IPDM E/R (INTELLIGENT POWER DISTRIBUTION MODULE ENGINE ROOM): Diagnosis Procedure

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

1. CHECK FUSIBLE LINKS 

   Check that the following fusible links are not blown.

   Terminal No.	Signal name	Fusible link No.
   1	Fusible link main	E (80A)
   2	Fusible link IPDM E/R	A (250A), C (80A)
   3	Fusible link ignition switch	A (250A), B (100A), K (40A)

   Is the fusible link blown? 

   YES: Replace the blown fusible link after repairing the affected circuit.

   NO: GO TO 2

2. CHECK POWER SUPPLY CIRCUIT 
   1. Disconnect IPDM E/R connectors E118 and E120.
   2. Check voltage between IPDM E/R connectors and ground.

      IPDM E/R		Ground	Voltage (Approx.)
      Connector	Terminal
      E118	1	-	Battery voltage
      	2
      E120	3

      Is the inspection result normal? 

      YES: GO TO 3

      NO: Repair or replace harness or connectors.

3. CHECK GROUND CIRCUIT 
   1. Disconnect IPDM E/R connectors E119 and E121.
   2. Check continuity between IPDM E/R connectors and ground.

      IPDM E/R		Ground	Continuity
      Connector	Terminal
      E121	7	-	Yes
      E119	41

      Is the inspection result normal? 

      YES: Inspection End.

      NO: Repair or replace harness or connectors.
