Fuse
INFOID:0000000005146579
• If fuse is blown, be sure to eliminate cause of malfunction before installing new fuse.
• Use fuse of specified rating. Never use fuse of more than specified
rating.
• Do not partially install fuse; always insert it into fuse holder prop- erly.
• Remove fuse for “ELECTRICAL PARTS (BAT)” if vehicle is not used for a long period of time.
Fusible LinkINFOID:0000000005146580
A melted fusible link can be detected either by visual inspection or by
feeling with finger tip. If its condition is questionable, use circuit
tester or test lamp.
CAUTION:
• If fusible link should melt, it is possible that critical circuit
(power supply or large current carrying circuit) is shorted. In
such a case, carefully check and eliminate cause of malfunc-
tion.
• Never wrap outside of fusible link with vinyl tape. Important: Never let fusible link touch an y other wiring harness, vinyl or
rubber parts.

POWER SUPPLY AND GROUND CIRCUIT
POWER WINDOW MAIN SWITCH
POWER WINDOW MAIN SWITCH : DescriptionINFOID:0000000005147171
• BCM supplies power.
• It operates each power window motor via corresponding power window switch and makes window move up/down when main power window and door lock/unlock switch is operated.
POWER WINDOW MAIN SWITCH : Component Function CheckINFOID:0000000005147172
Main Power Window And Door Lock/Unlock Switch
1. CHECK MAIN POWER WINDOW AND DO OR LOCK/UNLOCK SWITCH FUNCTION
Does power window motor operate with main power window and door lock/unlock switch operation?
Is the inspection result normal?
YES >> Main power window and door lock/unlock switch power supply and ground circuit are OK.
NO >> Refer to PWC-12, "
POWER WINDOW MAIN SWITCH : Diagnosis Procedure".
POWER WINDOW MAIN SWITCH : Diagnosis ProcedureINFOID:0000000005147173
Regarding Wiring Diagram information, refer to PWC-53, "Wiring Diagram".
1. CHECK POWER SUPPLY CIRCUIT
1. Turn ignition switch ON.
2. Check voltage between main power window and door lock/ unlock switch connectors and ground.
Is the measurement value within the specification?
YES >> GO TO 3
NO >> GO TO 2
2. CHECK HARNESS CONTINUITY
1. Turn ignition switch OFF.
2. Disconnect BCM and main power window and door lock/unlock switch.
3. Check continuity between BCM connector and main power win- dow and door lock/unlock switch connectors.
