5.CHECK FOR INTERMITTENT PROBLEMS
Hand±held tester only:
By putting the vehicle's engine ECM in check (test) mode, 1 trip detection logic is possible instead of 2 trip
detection logic, and sensitivity to detect faults is increased. This makes it eas\
ier to detect intermittent prob-
lems.
(a)Clear the DTC. (See step 3.)
(b)Set the check (test) mode. (See step 3.)
(c)Perform a simulation test. (See page 01±32)
(d)Check the connector and terminal. (See page 01±32)
(e)Wiggle the harness and the connector. (See page 01±32)
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
of the 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 the measured values are a little different from those listed here. Do\
not decide whether
a part is faulty or not solely according to the ºNormal Conditionº\
here.
(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 LIST / ALLº.
(g) According to the display on tester, read the ºDATA LISTº.

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-
od to shorten labor 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.

INSPECTION PROCEDURE
HINT:

Read freeze frame data using \f  \b \f\f
 Freeze frame data records the engine conditions
when a malfunction is detected. When troubleshooting, it is useful for d\
etermining whether the vehicle
was running or stopped, the engine was warmed up or not, the air±fuel ra\
tio was lean or rich, etc. at
the time of the malfunction.

If different DTCs that are related to a different system are output simultaneously while terminal E2 is
used as a ground terminal, terminal E2 may be open.
