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).

±
DIAGNOSTICS ECD SYSTEM(1CD±FTV)
05±533
AVENSIS REPAIR MANUAL (RM1018E)
(c)Perform a simulation test (See page 01±22).
(d)Check the connector and terminal (See page 01±32).
(e)Wiggle the harness and 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
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.
