Electronic Controlled Automatic Transmission System -- Data List / Active Test



DATA LIST
HINT:
Using the intelligent tester 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 shorten labor 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.

  1. Warm up the engine.

  2. Turn the engine switch off.

  3. Connect the intelligent tester to the DLC3.

  4. Turn the engine switch on (IG) position.

  5. Turn on the tester.

  6. Select the item "Enter / Power train / ECT / Data List".

  7. Follow the instructions on the tester and read the Data List.

ACTIVE TEST
HINT:
Performing the intelligent tester Active Test allows relay, Vacuum Switching Valve (VSV), actuator and other items to be operated without removing any parts. Performing the Active Test early in troubleshooting is one way to shorten labor time.
The Data List can be displayed during the Active Test.

  1. Warm up the engine.

  2. Turn the engine switch off.

  3. Connect the intelligent tester to the DLC3.

  4. Turn the engine switch on (IG) position.

  5. Turn on the tester.

  6. Select the item "Enter / Power train / ECT / Active Test".

  7. Follow the instructions on the tester and read the Active Test.

    		Possible to check the SLU operation.
    Control the Line Pressure Up*
    		[Test Details]
    Operate the shift solenoid SLT and raise the line pressure.
    [Vehicle Condition]
    1. Vehicle Stopped.
    2. IDL: ON
    HINT:

    *: "Control the Line Pressure Up" in the ACTIVE TEST is performed to check the line pressure changes by connecting the SST to the automatic transmission, which is used in the HYDRAULIC TEST (Click here) as well.

    HINT:
    The pressure values in ACTIVE TEST and HYDRAULIC TEST are different from each other.
