CHECKING MONITOR STATUS
NOTICE:
The monitor status (mode 6) is not applicable to the heated oxygen sensor (HO2S). However, HO2S
test values can be checked by O2S TEST RESULT (mode 5). Refer to page 05-22
1. Outline
The monitor results and the test values can be checked with the OBDII scan tool.
The engine control module (ECM) monitors the emissions-related components as the thermostat, catalyst
converter and evaporative emissions (EVAP), and determines whether they are functioning normally or not.
When finished monitoring, the ECM stores the monitor results and the test values.
The monitor result indicates whether the component is functioning normally or not. The test value is the value
that was used to determine the monitor result. If the test value is outside the test limit (malfunction criterion),
the ECM determines the component is malfunctioning. Some emissions-related components have multiple
test values to determine monitor result. If one of these test values is outside test limit, the ECM determines
the component is malfunctioning.
2. Description
The test value and test limit information are described as shown in the following table. This information is
included under ºMONITOR RESULTº in the emissions-related DTC sections:
TID $08: Thermostat
TID (Test Identification Data) is assigned to each emissions-related component.
TLT (Test Limit Type):
If TLT is 0, the component is malfunctioning when the test value is higher than the test limit.
If TLT is 1, the component is malfunctioning when the test value is lower than the test limit.
CID (Component Identification Data) is assigned to each test value.
Unit Conversion is used to calculate the test value indicated on generic OBDII scan tools.

3. Procedure (using hand-held tester)
(a) Connect the hand-held tester to the DLC3.
(b) Turn the ignition switch and hand-held tester ON.
(c) Clear DTCs.
(d) Allow the vehicle to drive, in accordance with the applicable drive pattern described in the READINESS
MONITOR DRIVE PATTERN section (see page 05-26).
(e) Select the hand-held tester menus: DIAGNOSIS, EN-
HANCED OBDII, MONITOR INFO and MONITOR RE-
SULT. The monitor result appears after the component
name.
INCMP indicates the component has not been monitored
yet.
PASS indicates the component is functioning normally.
FAIL indicates the component is malfunctioning.
(f) Select the component and press ENTER. If the monitor
result has been PASS or FAIL, the accuracy test value ap-
pears.
VAL indicates the test value.
LMT indicates the test limit (malfunction criterion).
TLT indicates the test limit type.
(g) Compare the test value with the test limit.
If TLT is 0, the component is malfunctioning when the test
value is higher than the test limit.
If TLT is 1, the component is malfunctioning when the test
value is lower than the test limit.
If the test value is on the borderline of the test limit, a mal-
function is concealed in the component.
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.

CHECK FOR INTERMITTENT PROBLEMS
Hand-held tester only:
Inspect the vehicle's ECM using check mode. Intermittent problems are easier to detect when the
ECM is in check mode with the hand-held tester. In check mode, the ECM uses 1 trip detection logic,
which has a higher sensitivity to malfunctions than normal mode (default), which uses 2 trip detec-
tion logic.
(a) Clear the DTCs (see page 05-38).
(b) Set the check mode (see page 05-40).
(c) Perform a simulation test (see page 01-26).
(d) Check the connector and terminal (see page 01-36).
(e) Wiggle the harness and the connector (see page 01-36).

CHECK MODE PROCEDURE
HINT:
Hand-held tester only:
Check mode has a higher sensitivity to malfunctions and can
detect malfunctions that normal mode cannot detect. Check
mode can also detect all the malfunctions that normal mode can
detect.
1. CHECK MODE PROCEDURE (Using the hand-held
tester)
(a) Make sure that the items below are true:
(1) Battery positive voltage 11 V or more
(2) Throttle valve fully closed
(3) Transmission in the P or N position
(4) A/C switched OFF
(b) Turn the ignition switch OFF.
(c) Connect the hand-held tester to the DLC3.
(d) Turn the ignition switch ON.
(e) Change the ECM to check mode with the hand-held tes-
ter. Enter the following menus: DIAGNOSIS / EN-
HANCED OBD II / CHECK MODE. Make sure the MIL
flashes as shown in the illustration.
NOTICE:
All DTCs and freeze frame data recorded will be erased if:
1) the hand-held tester is used to change the ECM from
normal mode to check mode or vice-versa; or 2) during
check mode, the ignition switch is turned from ON to ACC
or OFF.
(f) Start the engine. The MIL should turn off after the engine
starts.
(g) Simulate the conditions of the malfunction described by
the customer.
(h) After simulating the malfunction conditions, use the
hand-held tester diagnosis selector to check the DTC,
freeze frame data and other data.
(1) After checking the DTC, inspect the applicable cir-
cuit.
