HEADLAMP SYSTEM
HEADLAMP SYSTEM : System Description

INFOID:0000000009472853

SYSTEM DIAGRAM

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)

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

- Lighting switch PASS

• 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

- 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 integrated headlamp high relay ON, and turns the headlamp ON according to the high

beam request signal.

HEADLAMP SYSTEM : Fail-safe

INFOID:0000000009472855

CAN COMMUNICATION CONTROL

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

communication recovers normally, it also returns to normal control.

If No CAN Communication Is Available With BCM

HEADLAMP AIMING SYSTEM (MANUAL)
HEADLAMP AIMING SYSTEM (MANUAL) : System Diagram

INFOID:0000000009549365

HEADLAMP AIMING SYSTEM (MANUAL) : System Description

INFOID:0000000009549366

The headlamp aiming system (manual) controls the headlamp light axis height according to input from the

headlamp aiming switch. The variable internal resistance of the headlamp aiming switch controls the signal

ground of the headlamp aiming motors located on the front combination lamp LH and RH. The headlamp aim-

ing system operates when the combination switch (lighting and turn signal switch) is in the 2nd position. 

DAYTIME RUNNING LIGHT SYSTEM
DAYTIME RUNNING LIGHT SYSTEM : System Description

INFOID:0000000009472860

SYSTEM DIAGRAM

OUTLINE

• Daytime running lamp is controlled by daytime running lamp control function and combination switch reading

function of BCM, and relay control function of IPDM E/R.

DAYTIME RUNNING LAMP OPERATION 

• BCM detects the combination switch condition by the combination switch reading function.

• BCM detects the engine condition according to push-button ignition switch

• BCM detects the parking brake condition by the parking brake switch signal received from combination

meter using CAN communication.

• BCM transmits the daytime running lamp request signal to IPDM E/R using CAN communication according

to the daytime running lamp ON condition.

Fail-safe operation

Headlamp

• Turns ON the headlamp low relay when the ignition switch is turned ON
• Turns OFF the headlamp low relay when the ignition switch is turned OFF
• Headlamp high relay OFF

SYSTEM

- Engine running

- Lighting switch OFF or 1ST

- Lighting switch AUTO, and the auto light function OFF judgment

- Parking brake switch OFF

• IPDM E/R controls the daytime running lamp relay (ground-side) to turn ON according to the daytime run-

ning lamp request signal.

• Power is supplied from the daytime running lamp to the daytime running lamps.

TURN SIGNAL AND HAZARD WARNING LAMP SYSTEM
TURN SIGNAL AND HAZARD WARNING LAMP SYSTEM : System Description

INFOID:0000000009472862

SYSTEM DIAGRAM

OUTLINE

Turn signal and the hazard warning lamp is controlled by combination switch reading function, flasher control

function and auto hazard function of BCM.

TURN SIGNAL LAMP OPERATION

• BCM detects the combination switch condition by the combination switch reading function.

• BCM supplies voltage to the right (left) turn signal lamp circuit when the ignition switch is turned ON and the

turn signal switch is in the right (left) position. BCM blinks the turn signal lamp.

HAZARD WARNING LAMP OPERATION

BCM supplies voltage to both turn signal lamp circuit when the hazard switch is turned ON. BCM blinks the

hazard warning lamp.

HIGH FLASHER OPERATION

• BCM detects the turn signal lamp circuit status from the current value.

• BCM increases the turn signal lamp blinking speed if the bulb or harness open is detected with the turn sig-

nal lamp operating.

NOTE:

The blinking speed is normal while operating the hazard warning lamp.

SYSTEM DIAGRAM

OUTLINE

Parking, license plate, side marker and tail lamps are controlled by combination switch reading function and

headlamp control function of BCM, and relay control function of IPDM E/R.

PARKING, LICENSE PLATE, SIDE MARKER AND TAIL LAMPS OPERATION 

• BCM detects the combination switch condition by the combination switch reading function.

• BCM transmits the position light request signal to IPDM E/R and the combination meter via CAN communi-

cation according to the ON/OFF condition of the parking, license plate, side marker (Without Daytime run-

ning lamps) and tail lamps.

Parking, license plate, side marker and tail lamps ON condition

- Lighting switch 1ST

- Lighting switch 2ND

- Lighting switch AUTO, and the auto light function ON judgment.

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

• IPDM E/R turns the integrated tail lamp relay ON and turns the parking, license plate, side marker (without

daytime running lamps) and tail lamps ON according to the position light request signal.

• Combination meter turns the tail lamp indicator lamp ON according to the position light request signal.
