AUTOMATIC TRANSAXLE SYSTEM (for 3ZR-FE) DATA LIST / ACTIVE TEST


  1. READ DATA LIST

    Tech Tips

    Using the intelligent tester 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.

    Note

    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 to ON.

    5. Turn the intelligent tester on.

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

    7. According to the display on the tester, read the Data List.

  2. PERFORM ACTIVE TEST

    Tech Tips

    Using the intelligent tester 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.


    1. Warm up the engine.

    2. Turn the ignition switch off.

    3. Connect the intelligent tester to the DLC3.

    4. Turn the ignition switch to ON.

    5. Turn the intelligent tester on.

    6. Enter the following menus: Powertrain / Engine and ECT / Active Test.

    7. According to the display on the tester, perform the Active Test.

      Engine and ECT
      Tester Display Test Part Control Range Diagnostic Note
      Activate the Solenoid (SLT)* Operate shift solenoid valve SLT and raise line pressure

      ON or OFF

      Tech Tips

      OFF: Line pressure up (when Active Test "Activate the Solenoid (SLT)" is performed, ECM commands SLT solenoid to turn OFF)

      ON: No action (normal operation)

      [Vehicle Condition]


      • The vehicle is stopped.

      • The engine is idling.

      Activate the Solenoid (S4) Operate shift solenoid valve S4 ON or OFF

      [Vehicle Condition]


      • The engine is stopped.

      • The shift lever is in P or N.

      Activate the Lock Up Control shift solenoid valve DSL to set automatic transaxle to lock-up condition ON or OFF

      It is possible to check the shift solenoid valve DSL operation.

      [Vehicle Condition]


      • The throttle valve opening amount is less than 35%.

      • The vehicle speed is 60 km/h (37 mph) or more.

      Control the Shift Position Operate shift solenoid valve and set each shift position
      • Press "→" button: Shift up

      • Press "←" button: Shift down

      It is possible to check the operation of the shift solenoid valves.

      [Vehicle Condition]

      The vehicle speed is 50 km/h (31 mph) or less.

      Activate the Solenoid (DSL) Operate shift solenoid valve DSL ON or OFF

      [Vehicle Condition]


      • The engine is stopped.

      • The shift lever is in P or N.

      Activate the Solenoid (SL1) Operate shift solenoid valve SL1 ON or OFF

      [Vehicle Condition]


      • The engine is stopped.

      • The shift lever is in P or N.

      Activate the Solenoid (SL2) Operate shift solenoid valve SL2 ON or OFF

      [Vehicle Condition]

      Tech Tips

      *: "Activate the Solenoid (SLT)" in the Active Test is performed to check the line pressure changes by connecting SST to the automatic transaxle, which is used in the Hydraulic Test Click here as well. Note that the pressure values in the Active Test and Hydraulic Test are different.
