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 “Monitor
Status” from the Enhanced OBDII Menu.
A status of “complete” 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 “incomplete” if:
SECU has lost power (battery or fuse).
SDTCs have been cleared.
SThe conditions for running the Readiness Monitor have not been met.
In the event that any Readiness Monitor shows “incomplete,” follow the appropriate
Readiness Monitor Drive Pattern to change the readiness status to “complete.”
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:
SThese drive patterns represent the fastest method to satisfy all necessary
conditions which allow the specific Readiness Monitor to complete.
SIn 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 “complete.”
STo ensure rapid completion of Readiness Monitors, avoid sudden changes in
vehicle load and speed (driving up and down hills and/or sudden acceleration).

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 50_F (10_C) 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:
SDo not allow the Throttle Position (TP) to exceed 30%.
SDrive with smooth throttle operation and avoid sudden acceleration.
c. Stop the vehicle and let the engine idle for 3 – 5 minutes.
d. Repeat steps “b” and “c” once.
If readiness status does not switch to “complete,” ensure preconditions are met, turn the
ignition OFF, then repeat steps “b” through “d.”
NOTE:
The readiness status may not switch to “complete” after the first drive pattern trip if a
Pending Code has been set (first trip for a two–trip DTC).
SPending Codes are available from the DTC Info Menu in Enhanced OBDII.
SPending Codes indicate a POTENTIAL problem was detected. A second trip is
needed to confirm the DTC prior to diagnosis.
SOnce a second trip is completed, a current DTC will be stored.

* For 2002 MY and later vehicles: The readiness test can be completed in cold ambient conditions
(less than 14_F / –10_C), if the drive pattern is repeated a second time after cycling the ignition OFF.
Drive Pattern Procedure
Connect the OBDII Scantool to DLC3 to check monitor status and preconditions.
Note the IAT (Intake Air) value during engine startup. The driving time must be adjusted
during step “a” based upon IAT (Intake Air) value at startup.
a. Drive the vehicle at 40 – 55 mph (64 – 88 km/h) for the time described below:
SIf IAT (Intake Air) was less than 50_F (10_C) when the engine was started,
drive for 7 minutes.
SIf IAT (Intake Air) was greater than 50_F (10_C) when the engine was started,
drive for 3 minutes.
b. Drive the vehicle at 35 – 45 mph (56 – 72 km/h) for approximately 7 minutes.
NOTE:
SDrive with smooth throttle operation.
SAvoid sudden acceleration.
SAvoid sudden deceleration as much as possible with the throttle fully closed.
If readiness status does not switch to “complete,” ensure preconditions are met, turn the
ignition OFF, then repeat steps “a” and “b.”
NOTE:
The readiness status may not switch to “complete” after the first drive pattern trip if a
Pending Code has been set (first trip for a two–trip DTC).
SPending Codes are available from the DTC Info Menu in Enhanced OBDII.
SPending Codes indicate a POTENTIAL problem was detected. A second trip is
needed to confirm the DTC prior to diagnosis.
SOnce a second trip is completed, a current DTC will be stored.

SAltitude is 7800 feet (2400 m) or less.
IMPORTANT:
A cold soak must be performed prior to conducting the drive pattern to complete the
Internal Pressure Readiness Monitor.
Cold Soak Procedure
1a. Start the engine and allow ECT (Coolant Temp) to reach 176_F (80_C) or greater.
(This can be done by letting the engine idle or by driving the vehicle.)
1b. Let the vehicle cold soak for 8 hours or until the difference between IAT (Intake
Air) and ECT (Coolant Temp) is less than 13_F (7_C).
HExample 1
SECT (Coolant Temp) = 75_F (24_C).

SDifference between ECT (Coolant Temp) and IAT (Intake Air) is 15_F (8_C).
⇒The monitor will not run because the difference between ECT (Coolant
Temp) and IAT (Intake Air) is greater than 13_F (7_C).
HExample 2

SRelease the pressure in the fuel tank by removing and then reinstalling the fuel tank
cap.
SStart the engine and begin driving as directed.
NOTE:
SDo not turn the ignition off until the drive pattern is complete.
SDrive on smooth roads to reduce excessive fuel sloshing.
2a. Start the engine and as soon as safely possible begin driving at approximately 45
mph (72km/h) for 5 minutes. (See illustration on previous page.)
2b. Drive the vehicle at approximately 25 mph (40 km/h) for 15 minutes and include a
minimum of two stops for approximately 30 seconds. (See illustration on previous
page.)
The monitor should complete within approximately 20 minutes. If it does not, ensure
preconditions are met and repeat the drive pattern process beginning with the Cold Soak
Procedure.
NOTE:
