CHECKING MONITOR STATUS
evaporative emissions (EVAP) systems.
The monitor result allows the OBD II scan tool to display the monitor status, test value, minimum test limit
and maximum test limit. These data are displayed after the vehicle has been driven to run the monitor.
When the test value is not between the minimum and maximum test limits, the ECM (PCM) interprets this as a
Perform the following procedures to view the monitor status. Although these procedures refer to the
Lexus/Toyota Techstream, the monitor status can be checked using a generic OBD II scan tool. Refer to your
scan tool operator's manual for specific procedural information.
1. PERFORM MONITOR DRIVE PATTERN
(a) Connect the Techstream to the DLC3.
(b) Turn the ignition switch to ON.
(c) Turn the Techstream on.
(d) Clear the DTCs
.
(e) Operate the vehicle in accordance with the applicable drive pattern described in Readiness Monitor
Drive Pattern
. Do not turn the ignition switch off.
HINT:
The test results will be lost if the ignition switch is turned off.
2. ACCESS MONITOR RESULT
(a) Enter the following menus: Powertrain / Engine and ECT / Monitor / Current Monitor / Result.
(b) Confirm the monitor status for each component.
HINT:
The monitor status for each component is displayed in the Result column.
PASS: The component is functioning normally.
FAIL: The component is malfunctioning.
(c) Display the test results and test values for a monitor by selecting the icon in the Details column for that
monitor.
(d) Display the test value for an item listed under Test Results by selecting the icon in the Details column
for that item.
3. CHECK COMPONENT STATUS
(a) Compare the test value with the minimum test limit (MIN LIMIT) and maximum test limit (MAX LIMIT).
(b) If the test value is between the minimum and maximum test limits, the component is functioning
normally. If not, the component is malfunctioning. The test value is usually not near the test limits. If

HINT:
The monitor result might on rare occasions be Pass even if the Malfunction Indicator Lamp (MIL) is
illuminated. This indicates the system malfunctioned on a previous driving cycle. This might be caused
by an intermittent problem.
4. MONITOR RESULT INFORMATION
If you use a generic scan tool, multiply the test value by the scaling value listed below.
