Data List / Active Test [06/2018 - 08/2020]

  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.

    HINT: 

    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 engine switch off.
    3. Connect the Techstream to the DLC3.
    4. Turn the engine switch on (IG).
    5. Turn the Techstream on.
    6. Enter the following menus: Powertrain / Transmission / Data List.
    7. Read the Data List according to the display on the Techstream.

      Total Distance Traveled Total distance traveled Min.: 0
      Max.: 16777215
      - -
      Total Distance Traveled - Unit Unit for Total Distance Traveled km or mile - -
      Vehicle Speed Vehicle speed Min.: 0 km/h (0 mph)
      Max.: 255 km/h (158 mph)
      Actual vehicle speed
      • This is the current vehicle speed.
      • The vehicle speed is detected using the wheel speed sensors.
        • Vehicle speed data is delayed when it is displayed. Therefore, even if the vehicle speed listed in the freeze frame data is 0 km/h (0 mph), this does not always mean that the malfunction occurred when the vehicle was stopped.
      Engine Speed Engine Speed Min.: 0 rpm
      Max.: 16383 rpm
      600 to 700 rpm: Engine idling (shift lever in N, engine warmed up and A/C off) When the crankshaft position sensor is malfunctioning, "Engine Speed" is approximately 0 rpm or varies greatly from the actual engine speed.
      Calculate Load Load calculated by ECM Min.: 0%
      Max.: 100%
      -
      • This is the engine load calculated based on the estimated intake manifold pressure.
      • Calculate Load = Actual intake manifold pressure / maximum intake manifold pressure x 100 (%)

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

      Coolant Temperature Engine coolant temperature Min.: -40°C (-40°F)
      Max.: 140°C (284°F)
      75 to 100°C (167 to 212°F): After warming up HINT: 
      • 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 higher than 135°C (275°F), the sensor circuit is open or shorted.
      • Check if the engine overheats when the value indicates higher than 135°C (275°F).
      Intake Air Temperature Intake air temperature Min.: -40°C (-40°F)
      Max.: 140°C (284°F)
      Equivalent to temperature at location of mass air flow meter sub-assembly HINT: 
      • After a long soak, the engine coolant temperature, intake air temperature and ambient air temperature will be approximately equal.
      • If the value is -40°C (-40°F), or higher than 128°C (262°F), the sensor circuit is open or shorted.
      Ambient Temperature Ambient temperature Min.: -40°C (-40°F)
      Max.: 215°C (419°F)
      Equivalent to ambient temperature HINT: 
      After a long soak, the engine coolant temperature, intake air temperature and ambient air temperature will be approximately equal.

      Time after engine start -
      Battery Voltage Battery voltage Min.: 0
      Max.: 65.5 V
      11 to 14 V: Engine switch on (IG) If 11 V or less, characteristics of some electrical components may change.
      BATT Voltage Battery voltage Min.: 0

      Throttle Position Sensor No. 1 Voltage % Absolute No. 1 throttle position sensor Min.: 0%
      Max.: 100%
      • 10 to 22%: Accelerator pedal fully released
      • 64 to 96%: Accelerator pedal fully depressed (engine running)
      The No. 1 throttle position sensor output is converted using 5 V = 100%.
      HINT: 
      If there are no throttle position sensor DTCs stored, it is possible to conclude that the throttle position sensor system is normal.

      • ON: Shift lever in P or N
      • OFF: Shift lever not in P or N
      When the shift lever position displayed on the Techstream differs from the actual position, the adjustment of the park/neutral position switch assembly or shift cable may be incorrect.
      HINT: 
      If a malfunction still occurs even after adjusting these parts, refer to DTC P0705-13 or P0705-62*3.

  2. ACTIVE TEST 

    HINT: 

    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 engine switch off.
    3. Connect the Techstream to the DLC3.

      HINT: 

      • 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.

        Refer to HYDRAULIC TEST [06/2018 - ] 

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