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 M208 and IPDM E/R connector E119.
   3. Check voltage between push-button ignition switch connector M17 terminal 8 and ground.

      Push-Button Ignition Switch		Ground	Voltage (Approx.)
      Connector	Terminal
      M208	8	-	Battery voltage

   Is the inspection result normal?

   YES 

   GO TO STEP 3  .

   NO 

   GO TO STEP 2  .

2. CHECK PUSH-BUTTON IGNITION SWITCH CIRCUIT (BCM)
   
   
   1. Disconnect BCM connector M18.
   2. Check continuity between BCM connector M18 terminal 1 and push-button ignition switch connector M208 terminal 8.

      BCM		Push-Button Ignition Switch		Continuity
      Connector	Terminal	Connector	Terminal
      M18	1	M208	8	Yes

   3. Check continuity between BCM connector M18 terminal 1 and ground.

      BCM		Ground	Continuity
      Connector	Terminal
      M18	1	-	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 E119 terminal 38 and ground.

   IPDM E/R		Ground	Voltage (Approx.)
   Connector	Terminal
   E119	38	-	Battery voltage

   Is the inspection result normal?

   YES 

   GO TO STEP 5  .

   NO 

   GO TO STEP 4  .

4. CHECK PUSH-BUTTON IGNITION SWITCH CIRCUIT (IPDM E/R)
   
   
   1. Disconnect BCM connector M18.
   2. Check continuity between IPDM E/R connector E119 terminal 38 and push-button ignition switch connector M208 terminal 8.

      IPDM E/R		Push-Button Ignition Switch		Continuity
      Connector	Terminal	Connector	Terminal
      E119	38	M208	8	Yes

   3. Check continuity between IPDM E/R connector E119 terminal 38 and ground.

      IPDM E/R		Ground	Continuity
      Connector	Terminal
      E119	38	-	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 M208 terminal 4 and ground.

   Push-Button Ignition Switch		Ground	Continuity
   Connector	Terminal
   M208	4	-	Yes

   Is the inspection result normal?

   YES 

   GO TO STEP 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. Refer to REMOVAL AND INSTALLATION .
