Retrieving Codes Using ECU:
System configuration codes and fault codes
are displayed through the dash ABS warning
light as a series of blinked sequences. The fault
codes can be accessed by properly grounding
Terminal 18 in the X1 connector found on the
ABS ECU module. The Bendix ABS ECU
module is located under the shift selector
panel. On the back of the ECU locate the
black X1 connector, pin 18. Ground pin 18 as
described by inserting a wire at the rear of the
connector. Pin 18 is located in the bottom right
corner (labeled ABS Warning).
NOTE
System configuration codes are
sequences of six blinked digits while
fault codes are sequences of two
blinked digits. Refer to an authorized
Bendix service center for a list of blink
code sequences. If grounding out is not
done correctly for a specific readout,
stop then start the procedure again.
NOTE
All blink codes are displayed by the
ABS warning light only.
The system is capable of performing several
diagnostic mode functions. After ignition on,
a two second delay must be observed prior to
grounding.
Active code retrieval:
ground 1 time.
Inactive code retrieval:
ground 2 times.
Clearing active codes:
ground 3 times.
System configuration check:
ground 4
times.
Dynamometer test mode:
ground 5 times.
Reconfigure ECU: ground 7 times.
NOTE
Reconfigure Mode is entered by
grounding prior to “ignition on.” Once
ignition is on, stop grounding, then
ground 7 times.
ATC System:
The ATC system improves traction on
slippery or unstable road surfaces by
limiting excessive drive wheel slip. This is
accomplished two ways, limiting engine torque
to the drive wheel or engaging a brake to the
spinning drive wheel. During normal operation
engine torque is unaffected. The ATC system
works in conjunction with the ABS Electronic
Control Unit. The ECU monitors tone ring
speed of the drive wheel in relation to the
other wheels. If a speed differential occurs in
the drive wheel, the ECU enters Automatic
Traction Control mode.
During an ATC event, the ECU will
automatically react to optimize traction and
safety if the motorhome encounters a slippery
road surface. Engine torque is normally
reduced to limit drive wheel slip.
NOTE
The ATC system is always active.
ATC reacts to drive wheel slip by:
Reducing engine torque to the drive
wheel if road speed is above 25 mph.
Reducing engine torque and activating
drive axle brake controls if road speed
is below 25 mph. If the brake control
activates, it remains active regardless
of road speed.
