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 with Diagnostic Trouble Codes (DTCs).
Since various components need to be monitored during different driving conditions, the OBD II system
runs separate monitoring programs called readiness monitors.
The hand-held tester's software must be version 9.0 or newer to view the readiness monitor status.
From the ºENHANCED OBD IIº menu, select ºMONITOR STATUSº to view the readiness monitor sta-
tus.
A generic OBD II scan tool can also be used to view the readiness monitor status.
When the readiness monitor status reads ºcompleteº, the necessary conditions have been met for run-
ning performance tests for that readiness monitor.
HINT:
Many state Inspection and Maintenance (I/M) programs require a vehicle's readiness monitor status to show
ºcompleteº.
The readiness monitor will be reset to ºincompleteº if:
The ECM has lost battery power or blown a fuse.
DTCs have been cleared.
The conditions for running the readiness monitor have not been met.
If the readiness monitor status shows ºincompleteº, follow the appropriate readiness monitor drive pat-
tern to change the status to ºcompleteº.
CAUTION:
Strictly observe posted speed limits, traffic laws, and road conditions when performing these drive
patterns.
NOTICE:
The following drive patterns are the fastest method of completing all the requirements necessary for
making the readiness monitor status read ºcompleteº.
If forced to momentarily stop a drive pattern due to traffic or other factors, the drive pattern can be
resumed. Upon completion of the drive pattern, in most cases, the readiness monitor status will
change to ºcompleteº.
Sudden changes in vehicle load and speed, such as driving up and down hills and/or sudden accel-
eration, hinder readiness monitor completion.
