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 Techstream 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 Techstream to the DLC3.

    4. Turn the ignition switch to ON.

    5. Turn the Techstream 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.

      • Measurement Group List / Description

    7. According to the display on the Techstream, 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 Techstream. However, the name in parentheses after the title, which is a Measurement Group, does appear on the Techstream. When the name shown in parentheses is selected on the Techstream, 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.

      Engine Speed

      Engine speed /

      Min.: 0 rpm, Max.: 16383.75 rpm

      600 to 700 rpm: Idling When the crankshaft position sensor is malfunctioning, "Engine Speed" is approximately 0 rpm or varies greatly from the actual engine speed.
      Calculate Load

      Calculated load /

      Min.: 0.0%, Max.: 100.0%


      • Ignition switch ON: 0.0%

      • Idling (engine warmed up): 28.2%

      • Running without load (3000 rpm): 26.2%

      • Vehicle driven at constant speed of 60 km/h (37 mph): 56.8%

      This is the engine load calculated based on the estimated intake manifold pressure.

      Calculate Load = Estimated intake manifold pressure / maximum intake manifold pressure x 100 (%)

      (For example, when the estimated intake manifold pressure is the same as atmospheric pressure, Calculate Load is 100%.)

      This is the throttle valve opening amount used for engine control.

      (100% signifies 125° of throttle valve rotation. This does not include the amount the throttle valve is opened to maintain the idle speed during idling.)

      This value has no meaning when the ignition switch is ON and the engine is stopped.

      The throttle valve opening amount during idling is indicated by 0%. When the throttle valve is fully open, the value is 68%.

  2. ACTIVE TEST

    Tech Tips

    Using the Techstream 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 Techstream to the DLC3.

    4. Turn the ignition switch to ON.

    5. Turn the Techstream on.

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

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

      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 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

      Control the Shift Position Operates the shift solenoid valves to allow gears to 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

      *: 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.
