5.6 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.
