The I/M Readiness function is used 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.
√ I/M Readiness function is performed with the KOER or KOEO.
