engine is cranked, then turn itself off if no malfunctions are present.
However, if after 15 seconds theService engine soonlight blinks eight
times, it means that the vehicle is not ready for I/M testing. See the
Readiness for Inspection/Maintenance (I/M) testingin the
Maintenance and Specificationschapter.
