BULLETIN

TSB REVISION NOTICE:
The information updated in this TSB is red
and underlined.
The On±Board Diagnostic (OBDII) system is designed to monitor the performance of
emission±related components and report any detected abnormalities in the form of
Diagnostic Trouble Codes (DTCs). Since the various components need to be monitored
during different driving conditions, the OBDII system is designed to run separate
monitoring programs called Readiness Monitors. Many state Inspection and
Maintenance (I/M) programs require that vehicles complete their Readiness Monitors
prior to beginning an emissions test.
The current status of the Readiness Monitors can be seen by using the Toyota Diagnostic
Tester with version 9.0 software (or newer), or a generic OBDII Scantool.
To view the Readiness Monitor status using the Toyota Diagnostic Tester, select ªMonitor
Statusº from the Enhanced OBDII Menu.
A status of ªcompleteº indicates that the necessary conditions have been met to run the
performance tests for the related Readiness Monitor.
The Readiness Monitor will be reset to ªincompleteº if:
ECU has lost power (battery or fuse).
DTCs have been cleared.
The conditions for running the Readiness Monitor have not been met.
In the event that any Readiness Monitor shows ªincomplete,º follow the appropriate
Readiness Monitor Drive Pattern to change the readiness status to ªcomplete.º
Refer to the Readiness Monitor Drive Pattern Application Table to determine which
drive pattern should be followed.
