(each monitor has specific driving conditions and time required), the
computer’s monitors decide if the vehicles emission system is working
correctly.
When the monitor’s status is:
● OK - vehicle was driven enough to complete the monitor.
● INC (Incomplete) - vehicle was not driven enough to complete the
monitor.
● N/A (Not Applicable) - vehicle does not support that monitor.
There are two types of I/M Readiness tests:
●Since DTCs Cleared - shows status of the monitors since the DTCs
were last cleared.
● This Drive Cycle - shows status of monitors since the start of the
current drive cycle.
