I/M refers to Inspection and Maintenance that is legislated by the Government to
meet federal clean-air standards. I/M Readiness indicates whether or not the
various emissions-related systems on the vehicle are operating properly and are
ready for Inspection and Maintenance testing.
The purpose of the I/M Readiness Monitor Status is to indicate which of the
vehicle’s Monitors have run and completed their diagnosis and testing, and
which ones have not yet run and completed testing and diagnosis of their
designated sections of the vehicle’s emissions system.
The I/M Readiness Monitor Status function also can be used (after repair of a
fault has been performed) to confirm that the repair has been performed
correctly, and/or to check for Monitor Run Status.
Tap [I/M Readiness] on the Job Menu to start checking. After checking all I/M
readiness status, the screen will output the result:
