AUTOMATIC TRANSAXLE SYSTEM DATA LIST / ACTIVE TEST


  1. DATA LIST

    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.

    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 air conditioning switch off.

    3. Turn the ignition switch off.

    4. Connect the GTS to the DLC3.

    5. Turn the ignition switch to ON.

    6. Turn the GTS on.

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

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

  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. Perform the Active Test according to the display on the GTS.


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

      Connects and disconnects TC and TE1.

      (For activation of 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 the solenoid (SLU) valve ON/OFF

        [Vehicle Condition]

      • Engine stopped

      • Shift lever in P or N
      Activate the Solenoid (SLT) Operates the solenoid (SLT) valve to raise the line pressure

      ON/OFF

      Tech Tips

      ON: No action (normal operation)

      OFF: Line pressure increases (When performed, the ECM commands the solenoid (SLT) valve to turn off)

        [Vehicle Condition]

      • Vehicle Stopped

      • IDL: ON
      Activate the Lock Up Operates the solenoid (SLU and SL) valves to control the automatic transaxle lock-up condition ON/OFF

      Can be used to check the operation of the solenoid (SLU and SL) valves.


        [Vehicle Condition]

      • Throttle valve opening angle: Less than 20%

      • Vehicle speed: 60 km/h (37 mph) or more in 6th gear
      Activate the Solenoid (SL) Operates the solenoid (SL) valve ON/OFF

        [Vehicle Condition]

      • Engine stopped

      • Shift lever in P or N
      Control the Shift Position Operates the 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 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 the solenoid (SL1) valve ON/OFF

        [Vehicle Condition]

      • Engine stopped

      • Shift lever in P or N
      Activate the Solenoid (SL2) Operates the solenoid (SL2) valve ON/OFF

        [Vehicle Condition]

      • Engine stopped

      • Shift lever in P or N
      Activate the Solenoid (SL3) Operates the solenoid (SL3) valve ON/OFF

        [Vehicle Condition]

      • Engine stopped

      • Shift lever in P or N
      Activate the Solenoid (SL4) Operates the solenoid (SL4) valve ON/OFF

        [Vehicle Condition]

      • Engine stopped

      • Shift lever in P or N

      Tech Tips


      • Performing the Active Test "Activate the Solenoid (SLT)" allows the change in line pressure to be checked with SST installed to the automatic transaxle. The same SST is used for the Hydraulic Test.

      • Note that the pressure readings for the Active Test and Hydraulic Test are different.
