POWER SUPPLY ROUTING

Fuse EKS00324

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 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.
Fusible Link EKS00325
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 mal-
function.

Never wrap outside of fusible link with vinyl tape. Important:
Never let fusible link touch any other wiring harness, vinyl
or rubber parts.
Circuit Breaker EKS00326
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 CONNECTOR (SLIDE-LOCKING TYPE)

A new style slide-locking type connector is used on certain systems and components, especially those
related to OBD.

The slide-locking type connectors help prevent incomplete locking and accidental looseness or discon-
nection.

The slide-locking type connectors are disconnected by pushing or pulling the slider. Refer to the figure
below.
CAUTION:

Do not pull the harness or wires when disconnecting the connector.

Be careful not to damage the connector support bracket when disconnecting the connector.
