related to system operation. The DDU controls system
power-up, speaker volume, range for vehicle warnings
and headway thresholds for SmartCruise®. A slot is also
provided at the front bottom edge of the DDU to insert
the optional Driver Identification Card (described later).
DDU indicator lights illuminate to indicate system power,
system failure, absence of the Driver’s Identification
Card, SmartCruise enabled, and multiple stages of
warning levels.

The side sensor is also a radar device that senses objects from 0.6–3 m (2–10 ft) from the right side of the
truck, close to the blind spot area. This information is
provided to the ECU for processing, lighting of indicator
lamps and sounding of alarms. The side sensor is
mounted on the right side of the truck, behind the cab
entry steps. For a replacement procedure, see “Side

Side Sensor Display (SSD)
The side sensor display contains red and yellow indicator lights that indicate whether or not the side sensor is
detecting an object. The yellow indicator light is on when
there is no object within the side sensor detection zone.
When the side sensor detects an object, the red indicator light illuminates and the yellow light goes off. The red
light also illuminates if the side sensor fails. When there
is heavy rain and both the red and yellow lights illuminate, the side sensor will not detect objects until the
heavy rain condition has ended. A light sensor in the
side sensor display adjusts indicator brightness with
changes in ambient light.

SmartCruise®
SmartCruise2 is an optional enhancement to the VORAD
system, and is only available factory-installed.
SmartCruise is activated whenever the vehicle’s standard cruise control system is activated. When
SmartCruise is active, the green S/C light in the upper
right corner of the Driver Display Unit will illuminate.
The “Range” control knob on the Driver Display Unit adjusts the SmartCruise “following interval”. The
SmartCruise system will either maintain the selected following interval between the truck and a vehicle ahead, or
the set cruise control speed.
lane. Again, the driver may need to apply the
service brakes to maintain a safe distance.
3
Cut In and Stay
If another vehicle in an adjacent lane cuts in
front of the truck and remains there, the system
will respond by slowing the truck to reestablish
the set following interval to the other vehicle.
The engine ECU will reduce fuel and may also
engage the engine brake (both via J1939).
Again, the driver may need to apply the service
brakes to maintain a safe distance.
4
Vehicle Ahead Changes Lane
When maintaining a following interval to a vehicle in front, and that vehicle moves into an
adjacent lane, the system will respond. If there
is no other vehicle ahead (or within range), the
truck will accelerate to the set cruise speed. If
there is another vehicle ahead, the truck will
reestablish the following interval to that vehicle.
Again, the driver may need to apply the service
brakes to maintain a safe distance.
5
SmartCruise and AutoShift Transmissions3
Under any situation that causes the system to
slow the truck, and the engine RPM reaches a
preset minimum, the AutoShift will automatically
downshift. Similarly, any situation that causes
the truck to accelerate and a preset maximum
engine RPM is reached, the AutoShift will
upshift. This is due to engine/transmisison response to the changing road speed and is not
directly controlled by the VORAD ECU program.
6
SmartCruise and Manual Transmissions
Under any situation that causes the system to
slow the truck, and the engine RPM reaches a
preset minimum, the engine ECU will disengage cruise control and the driver may need to
manually downshift the transmission. If this
happens, the truck cruise control will need to be
reengaged before SmartCruise will be operational again.
7
Road Curves and SmartCruise
SmartCruise will continue to maintain a set following interval in a gentle curve.
In a sharp curve, the system may lose track of
the vehicle in front. If this happens, the truck
will maintain its current speed. When the vehicle in front is again in view, the system will
reestablish the set following interval.
Listed below are the most common situations encountered while using SmartCruise:
•
•
Normal Cruise Control used:
If no vehicle is present in front of the truck (or if the
vehicle is out of range of the EVT-300 system).
If there is a SmartCruise failure, the vehicle will revert to normal cruise control if the cruise switch is
activated twice within 10 seconds. The red System
Failure light will remain on. The collision warning
function of the system will continue as normal.
TM
SmartCruise following interval is used:
The driver can adjust the SmartCruise following interval from 2.25 to 3.25 seconds. The following
descriptions outline SmartCruise operation.
1
2
Normal Operation
As the truck approaches a vehicle in the same
lane, the truck will slow to the speed of the
other vehicle and maintain the set following
interval. The speed reduction may be accomplished by the engine ECU or Vehicle ECU
issuing a command to reduce fuel and engaging the engine retarder (both via J1939). If the
truck speed and other vehicle speed are very
different, the driver may need to apply the service brakes to maintain a safe distance.
Cut In and Out
If another vehicle in an adjacent lane cuts in
front and continues to the opposite adjacent
lane, SmartCruise may respond. If the speed of
the other vehicle is faster than that of the truck,
the truck will maintain its speed. But if the
speed of the vehicle is less than the truck’s
speed, the engine ECU will issue a command
to reduce fuel and may also engage the engine
brake (both via J1939). Once the other vehicle
moves out of the truck’s lane, the truck will
reestablish the cruise control speed or resume
the following interval if another vehicle is in the

