4 OnSide Warnings, Cautions and Operating Guidelines
4.1 Driver-Related Information
WARNING
The OnSide Blind Spot Detection (BSD) system is merely a driver’s assist tool and does not engage in
all driving situations or traffic, weather or road conditions. The driver always bears ultimate responsibility
for ensuring that the vehicle is driven safely and that applicable laws and road traffic regulations are
followed. Failure to do so can result in serious personal injury or death and/or severe property damage.
The driver is responsible for understanding the operation and limitations of the OnSide BSD system
before operating the vehicle. Failure to do so can result in serious personal injury or death and/or severe
property damage. Please refer to the OnSide Blind Spot Detection (BSD) Driver’s Tips available at
www.wabco-na.com/literature for additional information on the correct operation and understanding of
the situations in which the system may not provide assistance.
WARNING
The OnSide Blind Spot Detection (BSD) system was designed, manufactured and installed as an
operator assistant. This system is not intended to replace good attentive driving behaviors and practices
which may change based upon traffic and road conditions. Use of OnSide cannot compensate for a
driver that is tired, distracted, inattentive or impaired by fatigue, drugs or alcohol. As always, it is the
driver’s responsibility to:
Use safe driving techniques.
Exercise proper judgement for the traffic, road and weather conditions.
Maintain a safe distance between vehicles and respect speed limits.
React to road conditions to maintain control of the vehicle.
Failure to do so can result in serious personal injury or death and/or severe property damage.

8
OnSide Warnings, Cautions and Operating Guidelines
WARNING
Always pay attention to the road when driving, whether the OnSide system is engaged or not. Distraction
comes in many forms and can take your focus from the task of driving. Exercise good judgment and do
not let other activities divert your attention away from the road. Many local governments have enacted
laws regarding driver distraction. Become familiar with the local laws in your area. To avoid distracted
driving, always keep your eyes on the road, hands on the wheel, and mind on the drive.
Do not use a phone in demanding driving situations. Use a hands-free method to place or receive
necessary phone calls.
Watch the road. Do not read, take notes, or look up information on phones or other electronic
devices.
Designate a front seat passenger to handle potential distractions.
Become familiar with vehicle features before driving, such as programming favorite radio stations
and adjusting climate control and seat settings. Program all trip information into any navigation
device prior to driving.
Wait until the vehicle is parked to retrieve items that have fallen to the floor. Driving while distracted
can result in serious personal injury or death and/or severe property damage.
WARNING
The OnSide Blind Spot Detection System is designed as a warning system and thus, will not actively
intervene to prevent contact with other vehicles, persons or objects. The system is not intended as
a substitute for proper lane change procedures. Alerted by an OnSide warning, the driver must take
corrective measures to avoid an imminent side collision.
Drivers must remain aware of their surroundings by using all available mirrors before changing lanes.
Never rely solely on the system. OnSide is a radar-based system and has a defined detection zone.
Vehicles outside of the detection zone will not be detected by the system. In some situations, not every
vehicle or object will be detected by the radar even within the detection zone.
By design, the OnSide BSD system will not warn of the following:
Any stationary object, such as parked cars, trees, walls, etc.
Vehicles moving in the opposite direction.
Smaller objects, such as bicycles, animals or pedestrians.
OnSide will not offer alerts when the tractor is traveling below 15 mph (24.2 km/h).

OnSide Warnings, Cautions and Operating Guidelines
4.2 Environment-Related Information
WARNING
The OnSide BSD radar sensor performance may be degraded or completely disabled under these
conditions:
Damaged fascia.
Poor weather conditions such as heavy snow, ice, heavy rain or road spray.
Dirt, mud or insect buildup.
If the system is not functioning correctly or as expected, have the OnSide system inspected to correct
the issue. Whether or not the system is working correctly, it is the driver’s responsibility to react to
changing road conditions to maintain vehicle control. Failure to do so can result in serious personal injury
or death and/or severe property damage.
4.3 System Functions
The OnSide BSD System is designed as a warning system and thus, will not actively intervene to prevent
contact with other vehicles, persons or objects. The system is not intended as a substitute for proper lane
change procedures. Alerted by an OnSide warning, the driver must take corrective measures to avoid an
imminent side collision. Drivers must remain aware of their surroundings by looking and using all available
mirrors before changing lanes. Never rely solely on the system.
The OnSide BSD system is passive, there is no switch or button to turn the system on or off. The system
powers up when the ignition is cycled on, at this time the OnSide BSD system will perform a bulb check
and flash the OnSide BSD LED indicator. The OnSide BSD system automatically becomes active at speeds
above 15 mph (24.2 km/h). Its blind spot detection alerts (visual and/or audible) are available as soon as
the vehicle reaches 15 mph (24.2 km/h).
If the vehicle is equipped with OnGuard and uses the WABCO OnGuard dash display, there will be addi-
tional visual and audible warnings through the display.
Whether or not the system is engaged, it is the driver’s responsibility to react to changing road conditions
to maintain vehicle control. Failure to do so can result in serious personal injury or death and/or severe
property damage.

