ELECTRICAL UNITS LOCATION
Fuse
EKS00LJB
lIf fuse is blown, be sure to eliminate cause of incident before
installing new fuse.
lUse fuse of specified rating. Never use fuse of more than speci-
fied rating.
lDo not partially install fuse; always insert it into fuse holder prop-
erly.
lRemove fuse for “ELECTRICAL PARTS (BAT)” if vehicle is not
used for a long period of time.
Fusible LinkEKS00LJC
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:
lIf 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 incident.
lNever wrap outside of fusible link with vinyl tape.
lNever let fusible link touch any other wiring harness, vinyl or rubber parts.
Circuit Breaker (Built Into BCM)EKS00LJD
For example, when current is 30A, the circuit is broken within 8 to 20
seconds.
A circuit breaker is used for the following systems:
lPower seat
lPower windows
lPowerdoorlocks
lRemote keyless entry system
lPower sunroof
lRear window wiper

CHARGING SYSTEM
INSPECTION OF INSUFFICIENT ALTERNATOR POWER GENERATION
CAUTION:
Check them using charged battery performed battery inspection.
1.VOLTAGE INSPECTION
1. Increase engine speed to 2,500 rpm.
2. Turn electrical load to ON. (Headlamp LO turns on, blower fan
motor maximum airflow amount)
3. Check battery voltage.
Is the inspection result 12.8V to 15.1V?
YES >> GO TO 2.
NO >> Replace alternator. (Alternator power generation error.)
2.CURRENT INSPECTION
1. Turn ignition switch OFF.
2. Disconnect the battery ground cable.
3. Attach current measurement probe for CONSULT-II to the harness for alternator terminal B.
(If the probe can not be attached properly, then connect the sub-
harness between alternator terminal B and the vehicle side har-
ness as shown in figure, and attach the probe to sub-harness.)
4. Connect battery ground cable.
5. Increase engine speed to 2,500 rpm.
6. Turn electrical load to ON. (Headlamp LO turns on, blower fan
motor maximum airflow amount, rear window defogger)
7. Check alternator terminal B current.
CAUTION:
Be careful of rotating parts because the engine is running.
Is the inspection result 30A or more?
YES >> GO TO dark current inspection. Refer toSC-21, "DARK CURRENT INSPECTION". (Alternator is
normal. Do not replace.)
NO >> Replace alternator. (Alternator power generation error.)
INSPECTION OF EXCESSIVE ALTERNATOR POWER GENERATION
1.ALTERNATOR VOLTAGE INSPECTION
1. Increase engine speed to 2,500 rpm.
2. Check battery voltage.
Is the inspection result 16V or less?
YES >> GO TO 2.
NO >> Replace alternator. (Excessive alternator power genera-
tion.)
