PROCEDURE


  1. READ VALUE USING GTS (ENGINE SPEED AND SPD (NIM))


    1. Connect the GTS to the DLC3.

    2. Turn the ignition switch to ON.

    3. Turn the GTS on.

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

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


      Powertrain > Engine and ECT > Data List
      Tester Display Measurement Item Range Normal Condition Diagnostic Note
      Engine Speed Engine speed

      Min.: 0 rpm

      Max.: 16383 rpm

      		 710 to 810 rpm: Idling When the crankshaft position sensor is malfunctioning, "Engine Speed" is approximately 0 rpm or varies greatly from the actual engine speed.
      SPD (NIM) Input shaft speed (NIM)

      Min.: 0 rpm

      Max.: 16383 rpm

      		 Input shaft speed (NIM) equal to engine speed (NE): Clutch pedal not depressed, vehicle running -
