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.

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/RControls the integrated relay, and supplies voltage to the load according to the request
from BCM (with CAN communication).
Combination switch
(Lighting & turn signal switch)Refer to BCS-8, "
System Diagram".
Combination meter
(High beam indicator lamp)Turns the high beam indicator lamp ON according to the request from BCM (with CAN
communication).
