Before You Begin
The VORAD® VS-400 system is comprised of a Forward Looking Radar (FLR) unit and Driver Interface Unit (DIU) that utilizes the vehicle’s
J1939 data link to communicate with each other, as well as the vehicle’s engine and/or chassis (cab) controller. It is recommended that the
servicing technician be properly trained and familiar with the vehicle’s electrical system, J1939 data link, and electronic components before
attempting any of the troubleshooting procedures in this manual.
For information on training opportunities, along with up to date service bulletins and product literature, contact your local Bendix account
manager or visit the Bendix website at www.bendix.com.
Additional Warnings
Some of the tests in this manual require the technician to use a test meter to measure the voltage and resistance of the vehicle’s electrical
circuits. If it becomes necessary to temporarily connect the test meter leads to wire harness terminals, it is recommended to use a test lead
adapter kit (see recommended tools for P/N J-43318) or equivalent.
•
ever insert test lead probes, nails, or paper clips into the vehicle harness connector terminals, as this can distort or damage the
N
wire terminals.
•
Never pierce wire insulation to test circuits, as this can result in damaged wires and wire corrosion.
•
hen making resistance checks on circuits, make sure the vehicle ignition is off to prevent damage to test equipment and vehicle
W
components.

Product Definitions
Safety Information
Definitions
Forward Looking Radar (FLR)
The VORAD® VS-400 Forward Looking Radar is a high frequency Doppler radar unit located on the front of the vehicle that transmits a
focused beam of radio frequency (RF) energy ahead of the vehicle. Energy reflected off objects is reflected back to the FLR and processed
by the unit’s internal headway controller to determine the speed, distance, direction, and lane position of all detected objects.
Collision Warning System (CWS)
The headway controller within the FLR processes information about all objects detected by the radar and sends alert messages to the
Driver Interface Unit (DIU) located in the dash via the vehicle’s J1939 data link. The DIU uses a combination of visual and audible alerts to
warn the driver of approaching hazards, or if following distances are too close for the current speed of the vehicle.
Bendix™ SmartCruise® (SC)
Bendix™ SmartCruise is a feature of the VS-400’s Forward Looking Radar that controls the adaptive cruise control function of the engine.
When enabled, SmartCruise will override the engine’s set cruise speed in order to maintain a safe following distance when approaching
slower moving traffic. The vehicle’s engine must support and be enabled for adaptive cruise control in order for the VORAD® SmartCruise®
function to operate. Contact your vehicle OEM for information on the engine’s adaptive cruise control function.
Side Object Detection (SOD)
The VORAD Side Object Detection (SOD) is a stand-alone system that utilizes a close proximity pulse radar sensor to detect the presence
of a vehicle in a lane adjacent to the host vehicle. The SOD includes its own Driver Display Unit (DDU) to report object detection and
Diagnostic Trouble Code (DTC) information to the driver. The system may be installed separately, or as an option for the VS-400 system.
J1939 (CAN) Data Link
The J1939 data link is an SAE defined high-speed Controller Area Network (CAN) used to provide a means of communication between
compliant electronic devices on the vehicle. The data link consists of a twisted pair of wires running within the vehicle’s electrical harness
that connects all J1939 compatible devices together in a chain.
Each end of the data link chain is terminated with a 120-ohm resistor to reduce electrical noise, or interference. The two terminating
resistors also provide an easy means to test the integrity of the link by producing a combined 60-ohm link resistance that can be measured
at any connection point on the link with a digital ohmmeter. Contact the vehicle OEM for information on the J1939 data link wiring and
terminations.

System Operation
Overview
This section covers the operation of the Side Object Detection (SOD) system. The Side Object Detection system is a stand-alone system
which can be installed as an all-on feature for the Bendix™ VORAD® VS-400 Forward Looking system. It is powered independently from the
forward looking system and utilizes its own Driver Display Unit which is typically located on the windshield pillar.
System Power Up
When the vehicle’s ignition is turned to the ON position, the SOD display will power up by initially illuminating both the red and yellow lamps,
indicating the system is performing its self test. Once the self test is complete and no objects are within a 15 foot radius of the sensor, the
red lamp turns off while the yellow lamp remains illuminated, indicating the system is operational.

