HEADLAMP
HEADLAMP
PFP:26010
System DescriptionEKS003CD
DESCRIPTION
The headlamps are controlled by the lighting switch which is built into the combination switch.
Power is supplied at all times
lto lighting switch terminal 8
lthrough 15A fuse (No. 40, located in the fuse and fusible link box), and
lto lighting switch terminal 5
lthrough 15A fuse (No. 41, located in the fuse and fusible link box).
LOW BEAM OPERATION
When the lighting switch is turned to the 2ND position and placed in LOW (“B”) position, power is supplied
lfrom lighting switch terminal 10
lto terminal 3 of the headlamp LH, and
lfrom lighting switch terminal 7
lto terminal 3 of the headlamp RH.
Terminal 2 of each headlamp supplies ground through body grounds E24 and E50.
With power and ground supplied, the low beams will illuminate.
HIGH BEAM OPERATION/FLASH-TO-PASS OPERATION
When the lighting switch is turned to the 2ND position and placed in HIGH (“A”) position or PASS (“C”) posi-
tion, power is supplied
lfrom lighting switch terminal 6
lto terminal 1 of headlamp RH, and
lfrom lighting switch terminal 9
lto terminal 1 of headlamp LH, and
lto combination meter terminal 61 (LHD models) or 50 (RHD models) for the HIGH BEAM indicator.
Ground is supplied to terminal 60 (LHD models) or 49 (RHD models) of the combination meter through body
grounds M27 and M70.
Ground is supplide to terminal 2 of each headlamp through body grounds E24 and E50.
With power and ground supplied, the high beams and the HIGH BEAM indicator illuminate.

Aiming AdjustmentEKS003CG
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.
lKeep all tires inflated to correct pressures.
lPlace vehicle and tester on one and same flat surface.
lSee 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).
