(h) Details of relevant Data List items (Selected system: EMPS)
HINT
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.
(1) Turn the power switch off.
(2) Connect the Techstream to the DLC3.
(3) Turn the power switch on (IG).
(4) Turn the Techstream on.
(5) Enter the following menus: Chassis / EMPS / Data List.
(6) According to the display on the Techstream, read the Data List.

(k) Details of relevant Data List items (Selected system: Transmission Control)
NOTICE:
* Some Data List values may vary significantly if there are slight differences in the environment in which the vehicle is operating when measurements are obtained. Variations may also occur due to aging of the vehicle. Due to these considerations, it is not always possible to provide definite values to be used for judgment of malfunctions. It is possible that a malfunction may be present even if measured values are within the reference range.
* In the event of a problem with intricate symptoms, collect sample data from another vehicle of the same model operating under identical conditions in order to reach an overall judgment by comparing all the items in the Data List.
