READINESS MONITOR DRIVE PATTERN
1. PURPOSE OF THE READINESS TESTS
The On-Board Diagnostic (OBD II) system is designed to monitor the performance of emission-re-
lated components and report any detected abnormalities in the form of Diagnostic Trouble Codes
(DTCs). Since the various components need to be monitored during different driving conditions, the
OBD II system is designed to run separate monitoring programs called Readiness Monitors. Many
state Inspection and Maintenance (I/M) programs require that vehicles complete their Readiness Mon-
itors prior to beginning an emissions test.
The current status of the Readiness Monitors can be seen by using the hand-held tester with version
9.0 software (or newer), or a generic OBD II Scan tool.
To view the Readiness Monitor status using the hand-held tester, select ºMonitor Statusº from the En-
hanced OBD II Menu.
A status of ºcompleteº indicates that the necessary conditions have been met to run the performance
tests for the related Readiness Monitor.
The Readiness Monitor will be reset to ºincompleteº if:
ECM has lost power (battery or fuse).
DTCs have been cleared.
The conditions for running the Readiness Monitor have not been met.
In the event that any Readiness Monitor shows ºincomplete,º follow the appropriate Readiness Monitor
Drive Pattern to active the monitor and change the readiness status to ºcomplete.º
CAUTION:
Strictly observe of posted speed limits, traffic laws, and road conditions when performing these
drive patterns.
NOTICE:
These drive patterns represent the fastest method to satisfy all necessary conditions which allow
the specific readiness monitor to complete.
In the event that the drive pattern must be interrupted (possibly due to traffic conditions or other fac-
tors) the drive pattern can be resumed, and in most cases, the readiness monitor will still set to ºcom-
pleteº.
To ensure rapid completion of readiness monitors, avoid sudden changes in vehicle load and speed
(driving up and down hills and/or sudden acceleration).
