Diagnosis Procedure

WARNING: This page is about a different car, the 2011 Nissan Quest. However, it is still accessible from the selected car via links, so may be relevant.
  1. CHECK PUSH-BUTTON IGNITION SWITCH (PUSH SWITCH) OUTPUT SIGNAL
    1. Disconnect push-button ignition switch connector and IPDM E/R connector.
    2. Check voltage between push-button ignition switch harness connector and ground.

      (+) (-) Voltage (V) (Approx.)
      Push-button Ignition switch
      Connector Terminal
      M101 4 Ground 9 - 16

      Is the inspection result normal? 

      YES: Go to  3.

      NO: Go to 2.

  2. CHECK PUSH-BUTTON IGNITION SWITCH CIRCUIT (BCM)
    1. Disconnect BCM connector.
    2. Check continuity between BCM harness connector and push-button ignition switch harness connector.

    E10 28 Ground 9 - 16

    Is the inspection result normal? 

    YES: Replace IPDM E/R.

    NO: Go to 4.

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

      Is the inspection result normal? 

      YES: Go to 5.

      NO: Repair or replace harness.

  5. CHECK INTERMITTENT INCIDENT

    Refer to "INTERMITTENT INCIDENT ".
