Part

Function

1.

Optical sensor

Refer to

EXL-10, "Optical Sensor"

.

2.

LED headlamp control module

Turns the headlamps ON according to the power supply from IPDM E/R.

3.

Headlamp aiming motor

Moves the headlamps up/down based on inputs from the rear height sensor.

4.

Parking brake switch

Transmits the parking brake switch signal to the combination meter to operate the
daytime running light system.

5.

Front door switch LH (RH similar)

Transmits the door open signal to the BCM to operate the autolight system.

6.

Rear door switch LH (RH similar)

7.

Rear height sensor

Sends the vehicles pitch angle signal to the IPDM E/R necessary for adjusting the
headlamp aiming motors.

8.

Combination switch
(Lighting and turn signal switch)

Refer to

BCS-9, "COMBINATION SWITCH READING SYSTEM : System Descrip-

tion"

(with Intelligent Key system) or

BCS-81, "COMBINATION SWITCH READING

SYSTEM : System Description"

(without Intelligent Key system).

9.

Combination meter

Refer to

MWI-8, "METER SYSTEM : System Description"

.

10.

Hazard switch

Refer to

EXL-11, "Hazard Switch"

.

11.

IPDM E/R

• Supplies voltage to the load according to the request from BCM (via CAN com-

munication).

• Refer to

PCS-6, "Component Parts Location"

for detailed installation location.

12.

BCM

• Detects each switch condition by the combination switch reading function.
• Judges that the exterior lamps are turned ON according to the vehicle condition.
• Requests the headlamp (HI/LO), tail lamp and front fog lamp ON to IPDM E/R (via

CAN communication).

• Requests high beam indicator lamp ON to the combination meter (via CAN com-

munication).

• Judges the outside brightness from the optical sensor signal.
• Judges the ON/OFF timing according to the vehicle condition.
• Judges the ON/OFF status of the exterior lamp according to the outside bright-

ness and the vehicle condition.

• Refer to

BCS-7, "BODY CONTROL SYSTEM : Component Parts Location"

(with

Intelligent Key system) or

BCS-79, "BODY CONTROL SYSTEM : Component

Parts Location"

(without Intelligent Key system).

SYSTEM DIAGRAM

OUTLINE

Headlamp is controlled by combination switch reading function and headlamp control function of BCM, and

Smart FET 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)

- Lighting switch AUTO, with the front fog lamp switch ON and the ignition switch ON

- Lighting switch PASS

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

- Lighting switch AUTO, with the front fog lamp switch ON, the ignition switch ON and lighting switch HI

• Combination meter turns the high beam indicator lamp ON according to the high beam request signal.

• IPDM E/R turns the headlamp ON according to the high beam request signal.

HEADLAMP SYSTEM : Fail-Safe

INFOID:0000000011280707

CAN COMMUNICATION CONTROL

When CAN communication with BCM is impossible, IPDM E/R performs fail-safe control. After CAN communi-

cation recovers normally, it also returns to normal control.

If no CAN communication is available with BCM
