   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.
