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.

NOTE:
A generic OBDII Scantool can be used in place of the Toyota Diagnostic Tester.
CAUTION:
Strict observance of posted speed limits, traffic laws and road conditions are
required when performing these drive patterns.
NOTE:
These drive patterns represent the fastest method to satisfy all necessary
conditions which allow the specific Readiness Monitor to complete.
In the event that the drive pattern must be interrupted (possibly due to traffic
conditions or other factors) the drive pattern can be resumed and, in most cases,
the Readiness Monitor will still set to ªcomplete.º
To ensure rapid completion of Readiness Monitors, avoid sudden changes in
vehicle load and speed (driving up and down hills and/or sudden acceleration).

Preconditions
The monitor will not run unless:
MIL is OFF.
Altitude is 7800 feet (2400 m) or less.
IAT (Intake Air) is 14F (±10C) or greater.
Drive Pattern Procedure
Connect the OBDII Scantool to the DLC3 connector to check monitor status and
preconditions.
a. If IAT (Intake Air) is less than 50F (10C) when starting the engine, idle the
engine for approximately 10 minutes.
b. Drive the vehicle at 43 ± 56 mph (70 ± 90 km/h) for a period of 3 ± 5 minutes.
NOTE:
Do not allow the Throttle Position (TP) to exceed 30%.
Drive with smooth throttle operation and avoid sudden acceleration.
c. Stop the vehicle and let the engine idle for 3 ± 5 minutes.
d. Repeat steps ªbº and ªcº once.
If readiness status does not switch to ªcomplete,º ensure preconditions are met, turn the
ignition OFF, then repeat steps ªbº through ªd.º
NOTE:
The readiness status may not switch to ªcompleteº after the first drive pattern trip if a
Pending Code has been set (first trip for a two±trip DTC).
Pending Codes are available from the DTC Info Menu in Enhanced OBDII.
Pending Codes indicate a POTENTIAL problem was detected. A second trip is
needed to confirm the DTC prior to diagnosis.
Once a second trip is completed, a current DTC will be stored. Readiness
