PREPARATION BEFORE ADJUSTING
NOTE:
 For details, refer to the regulations in your own country.
Before performing aiming adjustment, check the following.
 Adjust the tire pressure to the specification.
 Fill with fuel, engine coolant and each oil.
 Maintain the unloaded vehicle condition. (Remove luggage from the passenger compartment and the lug-
gage room.)
NOTE:
Do not remove the temporary tire, jack and on-vehicle tool.
 Wipe out dirt on the headlamp.
CAUTION:
Never use organic solvent (thinner, gasoline etc.)
 Ride alone on the driver seat.
AIMING ADJUSTMENT SCREW
 Turn the aiming adjusting screw for adjustment.
 For the position and direction of the adjusting screw, refer to the
figure.
NOTE:
A screwdriver or hexagonal wrench [6 mm (0.24 in)] can be used
for adjustment.
Aiming Adjustment ProcedureINFOID:0000000003773618
1. Place the screen.
NOTE:
 Stop the vehicle facing the wall.
 Place the board on a plain road vertically.
2. Face the vehicle with the screen. Maintain 10 m (32.8 ft) between the front fog lamp center and the
screen.
3. Start the engine. Illuminate the front fog lamp.
CAUTION:
Never cover the lens surface with a tape etc. The lens is made of resin.
NOTE:
Shut off the headlamp light with the board to prevent from illuminating the adjustment screen.
4. Adjust the cutoff line height (A) with the aiming adjustment screw so that the distance (X) between the hor-
izontal center line of front fog lamp (H) and (A) becomes 200 mm (7.87 in).

FUNCTION DIAGNOSIS
HEADLAMP SYSTEM
System DiagramINFOID:0000000003773647
System DescriptionINFOID:0000000003773648
OUTLINE
Headlamp is controlled by combination switch reading function and headlamp control function of BCM, and
relay control function of IPDM E/R.
HEADLAMP (LO) OPERATION
 BCM detects the combination switch condition with the combination switch reading function.
 BCM transmits the low beam request signal to IPDM E/R with CAN communication according to the head-
lamp (LO) ON condition.
Headlamp (LO) ON condition- Lighting switch 2ND
- Lighting switch AUTO, and the auto light function ON judgment (With auto light function ON judgment)
 IPDM E/R turns the integrated headlamp low relay ON, and turns the headlamp ON according to the low
beam request signal.
HEADLAMP (HI) OPERATION
 BCM transmits the high beam request signal to IPDM E/R and the combination meter with CAN communica-
tion according to the headlamp (HI) ON condition.
Headlamp (HI) ON condition- Lighting switch HI with the lighting switch 2ND or AUTO (auto light function ON judgment)
- Lighting switch PASS
 Combination meter turns the high beam indicator lamp ON according to the high beam request signal.
 IPDM E/R turns the integrated headlamp high relay ON, and turns the headlamp ON according to the high
beam request signal.

 Judges that the headlamp is turned ON according to the vehicle condition.
- Requests the headlamp relay (HI/LO) ON to IPDM E/R (with CAN communication).
- Requests the high beam indicator lamp ON to the combination meter (with CAN
communication).
IPDM E/RControls the integrated relay, and supplies voltage to the load according to the request
from BCM (with CAN communication).

AUTO LIGHT SYSTEM
AUTO LIGHT SYSTEM
System DiagramINFOID:0000000003894281
System DescriptionINFOID:0000000003894282
OUTLINE
 Auto light system is controlled by each function of BCM and IPDM E/R.
Control by BCM- Combination switch reading function
- Headlamp control function
- Auto light function
- Delay timer function
Control by IPDM E/R- Relay control function
 Auto light system has the auto light function and the delay timer function.
- Auto light function turns the exterior lamps* and each illumination ON/OFF automatically according to the
outside brightness.
- When auto light system turns the exterior lamps ON with the ignition switch OFF, delay timer function turns
the exterior lamps OFF depending on the vehicle condition with the auto light function after a certain period
of time.
*: Headlamp (LO/HI), parking lamp, tail lamp and front fog lamp (Headlamp HI and front fog lamp depend on
the combination switch condition.)
AUTO LIGHT FUNCTION
 BCM detects the combination switch condition with the combination switch reading function.
 BCM supplies voltage to optical sensor when the ignition switch is turned ON or ACC.
 Optical sensor converts outside brightness (lux) to voltage and transmits the optical sensor signal to BCM.
 BCM judges outside brightness from the optical sensor signal and judges ON/OFF condition of the exterior
lamp and each illumination according to the outside brightness.
 BCM transmits each request signal to IPDM E/R with CAN communication according to ON/OFF condition
by the auto light function.
NOTE:
ON/OFF timing differs based on the sensitivity from the setting. The setting can be set by CONSULT-III. Refer
to EXL-215, "
HEADLAMP : CONSULT-III Function (BCM - HEAD LAMP)".
DELAY TIMER FUNCTION
BCM turns the exterior lamp OFF depending on the vehicle condition with the auto light function when the igni-
tion switch is turned OFF.
 Turns the exterior lamp OFF 5 minutes after detecting that any door opens (Door switch ON).
 Turns the exterior lamp OFF a certain period of time* after closing all doors (Door switch ON→OFF).

NOTE:
When any position other than the light switch AUTO is set, the auto light system function switches to the exte-
rior lamp battery saver function.
