DATA LIST/ACTIVE TEST
1. DATA LIST
HINT:
Using the hand−held tester DATA LIST allows switch, sensor, actuator and other item values to be read with-
out removing any parts. Reading DATA LIST early in troubleshooting is one way to shorten labor 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) Warm up the engine.
(b) Turn the ignition switch to OFF.
(c) Connect the hand−held tester to the DLC3.
(d) Turn the ignition switch to ON.
(e) Turn the hand−held tester ON.
(f) Enter the following menus: DIAGNOSIS / OBD/MOBD / DATA LIST.
(g) According to the display on the tester, read DATA LIST.

2. ACTIVE TEST
HINT:
Performing ACTIVE TEST using the hand−held tester allows the relay, VSV, actuator and so on to operate
without parts removal. Performing ACTIVE TEST as a first step of troubleshooting is one of the methods to
shorten diagnostic time.
It is possible to display DATA LIST during ACTIVE TEST.
(a) Turn the ignition switch to OFF.
(b) Connect the hand−held tester to the DLC3.
(c) Turn the ignition switch to ON.
(d) Turn the hand−held tester ON.
(e) Enter the following menus: DIAGNOSIS / OBD/MOBD / ACTIVE TEST.
(f) According to the display on the tester, perform ACTIVE TEST.
