DATA LIST / ACTIVE TEST
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:
Data List values may experience significant variations due to small differences in measurement, different measurement environments, changes in the vehicle over time, etc., making it difficult to display a clear standard value for judgment. Due to this, it is possible that malfunctions could exist even when values are within the specified ranges.
DATA LIST
(a) Connect the Techstream to the DLC3.
(b) Turn the ignition switch to ON.
(c) Turn the Techstream on.
(d) Enter the following menus: Body Electrical / Pre-Collision System / Data List.
(e) Read the Data List according to the display on the Techstream.

Performing Active Tests early in troubleshooting is one way to save diagnostic time. Data List information can be displayed while performing Active Tests.
(a) Connect the Techstream to the DLC3.
(b) Turn the ignition switch to ON.
(c) Turn the Techstream on.
(d) Enter the following menus: Body Electrical / Pre-Collision System / Active Test.