Vehicle Information Management System
(VIMS)
The VIMS (Vehicle Information Management System)
Office Information Kit is a comprehensive PC data base
program which supplements the Collision Warning System.
VIMS software can be used by fleet maintenance and
safety departments to manage driver operations in a variety of ways. Safety Departments use the software
program to follow driver habits and can take corrective
action when their fleet benchmarks are being exceeded.
Maintenance Departments use VIMS to verify that operational parameters are being met: for instance, idle time
within fleet acceptable limits, engine not driven to governed limits, or cool down times are being followed.
Data is downloaded from the VORAD ECU onto a cybercard so that the information can be loaded onto a PC.
Design and Function
Accident Reconstruction
Accident reconstruction is an optional function which
records truck data into ECU memory. It works like an airplane’s "black box" by recording vital information for
reconstructing events leading up to an accident.
Such information includes a second-by-second (up to 10
minutes) recounting of the trucks’s proximity to other vehicles, speeds of the vehicles involved in the accident,
brake actuation, steering wheel position, alerts the driver
received, and much more.
Accident reconstruction is used as follows: in the event
of an accident, there are two possible segments of ECU
memory that can store data. By pressing and holding the
“Range” knob for 5 seconds, the last 10 minutes of data
stored in memory are frozen and two segments are created. The first segment remains frozen while the second
segment cannot be frozen and will continue to record
data.
To retrieve and analyze the data, the ECU must be returned to Eaton VORAD.

Service Procedures
General Work Practices
Repairs should only be attempted by qualified and trained technicians. Do not attempt
repairs without the use of a Pro-Link 9000® diagnostic tool equipped with an Eaton
VORAD cartridge or Eaton applications PCMCIA card.
The Prolink 9000 diagnostic tool is used for establishing a variety of system options,
confirming operation, and for clearing the fault codes. It is important to note that some
repairs will require a test drive using the Prolink to verify correct system operation. Refer to the Prolink section in this guide ( “Collision Warning System Set Up Using a
Pro-Link” page 31) for specific operation.
Alternatively, the Driver Display Unit (DDU) is capable of providing flash codes when
placed in Failure Display Mode. To initialize and use the Failure Display Mode of the
DDU, do one of the following:
•
With the ignition off, press and hold the DDU’s Volume Control/Power On/Off knob.
Turn the ignition key on, while continuing to hold the knob for five seconds, then
release. Fault codes will blink on the display.
•
Or, if the unit has On/Off capability (most do not), press and hold the Volume Control/Power On/Off knob for five seconds, then release. Fault codes will blink on the
display.
The section, "System Check", describes the system set up using the Prolink diagnostic
tool. The Prolink is currently the only tool which allows technicians access to the EVT300 operational parameters. These parameters should be checked prior to repair to
ensure specific customer options remain unchanged if repaired and/or replaced. In
some instances, it may be necessary to add or remove options to the EVT-300, which
will require the Prolink (see “Collision Warning System Set Up Using a Pro-Link” page
31).
Eaton’s Service Ranger (version 1.25 or higher) can be used to read fault codes in addition to the Pro-Link tool.

Note: Alignment of the antenna assembly is a repetitive
process of adjusting the vertical and horizontal axes.
Slots in the antenna assembly “L” brackets allow for adjustment to take place.
Note: This procedure assumes that the tow eye mounting holes are identical, symmetrical and undamaged. If
the tow eye mounting holes have been damaged or distorted, the alignment may be incorrect.
Note: The antenna must be aligned with the vehicle
level. Be sure air suspension system is fully inflated and
that the vehicle is parked on a level surface. Use the digital protactor J-38460A on the vehicle frame rail to check
that the vehicle is within 0.5 of level before beginning
antenna alignment procedure.

