Aiming Adjustment
EKS00P7Y
For details, refer to the regulations in your state.
Before performing aiming adjustment, check the following.
1. Ensure all tires are inflated to correct pressure.
2. Place vehicle and screen on level surface.
3. Ensure there is no load in vehicle other than the driver (or equivalent weight placed in driver's position).
Coolant and engine oil filled to correct level, and fuel tank full.
4. Confirm spare tire, jack and tools are properly stowed.
LOW BEAM AND HIGH BEAM
NOTE:
Aim each headlamp individually and ensure other headlamp beam pattern is blocked from screen.
1. Turn headlamp low beam ON.
2. Use adjusting screws to perform aiming adjustment.
lFirst tighten the adjusting screw all the way and then make adjustment by loosening the screw.
If the vehicle front body has been repaired and/or the headlamp assembly has been replaced, check
aiming. Use the aiming chart shown in the figure.

lFigure shows headlamp aiming pattern for driving on right
side of road; for driving on left side of road, aiming pattern is
reversed.
lDotted lines to point P in illustration show center of head-

lElbow point for LHD models must be in 125 mm (4.92 in) to
the right form point P.
Elbow point for RHD models must be in 125 mm (4.92 in) to
the left form point P.
lBasic illuminating area for adjustment should be within the
range shown in the figure. Adjust headlamps accordingly.
CAUTION:
Be sure aiming switch is set to “0” when preforming aiming
adjustment.

HEADLAMP - DAYTIME LIGHT SYSTEM -PFP:26010
Component Parts and Harness Connector LocationEKS00Q7E
System DescriptionEKS00Q7F
The daytime light system is to illuminate headlamp low beam, clearance lamps, tail lamps and license plate
lamps while the engine is running.
When the engine is running, the BCM (body control module) receives the engine status signal. Then the BCM
sends the headlamp low beam request signal and the daytime light request signal to the IPDM E/R (intelligent
power distribution module engine room) through the CAN communication. As the IPDM E/R receives the
above request signals, its CPU (central processing unit) controls headlamp low relay to illuminate headlamp
low beam, clearance lamps, tail lamps and license plate lamps.

DAYTIME LIGHT OPERATION
With the lighting switch in the OFF position and engine running, the BCM receives input signal requesting
headlamp low beam, clearance lamp, license plate lamp, and tail lamp to illuminate. This input signal is com-
municated to the IPDM E/R through the CAN communication. The CPU located in the IPDM E/R controls
headlamp low relay.
