24, located in the fuse block (J/B)]. Refer to PG-79,
"FUSE BLOCK - JUNCTION BOX (J/B)" .

If OK, check harness for open circuit. Repair or replace if necessary.

If NG, replace fuse and check harness for short circuit. Repair or replace if necessary.
2. CHECK GROUND CIRCUIT FOR BLOWER MOTOR
1. Turn ignition switch OFF.
2. Turn fan switch to 1-speed.
3. Check continuity between blower motor harness connector M65
terminal 2 (L/B) and ground.
OK or NG
OK >> GO TO 3.
NG >> GO TO 4.
3. CHECK BLOWER MOTOR
Refer to MTC-18, "
Blower Motor" .
OK or NG
OK >> INSPECTION END
NG >> Replace blower motor.

CHARGING SYSTEM PFP:00011
System Description EKS00316
The alternator provides DC voltage to operate the vehicle's electrical system and to keep the battery charged.
The voltage output is controlled by the IC regulator.
Power is supplied at all times

through 10A fuse (No. 34, located in the fuse and fusible link box)

to alternator terminal 4 (“S” terminal).
“B” terminal supplies power to charge the battery and operate the vehicle's electrical system. Output voltage is
controlled by the IC regulator at terminal 4 (“S” terminal) detecting the input voltage. The charging circuit is
protected by the 120A (Gasoline engine models) or 100A (Diesel engine models) fusible link (letter A, located
in the fuse and fusible link box).
The alternator is grounded to the engine block.
With the ignition switch in the ON or START position, power is supplied

through 10A fuse [No. 11, located in the fuse block (J/B)]

to combination meter terminal 2 for the charge warning lamp.
Ground is supplied with power and ground supplied

to terminal 5 of the combination meter

through alternator terminal 3 (“L” terminal)

to alternator terminal E (Gasoline engine models) or through body ground (Diesel engine models)

through ground E30 (Gasoline engine models).
The charge warning lamp will illuminate. When the alternator is providing sufficient voltage with the engine
running, the ground is opened and the charge warning lamp will go off.
If the charge warning lamp illuminates with the engine running, a malfunction is indicated.

With the ignition switch in the START position, power is supplied

from ignition switch terminal 5

to starter motor harness connector terminal 1.
The starter motor plunger closes and provides a closed circuit between the battery and starter motor. The
starter motor is grounded to the engine block. With power and ground supplied, cranking occurs and the
engine starts.

With the ignition switch in the ON or START position, power is supplied

through 10A fuse [No. 13, located in the fuse block (J/B)]

to park/neutral position relay terminal 1.
With the selector lever in the P or N position, ground is supplied

to park/neutral position relay terminal 2

through the park/neutral position switch terminals 1 and 2, and

through grounds F9 and F10.
Then park/neutral position relay is energized and power is supplied

from park/neutral position relay terminal 3

to starter motor harness connector terminal 1.
The starter motor plunger closes and provides a closed circuit between the battery and starter motor. The
starter motor is grounded to the engine block. With power and ground supplied, cranking occurs and the

HEADLAMP (LOWER SIDE), FOR HIGH BEAM
1. Turn lighting switch OFF.
2. Disconnect the battery cable from the negative terminal or remove power fuse.
3. Disconnect headlamp connector.
4. Remove air cleaner duct (when replacing LH bulb). Refer to EM-16, "
AIR CLEANER AND AIR DUCT" ,
EM-142, "
AIR CLEANER AND AIR DUCT" (QR), EM-142, "AIR CLEANER AND AIR DUCT" (YD22) in
“ENGINE MECHANICAL (EM)” section.
5. Turn plastic cap counterclockwise and unlock it.
6. Disconnect terminal connected to bulb.
7. Unlock retaining spring and remove bulb from headlamp.
8. Installation is the reverse order of removal.
CLEARANCE LAMP
1. Turn lighting switch OFF.
2. Disconnect headlamp connector.
3. Turn bulb socket counterclockwise and unlock it.
4. Remove bulb from headlamp.
5. Installation is the reverse order of removal.
CAUTION:

Never touch glass of bulb directly by hand. Keep grease and other oily matters away from it.

Never touch bulb by hand while it is lit or right after being turned off. Burning may result.

Never leave bulb out of headlamp reflector for a long time because dust, moisture, smoke, etc.
may affect the performance of headlamp. When replacing bulb, be sure to replace it with new one.

When bulb is installed, be sure to install plastic cap and bulb socket securely to ensure watertight-
ness.
Bulb Replacement of Driving LampEKS00N52
1. Remove driving lamp. Refer to LT- 2 3 , "Removal and Installation
of Driving Lamp" in “HEADLAMP -XENON TYPE-”.
2. Disconnect driving lamp connector.
3. Turn bulb socket counterclockwise and unlock it.
4. Installation is the reverse order of removal.
CAUTION:

Never touch glass of bulb directly by hand. Keep grease
and other oily matters away from it. Never touch bulb by
hand while it is lit or right after being turned off. Burning
may result.

When replacing bulb, prepare new bulb first of all. Never leave bulb out of driving lamp housing
for a long period, because dust, moisture or smoke will cause performance lowering (fouling,
cloud, etc.) of driving lamp reflector and lens.
