AUTOMATIC TRANSAXLE SYSTEM DATA LIST / ACTIVE TEST


  1. DATA LIST

    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.

    Tech Tips

    Using the GTS 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.


    1. Warm up the engine.

    2. Turn the ignition switch off.

    3. Connect the GTS to the DLC3.

    4. Turn the ignition switch to ON.

    5. Turn the GTS on.

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

      Tech Tips


      • To display the list box, press the pull down menu button next to Primary. Then select a measurement group.

      • When you select a measurement group, the ECU data belonging to that group is displayed.

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

      Tech Tips


      • The title used for each group of Data List items in this repair manual does not appear on the GTS. However, the name in parentheses after the title, which is a Measurement Group, does appear on the GTS. When the name shown in parentheses is selected on the GTS, all the Data List items listed for that group will be displayed.

      • "Result of real-vehicle check" is the assessment of one vehicle. Use it only for reference.

      This is the engine coolant temperature.

      Tech Tips


      • After warming up the engine, the engine coolant temperature is 75 to 100°C (167 to 212°F).

      • After a long soak, the engine coolant temperature, intake air temperature and ambient air temperature are approximately equal.

      • If the value is -40°C (-40°F), or 140°C (284°F), the sensor circuit is open or shorted.

      • Check if the engine overheats when the value indicates 140°C (284°F).

  2. ACTIVE TEST

    Tech Tips

    Using the GTS 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 GTS to the DLC3.

    4. Turn the ignition switch to ON.

    5. Turn the GTS on.

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

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


      Powertrain > Engine > Active Test
      Tester Display Measurement Item Control Range Diagnostic Note
      Connect the TC and TE1

      Connects and disconnects TC and TE1.

      (changes to the fluid temperature detection mode)

      ON/OFF The MIL will not blink when "Connect the TC and TE1 / ON" is selected.
      Activate the Solenoid (SLU) Operates shift solenoid SLU ON/OFF

      [Vehicle Condition]


      • Engine stopped

      • Shift lever in P or N

      Activate the Solenoid (SLT) Operates shift solenoid SLT to raise the line pressure.

      ON/OFF

      Tech Tips

      ON: No action (normal operation)

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

      [Vehicle Condition]


      • Vehicle Stopped

      • IDL: ON

      Activate the Lock Up Controls the shift solenoid SLU and SL to set the automatic transaxle to the lock-up condition. ON/OFF

      Can be used to check SLU and SL solenoid operation.

      [Vehicle Condition]


      • Throttle valve opening angle: Less than 20%

      • Vehicle speed:60 km/h (37 mph) or more, and 6th gear

      Activate the Solenoid (SL) Operates shift solenoid SL ON/OFF

      [Vehicle Condition]


      • Engine stopped

      • Shift lever in P or N

      Control the Shift Position Operates the shift solenoid valves to allow gears to be selected manually.
      • Press "→" button: Upshift occurs

      • Press "←" button: Downshift occurs

      Can be used to check the operation of the shift solenoid valves.

      Upshifts and downshifts should be performed consecutively. A 10-second interval is required between gear changes.

      Do not downshift at high speeds. Doing so will damage the automatic transaxle.

      [Vehicle Condition]


      • 50 km/h (31 mph) or less

      Activate the Solenoid (SL1) Operates shift solenoid SL1 ON/OFF

      [Vehicle Condition]


      • Engine stopped

      • Shift lever in P or N

      Activate the Solenoid (SL2) Operates shift solenoid SL2 ON/OFF

      [Vehicle Condition]


      • Engine stopped

      • Shift lever in P or N

      Activate the Solenoid (SL3) Operates shift solenoid SL3 ON/OFF

      [Vehicle Condition]


      • Engine stopped

      • Shift lever in P or N

      Activate the Solenoid (SL4) Operates shift solenoid SL4 ON/OFF

      [Vehicle Condition]


      • Engine stopped

      • Shift lever in P or N

      Tech Tips


      • The "Activate the solenoid (SLT)" Active Test is performed to allow confirmation that the line pressure changes. The line pressure changes are confirmed using the same SST that is used for the Hydraulic Test.
