Diagnosis Procedure

  1. CHECK PUSH-BUTTON IGNITION SWITCH OPERATION

    Press push-button ignition switch and check if it turns to ON.

    Does ignition switch turn to ON? 

    YES: GO TO 2.

    NO: GO TO  4.

  2. CHECK IGNITION SWITCH OUTPUT SIGNAL (IPDM E/R)
    1. Disconnect push-button ignition switch harness connector.
    2. Check voltage between IPDM E/R harness connector and ground.
      TERMINALS VOLTAGE REFERENCE

      IPDM E/R Ground Voltage (V)
      Connector Terminal
      E5 28 Ground Battery voltage

    Is the inspection result normal? 

    YES: GO TO 3.

    NO: Replace IPDM E/R. Refer to "REMOVAL AND INSTALLATION ".

  3. CHECK PUSH-BUTTON IGNITION SWITCH CIRCUIT (IPDM E/R)
    1. Disconnect IPDM E/R harness connector E5 and BCM harness connector M122.
    2. Check continuity between IPDM E/R harness connector and push-button ignition switch harness connector.
      TERMINALS CONTINUITY REFERENCE

    Is the inspection result normal? 

    YES: GO TO  6.

    NO: Repair harness or connector.

  4. CHECK IGNITION SWITCH OUTPUT SIGNAL (BCM)
    1. Disconnect push-button ignition switch harness connector.
    2. Check voltage between BCM harness connector and ground.
      TERMINALS VOLTAGE REFERENCE

      BCM Ground Voltage (V)
      Connector Terminal
      M122 89 Ground Battery voltage

    Is the inspection result normal? 

    YES: GO TO 5.

    NO: Replace BCM. Refer to "REMOVAL AND INSTALLATION ".

  5. CHECK PUSH-BUTTON IGNITION SWITCH CIRCUIT (BCM)
    1. Disconnect BCM harness connector and IPDM E/R harness connector.
    2. Check continuity between BCM harness connector and push-button ignition switch harness connector.
      TERMINALS CONTINUITY REFERENCE

      BCM Push-button ignition switch Continuity
      Connector Terminal Connector Terminal
      M122 89 M50 4 Existed
    3. Check continuity between BCM harness connector and ground.
      TERMINALS CONTINUITY REFERENCE

      Connector Terminal
      M122 89 Ground Not existed

    Is the inspection result normal? 

    YES: GO TO 6.

    NO: Repair harness or connector.

  6. CHECK INTERMITTENT INCIDENT

    Refer to "INTERMITTENT INCIDENT ".
