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.

PRELIMINARY CHECK
Fuel level should be between
1/4 and 3/4
Visually inspect for presence
of Fuel/Gas Cap
DO NOT TIGHTEN OR REMOVE!
PRESSURIZE EVAP SYSTEM (System Integrity Check)
This test checks for leaks in the canister and fuel tank sides. The CCV and Air Inlet Lines will be checked
separately.
A) Clamp the air drain hose on the charcoal canister with the supplied hose pliers from the EVAP System
Pressure Test Kit.
B) Locate the vapor pressure sensor. If the vapor pressure sensor has two hoses connected to it,
disconnect the hose between the air drain hose fitting at the vapor pressure sensor and plug the hose.
C) Connect the pressure supply hose from the Pressure Test Kit to the Green EVAP System Service Port
located on the EVAP Purge VSV line in the engine compartment.
D) Using the directions on the inside of the EVAP System Pressure Test Kit lid, pressurize the EVAP
system. Once pressurized, turn off the pump and seal the system (Pressure Hold Switch to ªClosedº
and Vent Switch to ªClosed).
E) After 30 seconds, note the pump pressure gauge reading and the Scan Tool vapor pressure
sensor reading.
F) Compare the readings to one of the four conditions listed below and proceed as directed.
DO NOT PROCEED! NG
OK
SCAN TOOL SETUP
A) Connect Scan Tool to DLC3 on vehicle.
B) Go to the SETUP menu and select UNIT CONVERSION.
C) Under VAPOR PRESSURE, Select ABS for absolute pressure, and mmHg for millimeters of mercury.
This is to match the Repair Manual specifications.
D) Go back to FUNCTION SELECT menu and select ENHANCED OBD II.
E) Select NORMAL MODE. Then select CURRENT DATA and USER SELECT.
F) Using the arrow key, select VAPOR PRESS from the DATA LIST and select YES.
G) Press ENTER. You will now be able to monitor the Vapor Pressure Sensor reading.
START
If vehicle is ECHO, go directly to ªECHO Canister and Tank Leak Checkº on page 14.

Key Registration
This function allows the registration of additional key codes for transponder keys
(Master/Sub Keys) using a Registered Master Key.
Key Code Erasure
This function allows the user to erase all the key codes for transponder keys except
the Registered Master Key used during this function.
Auto Registration Closure
This function allows the user to close ªAuto Registration Modeª when less than three
keys have been registered.
NOTE:
When a new ECU is installed, it is in the ªAuto Registration Modeº from the factory.
This allows Transponder Keys to automatically register as they are inserted into the
Ignition Cylinder. After three Transponder Keys are registered, the ECU closes ªAuto
Registration Modeº. See the Repair Manual for further details.

This section provides the procedures necessary to access the IMMOBILIZER KEY CODE
UTILITY functions. Refer to the instructions below.
Before any IMMOBILIZER KEY CODE UTILITY function can be performed, the type of
Transponder Key must be verified. The following steps show how to verify the
Transponder Key type.
1. Connect the Diagnostic Tester to DLC3 and press the (ON) key.
2. Insert a Registered Master Key (Black Key Head) into the ignition key cylinder and
turn to the ON position.
HINT:
A Registered Master Key is required for KEY REGISTRATION, KEY CODE ERASURE,
and AUTO REGISTRATION CLOSURE. A Sub Key (Grey Key Head) will not perform
these functions.

Is the cylinder(s) identified by the DTC(s) misfiring?
If YES ± Go to Step 3.
If NO ± Follow normal diagnostics for applicable DTC in Technical Information System
(TIS) in applicable Repair Manual:
Diagnostics: SFI: P030#.
3. Swap suspect ignition coil(s) from cylinder that is misfiring to cylinder that is
not misfiring.
4. Using Diagnostic Tester, confirm that misfire is now occurring in cylinder that has
suspect ignition coil(s). Has misfire followed swapped ignition coil(s)?
If YES ± Replace ignition coil(s) and go to Step 5.
If NO ± Follow normal diagnostics in Technical Information System (TIS) for
applicable Repair Manual:
Diagnostics: SFI: P030#.
5. Confirm misfire has been eliminated (0% at all times) using Diagnostic Tester while
engine is idling.
NOTE:
If misfire percent is any value other than 0% at any time, then that cylinder is misfiring. Repair
