Diagnosis Procedure

Regarding Wiring Diagram information, refer to WIRING DIAGRAM .

1. CHECK PUSH-BUTTON IGNITION SWITCH SIGNAL (PUSH-BUTTON IGNITION SWITCH)
   
   

   Check voltage between push-button ignition switch connector M38 and ground.

   Push-button ignition switch		Ground	Voltage (Approx.)
   Connector	Terminal
   M38	8	-	Battery voltage

   Is the inspection result normal?

   YES 

   GO TO STEP 2  .

   NO 

   GO TO STEP 3  .

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

   Check voltage between IPDM E/R connector E63 and ground.

   IPDM E/R		Ground	Voltage (Approx.)
   Connector	Terminal
   E63	38	-	Battery voltage

   Is the inspection result normal?

   YES 

   Replace IPDM E/R. Refer to REMOVAL AND INSTALLATION .

   NO 

   Repair or replace harness or connectors.

3. CHECK PUSH-BUTTON IGNITION SWITCH SIGNAL CIRCUIT (PUSH-BUTTON IGNITION SWITCH)
   
   
   1. Place push-button ignition switch in OFF position.
   2. Disconnect push-button ignition switch connector, IPDM E/R connector E63 and BCM connector M17.
   3. Check continuity between BCM connector M17 and push-button ignition switch connector M38.

      BCM		Push-button ignition switch		Continuity
      Connector	Terminal	Connector	Terminal
      M17	1	M38	8	Yes

   4. Check continuity between IPDM E/R connector E63 terminal 38 and ground.

      BCM		Ground	Continuity
      Connector	Terminal
      M17	1	-	No

   Is the inspection result normal?

   YES 

   Replace BCM. Refer to REMOVAL AND INSTALLATION .

   NO 

   Repair or replace harness or connectors.
