Braking force is applied at a level which
minimizes the stopping distance while
maintaining as much lateral stability as
possible.
ABS Warning Light:
The ABS will perform a dash indicator lamp
check and self-diagnostic test each time the
ignition is switched to the on position.
When the ignition is turned on, the ABS
indicator illuminates momentarily (3
seconds) verifying the self-diagnostic
test. If the ABS indicator light remains
on, or illuminates while the motorhome
is being operated, this indicates a fault
in the anti-lock brake system. This fault
will not affect normal service braking.
The motorhome will need to go to a
service center to repair the problem.
INFORMATION
If a fault code occurs, call a Bendix
service locator at 1-800-247-2725 and
take the motorhome to the nearest
repair facility.
ABS Diagnostic
If the ABS light on the dash comes on it
indicates that a fault has occurred with the Anti-
lock Brake System only. Normal braking is not
affected but the motorhome will need to go to
a service center. The service center can retrieve
ABS diagnostic fault codes.

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.
