I/M Monitors (Emissions)
Inspection / Maintenance Monitors provide a snapshot of the Emission
System operations by indicating that the I/M Monitors are
Ready
or
Not
Ready
. For an I/M Monitor to be
Ready
, the vehicle must have com-
pleted a drive cycle (been driven long enough under proper conditions
to have completed a drive cycle). A Monitor must be listed as
Ready
to
pass an emissions test. If an I/M Monitor is
Not Ready,
it is because a
drive cycle has not completed.