OnSide Warnings, Cautions and Operating Guidelines
4.4 System Malfunction Information
WARNING
Modifications to electronic components and their software as well as wiring can impair their function and/
or the function of other networked components. In particular, systems relevant to safety could also be
affected. As a result, these may no longer function as intended and/or jeopardize the safe operation of
the vehicle. There is an increased risk of an accident and injury. Never tamper with the wiring as well as
electronic components or their software. You should have all work to electrical and electronic equipment
carried out at a qualified specialist workshop.
If there is a malfunction and the system cannot provide assistance, the LED indicator (mounted on the
A-pillar) may not illuminate at all, may continuously be illuminated or may blink intermittently. If the vehicle
is equipped with the WABCO OnGuard dash display, during a malfunction OnSide, may not be listed/recog-
nized in the OnGuard display "SYSTEMS DETECTED" start-up menu. When there is a BSD system mal-
function, it may not warn correctly when a moving vehicle is detected in the passenger side blind spot zone.
Whether or not the system is functioning correctly, it is the driver’s responsibility to react to changing road
conditions to maintain vehicle control. Failure to do so can result in serious personal injury or death and/or
severe property damage.

OnSide® BSD Introduction
5 OnSide®BSD Introduction
5.1 System Description
OnSide Blind Side Detection (BSD) is an advanced driver assistance system that supports drivers in
overtaking and lane change maneuvers to help avoid side collisions. The OnSide system becomes active
at speeds above 15 mph (24.2 km/h). Once active, the system constantly monitors the vehicle’s passenger
side blind spot and warns of moving vehicles appearing in the vehicle’s passenger side blind spot. The
system utilizes a short range radar sensor mounted on the right side of the truck cabin to constantly monitor
the vehicle’s passenger side blind spot. When the OnSide BSD system detects a moving vehicle in the
monitored blind spot, the system provides a visual warning from the OnSide BSD LED indicator mounted
in the passenger side A-pillar (close to the side view mirror). This visual warning will occur with and without
turn signal activation.
OnSide was designed to be a standalone system; no other WABCO systems are required to be installed on
the vehicle for OnSide to function. OnSide is compatible with other WABCO systems such as OnGuard.
5.1.1 Dash Displays
5.1.1.1 WABCO OnGuard®Display
If the vehicle is equipped with a WABCO OnGuard display, when the vehicle is traveling above 15 mph
(24.2 km/h) with the right turn signal activated, and the OnSide BSD system detects a moving vehicle in
the passenger side blind spot, the OnGuard display will provide audible and visual alerts to warn the driver
that the adjacent lane is not clear. These alerts are in addition to the visual warning provided by the OnSide
BSD LED indicator.
Some installations have a WABCO OnGuard display mounted under/behind the dash for
additional audible warnings only.
5.1.1.2 OEM Integrated Instrument Cluster Display
Some OnSide BSD systems may use the vehicle’s integrated instrument cluster display to provide
additional warnings.
For these vehicles, consult OEM reference materials for display operation, diagnostics and repair
instructions.

OnSide® BSD Introduction
5.2 System Components
5.2.1 OnSide BSD Radar Sensor
Fig. 5.1
4016834a
The OnSide BSD system utilizes a 24 GHz short-range radar sensor (Figure 5.1) mounted on the right
side of the truck cabin to constantly monitor the vehicle’s passenger side blind spot zone. The radar
continuously detects a wide variety of stationary and moving objects in the vehicle’s passenger side blind
spot, while the algorithm filters out the stationary objects. This allows the system to warn the driver only of
moving objects (objects traveling in the same direction).
Fig. 5.2
4016835a
The radar sensor has a 160-degree field of view and reach of up to 33 ft. rearward and 13 ft. forward
(Figure 5.2).

OnSide® BSD Introduction
5.2.2 OnSide BSD Radar Fascia
Fig. 5.3
4016836a
The OnSide BSD radar sensor mounts on the passenger side of the truck. When the OnSide BSD radar
sensor is mounted on the outside of the fairing or step area, it is covered by a fascia to provide protection
against the elements and damage (Figure 5.3).
5.2.3 OnSide BSD LED Indicator
Fig. 5.4
4016837a
Fig. 5.5
No Vehicle Detected Vehicle Detected
Fig. 5.5
The OnSide BSD system constantly monitors the vehicle’s passenger side blind spot zone for moving
vehicles. When the system detects moving vehicles appearing in the vehicle’s passenger side blind spot,
it warns the driver using an LED warning lamp (Figure 5.4) mounted on the passenger side A-pillar (close
to the rear view mirror). When OnSide is active, the LED warning lamp will illuminate (Figure 5.5) and will
remain on until the detected vehicle exits the blind spot zone.

