READINESS MONITOR DRIVE PATTERN PURPOSE OF READINESS TESTS
HINT: Many state Inspection and Maintenance (I/M) programs require the status of vehicle Readiness Monitor to show Complete before beginning emission tests.
CAUTION: Strictly observe posted speed limits, traffic laws, and road conditions when performing these drive patterns. NOTICE: These drive patterns represent the fastest method of satisfying all conditions necessary to achieve complete status for each specific Readiness Monitor. In the event of a drive pattern being interrupted (possibly due to factors such as traffic conditions), the drive pattern can be resumed. In most cases, the Readiness Monitor will still achieve complete status upon completion of the drive pattern. To ensure completion of the Readiness Monitors, avoid sudden changes in vehicle load and speed (driving up and down hills and/or sudden acceleration).
