BENDIX GSBC SYSTEM FEATURES CONT.
TOWED VEHICLES WITHOUT ABS
Some towed vehicles, especially older trailers built before 2001, may not be
equipped with their own ABS systems. Use extra care when towing a vehicle that
is not equipped with its own ABS system. During emergency braking or braking on
slippery surfaces, a non-ABS equipped trailer could lose its lateral stability and swing
out if its wheels lock up. Use your mirrors to watch carefully and adjust your brake
applications as necessary to keep your tractor and the non-ABS-equipped towed
vehicle in line with each other. Tractor ABS helps reduce the tendency to jackknife,
but it cannot prevent a non-ABS equipped trailer from swinging out.
AUTOMATIC TRACTION CONTROL ATC
Bendix® ATC is a feature for vehicles equipped with a Bendix® GSBC® system that
controls wheel spin during vehicle acceleration to improve traction.
ATC may intervene automatically and apply braking pressure to a spinning wheel,
thus transferring engine power to other drive wheels that have better traction. This
feature is active only at low vehicle speeds.
If ATC is active and all of the drive wheels begin to spin, the Bendix ATC system may
reduce engine throttle to improve traction at all of the drive wheels.
Operating Vehicles with ATC
If the drive wheels begin to lose traction during acceleration, the ATC system may
engage automatically to assist the driver in accelerating the vehicle.
NOTE: For vehicles equipped with an inter-axle dierential lock switch, you should
consult the vehicle Operator’s Manual for additional information about that feature.
Typically, the driver is advised to stop the wheels from spinning and engage the inter-
axle dierential lock switch, but you should always follow the specic instructions
given in the vehicle’s Operator’s Manual for this feature and the vehicle’s particular
conguration.