If the vehicle is equipped with OnGuard and uses the WABCO OnGuard display (Figure 5.6) during the
key-on ignition cycle, OnSide should be listed in the WABCO display “SYSTEMS DETECTED” start-up
menu (Figure 5.7).
Fig. 5.7
4016841a
The WABCO OnGuard display also provides additional visual (Figure 5.8) and audible warnings. The
additional audible and visual warnings from the display occur if the right turn signal is activated while there
is a moving vehicle detected in the passenger side blind spot zone.
Fig. 5.8
4016842a
Some vehicles may have a display mounted behind/under the dash for audible warning
purposes only.

Fig. 5.14
4016848a
Not all vehicles will use the WABCO OnSide BSD harness; some may use an OEM harness. Please see
the OEM reference materials for harness information. If the vehicle does use the WABCO OnSide BSD
harness (Figure 5.14), it will have the BSD radar sensor connector and BSD LED indicator connector, and
the turn signal input relay will be tapped to the harness. The harness will have a ground splice inside. The
harness power (ignition) wire, ground wire, right turn input signal wire, and J1939 CAN High and Low wires
will be spliced into the vehicle harness. The locations of the splices will vary depending on the installer and
vehicle.

Diagnostics, Troubleshooting and Testing
6 Diagnostics, Troubleshooting and Testing
OnSide BSD system does not have any type of warning to indicate the system has been
disconnected or has a failure. The only way to determine that there is an OnSide BSD
system issue is if it fails to perform correctly at start up and/or fails to perform correctly while
driving. The system does not feature any type of manual diagnostic or blink code mode. If
an issue with the OnSide BSD system is suspected, check for system faults or DTCs using
TOOLBOX™ 12.9 Software or newer.
6.1 OnSide BSD System Functional Checks
When the ignition is turned on, the OnSide BSD LED indicator will illuminate briefly for a bulb check
(Figure 6.1) and then go out (Figure 6.2), indicating the system is ready for use.
Fig. 6.1
4016850a
Fig 6.2
4016837a
Bulb Check or Vehicle Detected Normal or No Vehicle Detected
If the vehicle is also equipped with OnGuard and uses the WABCO OnGuard display, during the ignition
key-on cycle, "OnSide" should be shown on the display in the "SYSTEMS DETECTED" start-up menu
(Figure 6.3).
Fig. 6.2
Fig. 6.3
4016852a
OnSide Recognized
If the OnSide BSD LED indicator did not illuminate briefly and/or "OnSide" was not recognized in the
WABCO OnGuard display start-up menu (Figure 6.4), a display issue, an OnSide BSD system issue, or
J1939 circuit issue is indicated.

Diagnostics, Troubleshooting and Testing
Once the OnSide BSD LED indicator bulb check has been performed, drive the vehicle above 15 mph
(24.2 km/h) with a moving vehicle in your passenger side "blind spot zone" (Figure 6.5) and verify that
the OnSide BSD LED indicator is illuminated. As the vehicle exits the passenger side blind spot zone, the
OnSide BSD LED indicator should go out. The OnSide BSD LED indicator should always perform in this
manner, with or without turn signal activation.
Fig. 6.5
4016853a
For vehicles equipped with a WABCO OnGuard display, when the vehicle is traveling above 15 mph
(24.2 km/h), the right turn signal is activated, and a moving vehicle is detected in the blind spot zone, the
display will also provide warnings. In addition to the warning from the OnSide BSD LED indicator, there
will be an audible chirp heard and a visual "Blind Spot Alert" (Figure 6.6) warning message shown on the
display. The "chirps" and "Blind Spot Alert" warning message will continue as long as the vehicle is traveling
above 15 mph (24.2 km/h), the right turn signal is activated, and there is a moving vehicle in the passenger
side blind spot zone.
Fig. 6.6
4016854a
If the right turn signal is not activated, there will be no indication (audible or visual) from the
WABCO OnGuard display indicating that there is a moving vehicle in your passenger side
blind spot zone.
6.2 System Visual Inspection
Perform a visual inspection of the OnSide BSD system before proceeding with any diagnostics or repairs.
Ensure that the OnSide BSD radar sensor and fascia are not missing or visibly damaged, and are
mounted correctly and securely.
Verify that the OnSide BSD radar sensor and fascia are clean, with no buildup of snow, ice, dirt/mud,
insects or debris.
Ensure there are no loose or corroded connections, particularly where the OnSide BSD system harness
may have been spliced into the vehicle harness.

19
Diagnostics, Troubleshooting and Testing
Inspect the wiring for cut or frayed areas that could cause an open circuit or a short to the vehicle body,
which would result in a short-to-ground condition.
Verify the OnSide BSD LED indicator is mounted correctly and shows no visible sign of damage.
Verify the WABCO display (if equipped) is mounted correctly and shows no visible sign of damage.
Confirm the WABCO display is the correct part number and has the correct software.
