5. CHECK FOR INTERMITTENT PROBLEMS
Hand±held tester only:
By putting the vehicle's ECM in the check mode, the 1 trip detection logic is possible instead of the 2 trip
detection logic, and the sensitivity to detect faults is increased. This makes it easier to detect intermittent
problems.
(a) Clear the DTCs (See step 2).
(b) Set the check mode (See step 3).

6. DATA LIST
HINT:
Using the DATA LIST displayed by the hand±held tester, you can read the value of the switches, sensors,
actuators and so on without parts removal. Reading the DATA LIST as a first step of troubleshooting is one
method to shorten diagnostic time.
NOTICE:
The values given below for ºNormal Conditionº are representative valu\
es. A vehicle may still be nor-
mal even if its value differs from those listed here. Do not solely depend \
on the ºNormal Conditionº
here when deciding whether a part is faulty or not.
(a) Warm up the engine.
(b) Turn the ignition switch OFF.
(c) Connect the hand±held tester to the DLC3.
(d) Turn the ignition switch ON.
(e) Push the ºONº button of the hand±held tester.
(f) Select the item ºDIAGNOSIS / OBD/MOBD / DATA LISTº.
(g) According to the display on tester, read the ºDATA LISTº.

7. ACTIVE TEST
HINT:
Performing the ACTIVE TEST using the hand±held tester allows the relay, VSV, actuator and so on to oper-
ate without parts removal. Performing the ACTIVE TEST as a first step of troubleshooting is one of the meth-
ods to shorten diagnostic time.
It is possible to display the DATA LIST during the ACTIVE TEST.
(a) Warm up the engine.
(b) Turn the ignition switch OFF.
(c) Connect the hand±held tester to the DLC3.
(d) Turn the ignition switch ON.
(e) Push the ºONº button of the hand±held tester.
(f) Select the item ºDIAGNOSIS / OBD/MOBD / ACTIVE TESTº
