READINESS MONITOR DRIVE PATTERN
1. PURPOSE OF READINESS TESTS
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.
To view the status, enter the following menus: Powertrain / Engine and ECT / Monitor / Current
Monitor / Current.
When the Readiness Monitor status reads 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 complete before beginning emission tests.
The Readiness Monitor will be reset to 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 incomplete, follow the appropriate Readiness Monitor Drive
Pattern to change the status to complete.
CAUTION:
Strictly observe posted speed limits, traffic laws, and road conditions when performing these drive
patterns.
