CAN COMMUNICATIONPFP:23710
System DescriptionEKS001U3
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2
communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.

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.

2. Use adjusting screws to perform aiming adjustment.

First 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.

Adjust headlamps so that main axis of light is parallel to cen-
ter line of body and is aligned with point P shown in illustra-
tion.

Figure to the right shows headlamp aiming pattern for driving
on right side of road; for driving on left side of road, aiming
pattern is reversed.

Dotted lines to point P in illustration show center of head-
lamp.

Basic illuminating area for adjustment should be within the
range shown at right. Adjust headlamps accordingly.
CAUTION:
Be sure aiming switch is set to “0” when preforming aiming
adjustment.
Aiming Adjustment for Driving LampEKS00AP6

Turn the aiming adjusting screw to adjust.

For positions of the adjustment screws and direction to turn,
refer to the figures.

When adjusting for right or left side, adjust upper and lower
adjustment screws at the same time.
PREPARATION BEFORE ADJUSTING
For details, refer to the regulations in your own country.
Before performing aiming adjustment, check the following.
1. Keep all tires inflated to correct pressures.
2. Place vehicle on level ground.
3. Set that there is no-load in vehicle other than the driver (or equivalent weight placed in driver's position),
coolant, engine oil filled up to correct level, full fuel tank and spare tire, jack, and tools."H" : Horizontal center line of headlamps
