DATA LIST
HINT:
By reading the Data List displayed on an intelligent tester ll, you can check values, including those of the
switches, sensors, and actuators, without removing any parts. Reading the Data List as the first step of trou-
bleshooting is one method of shortening diagnostic time.
NOTICE:
In the table below, the values listed under Normal Conditions are for reference only. Do not depend
solely on these values when determining whether or not a part is faulty.
(a)
Warm up the engine.
(b)
Turn the ignition switch to OFF.
(c)
Connect an intelligent tester II to the DLC3.
(d)
Turn the ignition switch to ON.
(e)
Turn the tester ON.
(f)
Select the following menu items: Powertrain / Engine and ECT / Data List.
(g)
Check the values by referring to the following table.
