    1. Disconnect the ECM connector.
    2. Remove the ST relay from the engine room relay block assembly.
    3. Measure the resistance according to the value(s) in the table below.

      Standard Resistance (Check for open)

      Tester Connection Condition Specified Condition
      A35-26 (STA) - ST relay terminal 1 Always Below 1 Ω
      A33-17 (STSW2) - ST relay terminal 3 Always Below 1 Ω

      Standard Resistance (Check for short)

      Tester Connection Condition Specified Condition
      A35-26 (STA), A33-17 (STSW2), ST relay terminal 1 or ST relay terminal 3 - Body ground Always 10 kΩ or higher

    Result: 

    OK 

    PROCEED TO NEXT SUSPECTED AREA SHOWN IN PROBLEM SYMPTOMS TABLE 

    (Refer to PROBLEM SYMPTOMS TABLE [03/2017 - ] )

    Result: 

    NG 

    REPAIR OR REPLACE HARNESS OR CONNECTOR 

  34. READ VALUE USING TECHSTREAM (STARTER SIGNAL) 
    1. Connect the Techstream to DLC3.
    2. Turn the ignition switch to ON.
    3. Turn the Techstream on.
    4. Enter the following menus: Powertrain / Engine / Data List / Starter Signal.
    5. Check the value displayed on the Techstream when the ignition switch is turned to the ON and START positions.
      OK

      Ignition Switch Position Starter Signal
      ON Close (OFF)
      START Open (ON)
