12. O2S TEST RESULT
INTRODUCTION
The O2S TEST RESULT refers to the results of the engine con-
trol module (ECM) when it monitors the oxygen sensor (O2S),
and it can be read using the hand-held tester or the generic
OBD II scantool. Based on this, you can find the O2S's condi-
tions.
The ECM monitors the O2S in the various items. You can read
the monitor result (TEST DATA) of each monitor item using the
O2S TEST RESULT. However, the output value of the TEST
DATA is the latest ºsnapshotº value that is taken after monitor-
ing and therefore is not dynamic.
In this repair manual, the description of the O2S TEST RESULT
(for O2S related DTCs) are written in a table.
This table consists of 5 items:
(1) TEST ID (a code applied to each TEST DATA)
(2) Description of TEST DATA
(3) Conversion Factor (When Conversion Factor has a
value written in the table, multiply the TEST DATA
value appearing on the scan tool by the Conversion
Factor value. The result will be the required value.)
(4) Unit
(5) Standard Value
If the TEST DATA value appearing on the scan tool is out of the
standard value, the O2S is malfunctioning. If it is within the stan-
dard value, the O2S is functioning normally. However, if the val-
ue is on the borderline of the standard value, the O2S may mal-
function very soon.
HOW TO READ O2S TEST RESULT USING HAND-HELD
TESTER
(a) Connect the hand-held tester to the DLC3.
(b) On the tester screen, select the following menus: DIAG-
NOSIS/CARB OBDII/O2S TEST RESULT. A list of the
O2S equipped on the vehicle will be displayed.

13. CHECKING MONITOR STATUS
NOTICE:
The Monitor Status is not applicable to the heated oxygen
sensor (HO2S). The HO2S status can be checked with O2S
TEST RESULT.
(a) INTRODUCTION
The purpose of the monitor result (mode 6) is to allow ac-
cess to the results for on-board diagnostic monitoring
tests of specific components/systems that are not contin-
uously monitored. Examples are catalyst, EVAP and ther-
mostat.
The monitor result allows the OBD scan tool to display the
monitor status, test value and test limit. The monitor sta-
tus indicates whether the component is functioning nor-
mally or not (PASS or FAIL). The test value is the value
that was used to determine the monitor status. When the
test value is inside the test limit, the ECM determines the
component is functioning normally (PASS). If the test val-
ue is outside the test limit, the ECM determines the com-
ponent is malfunctioning (FAIL).
A problem in these components/systems can be found by
comparing the test value and test limit. The monitor result
information is included under MONITOR RESULTº in the
DTC sections.
(b) PROCEDURE
NOTICE:
The monitor result and test value are cleared when the igni-
tion switch is turned OFF.
(1) Connect the hand-held tester to the DLC3.
(2) Turn the ignition switch ON.
(3) Clear the DTCs.
(4) Run the vehicle in accordance with the applicable
drive pattern described in READINESS MONITOR
DRIVE PATTERN (see page DI-30).
(5) Select from the tester menus: DIAGNOSIS, EN-
HANCED OBD II, MONITOR INFO and MONITOR
RESULT. The monitor result appears after the com-
ponent name.
INCMP: The component has not been monitored
yet.
PASS: The component is functioning normally.
FAIL: The component is malfunctioning.
(6) Confirm that the component is set to either PASS or
FAIL.

READINESS MONITOR DRIVE PATTERN
1. PURPOSE OF THE READINESS TESTS

The On-Board Diagnostic (OBD II) system is designed to monitor the performance of emission-re-
lated 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
OBD II 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 Mon-
itors prior to beginning an emissions test.

The current status of the Readiness Monitors can be seen by using the hand-held tester with version
9.0 software (or newer), or a generic OBD II Scan tool.

To view the Readiness Monitor status using the hand-held tester, select ºMonitor Statusº from the En-
hanced OBD II Menu.

A status of ºcompleteº 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 ºincompleteº if:

ECM 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 ºincomplete,º follow the appropriate Readiness Monitor
Drive Pattern to active the monitor and change the readiness status to ºcomplete.º
CAUTION:
Strictly observe of posted speed limits, traffic laws, and road conditions when performing these
drive patterns.
NOTICE:
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 fac-
tors) the drive pattern can be resumed, and in most cases, the readiness monitor will still set to ºcom-
pleteº.
To ensure rapid completion of readiness monitors, avoid sudden changes in vehicle load and speed
(driving up and down hills and/or sudden acceleration).

START
The vehicle should be in the following conditions:

Ignition switch ON
Hand-held tester operation:
1. Select ºL/C 100º from the menu.
2. Select ºTDSº (Theft Deterrent System).
3. Select ºWIRELESS REGISTRATIONº.
After the above operations, proceed to the succeeding operations
according to the prompts on the tester screen.
Transmitter SW Operation:
