Dodge Ram 1500 Owner's Manual page 315

The system's pump motor runs during an ABS stop to
provide regulated hydraulic pressure. The pump motor
makes a low humming noise during operation. This is
normal.
The Anti-Lock Brake System conducts a low-speed self-
test at about 10 mph. If you have your foot lightly on the
brake while this test is occurring you may feel slight
pedal movement. The movement can be more apparent
on ice and snow. This is normal.
The Anti-Lock Brake System pump motor runs during
the self-test at 10 mph and during an ABS stop. The
pump motor makes a low humming noise during opera-
tion, which is normal.
When you are in a severe braking condition involving
use of the Anti-lock Brake System, you will experience
some pedal drop as the vehicle comes to a complete stop.
This is the result of the system reverting to the base brake
system and is normal.
Engagement of the Anti-lock Brake System may be
accompanied by a pulsing sensation. You may also hear a
clicking noise. These occurrences are normal, and indi-
cate that the system is functioning.
ABS Warning Light
The Anti-lock Brake System includes an amber warning
light. When the light is illuminated, the Anti-lock Brake
System is not functioning. The system reverts to standard
non-anti-lock brakes.
WARNING!
Pumping of the anti-lock brakes will diminish their
effectiveness and may lead to an accident. Pumping
makes the stopping distance longer. Just press firmly
on your brake pedal when you need to slow down or
stop.
