Summary
As part of an enhanced emissions test for Inspection & Maintenance (I/M), some States may require the System Readiness Test (SRT) status be checked. - The SRT is used to indicate whether the engine control module (ECM) has completed self diagnosis of major emissions systems and components. - In these instances the State may require completion of the SRT before permitting the emissions inspection to proceed. Refer to this Bulletin for further details.
