Diagnosis Procedure

Regarding Wiring Diagram information, refer to "WIRING DIAGRAM ".

1. CHECK PUSH-BUTTON IGNITION SWITCH OUTPUT SIGNAL (PUSH-BUTTON IGNITION SWITCH) 
   1. Turn ignition switch OFF.
   2. Disconnect push-button ignition switch connector and IPDM E/R connector E47.
   3. Check voltage between push-button ignition switch connector M25 terminal 8 and ground.

      Push-button ignition switch		Ground	Voltage (Approx.)
      Connector	Terminal
      M25	8	-	Battery voltage

      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 M98.
   2. Check continuity between BCM connector M98 terminal 76 and push-button ignition switch connector M25 terminal 8.

      BCM		Push-button ignition switch		Continuity
      Connector	Terminal	Connector	Terminal
      M98	76	M25	8	Yes

   3. Check continuity between BCM connector M98 terminal 76 and ground.

      BCM		Ground	Continuity
      Connector	Terminal
      M98	76	-	No

      Is the inspection result normal? 

      YES: Replace BCM. Refer to "REMOVAL AND INSTALLATION ".

      NO: Repair or replace harness or connectors.

3. CHECK IGNITION SWITCH OUTPUT SIGNAL (IPDM E/R) 

   Check voltage between IPDM E/R connector E47 terminal 81 and ground.

   IPDM E/R		Ground	Voltage (Approx.)
   Connector	Terminal
   E47	81	-	Battery voltage

   Is the inspection result normal? 

   YES: GO TO  5.

   NO: GO TO 4.

4. CHECK PUSH-BUTTON IGNITION SWITCH CIRCUIT (IPDM E/R) 
   1. Disconnect BCM connector M17.
   2. Check continuity between IPDM E/R connector E47 terminal 81 and push-button ignition switch connector M25 terminal 8.

      IPDM E/R		Push-button ignition switch		Continuity
      Connector	Terminal	Connector	Terminal
      E47	81	M25	8	Yes

   3. Check continuity between IPDM E/R connector E47 terminal 81 and ground.

      IPDM E/R		Ground	Continuity
      Connector	Terminal
      E47	81	-	No

      Is the inspection result normal? 

      YES: Replace IPDM E/R. Refer to "REMOVAL AND INSTALLATION ".

      NO: Repair or replace harness or connectors.

5. CHECK PUSH-BUTTON IGNITION SWITCH GROUND CIRCUIT 

   Check continuity between push-button ignition switch connector M25 terminal 4 and ground.

   Push-button ignition switch		Ground	Continuity
   Connector	Terminal
   M25	4	-	Yes

   Is the inspection result normal? 

   YES: GO TO 6.

   NO: Repair or replace harness or connectors.

6. CHECK PUSH-BUTTON IGNITION SWITCH 

   Refer to "COMPONENT INSPECTION ".

   Is the inspection result normal? 

   YES: Refer to "INTERMITTENT INCIDENT ".

   NO: Replace push-button ignition switch.
