Starter Signal Circuit: Procedure

  1. CHECK WHETHER ENGINE CAN BE CRANKED 
    1. Check if the engine can be cranked.

      Result

      Result Proceed to
      Engine cannot be cranked A
      Engine can be cranked B

    B → See step   10 

    A: Go to next step

      Standard Resistance

      Tester Connection Condition Specified Condition
      1 (ST relay) - Body ground Always Below 1 Ω

    NG → REPAIR OR REPLACE HARNESS OR CONNECTOR 

    OK: Go to next step 

  8. CHECK HARNESS AND CONNECTOR (PARK/NEUTRAL POSITION SWITCH ASSEMBLY - CERTIFICATION ECU (SMART KEY ECU ASSEMBLY) - ST RELAY) 
    1. Remove the ST relay from the engine room relay block and junction block assembly.
    2. Disconnect the park/neutral position switch assembly connector.
    3. Disconnect the certification ECU (smart key ECU assembly) connector.
    4. Measure the resistance according to the value(s) in the table below.
