Replacing the fuses
The main fuse box is located above the
battery.
The fuse box, which contains the fuses
for the individual circuits, is located in
the storage compartment. (See
page 3-10.)If a fuse is blown, replace it as follows.
1. Turn the key to “OFF” and turn off
the electrical circuit in question.
2. Remove the blown fuse, and then
install a new fuse of the specified
amperage.
CAUTION:

ECAT1061

Do not use a fuse of a higher
amperage rating than recom-
mended to avoid causing exten-
sive damage to the electrical
system and possibly a fire.

After removing and installing
the main fuse, be sure to turn
the main switch from “ON” to
“OFF” three times in 3 seconds
intervals to initialize the idle
speed control system.
3. Turn the key to “ON” and turn on
the electrical circuit in question to
check if the device operates.
