(b) If the test value is between the minimum test limit 

and maximum test limit, the component is 
functioning normally. If not, the component is 
malfunctioning. The test value is usually significantly 
higher or lower than the test limit. If the test value is 
on the borderline of the test limit, the component will 
malfunction in the near future.
HINT:
The monitor result might on rare occasions be 
PASS even if the malfunction indicator lamp (MIL) is 
illuminated. This indicates the system malfunctioned 
on a previous driving cycle. This might be caused by 
an intermittent problem.

READINESS MONITOR DRIVE 
PATTERN

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 during 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 state 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 blown 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).
