AUTOMATIC TRANSAXLE SYSTEM DATA LIST / ACTIVE TEST


  1. 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 engine switch off.

    3. Connect the intelligent tester to the DLC3.

    4. Turn the engine switch on (IG).

    5. Turn the intelligent tester on.

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

  2. 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 engine switch off.

    3. Connect the intelligent tester to the DLC3.

    4. Turn the engine switch on (IG).

    5. Turn the intelligent tester on.

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

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

      [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 TCM commands the shift solenoid SLT 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 operation of the shift solenoid SLU and SL..

      [Vehicle Condition]


      • Vehicle speed: 60 km/h (37 mph) or more
      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 (30 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

      *: 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 Click here.

      Tech Tips

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