Retrieve 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. Some latest vehicle models may support two types of I/M Readiness tests:
A. Since DTCs Cleared – indicates status of the monitors since the DTCs are erased.
B. This Drive Cycle – indicates status of monitors since the beginning of the current drive cycle.
