READINESS MONITOR DRIVE
PAT T E R N
1. PURPOSE OF READINESS TESTS
• The On-Board Diagnostic (OBD II) system is
designed to monitor the performance of emission-
related components, and indicate any detected
abnormalities with DTCs (Diagnostic Trouble Codes).
Since various components need to be monitored in
different driving conditions, the OBD II system is
designed to run separate monitoring programs called
Readiness Monitors.
• The intelligent tester's software must be version 9.0 or
newer to view the Readiness Monitor status. To view
the status, select the following menu items:
DIAGNOSIS / ENHANCED OBD II / MONITOR INFO
/ MONITOR STATUS.
• When the Readiness Monitor status reads COMPL
(complete), the necessary conditions have been met
for running the performance tests for that Readiness
Monitor.
• A generic OBD II scan tool can also be used to view
the Readiness Monitor status.
HINT:
Many Inspection and Maintenance (I/M) programs
require a vehicle's Readiness Monitor status to show
COMPL before beginning emission tests.
The Readiness Monitor will be reset to INCMPL
(incomplete) if:
• The ECM has lost battery power or broken a fuse.
• DTCs have been cleared.
• The conditions for running the Readiness Monitor
have not been met.
If the Readiness Monitor status shows INCMPL, follow
the appropriate Readiness Monitor Drive Pattern to
change the status to COMPL.
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).