CHECK OUT. From the CHECK OUT
menu, select the following tests:
1
Gyro Test
When operating the vehicle on streets and highways
during data collecting procedures, it is mandatory to
have a second person drive while a technician collects the data. Failure to do so may cause a collision,
which can result in serious injury or death.
To perform the test drive, select a
straight, flat road with light traffic that
will allow the test vehicle to be driven
straight ahead while following another
vehicle centered in your lane. A highway with multiple lanes, such as an
interstate highway, is ideal for test
drives.
6
During the test drive select CHECKOUT MENU, then GYRO TEST. The
following will display on the Pro-Link
screen. BIAS V is a voltage (read in
hexadecimal numbers) which represents the centerpoint of the gyro at
rest. If the preset limits are exceeded,
a failure will be issued. TURN RATE is
a reading of degrees per second that
changes from 0.0 when going straight
ahead, to a plus or minus value when
turning right or left, respectively.

radar speed will be a negative value
and conversely will be positive when
closing on the vehicle.
The RANGE indication is the distance
to the target vehicle sensed in front of
the antenna assembly, and is displayed
in feet. Rate is the relative speed difference (in MPH), between the host
vehicle and the target vehicle. Azimuth
is the angle, positive for right, negative
for left, of the movement of the target
vehicle compared to the host vehicle.

PPM is used to calculate vehicle speed
when the discrete speed input is used.
Since all VN series vehicles use J1939
for the speed source, the PPM does
not need to be checked or changed.
19
Perform the ANT TEST on a straight
road with light traffic that will allow the
test vehicle to be driven straight ahead
while following another vehicle centered in your lane.
15
SPEED MODE is where the ECU is
informed of the speed source information. See previous steps.

When properly aligned, the Pro-Link
display should report AZIMUTH as 0.0
when tracking the vehicle directly
ahead. The AZIMUTH reading will
probably “bounce” ±0.4 due to normal
side-to-side movement of the vehicle
ahead. Note: If the AZIMUTH reading
is consistently positive, the antenna
assembly should be aligned more to
the right. If it is consistently negative,
align it more to the left.

ERROR LOG MENU
ERROR LOG
There are two menus where logged faults can be viewed. The first is the ERROR LOG.
The Error Log menu can be accessed from the EVT-300 MENU by scrolling either up
or down in the menu. The second area where fault codes can be viewed is in the MPSI
Pro-Link Selection Menu. See “Active and Inactive Fault Log” page 40 for more information.
The ERROR LOG is selected from the EVT-300 MENU. The ERROR LOG display provides a listing of all fault codes that the system has detected. Every 15 seconds the
system ECU performs a self diagnostic test of its internal processes and of the other
system components. Faults that occur are logged into the system memory as a fault
code. A complete listing of these fault codes along with their associated SID and FMI
numbers are provided in table page 40. The SUB number shown is for Eaton’s internal
use, and will be used if calling for technical support.
For each fault code selected, the ERROR LOG displays the count /duration of each
fault, the date and time of the first and last occurrence of each fault. The ERROR LOG
display appears as follows:
CODE 34
CLR CT/MIN

Viewing the ERROR LOG
The CODE line of the ERROR LOG displays the current fault code number and indicates whether it is an active or inactive fault. The next line lists the fault name for the
current fault code and sub-code selected. The CLR CT/MIN line of the display shows
the number of occurrences of the current fault code and the number of minutes it has
been continuous.
Note: Each time a fault reoccurs, the count window increments whether active or inactive, and time continues to lapse.
Note: The system stores information for up to 255 counts for each fault and 999 minutes per count.
The fourth line of the display provides the time and date of the first occurrence of the
current displayed fault code while the LAST line of the display provides the time and
date of the last occurrence of the current displayed fault code. To view ERROR LOG information for the different fault codes stored in the system memory, proceed as follows:
1
Position display selection arrow next to CODE (first line of display). The first fault
code in the error log is listed.
Note: All information in the ERROR LOG display pertains to the current fault code
listed.
