I/M Readiness

The I/M Readiness (Inspection / Maintenance) function is used to view a snapshot of the operations for the emission system on OBD II vehicles.

✓I/M Readiness is a very useful function. To guarantee no faults exist make sure all monitors are ok or n/a and no DTC’s exist.

✓Refer to the vehicles service manual for the drive cycle operation.

✓During normal driving conditions, the vehicle’s computer scans the emission system. 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

4 4 or not as well as detecting out of range values. 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.

✓Depending on vehicle, disconnecting or a discharged battery may erase DTCs and clear monitor status.

✓Monitors may be cleared by:

❒Erasing codes

❒Vehicle control modules losing power

✓I/M Readiness can be done with the KOER or KOEO.
