DTC Diagnosis Procedure

Regarding Wiring Diagram information, refer to the appropriate 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 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 2 .

   NO

   GO TO 4 .

2. CHECK PUSH-BUTTON 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 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 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

   4. 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

   Refer to Intermittent Incident .

   NO

   Repair or replace harness or connectors.

4. CHECK IGNITION SWITCH OUTPUT SIGNAL (BCM) 

   Check voltage between BCM connector M98 terminal 76 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 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

   4. Check continuity between BCM connector M98 terminal 76 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.
