Dodge 2009 Viper - Manual (Page 104)

This light also illuminates at vehicle start-up to indicate
that the ABS self-check is in process. If the light remains
on after start-up, or turns on and remains on at road
speeds, it may indicate a system malfunction or that the
system is inoperative. In this case, the system reverts to
standard non-anti-lock brakes. If this occurs, safely bring
the vehicle to a complete stop as soon as possible and
cycle the ignition key to attempt to reset the ABS. If the
light remains on, see your authorized dealer immediately
to have the system serviced. Furthermore, if the red
BRAKE Warning Light and the amber ABS Warning
Light are on, and the parking brake is fully released, see
your authorized dealer immediately.
WARNING!
If the ABS and/or Brake Warning Lights illuminate,
please seek service immediately! Your vehicle will
have diminished braking capability and control if
ABS and/or service brake systems are not working
properly. Have your brake system serviced immedi-
ately.
Malfunction Indicator Light (MIL)
The Malfunction Indicator Light (MIL) is part
of an onboard diagnostic system called OBD.
The OBD system monitors engine control sys-
tems. The light will turn on when the key is in
the ON/RUN position before engine start. If the light
does not come on when turning the key from OFF/LOCK
to ON/RUN, have the condition checked promptly.
