Aiming Adjustment

AKS005LC

The fog lamp is a semi-sealed beam type which uses a replaceable halogen bulb. Before performing aiming
adjustment, make sure of the following.

●

Keep all tires inflated to correct pressure.

●

Place vehicle on level ground.

●

See that vehicle is unloaded (except for full levels of coolant,
engine oil and fuel, and spare tire, jack, and tools). Have the
driver or equivalent weight placed in driver seat.

Adjust aiming in the vertical direction by turning the adjusting screw.

Set the distance between the screen and the center of the fog
lamp lens as shown at left.

Turn front fog lamps ON.

Adjust front fog lamps using adjusting screw so that the top edge
of the high intensity zone is in the hatched area as shown in the
figure.

●

When performing this adjustment, cover the headlamps and
the opposite fog lamp, if necessary.

COMBINATION SWITCH READING FUNCTION

Refer to

LT-251, "Combination Switch Reading Function"

CAN Communication System Description

AKS004KC

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.