Normal Operation
When an object is detected within the sensor’s detection zone, the driver display illuminates the red detect lamp. During normal operation,
the display will toggle between illuminating either the yellow or the red lamps, but never both at the same time (See SOD Failure Diagnostic
Procedure).
Alert Tone
If the turn signal is active when an object is detected, the Driver Display Unit will sound an alert tone. An alert tone is heard only once each
time the turn signal is activated. The sensor is wired to the turn signal on the same side of the vehicle in which the sensor is mounted (ie:

1. Forward Looking Radar Alignment
Alignment
WARNING
The alignment of the Forward Looking Radar is critical to the correct operation of the Bendix™ VORAD® VS-400 system. Improper
alignment can cause the system to improperly detect objects in the vehicle’s path. Every precaution should be taken to ensure
the VS-400 system alignment (both horizontal and vertical), is correct.
Alignment of the Forward Looking Radar is a repetitive process of adjusting the vertical and horizontal axis using the bracket screws. The
vertical alignment must be completed with a digital level. The horizontal alignment is started by referencing the FLR against fixed positions
on the bumper and using a digital level. The horizontal alignment is completed by performing a calibration procedure with the Service
Ranger 3 diagnostic software while driving the unit equipped with the VORAD system.
Note: The vehicle must be parked on a level surface. If the vehicle is on an angled surface, then level compensations must be made to
ensure proper alignment.
Below are steps for a typical alignment procedure. Other companies, such as Hunter Engineering Company (11250 Hunter Drive,
Bridgeton, MO 63044, 314-731-3020), can also be contacted to establish alignment using other professional alignment equipment.
2. Vertical Alignment
The steps for vertical alignment are as follows:
1.
Hold a digital level against the flat surface of the mounting bracket.
2.
Use a 5/32" Allen wrench to loosen the locking screws.

3. Horizontal Alignment
The Forward Looking Radar must be facing straight ahead (azimuth) of the vehicle in order to optimally detect objects in the vehicle path.
1.Select two truck reference points that are identical and symmetrical about the truck centerline. Ensure the reference points
are equally aligned. Items such as fenders and headlights should not be damaged or distorted; otherwise the alignment will be
inaccurate.
2. Center a 4'-6' (1-2m) straight edge across a flat surface of the forward looking radar bracket.
3. Measure the distance between the reference points and the face of the straight edge.
4. Use a 5/32" Allen wrench to loosen the locking screws.
Note: Failure to loosen both locking screws will result in damage to the alignment bracket.
5. Adjust the alignment screw until the two measurement points are equal within +/- 0.1" (2.54mm).
6. Once the measurements are equal for both of the reference points, tighten the locking screws.
7. Check both the vertical and horizontal alignment:
a.
b.
Re-measure the reference points to ensure they are equal.
Use the digital level to verify the vertical alignment is still face down 0° from vertical ± .2°.
Note: The illustration below shows a typical mounting and mounting bracket. The design may vary.

Calibrating the FLR Horizontal Alignment
After the physical horizontal alignment has been conducted on the chassis, there is a calibration procedure that should be implemented
prior to delivery to the customer. This can also be performed as a service function at any point in time, if required. The calibration procedure
requires the use of diagnostic software on a mobile computer that can be operated in the cab while the vehicle is in motion.
CAUTION
This procedure requires two people. The driver must not attempt to perform the calibration procedure while driving the vehicle.
In order to perform this procedure, the VORAD equipped vehicle must be traveling on a straight road at a speed above 30 mph behind a
target vehicle traveling in the same lane. The Bendix™ VORAD®-equipped vehicle should be placed into SmartCruise® mode behind this
target vehicle. If the VORAD® system is not Bendix™ SmartCruise® adaptive cruise control-equipped, position the vehicle manually 200 to
300 feet behind the target vehicle. At highway speeds, this can be approximated by the VORAD® DIU displaying a following distance of "2
seconds" or "3 seconds."
Double click on the option for "VORAD® VS-400 Alignment Tests."
Follow the steps shown on the diagnostic software.
Continue to run the truck for a period of time (2-5 min), monitoring the azimuth value. As long as the vehicle the VORAD® system is tracking
is in the same lane, the azimuth position should be 0°, but fluctuations in driving techniques may cause the vehicle to drift +/- 0.3°. If this
value cannot be consistently kept, click the "Reset" button again and monitor the azimuth position. If the position is consistently more than
0.5° or less than -0.5°, the FLR horizontal alignment must be adjusted based on the average azimuth position.
Note: For best results it is recommended that the driver perform the alignment test for 2-5 minutes to verify correct tracking of vehicles in
the same lane.
39

