READINESS MONITOR DRIVE PATTERN

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 DTC (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.



To view the status, enter the following menus: Powertrain/Engine and ECT/Monitor/Status 2.



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.



current driving cycle is displayed.

CAUTION: Strictly observe posted speed limits, traffic laws, and road conditions

when performing these drive patterns.

NOTE:

These drive patterns represent the fastest method of satisfying all
conditions necessary to achieve complete status for each specific
Readiness Monitor.
