6. I/M Readiness
I/M Readiness function is used to check the operations of the emission
systems. It is an excellent function to use prior to having a vehicle inspected
for compliance to a state emissions program.
Some latest vehicle models may support two types of I/M Readiness tests:
A. Since DTCs Cleared - indicates status of monitors since the DTCs are
erased.
B. This Drive Cycle - indicates status of monitors since the beginning of
the current drive cycle.
