Fuse EKS002LO
● If fuse is blown, be sure to eliminate cause of incident before
installing new fuse.
● Use fuse of specified rating. Never use fuse of more than speci-
fied 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.
CEL083
Fusible Link EKS002LP
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 inci-
dent.
● Never wrap outside of fusible link with vinyl tape. Important:
Never let fusible link touch any other wiring harness, vinyl
or rubber parts. CKIH0002E
Circuit Breaker EKS002LQ
The PTC thermistor generates heat in response to current flow. The
temperature (and resistance) of the thermistor element varies with
current flow. Excessive current flow will cause the element's temper-
ature to rise. When the temperature reaches a specified level, the
electrical resistance will rise sharply to control the circuit current.
Reduced current flow will cause the element to cool. Resistance falls
accordingly and normal circuit current flow is allowed to resume.

Harness Layout EKS002OJ
HOW TO READ HARNESS LAYOUTS
The following Harness Layouts use a map style grid to help locate
connectors on the drawings:
● Main Harness
● Engine Room Harness (Engine Compartment)
● Engine Control Harness
● Body Harness and Rear Control Harness
● Body No.2 Harness
To use the grid reference
1. Find the desired connector number on the connector list.
SEL252V
2. Find the grid reference.
3. On the drawing, find the crossing of the grid reference letter column and number row.
4. Find the connector number in the crossing zone.
5. Follow the line (if used) to the connector.
CONNECTOR SYMBOL
Main symbols of connector (in Harness Layout) are indicated in the below.
