FRONT FOG LAMP SYSTEM

System Diagram

INFOID:0000000003756962

System Description

INFOID:0000000003756963

OUTLINE

Front fog lamp is controlled by combination switch reading function and front fog lamp control function of BCM,
and relay control function of IPDM E/R.
NOTE:
For Canada models, the front fog lamp is turned ON as the daytime running light. Refer to 

EXL-227, "System

Diagram"

 for the detail.

FRONT FOG LAMP OPERATION 

• BCM detects the combination switch condition by the combination switch reading function.
• BCM transmits the front fog light request signal to IPDM E/R and the combination meter (through the unified

meter and A/C amp.) with CAN communication according to the front fog lamp ON condition.

Front fog lamp ON condition

- Front fog lamp switch ON with the headlamp ON (except for the high beam ON)
• 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.

• Combination meter turns the front fog lamp indicator lamp ON according to the front fog light request signal.

Part

Description

BCM

• Judges each switch condition by the combination switch reading function.
• Judges the front fog lamp ON/OFF status according to the vehicle condition. Re-

quests the front fog lamp relay ON to IPDM E/R (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)

Refer to 

BCS-8, "System Diagram"

.

Combination meter
(Front fog lamp indicator lamp)

Turns the front fog lamp indicator lamp ON according to the request from BCM [with 
CAN communication (through the unified meter and A/C amp.)].

TURN SIGNAL AND HAZARD WARNING LAMP SYSTEM

System Diagram

INFOID:0000000003756966

System Description

INFOID:0000000003756967

OUTLINE

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

TURN SIGNAL INDICATOR LAMP AND TURN SIGNAL SOUND OPERATION

• BCM transmits the turn signal indicator lamp signal to the combination meter (through the unified meter and

A/C amp.) with CAN communication while the turn signal lamp and the hazard warning lamp operating.

• Combination meter outputs the turn signal sound with the integrated buzzer while blinking the turn signal

indicator lamp according to the turn signal indicator lamp signal.

HIGH FLASHER OPERATION (FAIL-SAFE)

• 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.
