I/M Readiness function is used to check the 
operations of the emission systems. It is an 
excellent function to use prior to having a vehicle 
inspected for compliance to a state emissions 
program. 

Some latest vehicle models may support two types 
of I/M Readiness tests: 

A.  Since DTCs Cleared - indicates status of 

monitors since the DTCs are erased. 

B.  This Drive Cycle - indicates status of 

monitors since the beginning of the current 
drive cycle.

The O2 Monitor Test function allows retrieval and 
viewing of O2 sensor monitor test results for the 
most recently performed tests from the vehicle's 
on-board computer. 

The O2 Monitor Test function is not supported by 
vehicles which communicate using a controller 
area network (CAN). For O2 Monitor Test results 
of CAN-equipped vehicles, please refer to 
“On-Board Mon. Test”. 

The data can be saved to the SD card, or be 
printed.
