DATA LIST / ACTIVE TEST

1. DATA LIST

HINT: Reading the Data List displayed on Techstream enables values, including those of the switches, sensors, and actuators, to be checked without removing any parts. Reading the Data List as the first step in troubleshooting is one method to shorten diagnostic time.

NOTE: In the table below, the values listed under Normal Condition 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 off.
(c) Connect Techstream to the DLC3.
(d) Start the engine.
(e) Turn the tester on.
(f) Select the following menu items: Powertrain / Engine and ECT / Data List / All Data.
(g) Check the values by referring to the table below.





































*: If no idling conditions are specified, the transmission gear selector lever should be in the N or P position, and the A/C switch and all accessory switches should be OFF.
2. ACTIVE TEST

HINT: Performing an Active Test enables components including the relays, VSV (Vacuum Switching Valve), and actuators, to be operated without removing any parts. The Active Test can be performed with Techstream. Performing an Active Test in the first step in troubleshooting is one method to shorten diagnostic time.

Data List can be displayed during Active Tests.

(a) Connect Techstream to the DLC3.
(b) Start the engine.
(c) Turn the tester on.
(d) Select the following menu items: Powertrain / Engine and ECT / Active Test.
(e) Perform the Active Test by referring to the table below.









3. SYSTEM CHECK

HINT: Performing a System Check enables the system, which consists of the multiple actuators, to be operated without removing any parts. In addition, it can show whether or not any DTCs are set, and can detect potential malfunctions in the system. The SYSTEM CHECK can be performed with Techstream.

(a) Connect Techstream to the DLC3.
(b) Start the engine.
(c) Turn the tester on.
(d) Select the following menu items: Powertrain / Engine and ECT / Utility / System Check.
(e) Perform the System Check by referring to the table below.
