   Connector	Terminal
   D38	10	Ground	Battery voltage

   Is the measurement value within the specification? 

   YES: GO TO  3.

   NO: GO TO 2.

2. CHECK POWER SUPPLY CIRCUIT 2
   1. Turn ignition switch OFF.
   2. Disconnect BCM connector.
   3. Check continuity between BCM harness connector and power window sub-switch harness connector.

   Is the inspection result normal? 

   YES: Replace BCM. Refer to "EXPLODED VIEW "

   NO: Repair or replace harness.

3. CHECK GROUND CIRCUIT

Check continuity between power window sub-switch harness connector and ground.

Is the inspection result normal? 

YES: INSPECTION END

NO: Repair or replace harness.
