Diagnosis Procedure

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

1. CHECK PUSH-BUTTON IGNITION SWITCH OUTPUT SIGNAL (PUSH-BUTTON IGNITION SWITCH) 
   1. Disconnect push-button ignition switch connector.
   2. Check voltage between push-button ignition switch connector M25 and ground.

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

      Is the inspection result normal? 

      YES: GO TO 2.

      NO: GO TO  4.

2. CHECK PUSH-BUTTON IGNITION SWITCH OUTPUT SIGNAL (IPDM E/R) 

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

   IPDM E/R		Ground	Voltage (Approx.)
   Connector	Terminal
   E47	81	-	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. Turn ignition switch OFF.
   2. Disconnect IPDM E/R connector E47 and BCM connector M98.
   3. Check continuity between IPDM E/R connector E47 and push-button ignition switch connector M25.

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

   4. Check continuity between IPDM E/R connector E47 and ground.

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

      Is the inspection result normal? 

      YES: Refer to "INTERMITTENT INCIDENT ".

      NO: Repair or replace harness or connectors.

4. CHECK IGNITION SWITCH OUTPUT SIGNAL (BCM) 

   Check voltage between BCM connector M98 and ground.

   BCM		Ground	Voltage (Approx.)
   Connector	Terminal
   M98	76	-	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. Turn ignition switch OFF.
   2. Disconnect BCM connector M98 and IPDM E/R connector E47.
   3. Check continuity between BCM connector M98 and push-button ignition switch connector M25.

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

   4. Check continuity between BCM connector M98 and ground.

      BCM		Ground	Continuity
      Connector	Terminal
      M98	76	-	No

      Is the inspection result normal? 

      YES: Refer to "INTERMITTENT INCIDENT ".

      NO: Repair or replace harness or connectors.
