2ZR-FXE ENGINE CONTROL: SFI SYSTEM: DATA LIST / ACTIVE TEST

1. DATA LIST

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.

(a) Warm up the engine.

(b) Turn the A/C switch off.

(c) Turn the power switch off.

(d) Connect the Techstream to the DLC3.

(e) Turn the power switch on (IG).

(f) Turn the Techstream on.

(g) Enter the following menus: Powertrain / Engine and ECT / Data List.

HINT

(h) According to the display on the Techstream, read the Data List.

HINT
The title used for each group of Data List items in this repair manual does not appear on the Techstream. However, the name in parentheses after the title, which is a Measurement Group, does appear on the Techstream. When the name shown in parentheses is selected on the Techstream, all the Data List items listed for that group will be displayed.
