Scan Tool Testing and Procedures
DATA LIST / ACTIVE TEST1. READ DATA LIST
HINT: Using the intelligent tester or Techstream's DATA LIST allows switch, sensor, actuator, and other item values to be read without removing any parts. Reading the DATA LIST early in troubleshooting is one way to save time.
NOTICE: In the table, 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 engine switch off.
(c) Connect the intelligent tester or Techstream to the DLC3.
(d) Turn the engine switch on (IG).
(e) Turn the tester ON.
(f) Enter the following menus:
Intelligent tester
Select: DIAGNOSIS / OBD/MOBD / ECT / DATA LIST.
Techstream
Select: Powertrain / ECT / Data List.
(g) Follow the instructions on the tester and read the DATA LIST.

2. PERFORM ACTIVE TEST
HINT:
Performing the intelligent tester or Techstream's ACTIVE TEST allows relay, VSV, actuator and other items to be operated without removing any parts. Performing the ACTIVE TEST early in troubleshooting is one way to save time.
The DATA LIST can be displayed during the ACTIVE TEST.
(a) Warm up the engine.
(b) Turn the engine switch off.
(c) Connect the intelligent tester or Techstream to the DLC3.
(d) Turn the engine switch on (IG).
(e) Turn the tester ON.
(f) Enter the following menus:
Intelligent tester
Select: DIAGNOSIS / OBD/MOBD / ECT / ACTIVE TEST.
Techstream
Select: Powertrain / ECT / Active Test.
(g) Perform the ACTIVE TEST.
(1) Intelligent tester
TCM:
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. Hydraulic Test
Please note that the pressure values in the ACTIVE TEST and HYDRAULIC TEST are different.
(2) Techstream
TCM:
HINT:
*:"Activate 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. Hydraulic Test
Please note that the pressure values in the Active Test and HYDRAULIC TEST are different.
