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

Regarding Wiring Diagram information, refer to "WIRING DIAGRAM - COUPE " or "WIRING DIAGRAM - SEDAN ".

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, 2	Battery power supply	B, D
   -		42
   		43

   Is the fuse blown? 

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

   NO: GO TO 2

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

      Terminals			Voltage (V) (Approx.)

      Is the measurement value normal? 

      YES: GO TO 3

      NO: Repair harness or connector.

3. CHECK GROUND CIRCUIT

   Check continuity between IPDM E/R harness connectors and ground.

   IPDM E/R		Ground	Continuity
   Connector	Terminal
   A: E18	12		Yes
   B: E17	41

   Does continuity exist? 

   YES: Inspection End.

   NO: Repair harness or connector.
