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

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

1. CHECK FUSES AND FUSIBLE LINK

   Check that the following IPDM E/R fuses or fusible link are not blown.

   Terminal No.	Signal name	Fuses and fusible link No.
   1	Battery	A, D
   2	Battery	C

   Is the fuse blown? 

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

   NO: GO TO 2

2. CHECK BATTERY POWER SUPPLY CIRCUIT
   1. Turn ignition switch OFF.
   2. Disconnect IPDM E/R.
   3. Check voltage between IPDM E/R harness connectors and ground.

      Terminals			Ignition switch position
      (+)		(-)	OFF	ON	START
      Connector	Terminal
      E118	1	Ground	Battery voltage	Battery voltage	Battery voltage
      	2		Battery voltage	Battery voltage	Battery voltage

   Is the measurement value normal? 

   YES: GO TO 3

   NO: Repair or replace harness.

3. CHECK GROUND CIRCUIT
   1. Turn ignition switch OFF.
   2. Check continuity between IPDM E/R harness connectors and ground.

      IPDM E/R		Ground	Continuity
      Connector	Terminal
      E122 (A)	38		Yes
      E124 (B)	59
