4.5 Read I/M Readiness Status Data
I/M Readiness option allows to view a snapshot of the operations for the emission system on
OBDII/EOBD vehicles.
I/M Readiness is a useful function used to check if all monitors are OK or N/A. The vehicle’s
computer performs tests on the emission system during normal driving conditions. After a specific
amount of drive time (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.
