Scan Tool Testing and Procedures
DATA LIST / ACTIVE TEST1. READ DATA LIST
HINT: Using the intelligent tester or 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 ignition switch OFF.
(c) Connect the intelligent tester or Techstream to the DLC3.
(d) Turn the ignition switch ON and push the tester switch ON.
(e) Enter the following menus:
(1) Intelligent tester - Select: DIAGNOSIS / OBD/MOBD / ECT / DATA LIST.
(2) Techstream - Select: Powertrain / Engine and ECT / Data List.
(f) Follow the instructions on the tester and read the Data List.

2. PERFORM ACTIVE TEST
HINT: Using the intelligent tester or Techstream to perform Active Tests allows relays, VSVs, actuators and other items to be operated without removing any parts. This non-intrusive functional inspection can be very useful because intermittent operation may be discovered before parts or wiring is disturbed. Performing Active Tests early in troubleshooting is one way to save diagnostic time. Data List information can be displayed while performing Active Tests.
(a) Warm up the engine.
(b) Turn the ignition switch OFF.
(c) Connect the intelligent tester or Techstream to the DLC3.
(d) Turn the ignition switch ON and push the tester switch ON.
(e) Enter the following menus:
(1) Intelligent tester - Select: DIAGNOSIS / OBD/MOBD / ECT / ACTIVE TEST.
(2) Techstream - Select: Powertrain / Engine and ECT / Active Test.
(f) Follow the instructions on the tester and perform the Active Test.
(1) Intelligent tester
ECT:
HINT: *: SOLENOID(SLT) in the Active Test is performed to check the line pressure changes by connecting SST to the automatic transmission, which is used in the HYDRAULIC TEST as well. Please note that the pressure values in the Active Test and HYDRAULIC TEST are different.
(2) Techstream
ECT:
HINT: *: Active the Solenoid (SLT) in the Active Test is performed to check the line pressure changes by connecting SST to the automatic transmission, which is used in the HYDRAULIC TEST as well. Please note that the pressure values in the Active Test and HYDRAULIC TEST are different.
