engine and restart. If it remains illuminated, it
means the ABS is disabled and should be
serviced immediately to restore the benefits of
the anti-lock feature. Normal braking is not
affected unless the red BRAKE system warning
light is also illuminated.
ABS has self-check capabilities. As described
above, the system turns on the ABS light each
time you start your engine. After the engine is
started and the ABS light turns off, the system
performs another test the first time the vehicle
reaches 4-9 mph (6-15 km/h). The system turns
on the ABS pump motor for approximately 1/2
second. At this time, a mechanical noise may be
heard. This is a normal part of the self-check
feature. If a malfunction is found during this
check the ABS light will come on.
On vehicles equipped with an antilock braking
system (ABS), a noise from the hydraulic pump
motor and pulsation in the pedal may be
observed during ABS braking events. Pedal
pulsation coupled with noise while braking
under panic conditions or on loose gravel, wet
or snowy roads is normal and indicated proper
functioning of the vehicle's antilock brake
system. If the vehicle has continuous vibration or
shudder while braking, mainly in the steering
wheel, the vehicle most likely needs service.

detrimental effects of popular mobile radio
transmitting equipment installed on vehicles
equipped with the Anti-lock Brake System if
