Special Trailer ABS (Without PLC)
Option
If a trailer does not have PLC, but it does
have ABS that is powered through an
optional second trailer connector (ISO
3731) and that trailer ABS is designed to
control the Trailer ABS Warning Lamp in
the cab and the vehicle has been ordered
with the option to turn on this lamp for
these types of trailers, then this lamp will
turn on when that trailer ABS has a system
problem. This should be checked by a
dealer as soon as possible. The Trailer
ABS Warning Lamp will not turn on for the
power-on test when connected to these
types of trailers.
NOTE
Very few trailers built before 03/01/2001
have this option. Trailers built after
03/01/2001 are built with PLC technology.
Advanced ABS with Stability
Control
What you need to know about your
vehicle's braking, traction, and stability
control features.
Electronic Stability Control is a feature that
reduces the risk of rollovers, jackknifing,
and other loss of control situations. ESC
features include Roll Stability Program
(RSP) and Yaw Control.
During operation, the ECU of the Bendix
®
Advanced ABS system constantly
compares performance models to the
vehicle’s actual movement, using the
wheel speed sensors of the ABS system,
as well as lateral, yaw, and steering angle
sensors. If the vehicle shows a tendency to
leave an appropriate travel path, or if
critical threshold values are approached,
the system will intervene to assist the
driver.
ESC may reduce the vehicle speed
automatically. To minimize unexpected
deceleration and reduce the risk of a
collision the operator must:
• Avoid aggressive driving
maneuvers, such as sharp turns or
abrupt lane changes at high speeds,
which might trigger the stability
system.
• Always operate the vehicle safely,
drive defensively, anticipate
obstacles and pay attention to road,
weather, and traffic conditions. ABS,
ATC, and ESC stability systems are
no substitute for prudent, careful
driving.
Roll Stability Program
Bendix
®
Roll Stability Program (RSP), an
element of the overall ESC system,
addresses rollover conditions. In the case
of a potential roll event, the ECU will
override the throttle and quickly apply
brake pressure at all wheel ends to slow
the vehicle combination. The level of
braking application during an RSP event
will be proportional to roll risk.
A Real World Example of How the
RSP System Operates
Excessive speed for road conditions
creates forces that exceed the threshold at
which a vehicle is likely to rollover on a
higher-friction surface. The system
automatically reduces engine torque and
applies the service brakes (based on the
projected rollover risk) to reduce the
