anti-lock brake System
The trailer’s anti-lock brake system (ABS) includes
wheel speed sensors, tone rings, warning lamp,
and electronic and pneumatic control modules.
The ABS continuously monitors wheel speed
and controls braking during extreme braking
applications. When the Electronic Control Unit
(ECU) detects an extreme braking application, the
unit activates the appropriate pneumatic control
valve, and brake air pressure is controlled. If the
ABS malfunctions, the trailer will have non-ABS-
assisted braking. However, it is important to have
the system repaired immediately.
Vehicle safety is
your responsibility!
WaRNING:
The abS indicator light located at the trailer’s
left rear corner should turn on and off when
electrical power is initially applied to the anti-
lock brake system. If the lamp does not turn on,
it may be defective and must be repaired. If the
lamp turns on and remains on while power is
continuously applied, the abS system must be
inspected and repaired by a qualified service
facility. failure to take action can result in
property damage, serious injury, or death.
you must operate your vehicle as safely as
possible. While the abS can help you bring
your vehicle to a controlled, safe stop in severe
braking situations, abS cannot compensate
for excessive speed, inattentive driving, or
improper handling of your vehicle. Safety is up
to you.