3 continued
Fine-Tuning the Horizontal Alignment
If the alignment function in the diagnostic software continuously shows an azimuth value greater than 0.5° or less than -0.5°, then the FLR
needs to be physically adjusted in the horizontal direction beyond that already completed.
Center FLR Azimuth Position (FLR aligned correctly)
If the alignment function consistently shows an azimuth value of 0° +/- 0.5° when tracking a vehicle in the same lane, then the FLR is
properly centered. In this case, the FLR does not need to be further aligned and the procedure is complete.
40
Appendix
General Information
3 continued
Negative Azimuth Adjustment (FLR too far to the left)
If the alignment function shows a positive value, then the FLR is adjusted too far to the left, when looked at from the driver's seat. The radar
needs to be adjusted to the driver's right. To accommodate this, adjust the horizontal alignment screw by turning it in a clockwise direction,
when viewed from the front of the vehicle. Each full rotation of the alignment screw adjusts for approximately 0.2° of azimuth position from
the alignment function. For example, if the azimuth position was 0.5°, then the alignment screw should be adjusted 21/2 turns clockwise.
After adjustment of the FLR, perform the calibration procedure again to verify proper alignment.
41
Appendix

3 continued
Positive Azimuth Adjustment (FLR too far to the Right)
If the alignment function shows a negative value, then the FLR is adjusted too far to the right, when looked at from the driver's seat. The
radar needs to be adjusted to the driver's left. To accommodate this, adjust the horizontal alignment screw, by turning it in a counterclockwise direction, when viewed from the front of the vehicle. Each full rotation of the alignment screw adjusts for approximately 0.2° of
azimuth position from the alignment function. For example, if the azimuth position was -0.5°, then the alignment screw should be adjusted
21/2 turns counter-clockwise.
After adjustment of the FLR, perform the calibration procedure again to verify proper alignment.

4. Component Power Supply Test
Overview
The base Bendix™ VORAD® VS-400 system consists of two components, the FLR and DIU. Both should be powered by the main ignition
power supply (12 Vdc). If one of these components is incorrectly connected to constant battery power or a secondary ignition source other
than the main ignition power supply bus, there is the potential for J1939 communication Diagnostic Trouble Code (DTC) between the FLR
and the DIU. These include, but are not limited to, Diagnostic Trouble Codes (DTCs) 32 and 33. If these Diagnostic Trouble Codes (DTCs)
appear after the installation of a new VS-400 system or if the system is suspected of having this problem, perform this test to verify proper
ignition power source to the FLR and the DIU.
Verifying Ignition Power to the DIU
Step
Procedure
A
1. Vehicle Ignition: Key-OFF, Engine-OFF.
2.Disconnect the 8-way connector from the back of the VS-400 Driver Interface Unit (DIU).
3. Measure for zero voltage on pins 4 and 5 on the harness connector.
a. If the voltage is 0.5 volts or less.
i. Proceed to Step B.
b.
If voltage is greater than 0.5 volts but less than battery voltage.
i. Test Failed. Check DIU power supply wiring for sources of stray voltage or shorts to voltage.
c.

Verifying Component Power Up Timing
Verify the DIU and FLR are wired to the same ignition source. If either component is wired to a secondary ignition source with a delay, one
of the components may set a Diagnostic Trouble Code (DTC) as a result of the other(s) delayed power cycle.
Step
E
Procedure
1. Key-OFF. Let the truck sit for two minutes to allow time for the ECU's to completely power down.
2.Disconnect the 10-way connector from the back of the FLR and add a test lamp to ignition power pin 10.
If the test lamp requires a ground pin, use pin 9 or chassis ground.
CAUTION
Be careful not to spread pins on the FLR harness connector while performing this test.
3.Disconnect the 8-way connector from the back of the DIU and add a test lamp to power pin 4. If the test lamp
requires a ground pin, use pin 5 or ground the lamp to chassis ground.
CAUTION
Be careful not to spread pins on the DIU harness connector while performing this test.
4.
While viewing both test lamps, turn the ignition key on to verify that both lamps light at the same time.
a.If there is a noticeable delay before one lamp lights, the power source for the delayed light could
be a secondary delayed ignition supply.
i.Correct the wiring by connecting the appropriate component to the main ignition power
supply bus.
b.
If the lamps light simultaneously.
