Troubleshooting Wiring Harness; Wingman Acb Sensor Mounting And Installation; Vehicle Applications; Acb Sensor Mounting - BENDIX Wingman ACB Service Data

If the J1939 HIGH and J1939 LOW wiring circuits are
reversed, communication over the entire J1939 link
will not be lost. Only those devices that are outside
of the failure point from other devices will not receive
or be able to transmit data messages.
3. Check for corroded or damaged wiring connector
problems such as opens or shorts to voltage or ground.
If the connector terminals are corroded, this may be
an indication of water intrusion into the wiring system
and possibly into the radar sensor. Replacement of
the entire harness is recommended. If the terminals
of the radar sensor are corroded, replacement of radar
sensor is recommended.
4. Check for other J1939 devices which may be inhibiting
J1939 communication. The service technician should
consult the vehicle manufacturer's procedures for
other J1939 troubleshooting procedures. The device's
power should be removed and measurements made at
the ECU pins for shorts to ground and power pins and
resistance between the J1939 HIGH or J1939 LOW
input circuits.
5. Unplug the radar sensor. With the ignition switch off,
measure the resistance (ohms) using a multimeter
between harness pins 2 and 3. The reading should be
approximately 60 ohms. If it is not, the vehicle wiring
should be investigated using procedures described by
the manufacturer.
6. Unplug the radar sensor. With the ignition switch
off, using a multimeter, measure the resistance in
ohms, between harness pins 2 and ground. The
measurement should indicate an open circuit or very
high resistance. If this is not the case, the vehicle
wiring should be investigated using procedures
described by the manufacturer.
7. Unplug the radar sensor. With the ignition switch
off, using a multimeter, measure the resistance in
ohms, between harness pins 3 and ground. The
measurement should indicate an open circuit or very
high resistance. If this is not the case, the vehicle
wiring should be investigated using procedures
described by the manufacturer.

TROUBLESHOOTING WIRING HARNESS

All wire harness connectors must be properly seated to
maintain environmental seals. Push the mating connector
until it seals with a click. When replacing an ACB radar
sensor, check that the wire harness connector is free of
corrosion before plugging into a new sensor. Check for
corroded or damaged wiring connector problems such as
opens or shorts to voltage or ground.

If the connector terminals are corroded, this may be an
indication of water intrusion into the wiring system and
possibly into the radar sensor. Replacement of the entire
harness is recommended. If the terminals of the sensor are
corroded, replacement of radar sensor is recommended.
WINGMAN ® ACB SENSOR MOUNTING AND
INSTALLATION

VEHICLE APPLICATIONS

The Bendix ® Wingman ® ACB sensor can be mounted and
installed only on vehicles that have Bendix
already installed. At this time ACB cannot be retrofi t onto
vehicles, even if that vehicle is equipped with the Bendix
ESP ® stability system.

ACB SENSOR MOUNTING

When mounting an ACB sensor, the wire harness connector
should always point down. The ACB assembly is mounted
to the front of the vehicle using an adjustable bracket.
This adjustable bracket allows for the ACB sensor to be
properly aimed laterally and vertically to maximize ACB
system performance.
The ACB assembly should always be mounted in the
original OEM location. If this location is not in the center of
the vehicle, the mounting offset will need to be programmed
through Bendix ® ACom ® software. (See CHECK LATERAL
ALIGNMENT section.)
For proper operation of your Bendix
system, adhere to the following guidelines:
• The Bendix ® Wingman
be rigidly installed on the vehicle following all OEM
recommended torque specifi cations.
• The Bendix ® Wingman ®
installed in the original OEM designated location.
• The ACB sensor cover should always be installed. This
helps protect components such as the connector and
wiring harness from road debris.
• The ACB assembly must be oriented so that the electrical
connector points down. Mounting the radar upside
down will impair performance signifi cantly.
• The radar's fi eld of view must NOT have interference
from any other vehicle components such as bumpers,
cow-catcher bumpers, engine blankets, seasonal
decorations or any other commonly mounted front-of-
vehicle components. (NOTE: If original OEM installation
was behind a translucent panel, this panel must be
reinstalled. Check the panel for damage or scratches
that may impact the performance of ACB. Replace the
panel, if necessary, with an original OEM supplied panel.
Do not paint over the panel.
