Aiming Adjustment for HeadlampEKS003CG
When performing headlamp aiming adjustment, use an aiming machine, aiming wall screen or headlamp
tester. Aimers should be in good repair, calibrated and operated in accordance with respective operation man-
uals.
If any aimer is not available, aiming adjustment can be done as follows:
For details, refer to the regulations in your own country.

Keep all tires inflated to correct pressures.

Place vehicle and tester on one and same flat surface.

See that there is no-load in vehicle (coolant, engine oil filled up to correct level and full fuel tank) other
than the driver (or equivalent weight placed in driver's position).
CAUTION:
Be sure aiming switch is set to “0” when performing aiming adjustment.

HEADLAMP - DAYTIME LIGHT SYSTEM -

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
