HEADLAMP SYSTEM
System DiagramINFOID:0000000003774356
System DescriptionINFOID:0000000003774357
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 (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.

AUTO LIGHT SYSTEM
System DiagramINFOID:0000000003773527
System DescriptionINFOID:0000000003773528
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-28, "
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).

< FUNCTION DIAGNOSIS >[XENON TYPE]
AUTO LIGHT SYSTEM
 Turns the exterior lamp OFF with the ignition switch ACC or the light switch OFF.
*: The preset time is 45 seconds. The timer operating time can be set by CONSULT-III. Refer to EXL-28,
"HEADLAMP : CONSULT-III Function (BCM - HEAD LAMP)".
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.

HEADLAMP AIMING CONTROL SYSTEM (AUTO)
System DiagramINFOID:0000000003774320
System DescriptionINFOID:0000000003774321
OUTLINE
 Headlamp aiming control system is controlled by auto levelizer control unit.
 Auto levelizer control unit controls the headlamp light axis height appropriately depending on the vehicle rear
height.
 Auto levelizer control unit detects the vehicle condition necessary for the aiming motor control with the fol-
lowing signals.
- Sensor lever signal (detected by the sensor lever)
- Tail lamp signal (inputted from IPDM E/R)
- Vehicle speed signal (8-pulse) (inputted from combination meter)
HEADLAMP AUTO AIMING OPERATION
 Auto levelizer control unit calculates vehicle pitch angle from sensor lever signal and determines the neces-
sary correction to compensate the deviation from standard light axis position.
 Auto levelizer control unit outputs aiming motor drive signal when operating conditions are satisfied.
Operating condition
- Ignition switch ON
- Tail lamp ON
 Auto levelizer control unit changes the aiming motor drive signal when any of the correcting condition is
detected. Output is maintained if other condition is detected.
Correcting condition- Tail lamp is turned ON.
- Vehicle posture becomes stable after the vehicle posture change is detected with the tail lamp ON and the
vehicle stopped.
- Vehicle speed is maintained with the tail lamp ON and the vehicle driven.
CAUTION:
Adjusted axis position may differ from the preset position although the headlamp auto aiming acti-
vates properly when the suspension is replaced or worn.

fog lamp ON condition.
Front fog lamp ON condition
- Front fog lamp switch ON
- Lighting switch 1ST, 2ND or AUTO (auto light function ON judgment)
 IPDM E/R turns the integrated front fog lamp relay ON, and turns the front fog lamp ON according to the
front fog light request signal.
