OUTLINE
• Mobile valve shade type is adopted. Xenon headlamp switches the high beam and the low beam with one
xenon bulb each on right and left.
• Headlamp is controlled by combination switch reading function and headlamp control function of BCM, and
relay control function of IPDM E/R.
HEADLAMP BASIC 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 ON condition.
Headlamp ON condition
- Lighting switch 2ND
- Lighting switch PASS
- Lighting switch AUTO, and the auto light function ON judgment (With auto light system)
• IPDM E/R turns the integrated headlamp low relay ON, and turns the headlamp ON according to the low
beam request signal.
HEADLAMP HI/LO SWITCHING OPERATION
• BCM transmits the high beam request signal to IPDM E/R and the combination meter with CAN communica-
tion according to the high beam switching condition.
High beam switching 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.

• When the headlamp high relay is turned ON, magnetic force is
applied to the high beam solenoid (1) by a current. The mobile
valve shade (3) is switched to the high beam position through the
actuator rod (2).
• When the headlamp high relay is turned OFF, the current stops.
The mobile valve shade returns to the low beam position automati-
cally.

Part
Description
BCM
• Detects each switch condition by the combination switch reading function.
• 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/R
Controls the integrated relay, and supplies voltage to the load according to the request
from BCM (with CAN communication).
Combination switch
(Lighting & turn signal switch)
Combination meter
(High beam indicator lamp)
Turns the high beam indicator lamp ON according to the request from BCM (with CAN
communication).
