1993 PONTIAC GRAND-PRIX service reset

Anti-Lock Brake System Warning
Light (OPTION)
With anti-lock, this light will go on
when you start your engine and it will
stay on for three seconds. That’s
normal.
If the light doesn’t come on,
have it fixed
so it will be ready to warn
you if there is a problem.
If the light stays on or comes on when
you’re driving,
stop as soon as possible
and turn the key off. Then start the
engine to reset the system. If the light
still stays
on, or comes on again while
you’re driving, your Pontiac needs
service. Unless the regular brake system
warning light
is also on, you will still
have brakes, but not anti-lock brakes.
If
the regular brake system warning light
is also on, see the Index under Brake
System Warning Light.
If the anti-lock brake system warning
light ever flashes, your anti-lock brake
system is still working but needs service
as soon as possible.
