Diagnosis Procedure

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

1. CHECK HOOD SWITCH SIGNAL CIRCUITS 
   1. Turn ignition switch OFF.
   2. Disconnect hood switch connector.
   3. Check voltage between hood switch harness connector and ground.

      (+)		(-)	Voltage (V) (Approx.)
      Hood switch
      Connector	Terminal
      E205	1	Ground	12
      	2

      Is the inspection result normal? 

      YES: GO TO  3.

      NO: GO TO 2.

2. CHECK HOOD SWITCH SIGNAL CIRCUITS 
   1. Disconnect IPDM E/R connector.
   2. Check continuity between IPDM E/R harness connector and hood switch harness connector.

      IPDM E/R		Hood switch		Continuity
      Connector	Terminal	Connector	Terminal
      E218	94	E205	1	Yes
      	96		2

   3. Check continuity between IPDM E/R harness connector and ground.

      IPDM E/R		Ground	Continuity
      Connector	Terminal
      E218	94		No
      	96

      Is the inspection result normal? 

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

      NO: Repair or replace harness.

3. CHECK HOOD SWITCH GROUND CIRCUIT 

   Check continuity between hood switch harness connector and ground.

   Hood switch		Ground	Continuity
   Connector	Terminal
   E205	3		Yes

   Is the inspection result normal? 

   YES: GO TO 4.

   NO: Repair or replace harness.

4. CHECK HOOD SWITCH 

   Refer to "COMPONENT INSPECTION ".

   Is the inspection result normal? 

   YES: GO TO 5.

   NO: Replace hood switch. Refer to "HOOD LOCK RELEASE CABLE: REMOVAL AND INSTALLATION ".

5. CHECK INTERMITTENT INCIDENT 

   Refer to "INTERMITTENT INCIDENT ".

   : Inspection End.
