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 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.
