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.
