• Retrieving I/M Readiness Status
I/M Readiness function is used to check the operations of the
Emission System on OBD2 compliant vehicles. It is an excellent
function to use prior to having a vehicle inspected for compliance to
a state emissions program.
CAUTION - By clearing trouble codes you also clear the readiness
status for the individual emission system readiness tests. In order to
reset these monitors, the vehicle must be driven through a complete
drive cycle with no trouble codes in memory. Times for reset vary
depending on vehicle.
Some latest vehicle models may support two types of I/M Readiness
tests:
1. Since DTCs Cleared - indicates status of the monitors since the
DTCs are erased.
2. This Drive Cycle - indicates status of monitors since the beginning
of the current drive cycle.
