FUSE INSPECTION

How To Check

INFOID:0000000010464100

• 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.

EXTENDED STORAGE FUSE SWITCH (IF EQUIPPED)

The following switch may be mounted on the fuse block (Junction Box) for transportation and storage.

• Remove the extended storage fuse switch when replacing the fuse of extended storage fuse switch.
• Remove the extended storage fuse switch if it causes the interference when the fuse or the other fuses is

checked.

How To Extended Storage Fuse Switch ON/OFF 

CAUTION:

• Turn the ignition switch OFF when operating the extended storage fuse switch.
• Under normal conditions, keep the extended storage fuse switch in ON state. Never operate the

extended storage fuse switch except when necessary.

FUSIBLE LINK INSPECTION

How To Check

INFOID:0000000010464101

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 malfunction.

• Never wrap outside of fusible link with vinyl tape. Important: Never let fusible link touch any other

wiring harness, vinyl or rubber parts.
