DATA LIST / ACTIVE TEST
1. DATA LIST
HINT:
Using the intelligent tester to read the DATA LIST allows
the values or states of switches, sensor, actuators and
other items to be read without removing any parts. This
non-intrusive inspection can be very useful because
intermittent conditions or signals may be discovered
before parts or wiring is disturbed. Reading the DATA
LIST information early in troubleshooting is one way to
save diagnostic time.
NOTICE:
In the table below, the values listed under "Normal
Condition" are reference values. Do not depend
solely on these reference values when deciding
whether a part is faulty or not.
(a) Make sure that the ignition switch is off.
(b) Connect the intelligent tester to DLC3.
(c) Turn the ignition switch to the ON position.
(d) Following the display on the intelligent tester, read
"DATA LIST".

HINT:
*1: Displayed only when the ID No. is not registered.
*2: It may take about 5 to 6 minutes until the values
are displayed. If the values are not displayed after a
few minutes, perform troubleshooting according to
the inspection procedure for DTCs C2121/21 to
C2124/24 (See page TW-42).

2. ACTIVE TEST
Using the intelligent tester to perform ACTIVE TEST
allows the meters, indicators and other items to be
operated without removing any parts. Performing
ACTIVE TEST early in troubleshooting is one way to
save diagnostic time. It is possible to display the DATA
LIST on the intelligent tester during ACTIVE TEST.
(a) Make sure that the ignition switch is off.
(b) Connect the intelligent tester to the DLC3.
(c) Turn the ignition switch to the ON position.
