POWER-UP-SELF-TEST

The Power-Up-Self-Test is a self diagnostic check of the
® ®
Bendix Wingman ACB system that automatically runs
15 seconds after the engine starts, while the vehicle is
parked and when the cruise control switch is "on". It runs
for approximately 5 seconds, checking the engine and
brake systems to make sure they are functioning properly
for ACB to operate. It will stop if the vehicle is moving or the
cruise control switch is turned "off". While the test is running
normally, the driver should hear a short set of beeping
alerts and may get a distance alert message. During the
test, the "Target Detected" icon in the instrument cluster
may illuminate. This is normal. If Bendix
will not function properly, a long warning beep will sound
to alert the driver and a trouble code will be logged in the
system. The Power-Up-Self-Test is available on all Bendix
®
Wingman ACB versions manufactured after 2009. See
Figure 8 for software version identifi cation.

TROUBLE CODE SELF CLEARING
Many of the diagnostic trouble codes will clear when the
cause of the problem is corrected. When the technician
troubleshoots a diagnostic trouble code, it is recommended
®
that the Bendix ACom
the diagnostic trouble codes as directed by the repair
procedure.
Some codes will clear immediately and the functionality
will resume. Some codes will clear after powering off the
ignition for about 15 seconds and then turning it back on.
Other codes will clear after the engine runs for about 15
seconds.
If the vehicle's cruise control can be engaged, that indicates
all Wingman ® ACB trouble codes have been cleared.

SENSOR INTERCHANGEABILITY

Many variables must be considered when determining
whether or not a sensor can be relocated from one vehicle
to another vehicle. They include, but are not limited to,
® ®
Bendix ESP stability system, the instrument cluster, the
vehicle ECU, the engine and the transmission. Contact
the Bendix Tech Team at 1-800-AIR-BRAKE to determine
if this is a viable option. Warning! Do not interchange
sensors without contacting Bendix fi rst!

FOLLOWING DISTANCE ADJUSTMENT
SWITCH (OPTIONAL)
Wingman ® ACB will operate normally if not equipped with
a following distance (time gap) adjustment switch. The
vehicle will follow the forward vehicle at the distance,
depending on the confi guration, chosen by the fl eet owner
or customer. See section BENDIX
AND ADJUSTMENTS.
If the vehicle is equipped with the following distance
adjustment switch and the following distance does not
change, the switch, wiring, or a controller on the vehicle
should be checked using the diagnostic procedures
® ACB
described by the vehicle manufacturer. The ACB radar
sensor receives the driver's desired following distance on
the J1939 data communication link from a controller on the
®
vehicle. No diagnostic trouble code will be set if the vehicle
is not equipped with a following distance adjustment switch.
