cause this alert to be activated.

Grades should be approached normally, with the
appropriate gear selected and at a safe speed. Cruise
control should NOT be used on downhill grades.
When the system detects brake overuse, depending on the
vehicle manufacturer, a text message will be displayed on
the dashboard and an audible alert will be activated. The
driver should intervene immediately.

Figure K18 – Brake Overuse Warning

•

Once the brake overuse alert is activated, certain
driver interventions that cancel cruise control – like
stepping on the brake pedal or switching off cruise – will
discontinue the alert. Following an overuse alert, the
driver should not reset cruise control for at least 20
minutes. This gives the brakes time to cool down.

ACB REQUIRES
DRIVER INTERVENTION

Figure K17 – Stationary Vehicle Braking (SVB) Alert Displayed

If the driver chooses to reset cruise control during that
20 minute period, Fusion system interventions will
be limited to de-throttling and engine retarder only.
The system will automatically disable all Wingman
Fusion system foundation brake applications for
at least 20 minutes. If the system does not detect
a driver intervention within 15 seconds after the
brake overuse alert sounds, it will shut itself off and
set a Diagnostic Trouble Code (DTC). The driver will
continue to receive alerts, but all Wingman Fusion
system interventions (de-throttling, engine retarder
or brake applications) will be disabled until the next
ignition cycle.

Appendix K

75

NOTE: In all cases, the driver still has the ability to
apply the foundation brakes if necessary. The driver
should take care since overheated brakes may reduce
the vehicle’s braking capability. (Refer to Appendix
B7.0).

LANE DEPARTURE WARNING
(LDW) ALERT

The Bendix Wingman Fusion system has the ability
to warn the driver if the vehicle is not tracking in the
intended roadway path. In most vehicle applications the
LDW system is enabled above 37 mph. The driver should
immediately correct the vehicle tracking and maintain the
correct position in the lane.

OVERSPEED ALERT & ACTION (OAA)

The Bendix Wingman Fusion system has the ability to
warn the driver if the vehicle’s speed exceeds the posted
legal limits. The Overspeed Alert & Action is enabled
when the vehicle is traveling greater than 5 mph / 8 kph
from the posted limit. The driver should immediately
reduce speed to the posted legal limit.
When the vehicle exceeds the posted speed limit by
5 mph / 8 kph, an audible alert will sound to alert the driver.
If the vehicle speed exceeds 10 mph/16 kph over the posted
speed limit, an audible alert signals the driver to slow down
and a one-second de-throttle of the engine will occur.
International travel: When changing between regions
which post speeds in miles and those which post in
kilometers, the speed limit sign recognition feature
will not function until the correct U.S./Metric selection
has been made.

K1.14 BENDIX® WINGMAN® FUSION™
SYSTEM DIAGNOSTIC
TROUBLE CODES

K1.16 ALERT VOLUME

The Bendix® Wingman® Fusion™ system is monitored and
if any malfunction is detected, a Diagnostic Trouble Code
(DTC) will be set and the driver will be alerted. The exact
alert given depends on the vehicle manufacturer: refer to
the vehicle operator’s manual and Sections 3 and 4.

K1.15 RADAR SENSOR
INTERCHANGEABILITY
Many variables must be considered when determining
whether or not the radar sensor can be relocated from one
vehicle to another vehicle. They include, but are not limited
to, the version of the Bendix® ESP® stability system used
on the vehicle, the instrument cluster, the vehicle Electronic
Control Unit (ECU), the engine and the transmission.
Contact the Bendix Tech Team at 1-800-AIR‑BRAKE
(1-800-247-2725), option 2, to determine if this is a viable
option.

Do not interchange radar sensors without contacting
Bendix first.

For Bendix Wingman Fusion systems installed on vehicles
with alerts that come directly through the instrument cluster,
audible alert levels are pre-set at the factory and cannot be
turned off, but the volume may be adjustable, depending
on the OE. (However, where the Bendix™ Driver Interface
Unit (DIU™) is used, volume adjustment is permitted.)

K1.17 POTENTIAL FALSE ALERTS
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 Bendix
Wingman Fusion system. (Refer to Appendix J.)

K1.171 POTENTIAL STATIONARY
OBJECT FALSE ALERTS
In certain unusual traffic or roadway conditions, the Fusion
system may issue a false alert. While eliminating all false
alerts is not possible, if false alerts occur too frequently
(more than twice a day), service the system at the earliest
opportunity.

K1.172 POTENTIAL FALSE - OR MISSING SPEED SIGN ALERTS
Some road speed signs may not be able to be recognized
– or be recognized incorrectly – by the system.

APPENDIX L - MAINTENANCE SECTION
L1.1 GENERAL SAFETY GUIDELINES
Refer to Page 2 of this Service Data Sheet for the General
Safety Guidelines.

L1.2 SYSTEM PREVENTIVE MAINTENANCE
The Bendix ® Wingman ® Fusion ™ system is relatively
maintenance free. The key items to keep the system
functioning properly include:
1. Keep the radar front – and windshield – clean and free
of obstructions.
2. Inspect for any damage to the bumper, radar, or camera
to ensure that the alignment has not been compromised.
Never use the radar unit as a step. NOTE: If the radar
sensor was originally installed behind a panel, check
the panel for damage, etc. that may impact the radar’s
performance before reinstalling. Replace the panel, if
necessary, with an original OEM supplied panel. Do not
paint over the panel.
3. Perform appropriate inspections of the braking system
as required by the manufacturer to ensure brakes are
in proper working order.
4. Ensure that the tires are properly inflated and that
adequate tread is present.

Inspections – The driver should inspect the radar
and camera mounting brackets regularly and keep the
windshield and bumper locations clear of any mud, snow,
ice build-up, or other obstructions. The installation of
aftermarket deer guards, bumper guards, snow plows, or
similar potential obstructions is not recommended, and
could impair the operation of the radar.

Damage/Tampering – In cases where the bumper,
radar and/or windshield have sustained any damage, are
misaligned, or if the device is suspect for tampering, do
not use the active cruise control until the vehicle has been
repaired and the radar re-aligned. In addition, an indicator
on the dash typically will illuminate if the system detects
any of these conditions. Consult the vehicle’s operator’s
manual or contact Bendix for more information.
NOTE: Any vehicle trouble code that disables vehicle
cruise control will also cause a DTC in the Bendix Wingman
Fusion system.
