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

Trouble DiagnosesEKS00319
Before performing an alternator test, make sure that the battery is fully charged. A 30-volt voltmeter and suit-
able test probes are necessary for the test. The alternator can be checked easily by referring to the Inspection
Table.
Before starting, inspect the fusible link.
Use fully charged battery.
WITH IC REGULATOR
NOTE:
If the inspection result is OK even though the charging system is malfunctioning, check the B terminal
connection. (Check the tightening torque and voltage drop.)
Check condition of rotor coil, rotor slip ring, brush and stator coil. If necessary, replace faulty parts with
new ones.
MALFUNCTION INDICATOR
The IC regulator warning function activates to illuminate “CHARGE” warning lamp, if any of the following
symptoms occur while alternator is operating:
Excessive voltage is produced.
No voltage is produced.

HEADLAMP - DAYTIME LIGHT SYSTEM -PFP:26010
System DescriptionEKS003BB
DESCRIPTION
The headlamp system on vehicles for North Europe contains a daytime light control unit. The unit activates the
following whenever the engine is running with the lighting switch in the OFF position:
Low beam headlamps
Parking, license, tail and illumination lamps
Power is supplied at all times
through 10A fuse (No. 31, located in the fuse and fusible link box)
to daytime light control unit terminal 1 and
to lighting switch terminal 11.
Power is also supplied at all times
through 15A fuse (No. 41, located in the fuse and fusible link box)
to daytime light control unit terminal 3 and
to lighting switch terminal 5.
Power is also supplied at all times
through 15A fuse (No. 40, located in the fuse and fusible link box)
to daytime light control unit terminal 2 and
to lighting switch terminal 8.
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 daytime light control unit terminal 7.
With the ignition switch in the START position, power is supplied
through 10A fuse [No. 7, located in the fuse block (J/B)]
to daytime light control unit terminal 6.
HEADLAMP OPERATION (DAYTIME LIGHT CANCEL OPERATION)
When the lighting switch is turned to the 1st or 2nd position, power is supplied
through lighting switch terminal 12
to daytime light control unit terminal 11.
Then daytime light will be canceled. And the lighting system operation will be the same as no daytime light
system.
DAYTIME LIGHT OPERATION
With the engine running and the lighting switch in the OFF position, power is supplied
from alternator terminal 3
to daytime light control unit terminal 8,
through daytime light control unit terminal 5
to terminal 3 of headlamp LH,
through daytime light control unit terminal 4
to terminal 3 of headlamp RH and
through daytime light control unit terminal 10
to tail lamp and illumination.
Ground is supplied to terminal 2 of each headlamp through body grounds E24 and E50.
DRIVING LAMP OPERATION
To turn the driving lamp on, push the driving lamp switch when the lighting switch is turned to the 2ND position
and placed in HIGH position or PASS position, power is supplied
from lighting switch terminal 9
to headlamp LH terminal 1
to driving lamp relay-1 terminal 1
