The vehicle may not pass
inspection if:
.The malfunction indicator lamp is
on with the engine running, or if
the light does not come on when
the ignition is turned to ON/RUN
while the engine is off.
.The critical emission control
systems have not been
completely diagnosed by the
system. This can happen if the
battery has recently been
replaced or if the battery has run
down. The diagnostic system
evaluates critical emission
control systems during normal
driving. This can take
several days of routine driving.
If this has been done and the
vehicle still does not pass the

prepare the vehicle for
inspection.
