DATA LIST / ACTIVE TEST
1. DATA LIST
Using the Techstream to read the Data List allows the values or states of switches, sensors, 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) Connect the Techstream to the DLC3.
(b) Turn the power switch on (IG).
(c) Turn the Techstream on.
(d) Enter the following menus: Body Electrical / Air Conditioner / Data List.
