READ DATA LIST

HINT:
Using the intelligent tester'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 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 ignition switch OFF.

  3. Connect the intelligent tester to the DLC3.

  4. Turn the ignition switch ON.

  5. Turn the intelligent tester ON.

  6. Enter the following menus: Powertrain / ECT / Data List.

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

PERFORM ACTIVE TEST

HINT:
Performing the intelligent tester'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.

  1. Connect the intelligent tester to the DLC3.

  2. Turn the ignition switch ON.

  3. Turn the intelligent tester ON.

  4. Enter the following menus: Powertrain / ECT / Active Test.

  5. Perform the Active Test.

    Item
    		Test Details
    		Diagnostic Note
    Control the Shift Position
    		[Test Details]
    Operate the shift solenoid valve and set each shift lever position by yourself
    [Vehicle Condition]
    50 km/h (30 mph) or less
    [Other information]
    1. Press "→" button: Shift up
    2. Press "←" button: Shift down
    		Possible to check operation of shift solenoid valves
    Control the Lock Up
    		[Test Details]
    Control the shift solenoid SL to set the automatic transmission to the lock-up condition
    [Vehicle Condition]
    Vehicle speed: 60 km/h (37 mph) or more
    		Possible to check shift solenoid SL 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:
    OFF: Line pressure up (when Active Test of "LINE PRESS UP" is performed, ECM commands SLT solenoid to turn OFF)
    ON: No action (normal operation)

    		-

    HINT:
    *: "Control the Line Pressure Up" 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 (Click here) as well. Please note that the pressure values in the Active Test and Hydraulic Test are different.
